Hi there,currently i have a 2004 speedfight 2 50 and have been wanting to upgrade to a 70 kit but need some questions answered before i go ahead and buy the parts and pay for the fitting as i am pretty useless myself and do not wish to break it before its even worked. :good: first of all, best kit for it? i was thinking polini sport iron kit? what else would need to be changed? im not looking for a really expensive full refit just the basics that will give me a better accleration and a bit more top end, bigger carb? new inlets? cheers
I can't believe no replied to this ? Is your bike Ac or Lc i'd highly recomend a Ac Polini sport, But if water cooled i'd go for malossi sport (Polini known for blowing head gaskets) You'd need to change your rollers and upjet by like 5%.
