Naraku Variator Boss Shim 18mm Set (Aprilia, JOG, Zuma 50)

Naraku Variator Boss Shim 18mm Set (Aprilia, JOG, Zuma 50)

Description: Naraku Variator Boss 18mm Shim Set for 40QMB 2-stroke engine. Variator control shims can be installed between the drive faces to lengthen the boss if your variator does not open fully to allow maximum belt travel. Also fits stock variators on Yamaha Jog, Zuma and Vino, Aprilia SR50, Malaguti F12 and F15, Adly Silver Fox and Thunder Bike, and many more models that use a horizontal Minarelli engine.

Installation: 1. Slack the belt by opening the CVT clutch gives belt slack to the variator side. 2. Then install the variator drive face while lifting the slack belt further away from the center boss if done properly should not see any splines between variator drive face slop-side and boss flat-side. Should be flushed together. 3. Then install the existing variator fan, washer, and hand-tight nut. 4. Finally, apply blue Loctitetorque nut to 30-35ft-lbs. For reassurance please consult your manufacturer's variator torque specs.
