Ive got to do a connecting rod and crank bearings this winter on the old xr she has been knocking pretty bad all year. If I tear it down and see that it needs a cam(likely) what are some recommendations for a cam. I do mostly trail(2,3rd gear) and some duel sport riding. I'm really happy with the power I have now. The beast has been punched out 1st over and I'm running a wiseco high compression piston with stock exhaust. The dual carbs are running great and she starts on the second or third kick year round. If I put a a bit more wild cam(stage1) will I have to rejet? thoughts?
