IGNITION TIMING

Your motorcycle is equipped with a capacitor discharge ignition which

consists of a magneto, an electronic control unit and a Kill-Button.

Regularly check the electrical connections for dirt or corrosion. Apply

a dielectric grease to all connectors and the high tension lead when

necessary.

Timing of the engine can only be done with a stroboscopic lamp. Although

timing marks can be verified by using a dial indicator. Static timing

figures are as follows:

250: 14°± 1, 1.07 nm (0.042in)

406: 18°± 1, 2.26 nm (0.089in)

On all machines remove the timing inspection plug from the magneto cover

and connect the timing light pickup to the high tension lead.

Point the light beam straight into the inspection hole and rev the engine

to 5000 RPM for a brief instant.

If the timing is correct the magneto cover

mark and flywheel mark will align with each other.

If timing was incorrect, remove magneto cover.

Loosen the stator retaining

screws then move the stator plate in the advance or retarded direction to

correct the misalignment.

Tighten the stator plate screws.

Start the engine to recheck the alignment of the timing marks with the

timing light.

TO CHECK CONDITION- OF SPARK PLUG

A Brownish tip reflects correct jetting and plug range.

A black insulator tip indicates a rich condition.

A grey tip warns you of too lean an operating temperature. Advanced

ignition timing, engine overheating, fuel mixture too lean, clogged

carburetor jetting, wrong spark plug heat range or a leaking seal or

gasket.
