Variator rollers for Honda Lead scooters. Under centrifugal force they push the pulleys apart and thereby change the transmission ratio, so the weight of the rollers affects acceleration and top speed. The name gives the weight of each roller: 9 g.
Replace them when the rollers are worn: flat spots and wear marks appear, causing jerking and vibration and reducing performance. The rollers are replaced as a full set.
- Before installing them, clean the variator of dust and wear debris.
- Tighten the fasteners to the standard torque and check operation at low rpm.
