A friend a few states north of me sent a note saying his check engine came on after an oil / filter change and won't go off. After changing the oil it started right up oil light turned off as it should but then the check engine light came and the rear cylinder started missing. He said it was running fine before the oil change.
I suggested that he make sure the spark plug wire wasn't loose on the plug and it wasn't loose on the coil. I also mentioned checking the sensor connector below the head on the forward part of the rear cylinder. And to check all the electrical connectors under the left front of the air box.
I would appreciate other ideas on this symptom? All help, suggestions, or otherwise is appreciated. Have a great day folks and ride 'em safely. Ken krb1945
