Bike died load bang have compression but won't start

@jamesrandall93 I would check all of the wiring and electrical connectors. If there is any corrosion on any of them, then give em a good clean and apply a blob of vaseline to stop em rusting in the future. If something is not earthed or shorting out that would give you problems for-sure.

Piston rings have a hard life in a 2 stroke travelling over the open ports. I've seen the pins that stop the rings rotating on the piston move, allowing the ring to spin and open end catch on a port. With it being under load at time it failed (going up a steep hill), I wouldn't be surprised if piston expanded due to heat build up and pinched the rings. May have been running on the lean side aswell.
