    Check engine light comes on and goes off without rhyme or reason. Sometimes it will stay on for days, sometimes it randomly flashes off and on while riding, and sometimes it clears itself to come back a few days later.

    This has been happening for a month and I've attempted checking for error codes with tuneecm 6 times. There is never a stored code. Bike seems to run fine with light on or off. I updated factory tune to the appropriate TuneECU variant and the light stayed off for a few days, only to come back again.

    Anyone run into this before or have any ideas for what I can look for?

    I remember Click and Clack, the Tappet Brothers of NPR fame had a solution for cases like that:

    My Rocket throws a Blue light when it gets hot :thumbsdown:. This bike does not like Houston summer traffic. Anyone know what this mean?

    Blue light means the fan is on.. You may hear the fan cut in at the same time the light comes on.
