I fear shutting my bike off when I know I'll need to start it within a half hour, cause it normally won't start. If it does make it as far as turning over, I'll rev it in hopes of it not shutting off and a couple seconds later it dies as I'm reving it. I've played with the idle screw and that seems fine. Could it be my fuel screw is too far out? I'm running 55/158 .024", Twin-Air, no snorkel, about 2 1/4 turns out. Could it be a bad spark plug? If I let it sit for about 5-10 minutes it starts. Thanks guys.
