110cc Yamoto runs but won't go
 

My sons 110cc yamoto is a fully automatic with a shaft drive and this weekend it quit going.....meaning it runs prefect but when you hit the gas it does not move...I took the clutch cover off and everything looks normal but it is hard for me to tell since there isn't a shop manual available for it. I was wondering if anybody has had this issue and what they think the problem might be. Any help would be greatly appreciated because I really don't feel like tearing the whole thing apart and trying to "hunt" for the issue.

I'm having the same problem with our 150cc. It runs but it doesn't want to stay in gear. Automatic

your 150 really doesn't have gears, your automatic consits of a clutch, a variator and a drive belt, so you eaither have the drive belt slipping or it's the clutch slipping, you need to remove the cvt cover, and see if the belt is loose, then start it up and watch the belt to make sure it moving up and down on the pullies,
