While on my merry way back home to Texas from the Hamburg, NY national we were between Akron and Columbus Ohio when, while doing 73 mph on cruise in fifth gear my revs shot up to about 7500 and the bike slowed down. I dropped it into 4th and limped 15 miles into Ashland Ohio. We are in a motel room and I guess I'll be looking for a U-Haul that will hold both bikes and my bunkhouse trailer. Since the contaminant is engine oil (I know this from the weep hole I drilled) I'm going to assume I've been "O" ringed. I really did not want to do this job with only 26,000 miles on the clock. I guess the "high" quality BMW O-ring hardened up over 16 years and decided to fail. That's my luck, I do every premptive repair that I can and still get bit. OK time for a glass of wine or three.
