Ordered my Bazzaz Z-Bomb today!

They have the connectors and are getting ready to start shipping! Call Tracey at Bazzaz (909-597-8300, ext. 111). She is exceptionally nice and knowledgeable (her husband is a Jordan Suzuki mech. for Roger Hayden and works at Bazzaz in the off season). There are several of you ahead of me, but she expected mine to ship within a couple of weeks. I will put it on when I swap out those ratty OEM Bridgestones for my PilotRoad 3's over the winter. It will show 3rd gear in 1st, 2nd, and 3rd, but that is a small price to get rid of the nanny throttle. You know, Kawasaki and Suzuki sell their big GT's mostly unrestricted. I fail to understand why Honda would do this instead of just installing traction control (I know, the new blue VFR's having traction control). I love this bike, but as their technological flagship, it should have had traction control, cruise control, saddle bags, etc. as standard OEM equipment in 2010 (especially at that MSRP.....I paid less than 2/3 MSRP). Ride safe.

Z-Bomb Honda VFR1200F 10-12

Hey interceptorrider, not shure who will get the first unit, I definatly ordered mine. Your discription of the folks at Bazzaz is dead on, great crew. As a DCT owner it will be an interesting installation and test. If this goes well I may buy a slip on and Fi unit. Ok I want the Fi and slip on anyway but first things first. I ride with ZX14, Busa and R1 owners amongst others and look forward to thier reactions if this all goes well.

This is easy to understand once you realize that the TC software wasn't fully developed in time for the 2010 release. Unlike other manufacturers, Honda doesn't like to release half baked solutions to let customers do the beta testing, something most of us would appreciate. The short term option was to moderate the power in the lower gears until TC was available.

It was a shicken chit, bullship solution. I like Honda's......a lot. Your suggestion is one of the reasons. There is currently 4 Honda's in the garage (3 bikes, 1 van) and I've owned over 8 others (cars and bikes). However, they effed this up on this bike. They need to fix it for the 2010-2011 owners. The bike is a great bike that is hamstrung by this solution. Perhaps they should have delayed release a year to get it right. That seems like a more "Honda" solution. I'm just sayin'................

I'm with you on the Honda fixing this. Honda should first know that VFR riders are not a new rider and usally a more seasoned rider. Therefore I don't need a Nanny. The bike is 600lbs its not a spring chicken and not what a 20-30 something dreams about. Speaking of which you reminded me its time for a Call to Honda to complain again.

Will make a call next week.

So as to the other side of the coin rather than release a half baked TC they put out a half baked 1&2 gear and pissed people off.

They wouldn't have had the snail slow sales if they hadn't restricted it in the first place.

I agree. It probably hurt sales as well as the sky high price. For that price, it should have had a centerstand, saddlebags, and cruise control. WIthout those items, it seems a couple grand cheaper would be a more appropriate price point. Again, I'm just sayin'................

You think if we started a signature list to get Honda to unrestricted 1&2 gear they might listen ?

No. I like the idea though. Anyone know how to do this online?

Didn't mean to offend you ahmageddon it is just that most VFR riders are probably a little older or a more seasoned rider many have ridden some type of motorcycle beforeis what I was implying.

As far as the Honda gear limitation maybe we can get HSlammer to make a survey and set it up as sticky and ask people to vote on it. Have it say do you agree with Honda restricting the 1&2 gears on the VFR 1200 2010. Would almost think we would get 100% results saying no I don't agree.

Will email him find out if we can get a survey going and maybe send it to honda.

Any member can start a survey/poll, just check "How to". :smile:

In case this does go to mother Honda, it might be an idea to clean up the typos in order to be taken more seriously - need a second "r" in derestrict and it is DCT, not DTC. Oh yeah, and the DCT is also a 1200F. Cheers.

tried to speak to Honda reps at Int MC show in NYC this weekend...they were extremely unreceptive, bordering on rude to me they did not want to hear about it or even acknowledge the problem... total BS !!! i am very disappointed in Honda ...makes me wonder if the have any interest at all any more in selling motorcycles.....i have owned a Honda since 1971, didn't seem to phase them....spent some time speaking to Dante at the Bazzaz booth with much better results....still don't think i should have to spend $1000 to make a $16,000 bike run correctly Honda acted like i was making this stuff up !!!!!

Given the option of TC I choose TC. I Feel that this makes Honda admit there bike was to have TC in the first place. I believe at a minimum they should remove the restriction placed on the bike. If they just fixed the restriction I would be happy.

Honda has released the ECM update in the UK where the VFR 1200 riding community has been very vocal about the 1st and 2nd low RPM issue. No idea what the hang up is in releasing the update in the US. Curious if anyone has called the Honda Customer service? Oh and I just recently got a new DCT but have not had a chance to ride much due to the recent weather in the Seattle area.

