1. Fan cowl timing mark
2. Yellow fin
If marks do not align, there is something wrong
with fan mounting. Check Woodruff key and fan.
CAUTION : Always check the timing with
a stroboscopic timing light at 6000 RPM
after the marks have been checked.
Checking Ignition Timing
NOTE : To perform this procedure we
strongly recommend a stroboscopic timing
light which is able to exceed 6000 RPM.
To check ignition timing, use a timing light (P/N
529 0092 00).
NOTE : This timing light is battery powered
(2 alkaline batteries, type C) and therefore
needs no auxiliary power supply. If a different tim-
ing light requiring auxiliary power supply is used
on manual start models, use a separate battery to
power timing light.
TIMING LIGHT (P /N 529 0092 00)
The ignition components are affected by temper-
ature variation, therefore, timing must be checked
when engine is cold, after idling for a MAXIMUM
of 20 seconds.
NOTE : On applicable models, turn heating
grips off prior to checking ignition timing.
1. Connect timing light pick-up to the spark plug
lead. Use a digital induction type tachometer
(P/N 529 0145 00).
TACHOMETER (P/N 529 0145 00)
Connect tachometer wire to spark plug wire or
aim tachometer toward spark plug wire without
using any connection wire.
WARNING : Place ski tips against a wall,
raise rear of vehicle on a stand so that
track does not contact the ground. Do not al-
low anyone in front or behind the vehicle while
engine is running. Keep clear of track and do
not wear loose clothing which can get caught
in moving parts.
2. Start the engine and point timing light straight
in line with the fan cowl timing mark. Bring en-
gine to 6000 RPM for a brief instant.
