I finally have some time to work in the garage and I have spent plenty of time collecting parts, so it's time to get the hands dirty and get something done. Last fall I picked up a '94 VFR750 for $200 from what I would classify as a world class crack house. No title or keys (I did check the VIN and it had not been reported as stolen). It had been wrecked, and probably flipped. The fairings were in pieces (and had a nasty black rattle can paint job). Plenty was broken, including the right clip on and right rear set. The front wheel doesn't sit straight in the forks. There is plenty of dirt and cat hair everywhere. The tank is dented to death. It does run... I was able to get it started before I began disassembly.

So, I bought it with the plan to completely disassemble and reassemble as a street fighter. I have made a lot of eBay purchases in preparation for getting it together and looking just like I want. Here's the list of purchases as I can remember from my desk at work:

  1. Right rear set including brake master
  2. Right clip on
  3. Both sets of handlebar switches
  4. CBR1000RR subframe (2, don't ask)
  5. CBR1000RR Muffler
  6. CBR1000RR Rear Fairing
  7. CBR1000RR seats
  8. After Market CBR1000RR taillight
  9. Used Tank, red with nice paint and only a slight dent that will be covered by a tank protector sticker
  10. Superbike bars and 2 sets of ATV risers (still deciding on clips ons or bars)
  11. Hayabusa GSX 1300 R emission plate pair block-off
  12. Cafe Racer Bar End mirrors
  13. '96 frame, subframe, forks and front axle with title

Here's the plans I have so far: (not in order)

  1. Install CBR1000RR subframe onto VFR frame (This is the part I am most concerned about, I can weld steel but not aluminum).
  2. Have mid pipe custom bent for CBR1000RR muffler.
  3. Install braided brakelines.
  4. Transfer engine and swing arm to new ('96) frame
  5. Clean everything, flush and replace all fluids
  6. Replace valve cover gaskets
  7. Figure out gauges and headlight
  8. Create custom belly pan
  9. Relocate or remove oil cooler (opinions please)
  10. Replace tires
  11. Finish De-Pairing

Here's some pics:

I'm planning to get the engine out tonight and remove the swing arm to give everything a good cleaning. I ordered the Swingarm and Engine locknut tools from eBay. They don't have the offset, but hopefully I can figure out the correct torque for installation with an offset calc.

I would appreciate any tips or suggestions you guys have for me as I embark on this mission.

#2

For $200 it's worth a shot. Did you check to make sure there weren't any cracks in the frame?

And that plan list is probably going to quadruple once you actually start getting into it.

Good luck!

#4

You Sir, are a glutton for punishment. Best of luck.

#5

I just noticed you didn't mention a front end. Any plans with that?

#6

Ok, so I've made some progress... Hopefully will make some more as the evening rolls on.

The swingarm is off

[image: 6960490613_509b4ff6f0_d.jpg]

The large Allen socket at the end of the swingarm made me scratch my head for a bit. But I figured out that the subframe bolts could help me when used in conjunction with a 14mm wrench.

[image: 6960496183_de8fefcd5b.jpg]

[image: 6960492205_441fc50aef.jpg]

So the swingarm is off, along with the headers, oil cooler and radiator. Now you can see how much dirt and oil is all over everywhere. I'm pretty confident that the oil leak is isolated to the valve covers.

[image: 6814374394_69868be076.jpg]

[image: 6960489065_977a5a2726.jpg]

I think I am ready to drop the engine out of the frame... I hope.

I picked a '96 frame that's in great shape and hasn't been wrecked. That will be the frame I go with.

YoshiHNS

I just noticed you didn't mention a front end. Any plans with that?

The plan for now is to use the '96 front end that came with the titled frame I bought as they are in good shape. I may respring and revalve if needed. Same with the rear shock... It's still TBD.

#9

Well, the motor is out of the frame. I'm done for the night. Things went pretty much as planned... No real surprises so far. Just a lot of grease and grime. I have lots of degreaser for this project.

