What happened to this engine? I was trying to ride it ~100 miles roundtrip to a motorcycle show in Kansas City, but I had not tuned the engine in a few years. I only got about 20 miles when I started to slowly loose power, I was at full throttle but could not keep up with highway traffic. Then suddenly I lost power completely. When I finally got the bike back home, I checked compression and one cylinder had no compression at all. Clearly I needed to open up the engine and see what happened.

This is actually the 2nd time I've rebuild this engine due to a broken piston! Safe to say I'm a bit of an expert at this point (and yet I still made many many mistakes, as shown in this video).
