Hey im gonna be getting a High compression piston (wiseco) and i want to know what the highest compresion ratio i can have without running race gas, I have recently put a cam and new rockers in, I am planning on using the stock bore.

 

11:1

 

Thanks, anymore suggestions?>

 

I have some questions.How big of a difference did the pipe and cam make.I am buying the 300ex from ym dad and plan to add these before I go big bore.

 

Oh i can tell a HUGE difference in top end!! it is FAST!!! just make sure if you get the cam to make SURE you get hardened rockers! thats a MUST!
if you have any other ??? about installing or anything e-mail me

 

also get a good pipe and a jet kit! that helps ALOT

 

Thanks for the advice.THe mods I have planned for the motor are.TC suppertrapp shorty pipe,K&n filter,Ported and polished head,bore .040 over,400ex carb,bigger valves,TC cam and valve springs,Hardfaced rockers,Hinson clutch basket,barnett clutch,and an oil cooler.

For the suspension and handling works pro series fronts,works duracross rear,lonestar axle,fastline brake lines,Ac full chassis skid,Ac swingarm skid,Ac pro pegs,6 ply razr's all way around on douglas wheels,and other things.


As you can tell it will be set up for xc and will not get done over night could be a couple of YEARS.First i got to buy it.

 

thats gonna be a sweet quad!

 

I put a 10.5:1 in mine.....i called up TC racing and told him i wanted to keep the stock bore and this is the set-up he told me to use (minus his racing pipe...too expensive and loud!) i really like this set-up....i can keep up with just about anything in the woods.....cr125's included! about the hardened rockers Tom said i wouldnt need them and i havent had a single problem out of it yet.
