vespa 50 cc tuning

I would like to tune my vespa 50 special V5B3T but i don't know what to start with.

Do you know some small changes that will increase my performance?

 

Thanks!! :)

I'll go for the 75 polini and 16/16 dellorto shb carb.

I already put a seriepro sport exhaust underneath..

For example:

you can change the cylinder with 50ccm to one with 75 or 100ccm. Next you can change the carburetor to a bigger one. But you mus also set the ignition. With this changes the vespa a little bit faster and with more power. You can also put a sporty exhaust on your bike.

I know my english is not pretty good, but I'll hope I could help you!
