Ok - I built this ingenious device so I could test if tank and petcock leaked:
Of course it leaked, but not where I expected it to. It leaked around the lever, like if some gasket was missing.
But AFAIK there should be any gasket - right ?
Anyway - after emptying the tank, the petcock went off again
Will have to work it over again, more on this later...
As I' m still waiting for some parts and a paint-shop, I decided to have a look at the exhausts. They are nice (one of the reasons I bought this particular bike) but not perfect, and I intend to keep them as they are, at least for now and the next couple of summers.
So i started polishing the mufflers - again, not perfect condition, but definately acceptable:
You can get a set of repro pipes from Doremi, but they are out-a-stock for now. Not sure about the quality, but at least theay look nice on the web
The Exhaust pipe holders (18069-024) were in very good shape. You can get them on Ebay, but these were made looking sharp again, after a bath in my Ultrasonic cleaner. The various muffler clamps are new, though:
Adding some new copper gaskets for the exhaust + some nuts and spring washers, things came to look like this:
