After a few month layoff sunday we went a rode our dirt bikes. Yesterday I cleaned my bike, changed my oil, cleaned the air filter, adjusted the chain, installed the enduro engineering clutch lever, and felt pretty good about what I had done. I decided to crank the bike to adjust the clutch lever free play. So it fired right up ran for about 3 seconds and died. But the way it sounded didn't sound good at all. It was a real abrupt sound. There was also a little puff of smoke that came from the right side of the bike but couldn't tell where it came from. I couldn't sleep last night thinking that my bike may need a rebuild. I haven't ridden it but maybe 5-6 times! Any advise is greatly appreciated. Thanks.
