hi, i own a 2004 raptor 660 and i thought i saw an 11:1 piston for it a while back. now i cant seem to find 1. can anyone tell me were to get this part. and also i shouldnt have to change anything else exept higher octain fuel, should i? would i be right if i said the high compression (11:1 instead of 9.2:1) would rev a lot faster and create more torque? thanks a lot!

 

if you are going to do the piston you might as well do the cams and valve springs

 

I agree 100%

 

on rockymountainatv.com you should be able to find a 11:1 commpression piston thats were i got mine

 

i got the 04 rappy and I put the wiesco piston in it and I love it. Got it through rocky mountain too.
