Hey Shane, welcome to the forums. it could be a number of things, bad gas, gas mix is wrong, power reed mught be broke, you could have low compression from a hole in the piston, although it would be pretty hard to start to begin with. Perhaps the coil is having issues. Its kind of hard to diagnose on a forum, but if you can provide more informaton. Is it a water cooled bike, what year is it. Throw up a picture if you can and give is a blow by blow on what exactly is happening.

 

Welcome to KF

It does sound like you may be overheating at the moment. Just a thought to check out your stat and pump impeller. Let us know on the progress.