Congrats on the first post, the DCT, and Welcome to the board.

Honda is like any other major automotive producer. They will always do what's in their best interest first. That usually means what's in your's as they want to sell you their product but if they can get away with something they will.

And sales reps (of any retail product) are a total waste of time. Half the time they are ignorant of what they are selling and the other half they will tell you only what you need to hear to get a sale. So in the future don't waste your time and energy with them.

Simply start a petition and forward it to customer service when you feel you have enough signatures. Keep in mind though that even if you do get a response it won't happen quickly as it has to happen in a way that protects Honda first and you've all ready bought the bike so they won't feel the need to rush. Good luck!

Hey guys, I just received my Z-Bomb today (!). Has anyone installed this yet? Is it as simple as the directions make it seem or should I watch out for any hidden alligators? Thanks!

My Z-Bomb arrived today! Cool. I have some time off next week. Z-Bomb and Pilot Road 3's will get installed then. :fing02:

Stoopid snow.

Hi Jussi, they do not have an on/off switch. Not sure why you'd want to turn it off though...?

Jussi

Is there on/off switch in it?

Hi Jussi, they do not have an on/off switch. Not sure why you'd want to turn it off though...?

Why; With Z-Bomb your gears will show 3-3-3-4-5-6. It would be nice to turn it back to standard sometimes. You can make the switch yourself also but then we are back to cutting wires.

Well, considering most older bikes out there don't have a gear indicator and many new ones still don't I think I can live with 3rd gear showing in 1st -3rd. That was part of my thought process when ordering the Z-Bomb many months ago. I only ever really need to know what gear I'm in when on the highway, just to make sure I'm in top gear, in which case the multiple 3rd gears won't matter.

Got my Z-Bomb today in the mail. It went on in less than 2 minutes, and 1.5 of those minutes were tucking the dongles back into the frame area where they arent visble. Nice little product, well made for what it is too. It was 61 degrees in my area of Virginia today so I went for a 5 mile shot up the road once I plugged it in. I only have 800 miles on my VFR but I was already unknowingly referencing the dash indicator to check my current gear haha. The bike was definately smoother in its acceleration. But not so much from a dead stop that I'd be overly confident "racing" my unrestricted VFR12 vs. a stock one. It wasnt dangerous feeling by any means, worst case I'd say a cold tire situation with a careless rider trying to show off could result in a wheelspin event, but it's nothing scary. (Wet roads would be MUCH easier to spin on I'm sure) - but I didn't need a Z-bomb to inform me of that. Overall-good mod for the VFR, its not a faster bike because of this mod though - just smoother and I like knowing that the electronic nanny is gone (I'm 30 years old and still invincible dont you know?) Not the drastic difference I expected, I guess because 1k-5k rpms goes by so quick even when restricted, but because of the overall smooth torque range and lack of "fall over on its face 1st/2nd gear throttle twists" READ: Feels like a normal large CC bike should now, I wouldnt want to ride without it again. I will post a review update after I ride the Blue ridge this spring (Deals Gap/Dragons tail run in May as well. You guys who like to hear your engine sing need this, itsa cheap thrill. THIS IS NOT A DANGEROUS MOD IMHO

Just to let you know I talked to honda Customer service yesterday and they stated Honda doesn't really know that there is a problem because Honda isn't getting complains from riders about lagging first and second gears. You could bitch at your dealers tell your blue in the face but that isn't telling Honda there is a problem. The dealer generally doesn't tell Honda anything if they don't have too. The only true way to get them to do something was he told me that everybody should be calling the customer relations for motorcycles. They then document it. If they get enough complains they will force engineers to look at it. They have two complains from me already the first one was about 1000 miles. The last one they asked again what the mileage was and if it was still doing the same issue. I told them my mileage is now about 5k and yes the issue still is present.

So we will not get Honda to fix it or even say "yeah we know about it" unless more people start calling about it.

Just my two cents.

What a lie!!!!! Where do you think Honda gets his information to improve the VFR 1200? From forums like this!! All the improvements they made on the 2012 were discussed on this forum (slippery seat - restricted first and second gear etc.) The best and cheapest tool they can imagine to improve their product. They could at least admit that they read forums like this, that they know things can be improved...

but saying they had no complains???

At least the aftermarket is honest. They listen to us (on the forums) and provide us with the products we want.

