hi all I'm looking to upgrade the sport city with a polini 198cc big bore kit and also a turbo but I'm yet to be ale to locate a turbo kit as such .
i found a turbo which is ihi rhb31 turbo charger there is also vz21 but both the same and i can fabricate the rest through friends but was looking for a turbo kit does anyone know of a turbo kit that fits these bikes or one that can be slightly modified to fit
THE REASON FOR THIS UPGRADE IS TO HAVE A SLEEPER BUT CRAZY WILD 125 SPORTCITY
