hi all,
when the scooter is running and i have stopped on a level ground, if I'm not holding the brakes, the scooter want to move forward at a low speed.
i have replaced the belt, rollers ,sliders last week, for maintenance.
Clutch lining thickness are in tolerance.
thanks

Clutch shoe springs could be worn out. There are 3, one per shoe. If they don't have the tension then when the clutch springs spin they could rub on the clutch bell and cause the bike to creep forward.
Also check your idle speed, should be less than 2,000 rpm.
-
If it isn't too fast an idle speed (above 1700rpm), did it creep before you changed the CVT parts? If it only happened after the change I'd check to see if the belt is the correct size, the rollers are correct weight, etc. Compare the new parts with the old in other words.

If after idle speed is set correctly-----bike still creeps, just use brake to hold. Don't things apart until necessary.

it creep before the change.

What is your idle rpm?

@ModChiP, what I would do:
-CVT cover off
-compare new belts width to old one (maybe the new one is a tick wider?)
YES/NO
-start motor (on main stand -rear off ground-front brake pulled),
check your clutch bell during running for unusal signs like deformed (oval) or bluish (burned out)
YES/NO
-new belt off again, compare with old one
(is the new one significantly shorter?)
YES/NO
-CVT front pulleys: is there a shim missing during reassambling
YES/NO
Pls check this out and give us a feedback to go further.
