Clutch problems

[Matuna3343]

When i drive my scooter at a constant speed for example if i drive it 40 km/h for like 3 mins and then when i give it gas it like stops i mean it drags the back wheel and then suddenly accelerate. Also when i go downhill and i let of the gas completely so it drives on idle downhill and then when i give it gas it stops and then starts to accelerate i think that is normal for downhills but i think it shouldnt do that on flats. Does anyone know what could be the problem i also need new set of rollers but i dont think that is the problem

Sounds like carburetor is out of adjustment.

Check the wear of the variator, rollers in the firs place, then the 3 clutch springs to be in position.