Did some more riding today - I will repeat my earlier post in saying this little device does not make the bike "dangerous" ... my last bike was a 2007 Yamaha 1700 Warrior V-twin ... 1670cc torquemonster , that was a wheelspinner, and it was not restricted ... so, I could be a little biased. If you are used to a 600cc low compression scooter or less, then yes, I can see you being shocked at the better throttle grading that this provides in the sub 5k rpm range. It just makes the power delivery match what your right wrist is asking in the lower two gears, thats it, no raging bull surge that induces uncontrollable wheelies or unintended wheelspin. It IS a worthwhile mod however. Today I rode 20 miles or so and I dropped down to first gear going 15mph or so and cracked it and it did pull the wheel up a few inches, but I've done similar small wheelies before the z-bomb thing, it was just easier. Point of the story is, if when you ride your bike you like to crack it in second on twisty roads like I do, then get this little booger - you won't be watching the tach waiting for that 5k rpm spot to pop up. Also perform the flapper mod for the muffler and let the bike sing through both outlets from idle - 10k+ rpms and the bike just feels correct, not EPA'd / Safety committee approved and dumbed down. Hard to believe Honda markets this as a sport bike made for touring but wants to restrict it like mine used to be, I was expecting more grunt down low, it simply is not dangerous unless you weigh 100lbs and suck at riding ;)

Well, from this and the other Bazzaz thread, it looks like you folks have the ins and outs of this covered. Thought you might like to see the charts though. The upper group of each is the torque, corresponding to the values on the right side of the graph. The other is power, of course.

Finally got those connectors! Sorry to make everyone wait so long.

Well did you call Honda corp if your answer is no then they got no official complaint. This and all manufactures would treat this forums as non-official development. People weren't dissatisfied enough to lodge a formal complaint therefore the issue doesn't need to be addressed in the manner of official response. Again people can complain on the web and not even have the bike. Only people with the bike can log official complaints because it is tied to your motorcycles vin #

The Traction Control was in my believe being developed for the 2010 so to say they fixed the issue in the 2012 is just crap. They put the clipped first and second gear they fixed nothing they only finished what was to be done in the first place. IMO They clearly had a mess up in engineered project deadline.

Kudos to Bazzaz for putting out the Z bomb. While I know he makes Traction Control, I have never though I needed it. But, maybe it is like one of those options you never think you need just a nice to have feature.

Anyways my recommendation still stands Call Honda. Bitch, then tell us about it here.

Thanks Bazzaz but you need to put the Z-bomb back on the website please.

Of course if Bazzaz put a switch in the Z-Bomb (that I firmly approve of btw) we would have traction control on our pre 2012 VFR1200's :)

Peter

Bazzaz, thank you for putting up that graph! Holy cow, I can't believe the huge dips in 1st and 2nd gear. They look worse on "paper" than they feel to me I guess. I installed my Z-Bomb the other night and will get my first ride in tomorrow. I can't wait! Thank you thank you thank you for making this product available to the masses.

DCT Z-Bomb

The results of my Z-bomb instalation went south. After the install the bike did not go into gear... uninstalled the Z-bomb, all is well in Texas. FYI recorded 40.8 MPG on a ride yesterday and thats the best i;v seen.

It was never meant to be used on DCT

I ordered one yesterday.

I did ride today (nice high 50's today in VA), and while starting from a stop I had some fun and gunned it more than usual. I'm just at 900mi. I am reminded of the 2nd gear dip for sure...Looking forward to my Z-bomb delivery :tour:

Got my Bazzaz z-bomb Thursday, installed it Friday, road the bike today. Well I can say this, my vfr1200 is a much better wheelie bike now. :smile:

Your right Rice. The guy that was going to loan Bazzaz a bike to check out the compatability with a DCT did not come through soo I stepped up to give it try.

I did not intend to knock Bazzaz at all, I just wanted the "fix" :tour:

I'll call the R&D guys Monday to touch base with them.

Curious what the installation looks like? Does it involve cutting wires or is this just as simple as connecting the Z-Bomb in between two connectors? Thanks

I think it was already tried Lew. But I don't know if Bazzaz has worked on it yet.. yeah that was his big hold up he wanted the OEM connectors... He wanted it plug and play...

What an interesting news. The derestriction of the 1st and 2nd gear has been around here on this forum for almost 2 year. :tour:

I know that you have been there before Dutch and the idea is straightforward. If the connectors were readily available I suspect you'd have marketed this already. Perhaps with a fairing mounted switch marked T/C?

I had no idea It had been tried on a DCT, as a new member have I read alot and obviously missed it. :huh:

LOL no harm done. If i'm lucky i'll send the ECU to the EU for a new flash in March. Now I have to hunt down an address to send the ECU to.

Hi Guys,

I was looking forward to ordering the Z-Bomb mod, as it has now been posted on the website for sale. I was going to order two, because my buddy and I both bought one a week apart.

My question to you is... The website quotes 35 bucks for FedEx express shipping! Did you actually pay that? If I ordered one or two items, it was still 35 bucks. Just wondering how many orders they lose with that ridiculously high shipping rate? Why can't I just order the harness through Honda, and do the fix on it?

