It's probably my own fault. The battery on my bike died yesterday evening and I had to bump start it. I completely forgot the big hill that I had to get up to get back to the road, and I tried to balance keeping the revs high enough to maintain a spark with fluttering the clutch to get up the hill. The hill was only a few hundred yards long, but when I got to the top, I completely lost power in any gear. My first inclination as that I've burned out my clutch shoes. Has anybody had any experience with that?
