I was riding the other day and suddenly the roar from my pipes changed notes. One or more of the cylindars was no longer opperating. The problem was spuratic, sometimes for just a short distance and others for several miles. The first thing I did was check to make sure my fuel level was Ok and it was. The problem came and went over the corse of a 20-30 mile ride. I will be picking up a lazer thermometer so I can see which cylindars are dropping if it happens again. I will pull plugs tomorrow and check their condition. I have noticed a week response from the battery at start-up. Could a week battery possibly be efecting the spark consistancy and causing this response?
