Modern Vespa

I have a stock vespa lx 50 2T and I want the best first bang for the buck mod. Is the malossi multivar 2000 a good option? Do you suggest any other mod first? If the multivar is a good option what will the result of this will be? (Better acceleration? top speed?...) any answer will be much appreciated

Big bore kit
Expansion Chamber
Racing Variator

In that order are the most bang for the buck. You probably can't find an expansion chamber for the LX 50, and they do tend to piss off everyone around you, especially when you decide to ride home at 2 AM. So big bore kit and variator are going to give you the most. Malossi is as good as it gets when it comes to performance variators.

malossi 70cc top end kit, leo vince SP3pipe (remove the restrictor), red malossi airfilter, slight upjet on the carb. change the rollers in the stock vario

done. 55 all day, can still get up hill, reliable.

*edit to add, moto is right. throw a vario at it as well.

but kit first. then everything else compliments it.

Since there are two authorities on mechanics and modification (greasy125 and Motovista ) i wanted to ask something ...
Does the ribbed on which the variator rotates wear prematurely if stressed beyond the manufacturer's specifications?

i have no idea what you're asking about.

show me a parts diagram with numbers and specifics and maybe i can tell you?

anything performance wears out faster and requires a closer eye towards maintenance.
