right i have the very same bike what you have to do is go under your seat remove the inspection panel to see carb remove the top of carb 2 screws then take off there is a big spring under there so lift up slow inside that spring there is a long bolt with a adjustable nut un it use a pair of pliers and just wind it down to the base and tighten put back together and your done it has no restrictions anywhere else ok it then goes like a rocket ohh just to let you no if you change the roller weight in there the stock ones are 5 grams i suggest to change to some dr pulley ones i have done this and its like a totally diffrent bike piss all over other 50cc sooters do it and see

are you asking the right question, if your bike didnt have a variator it wouldnt even move m8, the restrictors are on the crank next to the variator and the cdi is restricted, so you need to buy a new one search on the net for a company called llexter
