what are your thoughts on using 91-94 octane gas on this low comp motor.. at the track its all i feed my 2007 ZX6R.. but when i have the GPZ there..

mine has stock comp.. which is what.. 9:1?

any advantage to using the faster burning gas, like 87 or 89 octane?


I've done several research papers on octane rating. Do yourself and your wallet a favor and run 87-89 octane. You're not going to have to worry about detonation with a 9:1 motor. With higher octane you're more likely going to make less power than with 87-89 since the flame front might not reach every part of gasoline before the exhaust valve starts opening.

The higher octane is fine in the ZX6 since they run 11:1 or higher CR.

I got the bike on the national dyno.. i think the dyno (pro) reads a bit low for obvious reasons.. i was able to get the bike to 70.6hp with the airbox, 117.5 mains and no air filter. i will probably go down to 115s and put the air filter back in.

bike needs a rounder front tire and 1 or 2 teeth up on the back sprocket..

the exhaust worked great i put a baffle out of a yosh rs-3 inside and packed it pretty good with old fiberglass.

I beat a few SVs :)
