My bike has no compression right now. When you first kick it, it will have some compression then it goes to nothing at all. There is all kinds of air coming out of the breather hose and out the exhaust pipe. The bike has only got 14 hours on it. It did this one time before but after the 2nd kick it started working fine and run good all day. Has been running good until it sit for about 3 weeks. I'm really leaning toward the valves been stuck open. If thats what it is, what would be the best way to fix the problem? I'm thinking about letting yamaha know about it and go from there. I have talked to another guy and he said his done the exact same thing.
