Hi guys


Well I managed to get variator off,put on new belt all back together.
Charged battery the scooter started.oh joy I said.


Took it up the road for a spin and well it hardly moves.
Acceleration is less than half what it was only got to 30mph .
Its a 250cc that used to sit at 70.


Any ideas before I pull it all off and throw a strop in the garage?

Cheers

Did you get any oil or grease on the belt or the pulleys?
If you can tension the belt is it correctly tensioned if not is the belt the correct length?

The rollers probably have flat spots.

wrong sized belt? Rollers should of been replaced as well.

Hi guys


Cheers for replies.
I will hopefully have a look today.
The scooter is awful to work on.
The previous owners managed to square off round and grind every bolt.
I think it could be when I put the belt on I pulled the clutch roller(the rear one) out fully to put belt on ,now I guess I should have pulled the belt so it sits stretching belt more?closer to the outside?if that makes sense?


Many thanks again guys

I had this once bbefore on a scooter. The rollers weren't seated right. Hope this helps

check also that the front pulley nut is done up tight!

A spacer in the wrong place in the variator/crankshaft,
