Hello, I have a 17 crf450r that started suffering a bad bogging problem after installing a vertex hi-compression piston. I have put a new fuel filter in and put the optional spark plug in and still boggs. I run 100 oct avgas. Some have suggested race fuel and someone else said I need a new cam. Anybody have any experience with this situation? Appreciate any help I can get.
