just put a viper exhaust and 8g clutch roller on my speedfight 2 and it is very slow up hills and its not much better on the flat has any body got any advice on how i can make it go quicker thank you it had 6.7g rollers in before
you will need to use slightly lighter rollers and upjet the carb, standard is 72, and you should put it up to 78 also check the air inlet tube into the carb you should be able to see 2 little round induction holes and they should be blue in colour, if they are white go and get yourself a second hand air intake off a early speedfight and fit it to it it will now run a lot better
