Hey Randy,

Not sure what year it is, I was told when he orders parts he orders for a 99′ model.

The cylinder has been stripped and recoated MANY times so I’m sure the plugs have been removed. I was going to glue them in with Devcon and move on but wanted some input into the chance this was a common issue with a simple repair.

Timing, CCV and squish were all way off. All or any combination of these can cause the seizures but it always melts the piston just at the area where the leaking plug is at.

Thanks for the info!
