Before I buy

[4stroker]

if you advance the timing 3-4 degrees the engine will have more bottom and mid range power, while sacrificing a little top end.

 

buy the timing plate and have a play with it. its not hard and you'll learn something. its only like $35 us on ebay.

 

112 psi sounds slightly low to me, how many hours do you think the bike has? have you had it since new?

 

if i were you i would whack the noss head with 20cc domes on, comp test it again, and then keep an eye on the compression every couple of weeks, when it starts to go down, i would go with the first or second oversize wisecos.

i bought the bike from queensland and the guy rekons he only rode a couple of times.. and i have only gone through 1 tank so i dont

 

know.. but when i get the noss head i willl do the test again.. and how much comp should i expect with the noss head on?

 

also how strong are the stock cranks?

 

thanks

the stock cranks are better quality than the generic aftermarket ones such as hot rods.

 

you should get at least 3 top ends out of a crank before you have to worry about it.
