  • In this video we show you guys our mini 2 stroke dirt bike find! We bought this vintage Yamaha bike at the Pate Swap Meet this last year and got to drive it a little bit then but nothing too crazy. We found that in our short time driving it there were issues with it staying running and not cutting out at the top end. With a little bit of carb tuning we were able to get it running just fine and hit the power band very nicely. After we got this mini dirt bike running good we took it out to our favorite spot and gave her a rip and raced our cj mini bike with a built predator 212!
    Thank you guys for watching and be sure to stay tuned for this thing to get a full cosmetic restoration!

    Good to see, I have a Suzuki TC125 from 1972, I got it for free from a dude i know, needed new points, condenser and coil as well as me welding the kick starter back together and cleaning the oil pump. It runs well considering the top end is bad due to previous owner running without air filter. I plan to get new top end, repaint, tidy up etc when I get older and have more money, I'm only 16. Btw it's the one with the dual range gearbox. Low range 1st gear can climb anything, it's awesome

    Ah fun vid! My first dirt bike was a 1980 Yammy MX 100 I bought new when I was 16. Paid for it with my paper route money. $600. Been through a lot of bikes since then and now have a '18 KTM 690 Enduro R.

    I was 8 in 1980 and I got a brand new one for helping muster sheep with my dad on our farm in the Highlands of New South Wales. I loved this bike. I rode it hard until about 13 then moved onto a bigger bike. It sat in the shed for nearly 15 years and once it had all fresh fluids and a new spark plug in it started after 2 kicks.
    Thanks for this video just hearing the sound of it brought back great memories of me, my bike and a .22 slung over my shoulder. Good times.

    This was my first dirtbike. Mine was a 73. I just sold it to a buddy. There fun little bikes. They made a street legal version also called the gt80. The holes on the fenders that are plugged are where the lights went. There is a blank plug on the left side of the engine where the speedo cable goes

    Nice bike you guys, I just sold mine back in June. I’m not very well versed on these, but the one I had was the gt80, essentially the same bike except mine was street legal. I don’t know if the mx80s were or not but it would be cool to find out and add back all the lights to make it legal again.
