be careful on the variator you use.. I had install dr. pulley sliders into Malossi variator and it didn't work well for a long time.. In the beginning, everything was good but after 2000km sliders inside the variator turned and it stuck.. we opened the CVT, checked everything, installed it back properly and it happened again again.. Then i read somewhere that malossi variator and dr. pulley rollers can't work together.. I don't know but I just ordered one set for my kymco 100cc and will use stock variator
anyway, for those who feel any issue in transmission, just take a look on rollers first
might be, or not, I dont know, I have only one experience with it, and it is with Bet&Win 250 engine
Looking forward for other experiences
