Just recently bought a Coolster 125cc ATV with Automatic Transmission (N/F/R). i have only ran it a few hours. I was out on some trails going up a hill and lost power.

Problem now is it starts up fine idles great, but when given gas/full throttle it barley move forware or reverse if at all. no power.. .

Transmission out so early? or just a belt problem> The chain has good tension.

I was in a lot of mud.

Any help would be appreciated.

 

Probably smoked the cvt belt, those machines are not made for hard riding...just puttin around on fairly level ground.

 

Does it have a belt? Those "Honda Cub clone" engines seem to have a centrifugal clutch, which is probably the problem, but I've never been able to work out how the "automatic" part of the gearbox works. Can anyone enlighten us?

 

How much do you weigh? those machines are meant for kids that are under 90lbs. Not meant for adults
