3. Measure:
•Speed sensor output voltage
Output voltage not correct → Replace the
speed sensor.
Measurement steps:
•Elevate the front wheel and slowly rotate
it.
•Measure the voltage (DCV) of white lead
and black lead. With each full rotation of
the front wheel, the voltage reading should
cycle from 0.6 V to 4.8 V to 0.6 V to 4.8 V.

Rear suspension setting
The rear suspension setting should be made
depending on the rider’s feeling of an actual
run and the circuit conditions.
The rear suspension setting includes the fol-
lowing two factors:
1. Setting of spring preload
•Change the set length of the spring.
•Change the spring.
2. Setting of damping force
•Change the rebound damping.
•Change the compression damping.

Choosing set length
1. Place a stand or block under the engine to
put the rear wheel above the floor, and
measure the length a between the rear
wheel axle center and the rear fender hold-
ing bolt.
2. Remove the stand or block from the engine
and with a rider astride the seat, measure
the sunken length b between the rear
wheel axle center and the rear fender hold-
ing bolt.
3. Loosen the locknut 1 and make adjust-
ment by turning the spring adjuster 2 to
achieve the standard figure from the sub-
traction of the length b from the length a.
Standard figure:
90 ~ 100 mm (3.5 ~ 3.9 in)
