Progressive Insurance has full coverage for about $90 a year that includes Towing. I just used the Towing option. I was 12 miles from home.
A flat bed Tow is over $150 around here.

Going with Flo really does work.

Was this scoot running a bbk? Any mods?

carasdad. I Agree completely, timing chain tension should be checked and adjusted as a maintenance item.

I also agree with the timing theory. If the timing is off it can mimic some of the fuel ratio theories and if it is really bad you can slam the valve and piston together (I think but don't know for sure that these are interference motors).

It looks to me like a classic case of metal mice infestation, the bite marks are plain to see on the head!
Jokes aside beside the previous ideas a too tight valve that runs hot due to not being able to get rid of it's heat to the seat will weaken the valve and possibly cause it to break as this one did.