My garage was quite clean before starting this project and the XR200R restoration. I probably need todo some garage cleaning before I dig much deeper into project land.

#10

phew, that's awesome! I think I might have hit her up with the pressure washer and degreaser before disassembly....but I know the feeling you had....I love diving into a project like this!! Any pictures beforehand??

I had some before pics from when I bought it, which was a while ago, but they never made it off my phone and got lost.

The thought of cleaning it before disassembly made me nervous with the potential for water and junk to get where it didn't belong. I felt like I had a little more control of it this way... Of course, cleaning it first would have saved me the from the near permanent black fingernail outlines I have today.

#12

I just dug a before pic up from my Dropbox... I didnt think I still had this!

[image: 6815469210_dd87a96ac2.jpg]

#13

Yes, these types of projects are WONDERFUL for the nail brush business....scrub brush business in this case. Been there, done that. Someone really didn't take good care of that poor ole girl did they?

any savable plastics off her?

#14

The only plastic i've saved is the front fender and it's cracked. Most fairings were all brittle and cracked. The seat is decent, a little vinyl conditioner would probably do a lot for it. It's a Corbin Gunfighter I think.

#15

I think I just scored a sweet deal on a full gasket set on eBay! I got it for about $140 shipped. I saw several top end only kits for over $200... hopefully this one isn't crap. I was going to just pick up the valve cover gaskets and those were going to be over $60 so I started looking at top end kits and couldn't find an answer as to what was in the kit. So, I figured $140 bucks for never needing to hunt down another gasket sounded pretty nice.

[image: 88_1_b.JPG]

#16

It's an ok price. If it's good quality it really doesn't matter though. It's not something you want to be doing again down the road.

Indeed!

I hadn't planned on doing the head gasket, but the kit comes with it so it may be worth doing just to make sure they're in good shape. Any thoughts on doing the head gasket just because? Is it overly difficult?

I know I want to take the clutch cover, the crankcase cover and the stator cover off and paint them, probably with crinkle paint. The cylinder covers will probably get a coat of that as well. So having all these gaskets will make it easy to do all that without having to source a gasket every time.

#18

i've heard of some guys removing the oil cooler completely on fighters. i think hyofighter relocated his cooler to the side, check out his fighter build for some good ideas. Due to an incompetent driver in a parking lot i had my plastics removed by force (thankfully i wasn't on the bike when it happened). I ran my bike for a while without plastics and found that it ran much cooler (as you would expect). Cool enough where i would confidently say that an oil cooler isn't necessary if you don't have the plastics. My gauge would get maybe a quarter way above cold when riding. The only time i saw it get close to half way (normal when i had the plastics on) was in some very slow moving town traffic.

As far as street fighting goes, I've been prowling this forum and found some neat ideas you might want to consider. There is a thread here on COPs (coil on plugs). i am going to start looking in to this for my fighter project when i find the time. Also SEBSPEED makes this nice see-through clutch cover.

Well good luck with the build

matt

#19

Thanks Matt! I appreciate your experience with the engine temp.

I have seen HYO's work and it is fantastic. I don't think I want to try fabbing my own oil cooler. I think I will probably just cut off the oil cooler pipes and connect them together at the bottom with a length of hose and some hose clamps.

I've been pretty active on the COP mod thread... I am hoping someone can make it work long term. I guess we'll just have to wait and see.

If you've gone this far, who needs a leak? Replacing the gaskets is fairly easy, just a lot of cleaning and scraping to get everything nice and shiny for the new gaskets to seat on.

If you have access to a sandblaster, that's what I did for all my covers that I painted with the crinkle paint. The rough surface really likes to take paint.

You can bake the covers a couple days after painting them (200'F for 1 hour), or install them on the bike and let engine heat cure the paint. It's really smelly though.

