need help on Yamaha I.d

[SunShine777]

My nephew just took this in part of a trade he made, needs alot of work, but it'll give us something to do. I havent got a clue what it is Ive searched and searched only to hit dead ends theres no vin plate or nothing, hasnt ran in a while.

half the carb is missin wiring is all jacked up, been sittin so long theres mold on the motor.

only code I can find is on the bottom of the motor which is zhx98cm3

any clues as to what model or size it could be? thanks

That is a Yamaha Moto 4 100, probably 1985 or so. Good luck finding parts for that thing. Some of the stuff off the '87 moto 4 champ 100 might fit.

I wouldn't have known that....

It looks identical to the pic of the 1988 Moto 4 100, other than color.

I first found this image which led me to believe that was your machine. But when I tried to look up that machine on a Yamaha parts fiche, it does not exhist. However the 85 Badger 80 looks just like that. If you look up a Champ 100 on a parts fiche, the front fender is different than yours. It looks like a Badger 80, but the # on your motor indicates a 98cc engine. Maybe you have a Badger with a Champ 100 motor in it, or the Moto 4 100 does exhist, but is rare and obsolete.

I just looked at the pics again... It was an 80cc.

98cm3 would be a 100cc, but like you were told 'good luck!' A carb off just about any old 90 or 100cc can prob be made to work. check ebay for a carb off like a honda atc90- they are usually plentiful and cheap. Good Luck with that one- it's gonna be a project!
