IGNITION TIMING
NOTE
Use static timing method if inductive timing light is not avail-
able.
Dynamic Timing
1. Remove hex socket timing plug from timing inspection
hole, which is located on right crankcase half and
centered below engine cylinders. Install TIMING MARK
VIEW PLUG (Part No. HD-96295-65D) into timing
inspection hole. Make sure view plug does not touch
flywheel.
2. Connect leads of INDUCTIVE TIMING LIGHT (Part No.
HD-33813) to spark plug cable, battery positive (+)
terminal, and suitable ground.
3. Make sure vacuum hose is properly installed at
carburetor. Start engine.
4. Make sure sidestand is up and transmission is in
NEUTRAL.
5. Set engine speed to 1200 RPM.
IMPORTANT NOTE
When checking ignition timing, always check at the RPM
listed. Failure to do so may result in running engine with
too much spark advance, and may cause extreme engine
knock and engine failure.
6. See Figure 7-21. Timing light will flash each time an
ignition system spark occurs. Aim timing light into timing
inspection hole. The advance timing mark (two dots)
should be centered in timing inspection hole.
a. If this is the case, ignition timing is properly
adjusted. Go to Step 11.
b. If timing mark is not centered or is not visible in the
timing inspection hole, see to Steps 7-12.
7. See Figure 7-18. Drill hole in location shown and remove
outer timer cover, if not removed.
8. Loosen module plate screws just enough to allow sensor
plate to be rotated using a screwdriver in the plate's
notch.
9. See Figure 7-21. With timing light aimed into inspection
hole, rotate module plate until advance timing mark is
centered in timing inspection hole.
10. See Figure 7-18. Tighten module plate screws to 10-20
in-lbs (1-2 Nm).
11. Install new outer cover, if removed.
12. Remove TIMING MARK VIEW PLUG from timing
inspection hole. Install hex socket timing plug. Tighten
timing plug to 10-15 ft-lbs (14-20 Nm).
