na then agen, jus quickly wat weight rollers will work best with a speedfight with a laser x-pro on. cheers
a discription of your setup would be nice i think. if its bog standard i would say drop them by a g or two
ye soz m8 forgot i wus in a rush. speedfight 2 air cooled: polini 70cc sports kit 17.5mm carb so far.
Speedfights usually run on a little hevier rollers than piaggio enignes i would say 6.7 or 7.0g should be around perfect
no problem mate 6.7's are cheap on donotlink i think they are £3.25 ask if you want the link
