Well I ride at my uncles house and the field is about 3 acres where I like riding the little dirtbikes we have. We have an atv and 3 dirtbikes, 50cc, 80cc, and 90cc. Well the 80cc needs a smaller carb because it floods out and it is shot,it also has no gears. The bike is a straphical (sp?) where it is like an automatic.

It just catches as you give it more gas. Well Im almost 16 and I have virtually no knowledge of atv's besides the no brainer stuff. It is a racing machine and prob. goes about 55mph. I want to get it running again so does anyone know a proper carb for this 80cc bike and how much they cost? After I buy the parts (if its even worth it) I would then need some help installing them. So could someone point me in the right direction?? Thanks!

This picture I think might look something like it but I couldnt see it well as its in kind of a dark barn.

no offense, but if thats the bike i think it it, they dont have any parts. pep boys and other stores sell bikes like that with no brand and u can't get any parts for them. u can by those bikes on ebay but you cant get any parts for them either. sorry.

It looks like a Yamaha PW80
Is it a two stoke?

yes 2 stroke. Its like a racing thing. Also I guess its a 1977. Lol kinda old.

actually I think its newer because of how it looks. Step dad guessed cause he bought them in like 1989 or something liek that.

Ok I am sure it is a PW80 platform. I would look up a parts list for a Yamaha PW80 and order a new carb or just take it somewhere to have the carb rebuilt. They are cheap to redo.
