I had to limp back to the dock today as it threw the P0325 then a couple others. It cut out yesterday after a moderate jump but restarted quickly and threw the IBR code C2 111. Reverse did not work until I got it home on the hose. It had just been filled up w/ ethanol free and running great. Topped it off this am w/ same fuel and added 3 oz. Lucas fuel treatment. It cut out soon after some slightly rough riding, restarted but with all the codes and limp mode. Like yesterday, IBR (reverse) would not operate until back home. All codes cleared in the driveway except P0325 knock sensor . I couldn't find any good info for this model / year.
Any help greatly appreciated as this is my vacation week.
