I have a problem with a high compression GS1000 engine- the man who owns the bike was told to run copper head gaskets in his 12:1 compression GS1000 but the copper gasket is leaking oil in a bad way. There are no o-rings in between the head/jugs, just the gasket. I’d like to switch to MLS or find a way to stop this copper one from leaking. Any suggestions? I’ve got no experience with copper head gaskets whatsoever
