Hey Jack, hows it going? You had built a motor for me awhile back and I'm not sure if you remember or not but I only had about 5 or 6 tanks of gas threw it when the motor suddenly cut out one day. The bike wouldn't try and turn over and pull start wouldn't budge. I had emailed you and you thought for sure it was something with the clutch. I finally started to tear into the bike last night and the clutch was fine. I pulled the spark plug and and it looked like the plug had a bunch of melted metal all over the tip. I shined a flash light into the head and it looks like there is hole the size of a quarter in the piston face. What could cause something like this? The bike didn't have a chance to get hot, we were 10 min into the first ride of the day.

Thanks,

James