I just tell them my bike was stolen, and some parts were missing that I need to get to get it running again...

Some guys are sending there ecu's to the UK... Bazzaz is doing the same thing that dutchgixxer is doing and he said it wouldn't work in that thread... I think..... The big problem is with the DCT the bike has to know what gear the bike is in and its trying to preselect and it does both the gear above and below. I think its a constant communication system for the DCT but I really don't know first hand.

Dutchgixxer could never find a source for the connectors and it took Bazzaz close to 8 months to get his source... at least it is done now..

Thanks again Bazzaz

Yeah they seemed high on shipping,

UPS shipping to me was $7.43. By the way, this is a picture of me after my first ride with the Z-Bomb installed, complete with big smile: :tour:

Same here UPS ground shipping on mine $7.43.

Anyways, she said the shipping price would be whatever the normal FedEx rate is, and "not to worry". So I'll be ordering two. the folks on this board and elsewhere seem to be happy with their services, so I will give it a go. I'm sure most of us are savvy enough to cut the wires, but not stupid enough to lose the warranty....

Has anyone installed one with a Power Commander? Can you?

GuitarX has a power commander on his bike so yeah I'm pretty sure it works.. But PM him to make sure.

Yep, I've got a PCV and Auto Tune installed. The de-restriction is a totally separate deal and doesn't mess with the fueling. It just fools the ECU into thinking you're in 3rd gear when you're actually in 1st or 2nd. Went for my first ride today and the bike ran great. Nice difference especially in 2nd gear. This is not a super-expensive mod and I can't imagine anyone with a VFR1200F that wouldn't want to do this. It doesn't change the bike significantly or turn it into a fire-breathing monster. It just makes it react to the throttle the way you'd expect it to.

The chart makes it look as if there is upwards of 50 untapped hp in 2nd gear if you decide to roll on it... I would think that for a light to light race, this mod is going to make this bike significantly quicker....?

The difference restricted / un restricted is not that big. In all day use say touring around the block the difference is not so clear. But if you go into the mountains and you ride in a more sports style out of hairpins, the difference is very clear. The torque low down is always present. Just as to be expect with a 1200 cc engine. I have fiited an akrapovic exhaust and a PC-v. The oem lazyness lowdown is completely gone. Power output is far more liniair. So driveability has improved a lot. That is what i needed.

Why is the mod not working on a DCT model ? The aswer is simpel. If the ecu or the rider has chosen 1st gear the ecu has to know if the gear change was sucsesfull and ready. ( It is a closed loop system ). If you remove the feedback ( do the mod ) the ecu gets no feedback its waiting if the gear change was made. The DCT will not make another gear change . So a work arround is not easy you will need a "fooling" ecu that gets the gearchange triggers from the main DCT ecu.

I did manage to get the gear indicator right even with the mod applied. I have decoded the link between the ecu the tach unit and the gearposition switch. It needed a pic processor and some C++ programming to get it working.

The total extra horses will only be accessed with a wide open throttle and the engine on full load. If you start to wind it open that much in 1st and 2nd it'll be time to change up way before you get there :D

Great work re gear indicator :)

Cool. Sell that to Bazazz. Perhaps they can incorporate it into the Z-Bomb. They have the connectors now. Maybe you could work together. Nice work DutchGixxer.

Damn great job DutchGixxer and thanks for all your research. I spoke with Bazzaz they thanked me for testing the z-bomb on the DCT. Yes it was a long shot but nothin risked nothing gained. It looks as though I’m in for a FI unit with auto tune and slip-on to smooth out the bottom end.

Side note - I called Honda to express my concerns about power delivery.

For those that have installed mods, out of the available (exhaust, fuel-injection, and derestriction), which provided the most noticeable gain? I own a DCT, so the derestriction is a no-go for me (unless ECUnleashed comes through, see my other post). I'm trying to decide if a PCV and an auto-tune is worth the cash, or if I'm just wasting my time without the derestriction. Like most, I'm just hoping to firm-up the bottom end.

For overall improvement of the driveability a PC-v gives the most noticed improvement overall on a 2010 and 2011 VFR1200f. Go for a custommap forget auto tune.

Dutch, I have read that a DCT is not able to be Dyno'd ie the custom map...

Has the work around been posted? Or do you mean some one rides the bike ten goes back to the software to make changes?

Inelson, I have the three mods you mentioned. I don't know how much difference the end can made as I bought the bike with the can installed from the dealer. Since it's just a can and not a full exhaust I'm guessing it wasn't a huge difference, except in sound. For me, the de-restriction made the most difference. From looking at my before and after dyno results from the PCV/Auto Tune install, the VFR is already quite smooth throughout the rev range. The PCV added some hp but really couldn't smooth things out much more than they already were, therefore the bike didn't feel much different. Getting rid of the power dips in 1st and 2nd gear due to the artificial restrictions made a difference I could easily notice. If I had to choose one of those three mods, it would be the Z-Bomb.