Keep in mind the crinkle paint is very slow drying, so if you can paint the parts and set them aside for a few days, so much the better.

#21

If your going to remove the cooler and since you already have the engine out just block off the cooler ports and run a vf750c oil pump instead. They dont have a cooler loop.

I probably will pick up a small sandblaster from china freight..

Can you bake crinkle painted items in your house oven... Or is that grounds for the wifey to throw my stuff out on the lawn?

#23

I used the house oven, but opened the windows and it was no big deal. The smell goes away and there is no residue left in the oven.

Don't forget to degrease before paint! I used brake cleaner spray.

Your wife may vary.

I just looked at eBay and it looks like I can get one of these for pretty cheap. Is this a direct bolt up solution? I'll do some searching and see what comes up. It would be awesome to eliminate the oil cooler all together.

vf pump next to vfr pump. retains the water pump drive.. the vf case is the same as a vfr but machined for a cam chain not a gear drive.

*edit* vf pump is on the right, vfr on the left. U can see the non-machined holes in the vf pump.

Ok... So is this as easy as dropping the oil pan and replacing the pump? Did you do this in conjunction with the cooler on the filter?

And what year oil pump?

#27

I have yet to actually install the pump. The ngine is in mynstorage unit right now lol. I have, however, placed them side by side andnmeasured all pertinent dimensions and they are identical. The 750c uses our block with a little less machining done to it. Both feed pumps are dimensionally the same.

Yes, i will be doing this in conjunction with the sandwich cooler. I have pondered lowering the sprocket ratio on it so the oil pump (and coincidentally the water pump) spin faster so i dont have to try and find a damn rc30 pump for it but it might not even be necessary. There was concern with someone inwas speaking with that the vfr pump might not flow enough. Real life trials willprove or disprove this.

#28

I believe that pump was a 96 but check the pictures first. Youll be able to tell right away if it is right or wrong.

#29

Also, you MiGHT have to remove the clutch to change it. The chain may not be very forgiving.

#30

So are you planning on riding this bike on the road, or is this to be a track only bike?

All road riding... I doubt I'll ever get away to the track, although it would be lots of fun.

#32

Got some cleaning done tonight. What a nasty mess!

This is looking a whole lot better... Not all the way clean but it's pretty impressive what some degreaser, some brake cleaner and some engine bright can do!

[image: 6819725648_a2654de76d.jpg]

The cylinder head covers looked like they were painted black before... Now they just need some sandblasting then a nice happy coat of crinkle paint.

[image: 6965847451_5ab259e24a.jpg]

I had no idea the plastic guard between the disc and the sprocket was white!

[image: 6965848743_017c728067.jpg]

I found this when I was cleaning... It looks like the chain dug into the swingarm at some point. I'll have to look at it closely when input it back together.

[image: 6819728900_bc96cf0e9f.jpg]

I loosened the clamps on all four carb boots and gave them a tug, but couldn't get them off. I'll have to do some searching for tip and tricks on getting them off. I am planning to pull the heads too, is it a problem to take the off with the heads?

#33

you should really replace those boots. when i bought them i spent less than 50 bux for all 4.

#34
flyguyeddy

Sounds like a good plan... Got a good source?

#35

If the sawing into the swingarm isn't too bad, you may just get by with a new rubber chain guide.

#36

My source was a local pArts shop lol. I donT know where they ordered them from tho.

#37

wow, what a difference!

#38

Found em on eBay last night for about $50... They're new but hopefully they haven't been sitting on a shelf for the last 18 years.

mcrwt644

wow, what a difference!

Thanks! I'm pretty excited about the progress so far. The Engine Brite probably made the most difference... The problem was getting the motor out of the garage into the driveway so I could rinse it after spraying it down. That suckers heavy!

