Hoping someone can help Bike starts and runs great until about 2 laps when it gets up to temp for a while then it stalls out like its out of gas. I pulled the plug and get no spark when its warm if I wait about 15 min and it cools down and I kick I get great spark and the bike runs. Where should I start? I was told its probably the stator but I dont want to throw that much for one if its not the issue. Anyone have this issue or know of where to start?