It is possible to dyno a DCT. You have to fool de ECU : take the ABS sensor and sensor ring. Make an interface ring and holder and attach them on the rear wheel.

The ecu "thinks" that the front wheel is turning and the DCT will shift gears.

I have dynoed my mates DCT it took some effort but we have managed it :rolleyes:

tried to speak to Honda reps at Int MC show in NYC this weekend...they were extremely unreceptive, bordering on rude to me they did not want to hear about it or even acknowledge the problem... total BS !!! i am very disappointed in Honda ...makes me wonder if the have any interest at all any more in selling motorcycles.....i have owned a Honda since 1971, didn't seem to phase them....spent some time speaking to Dante at the Bazzaz booth with much better results....still don't think i should have to spend $1000 to make a $16,000 bike run correctly Honda acted like i was making this stuff up !!!!!

Their reaction is classic. No business wants their "laundry" aired in public at an event where they are promoting their product. While I appreciate your passion, Honda's reaction is pretty normal. Honda has often been slow to react to problems. I also own a 2008 Accord and a class action suit was filed and won to ensure that repairs to my rear brakes due to a dragging pad problem were covered by Honda. I think Honda would have resolved it through a recall program eventually, but the suit forced their hand.

Went for my first ride today and the bike ran great.

The cold air probably helps the motor, not so much the rider!

I ordered two z-bombs today... Unless someone gets a picture install before, I will post one after the mod.

P.S. My buddy put one of those DAM exhausts on his vfr1200, and it sounds sweet. I can now hear him coming from a couple blocks away. Before, I couldn't hear him on my porch... :-) The DAM tucks in closer to the wheel, and doesn't use springs like the other exhausts. It looks to be of good quality.

Installed mine yesterday, I'll be giving it a quick test today.

I received the z-bomb today. 10 minutes later I was testing it in 35 degree weather. It definitely smoothed out the power delivery from down low in 1st and even more noticeably in 2nd. It did NOT turn the bike into an uncontrollable beast. If anything, it feels more manageable since the power delivery is more linear. It really is hard to figure out why Honda neutered the bike so much in that rpm range in 1st and 2nd. Most of our twisties are open enough that 3rd is "the gear" to be in. So, the 1st, 2nd neutering wasn't a huge deal. I loved the bike before and now its even better. Definitely worth the $73.00.

$73 ! ? :blink:

Cost including shipping for a plug and play solution. Instalation takes 4 minutes. If I want it removed, it would takes 3 minutes. Your solution is cheaper, but reversal is a tad more time. Your work on this has been very helpful to all of us. Thank you Dutchgixxer.

Hello all,

I never posted my opinion...Well here it is: THIS THING IS THE BOMB!

Definitely worth every penny. Cleaned up the power in 1st and 2nd as advertised.

I Highly recommend this one.

I ordered one - most of my surging and lagging issues were solved when I took the oem muffler off and replaced it with the leo vince but there is still a bit of lag in 2nd gear. I looked hard at the dutchgixxer mod but well Iike the gear indicator to work correctly - I am a bit anal about that. I just had a few issues when I started to pass a car in the mountains from a slow start 25 mph in 2nd gear and then I twisted the throttle and it lagged on me for bit - dont want that to happen anymore, nothing worse then pulling out into the other lane to go around a car and you get a little power lag! Of course it spooled up but it wasn't instant like it needs to be. The old girl 1998 never once did that to me!

It just seemed the fueling went into some kind of saver mode and had to be coaxed out of it to get the power on. It was worse with the flapper valve in the oem exhaust hated that - it did not help low rpm torque at all it just smothered it. It usually does not happen cause I tend to not let the bike rev so low or I am already spooled up before I try a pass. Honestly it has more passing power in 4th then 2nd sometimes.

Do you realise Miguel that the Z Bomb also gives incorrect gear display in 1st and 2nd?

Mine arrived today and I'll fit it once the bike is through the initial service.

NO - Damnit, I looked for a description! Well I dont have to cut more wires on the girl.

Well the bike only has 2 gears anyway, the right one and the wrong one :)

As Dutchgixxer explained, getting the gear indicator to read correctly isn't a straightforward task.

Dutchgixxer

I did manage to get the gear indicator right even with the mod applied. I have decoded the link between the ecu the tach unit and the gearposition switch. It needed a pic processor and some C++ programming to get it working.

