take the washer out of the transmission it is behind the front half of the variator,then cut the disruptor pipe from the exhaust pipe its the one that doesnt go to anything wels a washer over the hole after,then pull a brass plate out from th back of the carb and take the throttle slide out from the top of the carb and move the circlip to the bottom slot on the needle (one nearest the pointed end) hey presto de restricted :)
