the rear wheel will only spin when the clutch shoes bite against the clutch bell ,ths is totally normal and it would stall if it didnt do this,if its a 50cc and has a race exhaust then put some 5 gram rollers in it.you get 6 of them

if the outer part of the variator is loose then it will do this,i take it thats what you mean by the outer toothed cog?you need to do it up very tight with an impact gun and use some loctite on the thread of the nut and crankshaft.

the belt gose around and the teeth cog spins, and kick the kick start it jams, and i think it unlossens the teeth Cog, the clutch bell turns when i use my hand just dosent spin with the bike and lots of smoke out the exhaust

take the transmission cove off and have a look in there,try to turn the clutch bell on the right with your hand and see if the back wheel goes around.if it doesnt or its a bit noisy and rough then the small gearbox that the final driveshaft goes into has more than likley run dry of oil and the gears and maybe the crankcase will be damaged.you can of course turn the back wheel with your hand and see if the clutch bell goes around too.

yes it revs ok and starts of electric start just the back wheel doesnt spin when u rev it

sounds like a partial siezure to me. However when you say for it going do you mean it revs ok? oris it sluggish and Lumpy. Will it start on the electric start?
