NOTE : To avoid an incorrect reading due to
parallax, 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).
