Author Message   Erics1 Posted on Thursday, December 10, 2020 - 04:36 pm:        My 'new' 2006 XB12Ss (19K miles, Drummer exhaust) ran fine my first few rides, totaling well over 100 miles. Then in the middle of a ride it began backfiring seriously, bogging and even stalling. Since then it's been running OK, if not as well as before, but the engine malfunction light comes on after several miles. I feel a little stumble when it comes on, but then the bike continues to run OK. ECMSpy is showing 13 (with the Drummer exhaust there is no 02 sensor?) and 15 (I can't see any values in the live data screen when the bike is running) . Another inmate (thanks, AKBuell) said that his similar problem had been a faulty Engine Temp Sensor, but I believe 15 is the Air Intake sensor? Suggestions?
