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 point timing light straight
in line with the crankcase timing mark. Bring
engine to 6000 RPM for a brief instant.
TYPICAL
1. Timing light pick-up on MAG side
2. Timing inspection hole
The magneto/damper mark must be aligned with
center mark. If not, move trigger coil as explained
above and recheck ignition timing. Tolerance is ±
1°.
If the marks still 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).

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.
