So I was at the track today and out of nowhere my bike would randomly sputter on decel or occassionally when cracking the throttle. It was about the same as it does before it runs out of gas. It did it maybe once every 2 or 3 laps with some being a mild hiccup and others where the bike would hardly accelerate. Then it stopped for a while. What ended my day was when it finally stalled out getting on the track and would not fire after that. I am looking for any ideas before I actually get a chance on Monday to dig into it. At first I was thinking carb related cause opening the throttle in the air or landing from jumps semed to do it more often. I had noticed when it first started happening that the wire for the neutral sensor had gotten into the header and melted slightly. I was able to take a quick look at the bike after riding. I pulled the plug and it looked ok, although I plan on changing it before beginning the trouble shooting. The spark also looked good. We also checked the neutral sensor wire and found it seemed to be ok, just melted the jacket a little. We did get it to start again in the shop but it would not stay running. I am planning on starting out with the plug, and when that doesn't solve it probably go through the carb (cleaning and check float level). Any other ideas or suggestions?
