Section 07 ENGINE MANAGEMENT (DI)
Subsection 02 (COMPONENT INSPECTION AND ADJUSTMENT)
The encoder wheel can also be inspected for bent
teeth by the following alternative method.
Remove magneto cover. Refer to MAGNETO
SYSTEM in ENGINE section.
Install a pointer wire on one of the threaded hole
of crankcase with the screw as shown in the fol-
lowing illustration.

Rotate the flywheel one time and adjust the point-
er so that it slightly touches the highest tooth. Us-
ing a feeler gauge, check and measure the clear-
ance between each tooth and pointer.

The maximum allowed difference between teeth
is 0.15 mm (.006 in). Otherwise, straighten the
tooth or replace the encoder wheel.
Properly reinstall cover.
Voltage Test
Unplug magneto connector.
Check connector terminals for corrosion or dam-
age.
Check the voltage readings on the harness side as
follows:
CONNECTION VOLTAGE
Terminal 4 with engine
ground
0 V ± a small mV
tolerance
Terminal 5 with engine
ground
12 V
Terminal 6 with engine
ground
5V
If voltage tests good, the CPS is defective and
needs replacement.
If voltage does not test good, perform the follow-
ing tests.
Resistance Test
Check the continuity of the wiring harness.
Disconnect the AMP connector number 2 on the
MPEM.
Using a multimeter, check continuity of circuits 6,
7and14.
If wiring harness is good, it could be either the CPS
or the MPEM. Try a new part one at a time. When
trying a new MPEM, refer to MPEM REPLACE-
MENT procedures elsewhere in this section.
Otherwise, repair the wiring harness/connectors
between AMP connector and the CPS.
Replacement
Remove tuned pipe.
Unscrew front engine support and slightly lift en-
gine to have access to magneto cover screws.
Block engine in this position.
Disconnect connector and remove magneto cov-
er.
Remove CPS.
