3-8 Settingpoleshoeairgaps
1. Loosen two bolts (A) and insert Module air gap
gauge: 91004 (B) or 0.3 - 0.4 mm (0.012 - 0.016
in) thick feeler gauge between ywheel (C) and ig-
nition coil shoes (D).
2. Rotate ywheel (C) until magnetic poles of y-
wheel face ignition coil shoes (D).
3. Hold ignition coil against ywheel (C) and tight-
en the bolts (A) (Refer to “3-7 Replacing ignition
coil”). After tightening bolts, remove Module air gap
gauge: 91004 (B) or feeler gauge.
NOTE: When air gap is too narrow, contact with
ywheel may result. When the air gap is too wide,
spark is weak.
4. Reassemble all removed parts.

2. If magnetic force is weak, replace ywheel (A)
as follows.
3. Open cap cover (C). Disconnect spark plug cap
and remove spark plug.
4. Install clean rope (D) in spark plug hole (E) to
stop crankshaft rotation.
NOTE: Do not use piston stopper to avoid piston
