Installation Notes

  • Start from stock weight; adjust in ±0.5–1.0 g steps to reach target RPM.

  • For testing, you may alternate two weights; final setup should use one uniform weight.

  • Keep ramps and sleeve clean and dry; do not grease rollers or ramp faces.

  • Inspect belt width/condition; worn belts affect the shift curve.
