Ignition Timing Adjustment - Virage TX / SLX / Pro 1200 / Genesis
Dynamic Ignition Timing, Cont.
12. Point timing light at inspection hole. Be sure to
view the mark at 90° to the window to avoid
misreading. Note the position of the scribed mark
in relation to the pointer.
13. If marks do not align, stop engine and reinstall dial
indicator in Mag end cylinder. Rotate the engine
until the mark is in the same position as sighted
with the strobe light. Read dial indicator and
compare reading to Degrees to Piston Chart on
page 7.2.
Ignition Timing Adjustment
To adjust ignition timing:
1. Remove flywheel cover.
2. Loosen magnet holder screws.
3. Rotate magnet holder to adjust ignition timing.
Rotating the magnet holder clockwise (as viewed
from the front) will advance the timing and rotating
counterclockwise will retard timing. Move the
magnet holder in the opposite direction
approximately the same amount as the mark must
move. Tighten screws securely.
4. Verify proper ignition timing with the timing light.
Static Ignition Timing Adjustment
Static Timing Light tool (PN 2871745) can used to verify that the hall effect sensors are working.
1. To check the sensors, simply connect the white test wire to the Blue (Cen) or Green (PTO) wire from the stator.
The light should come on and go out sharply (as indicated in static timing) if the sensor is functioning properly.
If the light glows or is slow to react, the Hall Effect sensor is damaged.

1. Verify proper ignition timing with the timing light as
shown above.
NOTE: When replacing a CDI box on a Virage TX, SLX, Pro 1200, or Genesis, it is very
important to check timing. A new CDI box may be programmed slightly different than
the one being replaced, causing ignition timing to be advanced or retarded too far.
