another one bites the dust
so today me and a few buddies went out, he has a 05 rxp with 70hrs on it, both skis were (WOT) and his cut out. tryed to start it back up and it was locked up,pulled the plugs and the middle plug was smacked by the piston,mind you his ski is bone stock. what could of caused this ? all the plugs we pulled looked really brunt and the motor was really hot.
also if you have anyone that could help him out please pm me.

quite possibly dropped the head off a valve which has locked it all up.
if the ski is not winterized correctly and left sitting the valve stems can get rusty weakening them and eventually they snap off!
otherwise timing chain may have broken but until you remove the rocker cover you wont know.

how bout this for a guess:
ceramic washer deto'd. Pcs got stuck in timing chain..which broke or skipped. Valve hit piston. Pcs of valve smashed spark plug. Mess in engine.
thats my story an ahm stickin to it.
let us know when it's torn down.

Sometimes when water intrudes a cylinder the plug will look as if it has been hit.
