HOW TO ADJUST BREAKER POINT GAP AND IGNITION TIMING

Breaker Point Gap Adjustment

Adjust breaker point gap, before performing the ignition adjustment.

    1)Remove the point and dynamo covers. Turn the crankshaft with the pin spanner                   provided as a service tool until the breaker arm slipper  is on the highest point of cam            lobe.

2. cam

          2)Measure point gap using a thickness gauge. The gap should be 0.3-0.4mm                             (0.0012- 0.016).

          3)If it is necessary to make adjustment, loosen the breaker arm retaining screws,                      insert a screwdriver in the adjusting screw slot, and pry to adjust to the above                         value. Retighten the screw securely after setting is made.

            4) Check the ignition. When the point contact surfaces are pitted or dirty, grand                          contacts with a point file or oil stone to remove transfer or contamination. If the                     metal build-up on the point is greater than 0.5mm (0.02 in.), it should be                                 replaced.

IGNITION TIMING ADJUSTMENT

    1) Disconnect the contact breaker cord (green cord) at the connector and connect a 12V-            3W lamp across the line.

                                            1. "F" aligning mark

                                            2. Breaker arm spring

                                            3. Ground to earth

                                            4. Bulb

         

       2) Set the combination switch to "ON" position.

       3) Turn the rotor slowly until the lamp goes out and check the position of "F" mark on                the L. crankcase. If they are in line, the ignition timing is correct.

                                            2. Breaker arm spring

                                            3. Ground to earth

                                            4. Bulb

        4) If ignition timing is required for adjustment, loosen two base plate mounting screws

             and move the base plate. Turning the base plate clockwise will retard the timing and              counter clockwise will advance it. Tighten the screw after adjustment is made.
