not to argue, but I have done that test on many goldwing heads and have not had a leak. Could be the valve is slkightly bent, or the valve is not correct. They should not leak even a little

Agreed, they should not leak even a little, if a liquid under no pressure can get by the valve then the air/fuel mixture under high pressure will bypass it. This will give you a backfire and low compression on those cylinders.

Yes. tumb2
Although my GL1000 engine has never required internal repairs, I believe that is the best course of action for you to employ now. Ask for advice from other fellows that have been procuring cylinder head repair items for their GL 1000 projects.

Float valve assemblies? Are they OEM? I will not use anything but OEM float valve assemblies. Too many issues with aftermarket valves.

They arelike toilet tank valves. They let gas in when the carb bowls are empty. And shut off the fuel when the bowls fill up
