Sat I was riding my '02 gp1200 and it wasn't acting right. At high rpms it seemed like it was misfiring or 1 cylinder wasn't firing. As the day progressed it got worse, so I beached it and rode my polaris instead. Went to leave and the ski wouldn't even turn over. There is just a humming noise coming from the CDI. No warning lights or beeps. Any ideas would be helpful.
