1. Crankcase arrow
2. Scribe a mark here
3. Maintain verified timing marks aligned (static timing)
Checking Ignition Timing
Use timing light (P/N 529 0319 00).
To check the ignition timing, refer to illustration
and proceed as follows:
NOTE:
Engine should be cold when checking tim-
ing. Do not idle engine for more than 20 seconds
and make checks quickly.
1. Connect the timing light pick-up to a spark plug
cable and the power connections to the battery.
NOTE:
To avoid an incorrect reading due to paral-
lax, view the magneto flywheel and the crankcase
timing marks in a straight line.
2. Start the engine and raise the engine speed to
at least 2000 RPM while observing the timing
marks, refer to illustration. The magneto fly-
wheel mark scribed previously and the crank-
case arrow should be perfectly aligned. If the
marks do not align, a faulty trigger coil (check
proper grounding of coil) or a faulty CDI module
could be the cause: substitute one part at a
time and recheck timing marks (check connec-
tors condition prior to substituting any part).
NOTE:
Ignition timing may be verified when en-
gine speed is anywhere within 2000 ā 6000 RPM.
CHECKING IGNITION TIMING
1. Timing light pick-up on MAG side
2. Crankcase arrow
3. Magneto flywheel mark
3. Install parts which were removed.

WARNING
Place ski tips against a wall, raise rear of ve-
hicle on a stand, so that track does not con-
tact the ground. Do not allow anyone in front
of or behind the vehicle while engine is run-
ning. Keep clear of track and do not wear
loose clothing which can get caught in mov-
ing parts.
