Hello everybody,

I would like to install a 200cc cylinder on my vespa gts 125.

Witch mainjets should I order?



Hello Olly,


I´m sorry we can`t say this exactly. If you`ve got for example a other exhaust, airfilter on it so it`s also different. Best would be to buy several jets to find the right jetting for your setup.


Kind regards

Mario SIP