I checked Jamie Daugherty's instructions on removing the carbs found here:

http://www.daughertymotorsports.com/howto/Carbs/carbs.html

His instructions are good, but prying the carbs out relies on the motor being in the frame and obviously mine is out. I'm planning to pull the heads just to give them a good look and swap out the gaskets with the new ones that are coming in my full gasket kit. So I guess I can pull the carbs when I am pulling out the heads.

Now that everything is clean, I can see that the clutch cover has been sealed with RTV crap... Is this standard? Seems like it could make a huge mess inside that could have undesirable results. I'm hoping there's a gasket for this so I don't have to mess with the goop.

There's definitely a gasket that goes there.

#40

+1. Also, if you go sans gasket you might have starter gear binding issues. Best way ive found to put them on is spray adhesive to one side so it stays on the cover and lightly grease the other side so it doesnt stick to the block (but will still seal)

#41

I'll put rtv around certain areas (mostly around the mounting 'pin' holes) to help hold the gasket in place. Otherwise, put it on, and torque to spec in an X pattern. I personally do a 2 stage torque, but that's just me.

#42

Ok, so I was perusing the service manual yesterday and came across the oil flow diagram. If I am reading this correctly it looks to me like simply blocking off the oil cooler lines shouldn't affect the oil flow through the rest of the engine. I marked the block on points on the diagram in orange... Am I totally off base here or is this is legitimate theory?

[image: 6969490169_0ea3e6d0c6_b_d.jpg]

#43

you cant just block them off. there is still a pump that will be turning in there, and whatever it pumps will be sent out of the relief valve. which is a really good way to heat up the oil. just swap the pump youll be better off.

#44

From what it looks like, if you block off the oil cooler, you may get extra oil pressure to the rest of the system. That could be a good thing, but it could also be very bad.

Good point...

nitrousva

That could be a good thing, but it could also be very bad.

Hard to be wrong when you take both sides! Good strategy :tongue:

I'm watching a VF750 pump on the eBay... we shall see. I am also planning to put a belly pan on this bike, so simply running a hose from the output to the input on the oil cooler loop would not be a huge deal for me as it will be covered. I wonder if I will run into over pressurization with that method as well... has anyone done either of these mods to the oil cooler? what was the result? :lurk:

#46

Coolers get looped all the time w no adverse effects. Vf750c has none and they do just fine

#47
nitrousva

From what it looks like, if you block off the oil cooler, you may get extra oil pressure to the rest of the system. That could be a good thing, but it could also be very bad.

False. The relief valve controls this and f anything would just be dumping out extra oil. But sincebthe cooler isnt looping back into the primary feed then that wont happen.

So you're saying blocking of the cooler in and out should have no adverse affect on the pump or the oil distribution through the engine?

#49

no im saying do NOT do that. ;loop them..

#50

As far as the oil cooler is concerned, mine is just relocated low near the inlet and outlet. I did run across someone else with a very similar bike that just had the cooler bypassed. There was a U pipe that went straight (well, bent I guess since it's a U) from one side to the other. He said he'd been riding it that way every day for a year, in Florida. . .

#51

Update time!!! Over the weekend I found time to get the carbs and the heads off.

[image: 6831900170_6a5dfedf87.jpg]

it Is absolutely amazing to me just how cool the motors are on the inside. It's also amazing that this motor has close to 70,000 miles on it and it is showing zero signs of wear. I have yet to check the valve clearance but the gears are still sharp and perfect... I'm in awe. A true testament to just how bulletproof these VFRs are.

I may mor may not have forgotten which way to turn bolts to loosen them during the removal process... Righty loosey right? These little bolt removers from lowes, along with a carbide tipped masonry bit made very short work of getting the broken, grade 10 bolts out.

[image: 6831916392_397e518ee9.jpg]

#52

I'm thinking about throwing a coat of paint on the motor before starting to reassemble everything. I am probably going to go either cast aluminum silver or a nice black. Dupli-Color has an engine paint with ceramic in it and VHT has multiple engine enamel choices as well.

Who has painted their V-Four? What was the result and how did it last?

