Does anyone know any common faults with these? I guy I know picked up a load of bikes at an estate sale and one of them is a fairly tidy looking, stock and original, CL350. I gather he is thinking of selling most of them on swiftly, including this one, and it might be of interest to me (if it's cheap enough). However, he said that it does not have any compression. Any thoughts as to what the cause may be? It doesn't look like it's stood for many years & would have valves rusted open, I'm wondering if they are prone to other problems- maybe it could even be a broken kickstart mech...
