Need help with a tuning kit, how do you tune your scooter, which kit should I choose, and all general tuning and modifcations questions are for in here.
I have the V4 and the Avanti ex box.the v4 seems well made,fits well,performance wise nice power spread but nothing special at higher speeds.the ex box.all the good points of the V4 plus more poke top end.cannot fault it,worth the extra few quid imo.
