hey guys, I have recently acuired a early 80's(I believe) yt125. Has no suspension, besides the tire pressure, LOL. And I am wondering a few things. First, if it is supposed to take mixed fuel. And I have noticed that on hills it seems to want to bog down and stall out. The idle is rough, and if you don't keep the throttle open a little it stalls. Since I am new to the whole ATV world, I know nothing about how they work. But I got the thing for only $5.00, so I can't be out too much, I mean heck it does run good. And with 5 gears it seems to move down the road pretty good. If anyone can help I would appreciate it.
