May have found he engine surge timing chains are shot. So at the moment the baby is in surgery. In four different shops at the moment. I'm doing a total rebuild trust me this is not for the faint of heart. Unless yuo know what your doing better have a trusted mechainic doing the work. This is the guy who rebuilt the 1982 Yamaha 750. so I know he can do it, I'm keeping a photographic record and costs a we go. So should be able to give you a feel for what this is like if you haven't done it before. With any luck about six weeks and 70 K should have a new bike. I'm taking care of parts cleaning myself, no way can a shop take the time to really clean up a bike that hasn't had it done in 13 years. So I will add to this as we go.