#53

I painted mine with engine paint silver but i havnt ran it so its not been baked on. Ill probably soda blast it and repaint it with a two part epoxy based paint. The valve covers i painted black got all flakey and looked like ass.

#54

I've ordered a VF750C oil pump to try and bypass and block off the oil cooler. Has anyone tried this mod before? Or am I blazing a trail here?

[image: 7001780019_a25d0468bc.jpg]

#55

I havnt installed it but it will work fine. Just block off the external cooler ports and leave out the little tubes that go to them. Vf750c and vfr = same engine block (casting and some machining at least), same oil pan, same pickup tube, same oil feed tube, same water pump, ect. You could theoreticlly use the vf750c sprocket cover and pushrod for a cable clutch conversion (but you lose the speedo pickup).

#56

Well im wrong about the oil pan being the same, but i can assure you that the pump will bolt right in. Ill do it on my empty case and post pictures.

#57

And upon further inspection the only difference between the vf and vfr pan is drain bolt location.

#58

Oooooh! +1 to that!

#60

Wait, didn't the VF's have a hydraulic clutch?

#61

He's talking about the Magna

#62

No they are cable. But the vf cover is all chrome and stupid looking. If someone were to dechrone it and possibly trim it down a bit it might look better on a vfr. Plus the cable holder bolts to either the block mount or the head i cant remember. But i think it has to be in between the engine and the frame. Ill hafta look at my buddys bike again to be sure.

#63

Here's a 1995 VF750C sprocket cover that shows the cable attachment point, and looking at the pics of the inside of it, it would indeed be close to a bolt-on, you might even be able to add a hole to incorporate the speedo drive unit. Definitely worth further investigation.

Apologies to OP for thread hijack!

[image: 302.jpg]

#64

Why would you want to get rid of the hydraulic clutch?

#65

When I first read about cable clutch conversions (done by Durbahn in Germany) I thought the same thing - the reason is that a cable clutch gives vastly superior feel over a hydraulic clutch. In addition you lose the extra weight of the hydraulic bits.

Durbahn's conversion kit for VFRs is beautifully made, but quite expensive.

#66

Didn't notice the "C" on the end of VF750. May have to look into this, I'd love to get rid of the hydraulic clutch on mine.

#67

It would look really out of place tho.

#68

How about a simple trim of what you have already?...

I prefer the reliability of the current hydraulic set up.

[image: post-5025-0-59781900-1332607562.jpg]

Here is a magnesium RC item fitted to a 4th gen-

Our 3/4th gens ones are basically the same, trim away - if you dont need your speedo drive obviously.

GPS from a mobile for a speedo works well if the bike goes on the public roads.

With only revs and oil temp on dash a mobile sits fine with Velcro on dash (thanks to NASA lol)

But its never on, no upper speed limits here.

Preferred over any magnet/wheel set up ive ever used - which has never really worked anyway.

The water pump will be history soon ......electric replacement ordered.

#69

Hey kgs, are you running a fuel pump on your bike or is it gravity fed?

#70

Pump right now. standard tank. Its the white elephant.

With RC tanks costing the price of a small country. not too fussed... Am not trying to build an rc copy... no ty. More about using wot we got first.

New battery weights the same as the pump/filter give or take 30g so be nice to get rid. But thats coupled with tank at the moment.

Would drilling a breather hole in top of tank work for gravity fed? might consider chucking pump then..but i guess there may be tap or carb flooding issues?

#71

I've been running gravity feed with the factory unmodified tank for some time. Fuel pump on these bikes is useless, just one more thing to fail.

#72

I've been running gravity feed with the factory unmodified tank for some time. Fuel pump on these bikes is useless, just one more thing to fail.

