Thanks for the advice Andy. I will have a look when I next get some time.

Either way I am looking to sell the bike. It was supposed to be a project, due to the unknown history of the bike my plan was to rebuild the engine. But I no longer have the time and so this bike is just sitting in my garage and aging when I would much prefer it go to someone who can give it the time and looking after that this piece of bike history needs. What do you think is a reasonable asking price for a bike like this?
