I bought this bike, running, with a title. It had sand in the gas tank. The previous owner tried to sand blast the rust out. Also, while riding the bike, it sheered the woodruff key off. The previous owner never tightened the nut that holds the flywheel in place. Other then that, the bike was a great experience to restore. Now for all of the before and after pictures! Enjoy!
