Just put new top end gasket kit on my 74 CB550, rings looked good, valves OK, just a lot of carbon. Put everything back together, thought I had everything torqued right, went for a ride, smoked, I had oiled the piston and rings when I reassembled. Bro-inlaw shows up and asks for a ride, no prob Bob. Started up a hill near home running 50 mph pushing to hit 60 mph. All of a suden I hear the engine change tune and my left leg starts getting warm. When I pulled over there hanging out the side of #1 is a patch of head gasket the size of a quarter.
Bought a new torque rench today, now have to wait for a new gasket.
Good news, could have been worse.
