I race desert. This weekend I got into a slippery section and backed off the throttle enough to hook up the rear tire again and when I got back on the throttle it went poof. I couldn't get it started, I tried hot start with no throttle I tried hot start with full throttle, and both without hot start. It finally started but cost me the race. Is this a jetting issue or just something I have to live with. I realize the real problem is the accellerator pump, but what now?