Have you run your bike at the track? Just wondering if its an issue under hard cornering/braking etc. I'm pretty sure the tank is vented already, so I don't think an additional breather is necessary. I can't imagine there being a flooding issue whilst the bike is running with gravity feed. I know there have been issues with NC30 taps leaking when the bike has been sitting causing flooding and eventually engine damage(from fuel filling up the sump), don't know if that would be an issue with the 750 tap though.

#73

So... I have been hunting for a decent gauge set that will work well with most of the factory wiring and isn't ginormous since I'll be running this with no fairings. It seems I have two choices:

The Trail Tech Vapor, which I'm not really a fan of...

[image: 7011828855_e1db85292b.jpg]

Or there's the Koso gauges which I like but are pricey...

[image: 7011828611_7cb28515b7.jpg]

So, I am thinking of ripping apart one of the gauge sets I currently have from the VFR and reorganizing them into a nice compact little set that will definitely work with the factory wiring.

[image: 6865744490_260eccec24.jpg]

Here's the layout I think I'm going to go with.

[image: 7011811517_cc325cd9cd.jpg]

it's much more compact that the stock gauges.

[image: 7011810949_43f430c81e.jpg]

I do think I will make a much smaller version for the fuel and temp gauge as well and figure out a nice spot to mount them as well.

Has anyone done anything like this on here before? I did a search and went through about 8 pages of search results with no luck.

NakedViffer I've been running gravity feed with the factory unmodified tank for some time. Fuel pump on these bikes is useless, just one more thing to fail.

Thats promising.. might have to take u up on it....

Remember my spanner telling me the pump was just for safety shut off in the event of something happening, that was some years ago?

But then remember a thread here was mentioning fuel pressure and scavenging fuel from tank when low?? Handy also?

Have similar questions about extreme braking on track etc? Will be right back on that power and want good fuel availability?

Bike in rebuild mode now with a new rear ally sub frame .. the rear is not plumbed in yet as im to finish a carbon nose fit.

Dont want to change pump and COPs at same time... Unless am gonna stick me neck out...

Na just decided, pump first test- with normal coils

COPs maybe after..they are here and ready once basics are plumb.

NakedViffer I've been running gravity feed with the factory unmodified tank for some time. Fuel pump on these bikes is useless, just one more thing to fail.

Thats promising.. might have to take u up on it....

Remember my spanner telling me the pump was just for safety shut off in the event of something happening, that was some years ago?

But then remember a thread here was mentioning fuel pressure and scavenging fuel from tank when low?? Handy also?

Have similar questions about extreme braking on track etc? Will be right back on that power and want good fuel availability?

You really need to do up a thread on your bike KGS, one of my favorites on here.

I've not had it on a track, but when I ride, I really ride. Compared to a lot of people, I torture by bike, and I live in the mountanis so its been through tons of hard cornering, braking, wheelies, full throttle launches. I've never had it act like it was starving for fuel except on occasion when I run it dry. And when its out, thers nothing left in the tank. The pressure differential inside the carb can act like a siphon and keep drawing fuel as long as theres no restriction on the flow.

I recently worked on a 67 Buick special, and it had been running and driving for years, until the fuel filter got changed, couldn't figure out why it wouldn't run.. Well it turned out someone bypassed the mechanical fuel pump on the block and had it coming straight from the tank. Which is onviously lower than the carb atop the v8. It was just apparently full in the line when it got hooked up and kept pulling it up as needed. But once the line was empty the carb vacuum wasn't strong enough to pull it back out from the tank.

So even though the petcock is close to carb level, it gets a great feed. One thing probably worth mentioning is that I don't run a fuel filter, and that helps it flow freely. I've heard of some guys running with no pump and a filter, but theres no telling how hard they were pushed.

Has anyone done anything like this on here before? I did a search and went through about 8 pages of search results with no luck.

a few times.

first here with a 3rd gen, using just carbon sheet and a few led's. Was not the best, but ran well and was cheap.

Then was the 4th gen which was the best look. Using CBR fireblade clocks.