Dutchgixxer, would you post schematic / instructions for gear indicator?

http://www.vfrdiscus...cut-eliminator/

I'm sure that fuel cutting is an issue on the VFR (as it is with most if not all FI vehicles) but it's also, and more significantly I feel, severely restricted at the lower rpms in 1st and 2nd gear. The wireless throttle is apparently 'detuned' by about 60% in these conditions. The fuel cut eliminator may help overall but it won't overcome this particular restriction.

Peter

I put this Z Bomb on a couple weeks ago... I was hoping for some umpffff.... Unintended wheel spin? LOL!!! It sure didn't do much for me, but maybe i run it too hard already.

If you want unintended wheelspin, you should have gotten an inline 4...

I must say though, this vfr1200 is one smooth as butter riding machine. I hit 140mph, and it was smooooooth...

Peter

<repeat from other thread>

The device is called a Fuel Cut Eliminator based on the problem they were originally designed to solve. The functionality has expanded to cover applications like this.

For example, the Bazzazz unit just changes the wiring to fool the ECM into using the 3rd gear map. Ivan's FCE's do this electronically to use the 5th gear map.

Could they make one for the VFR? I'd like to see them give it a try because I just put money down on a DCT model.

You can keep repeating all you want, you can even try shouting (I'm told it works with us 'foreigners' :) ). I'm aware of the FCE and what it seeks to achieve. Fuel cut elimination will smooth out the throttle response no doubt but that really isn't the issue here. Okay you talk about expanding to cover applications 'like this'. You then go on to talk about 3rd gear map and 5th gear map.There is only the ONE map (so the 3rd gear map and the 5th gear map will be one and the same). Honda have used the wireless technology incorporated in the throttle mechanism to restrict the bike. In 1st, 2nd and 6th gear under certain conditions (rpm in the 1st and 2nd gear situation) the relationship between the twistgrip and the throttle body butterflies is altered. This is where the restriction comes from and this restriction is not due in any way to fuel cut.

Anything that piggybacks the ECU and addresses the situation that is more than a simply re-connect won't be a FCE, although of course it may incorporate one.

Of course a simpler way to overcome the restriction to to reconfigure the wireless throttle to be linear at all times and in all gears. A separate FCE would then have a place. In fact FCE's are no doubt a valid consideration in addition to derestriction.

Peter

My initial service was done last Thursday and the Garmin harness is fitted.

I popped into the garage last night and took 10 minutes to fit the Z bomb. It was a bit of a fiddle to get the new males into the existing female but it clicked into place and it's all neatly tucked away.

Sun is shining this morning and we'll be out soon. Will report back.

I did about 150 miles yesterday with the Bazzaz fitted. Roads ranged from single track with lots of tight bends and gravel to fast sweepers. I noticed straightaway that the bike seemed more normal in it's 1st and 2nd gear pickup especially compared to 3rd. Riding some really gnarly stuff that challenged the Viffer a bit the reinstated torque never gave a moments problem.

Bike is simply nicer to ride, that's it.

I found it to be a real non event. You will definately not unleash the beast. No unintended wheelspin or wheelies! It is a really fun bike to ride though...

Does anyone know if the gear indicator issue has been corrected or if it's being addressed. It seems this modification has value, but I'm hoping the existing (gear indicator) functionality isn't compromised permanently. Thank you.

I don't think the gear indicator issue has been fixed, and there's probably not a great deal of push to do so. I would personally like to see it, as well. Having said that, I ordered the z-bomb last week, and am looking forward to riding with it installed.

I've felt the "hole" in second. Not good. Equally irritating is the jerkiness in first. I thought it might just be me, initially. You know, not being smooth enough with the throttle. Maybe it's a bit of both!

I'll report my findings once it's here and installed. Looking forward to it, but I am a bit intimidated by the thought of unintended wheelies. Last time I did one intentionally was on a Schwinn in 1976.

I don't think that the gear indication issue is an easy fix, certainly not one that Bazzaz will do I suspect.

If you're using mph and not kph there's a helpful hint. In 2nd revs and speed match just about exactly. i.e. 10mph @ 1,000 rpm, 30mph and 3,000 rpm etc. In 1st it's easy to tell methinks. In 3rd revs and mph don't match and in 4th and up it says so.

The really useful one to my mind is 6th gear.

All bikes only have two gears any way, the right gear and the wrong gear :)

Peter

The gear indicator issue is a NON ISSUE. Don't look at it and ride the bike by feel like we used to do when they had kick starters.

Hands down the best money I have ever spent on the bike

I've been riding slipper clutches for years (Aprilia Mille & Futura), but I still don't trust an unexpected 1st gear down shift when it's not expected. I've done it once on this bike already, with the gear indicator working, and thankfully with not even a glimmer of mishap, but that doesn't mean it might not cause an issue next time.

