One owner bike originally had a sandcast motor, but the owner threw a chain (very common thing with the first generation 750's) Honda replaced the motor with a later non sandcast motor however if you have a sandcast motor this the bike to start your restoration with. Bike needs to completely be restored motor turns over and is free. Bike has a 4 into one pipe on it. I also have very collectable original manuals and stuff to go with the bike and original title.
