I just rebuilt the engine in my kx 250 and the compression is
215 lbs. I was wondering would it be better to run pump gas or race gas. The engine is stock except for having the head milled, and a wiseco piston. It has a fmf gold series pipe and power core silencer and if you could tell me what jetting specs would you recommend. Thanks for your help.
