Setting up the variator and the clutch are of prior importance for optimal gear changing characteristics and a fast engine. In order to match the variator to the V-belt width and so obtain excellent acceleration, you will need these washers. They will be placed between the drive face and the bushing, this way allowing for adjustment of the distance between variator and drive face. If you want to get the most out of your scooter you won't get around setting up your vario, mainly relying on the concept of trial and error - but the result is really worth the effort! The set consists of 32 washers between 0.4mm and 0.8mm.
