New guy on this site but have long been interested in any such. Learned to ride in 67 on a Honda Super 90. Have worked on many including my son's QA50 in the early 90s.
Is this wrecking yard known here? I've visited but never purchased anything. It is a horrible jumble of rusty hulks, but there is treasure within. Near Rye, Arizona, north of Phoenix:
All Bikes Sales
The owner is rude and crude, shows absolutely no interest in helping or selling. Still, lots of old rusty hulks and a little bit of everything.
