Hey. Check out this month's issue of Performance Bikes, from the UK. They have a 3 page section on tech tips for the ZX6R.

They mention a 654cc big bore for the ZX6R (599cc) '00-02 engine. Does anyone have this? How much coin we talking? How much power? Re-jet issues/settings?

JE pistons it said, hmmmmmmm.

The price should be around 1000.00 CDN or so....reboring, easy...but getting the cylinders re-nickel plated will be a chore....when talking with Canada Kawasaki's guy he said is was hard to find a good company that could do a job that would last...compared to Japan spec.

If not the the kit might come with their own cylinders that are ready to go....just bore out the block and slide in the new ones....rater pricy though.....

Then the rest of the job costs and such......I'm thinkin' head work is cheaper and you get better life out of the motor too....For those prices you could get a spare head and do the work to it alone...then just drop it in when you are ready....either restrict the ports, like "Mototune" suggests or go the traditional way with enlarging the ports.......I'm going to try the restricting way first then if that doesn't get the results I want then the extra material can be removed and more taken away........win/win.

Sorry more to add....

The main reason I suggest this is cause I read an article quite a few years ago when they took a stock GS1100 and did extensive head work to it and put it up against a ZX11... the GS took the ZX in the quarter mile by 1-2 bike lengths.....mmmmmm....makes you think!

Old ass GS style takes out new generation ZX......

The GS had the carbs done(jetted) and an aftermarket exhaust too.....

Remember, the key is getting the gases in and out as quicky as possible this is where you get efficient power....big bores work cause they cause a stronger vacuum to pull the gases in and push them back out with their larger surface area.

There's a company in Woodstock Ontario called Wiseco pistons, I believe they're on Keyes Drive. Might be worth looking 'em up and giving 'em a call... never know... I know they set up an old boss of mine who did up Polaris engines for high-speed radar run races he was into way up North...

Hey!

Post the dyno plots on the head porting/velocity results!

Cool, thanks. http://www.wiseco.com/PDFcatalogs/2002_CB_screen_kawaski.pdf
