I'm not so much trying to sell this machine as I am to find a substitute for the carbs. I can't get it to run right and have narrowed the problem down to the carbs. It seems Yamaha only used these particular carbs for a short time and it is virtually impossible to find parts for them. What I need to find is either a source of parts or a substitute carb that will work on that particular motorcycle. When I get it running properly I will be selling it though. Or, at least putting it up for sale.
