Nice job on the 175! It (a blue one) was my 2nd bike, after killing a Honda 100.
I never killed the Yamaha BTW.
I currently have a yellow 1971 AT1 125. It's in great shape other than the hi-beam/lo-beam control button has been broken off. Do you know of a source for, or someone that restores/refurbishes those controls for the early Yamahas ?
If so, could you PM me please. I don't check here too often.
Thanks and ride safe!
