Hi All. I have a 2002 1150RT with about 28,000 on it. Coming home from the rally two up and pulling a trailer we had gone about 10 miles one morning and were on a long steep uphill grade when the bike lost power without warning. We managed to make it to the rest area at the top of the hill where we pulled over. A quick check showed the bike was running on only the Left cylinder. Changing plugs around made no difference and there was a spark on the R. Anyway we limped back to the closest dealer. After having the bike for a few hours he advised me the exhaust valves were burnt to the point there was no compression on the Right. His diagnosis was that the valves on both heads would require extensive work. The mechanic attributed this to the bike running hot and ethanol in the gas. Is this a common problem on these bikes? is it normal that this would show up as a sudden loss of power with no advance warning?
Would appreciate your thoughts.
