More power

If you want to beat an R6 and not wrench, buy an R1. The SP models are plenty quick. We had a gal turn up on one at one of our meets and get timed at 188mph.

You can hot up your KZ, but it means going back to wrenching, which is why you sold the Harley!:laugh:

Bore and stroke:

78 KZ1000 - 70.0 X 66.0 mm

07 Yamaha R6 - 67.0 x 42.5mm

Notice the difference in stroke?

Piston speed is the limiting factor, the R6 has a shorter stroke (lower piston speed), so it can turn higher rpm.

The following maximum piston speeds are from the book, Performance Tuning in
Theory and Practice, by A.G.Bell.

Stock Motor - 3,500 fpm (cast crank, stock rods and cast
piston)
Heavy Duty Motor - 4,000 fpm (forged crank, peened rods w/ good
bolts, forged piston)
Drag Racing Motor - 5,000 fpm (forged crank, alum rods, lighweight
pistons, etc.)

Engines with long strokes have lower redlines than those with short strokes because long strokes cause higher piston speeds. Improved piston alloys, piston skirts coated with low friction materials, better oils, better control of piston to cylinder clearances, and shorter engine strokes have all allowed engines to run at higher rpm.

piece of cake!:Panything using afterarket sleeves is gonna require clearancing cases<br><br>Post edited by: PLUMMEN, at: 2007/07/12 14:54

not to put ur friend to shame. but the new gsxr1000's run 9's out the boxs.. i know vic from exoticycle was running low 9's with just a full exhaust and airfilter on stock wheel base


none the less i know a guy with a dragbike turbo gpz and well alot of the street 1000's well eat him up...

iv seen alot of old school bikes run at the track(wheelie bar bikes) and iv seen/rode alot of newer bikes(busa's, 600s,750s,1000s) turbo, sparyed or both.. i really dont think ur seeing how much money its takes..

i with the guy that said swap over the gsxr1000 motor...

show me a stock gsxr1000 running 9s out of the box,cuz it aint happening around here!! maybe a skunk works bike thats been breathed on with pee wee gleason riding it!:woohoo: around here a lowered and stretched busa will run 9s with a little tweaking,zx-14s with around $3500.00 worth of extras which brings you up to around $18,000.00 will break into high 8s with a pro rider which aint really impressive to me!

im suprised there hasnt been pics of an 1197 turbo pop up yet:P coughwiremancough:whistle:
if all else fails, just put one of these in your bike

call exoticycle. vic ran low-mid 9's and a gsxr1000 with just a full exhaust and air filter.. i know i helped to put on the pipe and rebuild the frontend..

but again he only weight's like 120lbs and is a prostar rider..(mikey slow was there test riding johnnys turbo/sparyed 1000)

i dont care if u dont believe me. iv seen it with my own eyes and i hold the slips in my hand..
seen it more than once since the kid wouldnt stop riding it down the track.. hahah..


not alot of ppl can ride that good.. like i said i pulled 11.8s on a old ass cbr 600 f2.. no one believes me but the slip dosnt lie...

Put a turbo on a 1200 and it will run mid nines like mine. Put a bigblock with cams and carbs, etc. and make believers out of some of those new rocket bikes. My turbo blows ZX12's all the time...even a few busa's. A LOT is in the riders, but I have beaten quite a few 600's with my other Z with no porting or cams yet, so it can be done. A good rider on a 600 can get mid tens and a Z can do that without too much trouble but it will cost. As they say "speed costs...how fast do you want to go?"

I am know more confused than ever. I just got into the old KZ's. I haven't purchased one yet, but I am looking for KZ1000 or Z1R. And I wanted to build one that looked good with a 240 rear tire, new inverted forks and modern brakes. I was looking at building a 1200 with ported heads or ported GPZ heads, custom exhaust, maybe supercharger or turbo. But I wanted to be able to ride on the street. And kick some asses from stop light to light(short distances). What do you guys think.

And around here we have run in the low 9's on liter size bikes with only pipes and power commanders(the usual). And now with the new 14's they are reaching the 8's. But we mostly run 1/8 strips. These tracks are closer and the experienced riders run around 6.3 and lower and I now sponsor two riders. One of them is my brother on a new 14 running 5.9 on his second and last pass after cracking the oil pan. And another rider on a Busa running 5.7 with nitrous.
