[QUOTE="RossKean, post: 1419434, member: 19880"] Any stored codes? (Specifically code 14) Ambient temperatures hot or cold? Was it damp or raining at the time? Any electrical gremlins such as odd behavior of dash indicators, high beam light coming on, turn signal indicators, horn not working, no access to glove box etc? (spider symptoms) Have you had the Gen II ignition switch recall done? Have you checked the TPS via the Diag. function? Not always a good indicator because the environment of a cold bike in your garage is not the same as a hot bike with bumps and vibrations on the highway. MIGHT be fuel but this isn't a common issue. Try a good dose of Yamaha Ring Free. MIGHT be TPS but also not common for Gen II - more on Gen III+. MIGHT be a bad connection at a spark plug or a bad coil. MIGHT be connections at ECU MIGHT be fuel pump or dirty fuel injector issues MIGHT be a rodent nest in your air filter Lots of possibilities. Check out the obvious stuff and if it happens more frequently or you begin to see a pattern, you will have to dive into it. Good luck! [/QUOTE]
