Motorcycle Repair: honda cr 450, blown head gasket, honda cr 450

Question
2006 honda cr 450  like it siezed while out on it , once home bike started ok , while idling engine stopped suddenly a pool of coolant appeared under the bike now the engine seems to be siezed again , any ideas ? thanks ,, jim.

Answer

Hi Jim,

I would check for a blown head gasket as it sounds like the engine
may be hydro-locking rather than seizing. It may be pulling coolant
into the cylinder and locking up the piston.

Check the oil for coolant and pull the spark plug for a look and see
if the cylinder has coolant in it.

Hopefully the damage is minimal.
