Ill probaly be calling your josh. So far it looks like im going to be going with a sik 50s cam. Crower power said they cannot go over a .224 lift unless they biuld the motor. Sik can sell me a cam with a .265 lift. Josh, if you can beat that then ill get the cam from you.



Does any one happen to know what the lift is on the takewaga s-stage cam? Just wondering so ill know how much bigger of a cam im going to be putting in there.

ok a .265 with astock head it not gonna last long at all. yea it may be fast for a while but it just isnt goinf to last. i talked with josh and he says you shouldnt go over .260 with a stock head unless youo modify the head to make way for the extra valvetrain movement. .260 for a race motor w/stock head .245 for a motor w/stock head and will last a long time. and then if you wanna do a bunch of head and valvetrain work go for the .265+. josh knows his stuff and people in here can back that up with the peformance of their bikes after he has worked them.

Thanks PIMPIN, im not sure if im going to be going .265 anymore, i dont know if i want a pure race motor or not. My dad can do the mods to the head to make that big of a cam work fine. Ill probaly get a .245 from josh.

if your pops can modify the valve seats and get different lenght springs than i would go for the .260.



that would be a hot setup. or just do the light mod work and run the .245



no prob for the help. hes a busy guy with all his motor work hes been doing. im tryin to help him and those of you wanting to do this the right way. :D
