I raced up in Nevada last weekend, and my god damn bike wouldn't start in the morning, yet it started the day before 2nd kick. It was really cold (27 degrees) and the elevation was 4400 ft. I have taken it to elevations that high before and never had a problem. Anyways, we kicked the shit out of it desperately trying to start it before my minute took off. Finally we bump started it behind the truck. Once it fired there was some smoke out the pipe, but it quickly went away. The bike ran great the rest of the day/race. No complaints what-so-ever. I just fired it up today in the garage. No problems. Runs like champ. Now I'm super nervous this motor is going to fail on me. The only thing I could think of is a valve tightened up; however, if that was the case, wouldn't starting it in my garage just a minute ago be a pain in the butt as well? Something doesn't add up.
