my check engine light has come on three times in the last few days. Bike seems to be running just a little bit rough—a very slight surging when running at a constant speed. If I stop and wait a minute then restart it has twice rushed up to a 3500 rpm idle for about 10 seconds before settling in to a regular idle. Not sure where to begin troubleshooting. I have Todd’s ECU flash tool do I remember right that it can also be used for diag?
