Big Bore Kit

Does anyone know of anybody getting the big bore kit for the sixth gen? I have heard of it on the fifth gen. see below

http://www.vfrdiscus...showtopic=33919

To me,,, I'd just get a 1000RR and be done, jackin HP costs more bux than buyin a turn key operation in bikes...

example,,,, freshen up big bock chevy in dragster,,,,, bore, stroke, heads then to flow more air,,,, oh wait cam then,,,,, etc,,,,, :rolleyes: :rolleyes: 10k later.......

Hmmm... this is true, I guess you would have lengthen the duration of the cams unless it could be compensated some other way, or have a custom ECU to take care of the fuel metering, because I don't think the PCIII could compensate that much. I am going to have to take a look at how the fifth gens do it.

if your looking for more power and are going to take the motor apart take the heads off. do a port and polish on them i'm sure some cfm could be freed up. i did it to a bunch of kawi's and got good results. even if you just clean up the castings you should see some sort of gain

Yeah, mill the heads, clean up the ports, bigger cams, bore it, stroke it, start indexing plugs, get the comp ratio up there, start using 9.00 a gallon race gas,,,,,, hell, put it on alcohol, and give it a 100hp shot a NOS while your at it :rolleyes: :rolleyes:



Or, leave it alone and buy a race bike,, that way you can still ride anytime you want,,, not after you get done working on it,,,,again, trust me, don't race a daily driver

Just my .01,,,, used to be my .02 worth but the economy has left me a little short :laugh:

Sounds like a great excuse to have another bike!

I'm curious too??? and please don't just tell people they can't do something or shouldn't... If you can't answer the question or offer help...why post???

If anyone does know of a big bore kit please let us know!

Haha, guess you don't know that we ride together, I was givin him a little bit a crap.

But I will stand behind my, if you want to RACE, dedicate a bike/car/boat, skateboard,,, whatever to RACING, not a daily driver, which is what I believe is his intentions for his bike.

Now if his intentions are to RACE it, I can't wait to help him spend some money :biggrin: Prolly a Toro Charger would be the most bang for the buck, like I SAID in my earlier post, big bore means alot of other things to consider, cams, valve clearance, milling heads for comp ratio's etc,,,,, by thinking that you can just put a bigger piston in a bike and go faster is,, well, pretty foolish.

The NOS, race gas, and alcohol was sarcastic ;)

FYI, I have beeen racing a long time, spent alot of money going fast, love every minute of it. Hang around, you'll figure out when I'm busting someones balls, I do it quite a bit :rolleyes:

EXACTLY

I think that I may just have to wait for that toro1 supercharger. I was just kinda wondering if it had been done, but I think the supercharger would give me more driveability and longevity.

Thanks for the explanation...I didn't realize you two were buds. I get sensitive when I'm searching and have to read through a bunch of posts from people not addressing the OP question. I'm just looking for a way to keep my bike and not get a New Concours. I had a '91 and loved it just a little too big for a dd. Now with the VFR for the last 5 years and I really like it...just wish I didn't get left by 600's every time we roll on the throttle. Looking for just a little more power to scare myself with. Yeah... you can spend money on a PCIII and an exhaust but for the $1k you're really not going to feel much.

I do hope the ToroCharger finally comes out for the 6th gen...

Later,

jim

You're gettin left behind the 600's?? Mine is pretty much right with them all the time, that is until 140 or so, then the top end for them is better, but anywhere up to that pretty damn close,, depends who had the right rpm's at the moment to who's gonna pull the lead.

Ever thought about dropping a tooth on the front sprocket??? cheap and easy power :biggrin:



Sorry bout the thread jack :rolleyes: seems I do it as much as bein a smart azz

I have never had a problem keeping up with the 600's until 140's like cruzinaz said and I have passed a ZX-14 and Busa' with the hard bags on (in a turn, they were none too happy about it either.) When I think about getting a new bike, I also have to remind myself that I am not Rossi or Hayden and I have all the power I need right here, I just need to become better at using it.

I have no problem finding enough power with my wrist to scare my azz half to death every time I ride my VFR. Of course I have an unfair advantage with the hi-po Nuwheel polished pimp-o-licious rimz treatment that's an easy 15 hp increase over stock. The Scorpion cans are probably another 40 hp, not to mention the mohawk that's good for another 10 hp. Pfft...Torocharger, smorocharger ! !
