My big riding buddy of the early 80s had one. the forks were crap and bent so he got new ones. The old stem didnt fit in them so he had to get a new stem. Then, the frame head tube was too long for the new forks and we had to cut a few mm off the top and bottom of the tube, and finally the new headset he got didnt fit the frame!!!!
Great bike ... as long as you dont wanna change anything on it. haha. I dont recon on it being worth much. Get some more pics and I will see if my mate wants it. It does look like its in good condition, but still along way of a collectable bike, Id say.
