                                                               Timing Hole Cap
 IGNITION TIMING
 The CDI unit is not adjustable. If the
   ignition timing is incorrect, check the
   ignition system. ( 15-5)

 Remove the right of the fan cover.




                                                    Timing Light
 Check the ignition timing with a timing light.
 When the engine is running at idle speed, the
 ignition timing is correct if the "F" mark on
 the flywheel aligns with the index mark on
 the crankcase.




 Also use a timing light to check the advance.
 Raise the engine speed to 4,000rpm and the
 index mark on the crankcase cover should be
 aligned with the advance mark on the
 flywheel.


 CYLINDER COMPRESSION
 Warm up the engine before compression test.
 Remove the met-in box and center cover.
 ( 2-3)
 Remove the spark plug.
 Insert a compression gauge.
 Open the throttle valve fully and push the
 starter button to test the compression.          "F" Mark                   Advance Mark

                                                                         Compression Gauge
 Compression:    16kg/cm2rpm
 If the compression is low, check for the
 following:
 Leaky valves
 Valve clearance to small
 Leaking cylinder head gasket
 Worn piston rings
 Worn piston/cylinder
 If the compression is high, it indicates that
 carbon deposits have accumulated on the
 combustion chamber and the piston head.
