[QUOTE="jimt_yz400, post: 157587, member: 21081"] Well......I'd like more off of the bottom and a healthier mid, I don't anymore on top since this is for off-road use only, enduros mostly and playing aroung. My thinking was that the higher compression would give me more pull/torque off of the bottom w/o sacraficing the top too much. But, I'm concerned about the additional heat that this may create and the pblms with jetting (I'm sure that this could be rectified - the jetting). So, that's what I was looking for but I don't know if the HCP is the way to go. I've been able to acheive some good results with different exhaust systems but the pblm is that they are too loud, buy I'm working on that one. [/QUOTE]
