I have all the parts to complete the top end on my 83 KDX250, including the new Wiseco piston kit, needle bearing, gasket set and kick start oil seal (took the engine out and the engine cover!!). My question is, since I'm putting in a new piston and piston rings, do I need to mess with the jetting at all? I assume that the jetting is stock. I've never had carb or acceleration problems if that matters and of course the piston is stock bore.
THanks