[image: post-5025-0-97475200-1332628725.jpg]

Have now trimmed the speedo similar to the HRC RC30 manual, which gives a better factory finish.

not sure what to do about idiot lights yet....will see. There are actually three round spaces i could drill into and mount a light in each. They mount the foam. Visible in pic there.

Could only really use a green neutral, a red oil pressure and a reserve fuel lamp.

cheers,

will see how my net connections go and how soon i can find time to put bike 2gether...

am 2 busy robbing everyone elses ideas at the moment.. haha

#79

You and me both! Why do you think I want you to post up a thread on your bike? ;)

#80

Just fyi, i looked at my buddies magna and the cable mount bolts to the block right where our frame bolts to the engine. With a little engineering one could just make one to go on the outside of our frame and be just fine.

Bump for updates on your build!

Bump for updates on your build!

Haven't done much on the VFR lately. The gasket kit I ordered came and was marked for the VFR750F but it was just wrong... The gaskets were for some V-four but not the VFR... A least not a 4th gen.

So, now I need to find a gasket set that does fit and see if I have money to cover it while I am waiting for the refund to process back to my PayPal account.

Sorry there isn't more cool stuff to talk about.

#85

I have a lovely set of 1998 CBR900RR gauges for sale that will work nicely on your bike. They're just like the set that MrMatt put on his bike.

PM me if interested.

#86

a 98 should also be a transmission driven speedo pickup instead of countershaft sprocket pickup, correct?

it's much more compact that the stock gauges.

Can the O.P. please post a picture of the area right behind the radiator on his bike? I'd like to see what kind of room there is behind that between the head and valve cover.

Mine is completely disassembled right now... maybe somebody else? IIRC there isn't much space between the fan and cylinder cover.

#94

one thing you should note is that i have removed a large plastic shroud cover thing between the air box and radiator. this is a third gen, but i can't imagine that there would be any real differences from the forth gen.

Think this will fit?

#96

make it fit, have ordered 4 gsxr1000 k8 COPs. Will see if they work in a day or 2.....

#97

Eddy... What are those COPs off of?

#98

Hayabusa. Reference the "4th gen cop" thread in modifications.

gotcha... I picked these up. They are from a GSXR 600/750. I haven't tried them in the vfr motor yet, so we shall see how they fit.

[image: 6872470692_3f7dc1c985.jpg]

#100

They will fit just like mine do in that picture.

#101
I could probably do something with some RC stuff. Those motors weigh nothing, are pretty skinny, and can spin plenty fast. Just need a way to limit current to a set point, and hook it into the existing fan switch.

Magna radiator is about the same size as the vfr.  They might even be the same part.

Looks smaller to me... i have no hands on experience, however.

#103
On the subject of rc motors lol i thought about a few small ducted fans to blow through the radiator, perhaps use an intake duct for the fan jntake
#104
Unfortunately it's not all that easy. I don't think that short of a duct would justify having a bunch of small fans.
#105
Two WeMoTec microfans would probably flow just as much air as the stock fan. Probably more.
#106

Maybe the magna has a smaller fan, plus the shround can be cut down a little if the object is to just make the coil packs fit. That magna radiator defiantly looks smaller and would be a better fit for a steet fighter. The stock rad is too big.

Disagree on those being a possible solution. There are a bunch of big issues with this. One is that you will need to keep the fan blades as close to the radiator as possible to ensure air is being sucked through the radiator and not just around the side. The other is that an RC brushless motor requires a 3-phase power source normally provided by the ESC. I can get a motor and prop that would be a bit thicker than an inch I think. Mounting wouldn't be too hard either. Might be able to get a programmable ESC and set it so when it receives power to turn on to a set level, which will prevent the RC motor from drawing too many amps and frying something.

The EDF you listed will be much thicker, and being ducted, will only pull air from a small area. There are no off the shelf EDFs that are thin that I know of.

A better solution would be to find a DC motor and eliminate the ESC.

