Ok I tore thr bike down put new cylinder, gaskets, wiseco piston in. Problem is it seems like after 5 min of ride time it starts spitting and popping like a plug fouled, change plugs starts right up runs maybe 2 min same thing. I push it ot off the road into the shade (it's 91° still in Alabama at 5 pm) then start pushing bike home, but I got curious and decided to try and start it (it had been maybe 20-30 min since it shut off) 2 kicks starts right up, didn't change the plug this time either. Ride it about a min home by the time I got home and parked it started it again. Im jetted dmc exhaust, vforce 4 reeds, lid removed, k&n with outerwear, tors removed and taken out of harness also. Running amsoil dominator mixed 32:1. Anyone ever run into this? Any help is greatly
