[#20] Variator Collar Yamaha OEM (BWS 2002-2011)

Originally, your belt is very often pinched between the variator cheek and the ventilated pulley and this causes you to lose performance. To overcome this problem, simply remove your ventilated pulley and check that your belt is not in a vacuum. If it is in a vacuum, you will have to compensate by adding washers up to the edge of the belt (it will therefore no longer rise when you put your ventilated pulley).
