My word I use to ride one just like it. I had a Yamaha YZ 80 and a friend wanted to ride it so we would trade off every now and then. Not to often though. My YZ was built by the owner of a Yamaha dealer for his son. They rebuilt it before they sold it on the showroom floor. That thing was a beast for a 80cc bike. 400 hundred bucks back then. Can you believe how much things have inflated since then. Hell in 87 I bought a brand new Mustang GT for exactly 12,975.00 out the door. They are way over double that now. Those were the good old days.
