Mechanic's tip: Roller weights are wear items. If your scooter shudders during acceleration or has lost top-end speed, the weights likely have flat spots and need replacement. Keep variator ramps clean and dry � do not grease inside a KYMCO or CN250 variator unless specified by the manufacturer. Check your variator slides for wear while the cover is off.
