to make it a short story, got project running, rode it for 10 minutes and it died, nut on flywheel wasnt tight and fell off,put it back on and she fired right up.
rode for a couple hours and it ran fine.
the next day took it out again , after 15 minutes she started to break up (poping out of tailpipe on left side) and overheating ,took it home did comp. test ,r side 140 psi, L side 10 psi.
took head off , hole in top of piston on left side ,( new top end) then i take clutch cover off and plastic impeller gear is broken in half, and what looks like a washer and c clip all bent up and mangled. came off the gear behind the clutch hub that goes to the kick start gear,
would the over heating problem do this to a piston ?
can i just change the bad piston ,the cylinder looks good .(top end has only 3- 4 hours ) ?
and do they after market impeller gear ,(not plastic)?
has this happened to any one else?
thanks for any help you guys can give me.
