Ski-Doo Ski Doo MX Z 2005 [1286/1429] Warning
Section 08 ELECTRICAL
Subsection 01 (IGNITION TIMING)
WARNING
Place ski tips against a wall, raise rear of vehicle
on a stand, so that track does not contact the
ground. Do not allow anyone in front of or be-
hind the vehicle while engine is running. Keep
clear of track and do not wear loose clothing
which can get caught in moving parts.
Connect the timing light pickup to a spark plug
cable.
NOTE: To avoid an incorrect reading due to paral-
lax, view the magneto flywheel and the crankcase
timing marks in a straight line.
Connect tachometer wire to spark plug wire or
aim tachometer toward spark plug wire without
using any connection wire.
Start the engine and raise the engine speed to
3500 RPM while observing the timing marks,
refer to illustration.
NOTE: Ignition timing may be verified when en-
gine speed is anywhere within 3000 - 4000 RPM.

1. Timing light pickup on MAG side
2. Crankcase arrow
3. Magneto flywheel mark
The magneto flywheel mark scribed previous-
ly and the crankcase arrow should be perfect-
ly aligned. If the marks do not align, a faulty
trigger coil (check proper grounding of coil), a
faulty flywheel, a faulty Woodruff key, a mis-
aligned (twisted) crankshaft or a faulty CDI mod-
ule could be the cause: substitute one part at a
time and recheck timing marks (check connec-
tors condition prior to substituting any part).
Install parts which were removed.
