To correctly install the speed kit, please follow these instructions:
1. To mount the phonic wheel on the jackshaft, please remove the pinion
and insert the phonic wheel (internal diameter ¾”) on the jackshaft
2. Fix the phonic wheel to the jackshaft by screwing the M5 locknut (use the
hex key supplied with the kit)
3. Install the magneto resistive speed sensor on a self-made bracket. It is
reminded that the
sensing distance
(i.e. the distance between the sensor
and the phonic wheel)
must be 0.15 – 0.3” (4 - 8 mm)
Plug the speed sensor’s male connector into the gauge’s SPEED input
