1981 Yamaha IT175 H

This was a project that never got started.
I think that it would have been a much better bike the the IT250 I got in the same deal but, I started on the 250 because it seemed like less work to get running. If I was to do it all over again, I would've started with this guy.

As it was, it got sold off to fund the 250 restoration
