I there, this was the first time it hapenned to me.
I was runnig my buggy and suddently my engine suddently stoped.
When i tryed to start it, i noticed the flywheel was locked and when i opened it
my piston was broken just a little at his bottom (as seen in pic).
I cleaned the engine and it´s running fine.
Should i worry and change the piston or it will be fine for some time?
thanx

you need another piston andprobably also a sleeve I wouldnt advise to run that engine with out changing them
