Check ignition timing:

●

At every 5000 mile (8000 km) service interval.

Check for proper RPM and ignition timing as follows:

1.

See 

(Part No. HD 96295-65D)

 into timing inspection hole. Be

sure view plug does not touch flywheel.

2.

terminal and to ground.

3.

Be sure vacuum hose is properly installed at carburetor
and at vacuum-operated electric switch (V.O.E.S.).

4.

Start engine. Set engine speed by turning idle adjust-
ment screw clockwise to increase speed or counterclock-
wise to decrease speed. Use 

(SNAP-ON Part No. TMP23A) as shown in 

a. 

On world models, idle speed is 950-1050 RPM.

b. 

On California models, idle speed is 1150-1250 RPM.

5.

Timing light will flash each time ignition spark occurs.
Aim timing light into timing inspection hole. Front cylinder
advance timing mark should be centered in timing
inspection hole. If not, see 

6.

Set engine slow idle speed as described in Step 4 with
engine running at normal operating temperature and with
enrichener control knob pushed in fully. 

NOTE

●

Buells have an enrichener circuit that will cause the
engine to idle at approximately 2000 RPM with the
engine at normal operating temperature and the
enrichener knob pulled out fully. The increase in idle
speed is intended to alert the rider that the engine is
warmed up to normal operating temperature and that the
enrichener knob should be pushed in all the way. Con-
tinuing to use the enrichener circuit when the engine is at
normal operating temperature will cause fouled plugs.

●

Be sure the engine is warmed up to normal operating
temperature and the enrichener knob is pushed all the
way in before adjusting engine idle speed. Be aware that,
because there are variations in individual components, it
is possible for a properly warmed-up engine to idle at
2000 RPM with the enrichener knob pulled out partially.
