Hey guys, I just bought an 03 yz450. It ran great, started first kick. I rode it around the block a couple times. Today I go to start it, and it won't start. Smoke came out of the exhaust. Now it won't turn over. I have rebuilt 2 strokes, so at least if have a little mechanical skill and a few basic tools.
