My buddys got a 06 aircooled speedfight 2,was standard apart from de restricted. Just fitted a 'techno racing' exhaust or something,and some 5.7 rollers that came with it. Now when he first went on it,it accelerated ok,then got to 30,then he turned around and came back and struggled to get 20. (Hes not legal yet so it was only up the road). Could it be the rollers atall? What else could it be. :wtf: Would be good if any of you could help soon as poss,ment to be going round his 2moro to have a 'look'. Thanks.
