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
