No, I don't think so. I was just out on a boneyard prowl looking for stuff for my '67 Dodge. I saw this sticking out of the remains of a shed and couldn't resist finding out more about it.
From the general shape, it is obviously a 60's Yamaha. From the 350 marker, and a marker that reads "oil injection", I think it is a YDS3. I recall that those were imported here, but don't ever recall seeing one. Any other ideas?
