Title: YZ50
Post by: Snaggletooth77x on July 22, 2022, 09:51:53 AM
I had my 1980 Yamaha YZ50 for some years now and it has taken a lot of adult abuse. After storing it in the shed for over a year I pulled it out and fired it up third kick. I did a once over and noticed a full break in the left side of the frame and two cracks on the right side. Time for a full tear down! Fixed the frame, controls, tires, oils refresh, clutch, new plastics, graphics and reeds on the way.

Awesome! I love the air cooled stuff. Clearly it isn't as fast, but there is a charm to it. Not having to deal with pump, radiator, etc.. It looks so simple. How does that monoshock still work?

Fairly simple to weld back together with the full teardown taking a mere 30 minutes.

side note, moving this to the micro muscle section.

Thank you for relocating, my bad.

The monoshock is in good working order, I also realized that I could stiffen it up from what it was previously set at. The forks are not is as good of shape.

No Isle of Stan wins under its belt but at least a couple Felony Flats wins.

Just race bearing and fork seals to install. Finished the seat cover yesterday. Ready for another 40 years of abuse!
