Do you know what should be thickness in cork plates and in discs. There is some variations in SIP webstore and I really don´t know what packet is right to my 50R.

Re: SPEED PROBLEM WITH 1977 VESPA 50R IMPORTED FROM SWEDEN

Hi,

that is great news. I was worried that I have to open transmission also.
Thanks for info :)

Maybe I have to change clutch too, and think what is right primary ratio because I have 75 cc inside :)
Any good advice what would be the right primary ratio?

SPEED PROBLEM WITH 1977 VESPA 50R IMPORTED FROM SWEDEN

Hello,

I have problem with my Vespa what is imported from Sweden to Finland. This Vespa belongs to moped II-class and I have changed a new cylinder and crankshaft.
Still it runs only 30 km/h. It is restricted by transmission/gearing.

Does anyone know what I have to change to speed up my device?
