FLYWHEEL FAN AND IGNITION SYSTEM
Caution should be used when removing flywheel Do not hit with hammer or other heavy objects
Service manual show flywheel to be removed with commercially available 6 puller Another method is
inertia type knocker that threads onto crankshaft end
The transistorized magneto ignition is fixed at 20 degrees BTDC and may not be altered in
any way Firing must not exceed 0 104 or 20 degrees BTDC
Quick check Turning flywheel clockwise if the leading edge of the depression of flywheel rim
where the magnet is mounted is not still under the right hand coil leg at0 115 BTDC it is probably
illegal and should be checked further If timing needs to be checked further see page 19
A Flywheel keyway or its position must not be altered
B Key may not be deleted or altered in any way
C Magnet and its position may not be altered in any way
D Magnet retaining screw may not be altered in any way Screw may not be replaced with larger
or smaller screw No heli coiling of mounting hole
E Ignition coil or its position other than air gap may not be altered in any way Coil mounting
bolts must be stock and cannot be altered in any way to advance or retard timing Coil attaching
bolts will be stock 6mm cap screw l 1 16 long There can be no more than 3 8 of unthreaded
portion of bolt that does not measure 0 230 diameter This restricts movement of coil to a
position that could make ignition timing illegal If a coil support mount becomes stripped it is
permissible to heli coil However only one leg may be repaired if both legs are heli coiled the
crankcase becomes illegal
F All nylon blades on the cooling fan must be intact
