Second time this happened to mySport in high heat after a short run up the road (thirty minutes), and a very short stop->restart (minutes) attempt, then failure to run. Like a "vapor lock." First time, it cleared out suddenly after maybe twenty->thirty minutes. Like it never happened. This time, (High heat: 95ºF/ higher "heat index"), I got maybe 200 yards and the Sport would not recover. Tried cycling the fuel pump (a dozen+ times). Opened the tank cap several times. Chatted with several concerned locals stopping to check on my plight. After an hour pinned between the edge of the road and the guard rail, I thought it would restart after "cooling off." Fanned the petcock/fuel line/fuel pump over the left cylinder/head. No joy. Started to fret over the Timing Sensor. The ECU. Swapped in a fresh #5 (fuel/ignition) relay . . . Figured I fouled the plugs with so many restart attempts an decided to swap in new plugs (always carry new plugs!) thinking the bad plugs would be wet soaked from so many restart attempts. After an hour cool down and fresh plugs, started up and rode home . . . Yeah, they are "plugs", just not *spark*-plugs! Right as I was celebrating turning 134,000 miles . . .

Recently acquired 2001 V11 Sport. Just looking her over and found that the plugs look a bit sooty. There is a Power Commander III fitted. I was thinking of taking the PC off as I'd rather have the bike stock. I assume the stock ecu will just work without the PC inline and won't need re-programming? I am thinking that it's over fueling and hence the sooty plugs. Idle is a little uneven too.
