Ok so my bike stalled on me a lil while back it would get tight as if it was locked up and it would free up sometimes.. and its time for repair, but i took the valve cover off and flywheel plug to make sure it was in time before i tear it down and it looks like i am one tooth off?? auto decomp. is working fine no signs of wear or anything out of ordanary...?? Bike was running fine before this happended all it did was stall on me and i took a break for a sec and went to kick it and it was hard like it was locking up....then got it in the garge and it kicked over fine for a few...then tight spot!? Another problems is i bought bike used so i dunno how to tell if i got stock cams or its a 450 cam? Anyhelp would be awesome!!!!!!
