It is not worth that much money. I would say $2,000-$3500 would be a realistic price. Currently you will not get back what you put into restoreing any Japanese bike unless it is something like a K0 or K1 CB750 or a H1 or H2 Kawasaki. Just at this point and time Japanese motorcycles are just begining to get noticed and appreciated by the AMCA, and it will take sometime for them to start going for money that approaches what a British bike of the same year .
