Yamahas mechanics specials Unsure of years on all. 4-zinger is from the 80s. 4-zinger ran good. Needs the pull cord repaired and an air box or some sort of aftermarket air cleaner but ran when parked a few years ago. All would need new carbs at a minimum. The PW also ran when parked. Rear tire deflates after a day or so and didn’t want to figure out how to take the tire and assembly apart to change the tube. 3rd one is a chinese or Korean youth model. I’ve never heard it run. Could never figure out its electric issue to get it to turn over. Just tried to jump it from another 4 wheeler have the front plastics inside to put it back together. I know it needs the left side brake lever that also has a safety switch in it to get it to turn over. Anyone with some time and mechanical ability can get them going pretty easily. Tired of them taking up space and kids have out grown them before I ever really did anything with them. Want to sell all as a package deal 650 obo
