center of the handlebar grip as shown.
Hook a spring gauge 2 onto the plastic
tie.
Hold the spring gauge at a 90° angle
from the handlebar, and then pull the
spring gauge with a force of 10 kgf
(22 lb).

Speedometer display
1. Check:
Speedometer display
Does not display → Measure the speed
sensor output voltage and pulses.
2. Measure:
Speed sensor output voltage and pulses
Out of specification → Repair or
replace.
Within specification → Replace the mul-
tifunction meter.
Speed sensor output voltage
(dependant on the paddle wheel
position):
Less than 400 mV/
More than 11.6 V
Output pulse:
2 pulses/one-full turn
Measurement steps:
Apply DC 12 volts to the natural color
three-pin connector (between the red/yel-
low and black/yellow leads).
Rotate the paddle wheel by hand and
measure the voltage between the black/
yellow and yellow leads.
NOTE:
As the paddle wheel is rotated, a square-
wave voltage signal a is produced.
Two pulses occur every time the paddle
wheel makes one-full turn.
