Hi guys on the weekend I started my bike in the morning fine twice. Then went to go for a ride, took it off the trailer started and within 30 secs it stalled then wouldn't restart but would turn over fine. When I got it home I tried to kick it over but was locked. Pulled the rocker cover off to find the cam chain loose and skipped 2 teeth. Adjusted to right marks and started for a sec but stalled after a few kicks backfired. The bike would of done between 40-50 hrs. Has anyone had any trouble like this?
