Does anyone have any idea what a 77 r60/7 would be worth. Valves set and fluids all changed. Trans has all new bearings and seals. Instruments rebuilt. Fresh paint and pinstriping. Tank lined with Caswell. MAC mufflers. Actual mileage unknown. Seat has been recovered w/ a gel insert installed. New avons w/ less than 100 miles on them. Only thing it needs is under tank master replaced, resleeved, or ? New piston and gaskets didnt fix the leak. Prob a good candidate for resleeving. Runs, rides and shifts great. What are your thoughts?
