Hey waz up?? i need some help with my raptor:: i have a raptor 660 2005 and i have a hmf full exhaust system,jet kit and a uni filter... im thinking on put a new piston with more compression cuz i read that the raptor has a very low compression 9.2:1 and i would like to put in at least a 11:1....
so somebody told me that i could buy a 686cc piston and use my stock sleeve, just bore it up, and my question is: would u recomend me do that? or should i stay in 660cc just with high compression?
