The second event, even after letting the engine cool down completely, the engine would only idle. However, after about 8 hours, the engine would rev again for only about 5 minutes, and not get hot at all, and abruptly drop into idle. Wait another 8 hours, and it will run for about 5-10 minutes, and then drop back into idle.
Some simple maintenance I’ve done:
– Cleaned the air filter, and the intake between the seats
– Changed the oil
– Checked the plug, some minor fouling, but not too bad
– Load tested the battery (stretching if the problem was power not getting to the EFI)
Anyone seen this kind of behavior before and know the remedy?
