IGNITION TIMING CHECK/ COMPRESSION PRESSURE MEASUREMENT

Spark plug gap: 0.7 ~ 0.8 mm

NOTE:

Ignition timing is not adjustable

1 6. Install

• Spark plug Ø

NOTE:

Before installing a spark plug, clean the gasket surfa- ce and plug surface

IGNITION TIMING CHECK NOTE:

Prior to checking the ignition timing, check all electri- cal connections related to the ignition system. Make sure all connections are tight and free of corrosion and that all ground connections are tight.

1. Attach:

1 • Timing light Ø

Engine tachometer Ø

(to the spark plug lead)

	Timing light: 90890-03141
Engine tachometer: 90890-03113

2. Check

• Ignition timing

************************************************************ Checking steps:

• Start the engine and let it warm up for several minu- tes. Let the engine run at the specified speed.

Engine idling speed: 1,600 ~ 1,800 r/min

• Check the stationary pointer §a to verify that it is wit- hin the required firing range §b indicated on the

flywheel

a Incorrect firing range —(check the ignition system

NOTE:

Insufficient compression pressure will result in perfor- mance loss

1. Remove

• Seat and compartment

2. Check:

• Valve clearance

If not as specified, adjust

See section on VALVE CLEARANCE ADJUST- MENT

3. Start the engine and let it warm up for several minutes.

4. Turn off the engine

5. Remove:

• Spark plug