#109

Im talking about blowing the fans onto the radiator not drawing through it. And id probably just use a small dc brushed motor and not worry about an outrunner brushless.

#111

I think if you look on service honda they give a pretty good description of what is in kit A and kit B.

#112

Yeah... I guess I'll find out pretty soon as it should be showing up at my house early next week.

Still collecting parts and tools to finish this project. I am planning to do my own powdercoating to save money and to learn something new. Here's what I've added to the garage to make this project a reality.

My oven, Craigslist for $60... I added casters to make it easier to move.

[image: 7230882336_a13056a25d.jpg]

The new cord for the oven, so I can plug it in the laundry room... $65. Strikes me funny that it cost me more to plug the oven in than I paid for the oven.

[image: 7230883994_53c944bc96.jpg]

Sandblasting cabinet borrowed from a friend, it actually belongs to his wife... Go figure

[image: 7230885074_7433d056cf.jpg]

Powder coating gun... For only $35 (regularly $175) I thought it was worth a try.

[image: 7230886364_3d603ae784.jpg]

I've got a pound of 20% gloss (satin) black powder... I'm not sure how far that will go.

http://www.powderbuythepound.com/BLACK_20-_GLOSS.html

I'm a little nervous about my compressor, it's pretty small... Not sure it will keep up on the blaster. But we will have to see. I plan to start coating some small parts this week, then I'll fashion an extension for the oven to do the wheels and frame. I'm pumped!

#114

Make sure you have a good moisture filter for the blaster. It won't take much moisture to dampen the media enough to start clogging up the works.

Thanks Kel! I have to say your VF project was definitely an inspiration for my powder coating attempt.

#117

I have officially started powder coating parts!

All parts were blasted with 80 grit glass beads and wiped down with acetone. The parts with paint were stripped with Aircraft stripper, then blasted. The glass beads are pretty slow to remove paint.

The obligatory before pic:

[image: 7301836232_bcf2991595.jpg]

After... I masked off the splined hole for the clutch lever:

[image: 7301836932_1e939f1742.jpg]

I thought about masking the machined areas on the clip ons, but decided not to. In the end they still fit on the fork uppers just fine. I will have to run a tap through the threads to clean them out, but the powder didn't get too deep.

[image: 7301838294_ff495b81d3.jpg]

Here's the brake side reassembled:

[image: 7301835766_3fa5c368e1.jpg]

I'm feeling pretty happy with how they're turning out with my home powder coating setup! I'm using a 20% gloss black that is UV resistant from www.powderbuythepound.com. There is almost a slight metallic look to it.

I thought about doing a detailed how-to write up for someone else wanting to do the same, but a lot of the info is on here already. If anyone is interested, let me know and i'll throw down a write up on what I did.

#118

Got the top triple done as well...

[image: 7307792684_2382a3177d.jpg]

Been thinking about the engine... Anyone know if I can coat the camshaft covers, clutch cover and stator cover?

I think the swing arm will fit in my oven just fine.

I've gotta figure out if and how I can do the frame.

#119

Yeah, you can certainly do the valve covers and other engine covers. Just clean and mask them well.

My valve covers are powdercoated, plus I painted the clutch cover, stator cover, countershaft cover, and clutch master cylinder.

Alright, now I'm officially on board with the DIY powder coating thing and have to start sourcing the necessary equipment and appliances. I have you to blame for making those parts look so good!

#121

If you're on a budget and want an inexpensive gun tat gets the job done... The craftsman gun from amazon is a really great deal at $35. It's completely self contained, no compressor needed.

looking good! PC monster has been created.

No doubt! I found myself wandering the garage looking for what else I could powder coat.

I've also been looking at this product LIQUID 2 POWDER that you mix with your powder, spray onto any material (not just metal) and then bake like powder... I wonder if it will work with fiberglass. I'd love to powder coat my tail fairing and bellypan too!
