Could this also cause my bike to stall while riding? I've been having a problem with my 2002 Harley Sportster 883 where at first it was popping and coughing through the carb then started to back fire then would shut off after. I would wait for a minute or less and all power would come back on. So i bought a new battery for it also ended up buying circuit breaker as well and a new ign. Module and cleaned out my carb. I turned it on ran it for about 30 mins it ran great no more back fire coughing or anything. Then I turned it off let it cool down for about 20 mins and drove it again. This time as I was driving on the freeway it stalled again. But no backfire or cough or anything. Any idea what it could be ?I'm waiting for my new ignition coil but at this point I'm pulling my hair!

The head temps sensor is nothing more than a temp variable resistor. If the temp reading chances quickly, it's most likely a looks connection somewhere. It could be inside the sensor or inside the ECU but is more than likely a connector. Could be the one on the head or the one at the ECU.. Most common is the head. When doing reliability calculations for electronic equipment, a big factor that is included is the number of connectors in the system. Simply RnRing the connectors may have cured the issue.
