Right now my 85 lt250r has about 165 lbs of clyinder pressure, the Zilla has 195, i am looking for some more squeeze out of both of them without spending much. How much cylinder poressure is too much for both of these machines? im willing to run 102 octane, as I have access to it, so is it safe to shave the heads?

 

I am running close to 200lbs and everything has been fine.

 

I ran 215 on my 250r and never had a problem

 

are all u guys runnig race gas or what ?

 

I run C12

 

AH, i see
