Anyone experience this valve issue b4?
Was about 800 miles from home and my TC88 blew a head gasket... or so I thought. It had all the familiar symptoms. Got it home, replaced said gaskets, only to get zero compression in the front cylinder. Investigated and found it has compression when the pushrods ar NOT installed. Any help would be greatly appreciated. It's an 06 Road King, with very low miles.

Solid pushrods... I was riding, going 70, nothing crazy and, I heard a pop/backfire and it shut down. Tried to start it and heard, what I thought, was it sucking air from the front head gasket. Now it seems the valves are being held open on the front head by the pushrods.

remove pushrods from that cylinder and then the modify your compression tester by removing the schrader valve and remove gauge install an air fitting(unless you have a leak-down tester) to put compressed air into the cylinder, if your valves are the issue you will hear air through the exhaust/intake. If it holds the air then one of your lifters is stuck (collapse in a vice to verify) and will need replacing. If your valves floated and you bent a valve there should have been a clear witness mark on the piston.
