Tuning ideas for my Vespa GT125?

Hi,

I'm looking to improve the acceleration on my Vespa GT125.  What is the best way to start?  I already have a PM62 exhaust fitted and this has improved the power slightly.  Any ideas or information would be much appreciated thanks.

Polini Speed Control or Malossi Multivar Variator will undoubtedly help and the Malossi CDi but ultimately the over riding factor is cubic capacity mate , you need a malossi or Polini cylinder kit and head.

 

 

Or of course you could part-ex it for a 200 or 250 ?