I got mine a week ago and tested it immediately - very noticeable difference in 1st and 2nd gear, no power drop, no jerking. Also the sound improved a lot, it gave it more roaring I guess because the valve opens more often. I don't know about unintended wheelies but at one point in 2nd gear I was very close to slipping off my seat and falling behind the bike while it was accelerating. :-) I would definitely recommend the Z-Bomb to a friend!

I think it'll be a good addition. I've never been one to "stunt" a bike, but I do appreciate pure power and performance (including speed)

My adversion to wheelies is based on several things, I suppose. Not the least is that I remind myself of Danny Glover's line in the Lethal Weapon movies; "Im getting too old for this sh#t!" lol

Our bike does have a slipper clutch as well. I tested it once (in the 1st 30 miles of ownership). Works good. Lasts long time.

By far the best money I ever spend on any bike compared to level of improvement, I think though that if the people @ Bazzaz designed so the 1st and 2nd gear sensors attached to the 6th instead of the 3rd the power delivery would be the same but the indicator will read 6 - 6 3 4 5 6 instead of now 3 - 3 3 4 5 6. You can't mistake 1st or 2nd for 6th as it can happen now with 2nd 3rd.

I am actually using km/h, but I don't really care about the indicator, I am more looking at this from a tecnical point, as when I drive I prefer to look at the road and drive by feel as I did for almost 30 years before this gadget, The only time I find the indicator usefull is to make sure I am running on top gear since this VFR engine is so smooth that you can easily run on 5th for 10 min. and you won't even notice otherwise.

I rode HS 1200 at the Tmac for a little while and it is a beast!!! Love that engine, very addicting power.

Mine has the zbomb, and a leo vince with no exhaust flapper.

HS- any issues with the gear indicator? I'm really wanting to head this direction, but am a little hesitant due to this. I know you (seemed) to feel the same way early on. What are your impressions now?

To me Honda stop listening to the riders when they introduced Vtec in 2002, very sad.

[image: 0319121337b-1.jpg]Hi, I just received my Zbomb. I have this and the Leo Vince with no flapper too.

It was smoother and pulled stronger in first and second. But not, why is my rear wheel passing me strong..

I guess I'll have to get a ZX14 if I want to unlease a beast!

I don't miss the gear shift indicator. I don't know why I was such a pussy about loosing that. It's more of a distraction now. I don't look at anything but how much of a speeding ticket I'm going to get! I could do with just a neutral light, gas guage, engine temp and mph and I would be happy!

Over all I would do it again in a New York Minute!

Thanks Dutch for all your work and to Bazzaz for such an easy 15 minute install!

The VFR1200 rides like a cadillac. That being said, it puts me to sleep. The ZX14 (bagger) is in the furure...

As I've mentioned, I have the z-bomb installed on my V12, and I do like the difference it's made. I do have a question about it's use with a PCV. Should I remove the z-bomb for the initial PCV install?

I'll be using the 2-Bros map to accommodate my Leo Vince slip on.

If it makes a difference, someone let me know; I'd be appreciative. Of course, I would reinstall the z-bomb after the PCV install. Is there anything I'm missing?

Once the PV5 is installed, I'm down to about three more mods remaining!

Thanks

Leave it on. It is independent of the PCV. They do two different things. The PCV alters the fuel map (adds fuel according to it's own map). The Z-bomb tells it to use the 3rd gear map in 1st and 2nd. I have both and like them. Actually, I should change the map on PCV as I am running a LeoVince pipe now. The fueling stills seems good. I'm sure there is a better map for that configuration though.

Ride safe.

Interceptorridder, thanks for the suggestion. I'll leave the z-bomb be, and do the PCV install as I originally intended. I'm going with the 2 Bros map, simply because it appears the be the closest thing available.

The Akra pipe uses the flapper system of the original equipment, and the only other map I can find is the Jardine. Going to have to dust off a PC laptop, as the PCV software is not Mac compatible. Looking forward to smoothing the fueling out. Any performance increase is icing on the cake.

Had a chance to meet Bazzaz at a AMA race and he is really nice guy. He does all the Fuel controllers for the Jordan Race Team. He gave me a discount card for his products and in the future will definitely consider them.

New poster here...just wanted to throw in my .02. Installed the zbomb a couple thousand miles ago....BEST money for the performance I've ever spent. I dont't care about the gear indicator as this is my first bike that has one. In my opinion....great thrust in 2nd gear..waaaay better than stock..but not sooo much that the thing is out of control. Reminds me of my old ZX-11. Also, did the flapper mod....BEST free mod i've ever done!! Bike sounds like a bike now.

The Z-Bomb seems like a nice easy solution to the power restriction in 1st and 2nd gear. I'll look more seriously at it once I'm through the break-in period on my bike and can get on it a bit.

My concern is that Mr. Honda implemented this restriction due to some mechanical weak point and not 'wheelspining power' in low gears. Is there any concern about extra strain/backlash on the drive shaft due to this mod?

