my top piston has committed hari kari!!
lost compression on it , so looked up the port and the top front of the piston is missing above the rings.
it hasn't seized so i'm hoping cylinder damage is minimal!
got most of the bike apart tonight just gotta prize the cylinder off to have a proper look tomorrow!!
everyboby say a prayer for me !! lol

whats the likely cause? thought it might be blown head gasket damage??
