I have a tired Laverda Ghost 650 that seems to lack compression in one cylinder at idle, but picks it up as revs rise. It´s slowly gotten worse to the point where it stalls at standstill. Before I start pulling the head off, I need to know that I can source a head gasket and possibly valve guides and other top end bits. Can anyone direct me to a supplier. The bike is loads of fun to ride and quick once you get stuck into it so I´d like to hang on to it as a second bike, great around town. Any ideas would be greatly appreciated. Cheers, Roc.
