Or, a "NOS YAMAHA FRONT MASTER CYLINDER ASSY 2G2-25850-00" that I bought on eBay today for my '79 XS650 Special. These were made for late '70s Yamahas, and are no longer made by Yamaha. I was lucky to get one.
Shoot...I even BOUGHT the motorcycle on eBay!
LOL. Shipping musta been rough for the bike.
Heading out to Sturgis?
