Its an 02. Some work would include bored .30 over, true weld crank, reeds, exhaust, 2-1 carb. Plugs are good. Top end was rebuilt recently, just did a compression test which turned out good. It just that one day it was running good, then all of a sudden it just died over. Everytime i go to kick it over, i feel a little compression, but i also feel a grind coming from the crank area. Any ideas still?