I felt the bike was borderline dangerous with the power restricted. There was no smooth transition from restricted power to full power. If I twist the throttle full open it was very hard to predict when I was going to get full power in 2nd gear...it was like one moment I get partial power, then, with no change in throttle postion someone flips a switch and I get a handful of power. With the bike derestricted I now control the power...If I want full power I get it...if i want less power I control it. Im willing to take a chance on the extra wear and tear this increased power might do in order to safely regulate the amount of power im getting myself. On a side note I think the best setup would be to leave 1st gear restricted and only derestrict 2nd gear by making the indicator indicate 6th gear in 2nd gear so that it reads 1-6-3-4-5-6. Just my .02.

Bingo My thoughts exactly except I never had a ZX-11 old or new. The throttle doesn't seem nearly as jerky now either.

Went to install the Bazzaz today... I found the connector (I think) but I cannot seem to get enough slack in the wires to her the connector apart. The connector seems to be tied to something behind the frame. Is there something I'm missing or is it just going to take some bruit force to pull the connection apart? I AM pushing the button to release the connector... Just no dice.

Is there any work to correct the Gear indicator display with the Z-Bomb?

No.

Sent from my SAMSUNG Galaxy SIII using Tapatalk 2

Is the gear indicator a big deal? NO. Do I sometimes wish it were there? YES...

I am new here and just looking for information to decide whether to buy a new VFR12 or a used or leftover earlier model. If the new model has traction control did they unrestrict the power in the 1st 3 gears. In other words will the new bike run as hard in the lower gears (assuming traction is not an issue) as one of the earlier bikes with a Z bomb??

I need help. Have the zbomb but cannot access the harness in my bike to connect it. Looks like it is deep under the chassis and cannot reach it with my fingers. Hoe did you manage to take it out ? Thanks

Can any shed some light on this please? Everybody says it is a 5 minutes job and I have been half an hour trying to reach the harness unsuccessfully. i feel like a dumb. help me please!

Regatillo:  The connectors are indeed buried behind the frame.  It's a very tight fit to get your fingers in there.  The good news is the connectors are attached to the frame with a removable bracket, so first unhook the bracket - this will allow the connectors to move and make it much easier to disconnect them (I didn't figure that out until busting my knuckles for a hour..)

Good luck.

Zbom for sale...

Hahahahaha :beer:

Am now looking for faults that I didn't even know existed on my bike, damn it sometimes ignorance is bliss :) oh well gives me something to read up on now!

So I've depleted my motorcycle fund with a trip to the track at Barber Motorsports and wasn't able to reflash the ECU this winter. So I bought a Z-Bomb.

As soon as I have time to take a last refresher ride (I'm in Chicago and had 3 rides in February!) - the snow is thick right now - I will go for a decent local ride, then add the z-bomb and take the identical ride to compare.

Will report once installed and tested for those who are still on the stock ECU without Z-Bomb.

Will try to install tonight. Rode a bunch over the weekend as a baseline, hope to report after the rain ends here in Chicagoland.

JEEZ! Slow going. Installed last night late, but rain this morning so I didn't ride to work. Hopefully I'll get a ride in tonight.

Installation was OK, a little difficult figuring out how to unhook the original connectors. So I attached the Z-Bomb's connectors to eachother and made sure I understood which release needed to be pushed. Made the difference.

The original connectors had plenty of slack to pull them out from the piece of plastic protecting them, and it was easy to tuck everything else back in over the plastic piece.

Looking forward to riding it!!!!

I know this entire topic is obsolete now that a reflash is available, but I went for the Z-Bomb because I had an E-Bay gift certificate for $50 and blew my motorcycle budget wad on track days.

I have to say, people pay lots of money for the type of improvement the Z-Bomb gives. The hesitation in 1 and 2 is gone, and the power is now much more accessible. At slow, easy pace riding, this won't make a bit of difference. BUT - for those that like to accelerate up the gears and give a bit of go juice to jump ahead, this is a SERIOUS upgrade. I knew what to expect from reading above, but I was still ridiculously impressed with the improvements to power delivery in 1st and 2nd gear. What was Honda thinking???

Now I really want the Guel (SP?) reflash, as it supposedly has more aggressive timing available, in addition to a bunch of other convenience items (gear indicator works, speed limits removed, fan temp adjustable, exhaust servo-alert can be killed if you want to remove the servo motor completely, etc.).

People pay a lot more than $50 to get the types of improvements made available by the Z-Bomb...  I can see that the easy access to power could be a little dangerous to an inexperienced rider, but really, what was Honda thinking?!?!?

Great mod - I now understand why it was such a big deal when it came out. (I drive a 2010 F with the only performance mod being an open flapper in the exhaust).
