Hello all. Just got back from a great trip to northern MI (Gaylord area). Put on about 250 miles. Sled ran great except for fouling two plugs(BR9EYA's). This happened on two seperate occations. Once at about 125 miles into a days trip with temps at about 30 degrees, the other was after a cold start in the morning. Both times it was the PTO side cylinder. The plug was very carboned up and wet with fuel. Once a new plug was installed everything is fine. Since this is only happening to one cylinder I think I can rule out jetting. I checked my mains after a long full throttle run and ALL plugs were just about perfect. I think the problem with this cylinder occurs at idle or at a part throttle cruise. Any advise/suggustions would be appreciated. The sled has ~2,000 miles on it.
Thanks,
Rob H
