    1. MODIFICATIONS(Compared with 1979 model EX440)

    A. ENGINEThere are no particular changes.

    B. DRIVEThere are no particular changes.

    C. CHASSIS1. Tune-up label

    (8J8-77743-00)As an aid to service. a tune-up label isattached to the drive belt guard.

    2. Throttlea. To keep the throttle cable end, which is

    held by the throttle lever, from contact-ing the throttle grip, a collar is mountedand the lever is properly curved.

    3. Spark plug holder(8G9-23885-00)For better saleability. the spark plugholder is provided as standard (whichis an option for the 1979 model).

    4. Rear bumper(8E7-77341-00 ----> 8J8-77541-00)For better strength, the pipe diameter isrncrease rom . mm 0 . mm.

    8J8-77 541 -00 can be used on both1979 and 1980 models.

    D. ELECTRICAL1. Spark plug

    (94701-00063 ----> 94701-00046)The spark plug has been changed to atype because it is more easily availablein the market and does not affect engineperformance adversely.

    B-9EV (N.G.K.) ----> B-9ES (N.G.K.)

    Lever (8J5-42138-00) and collar(90387-22726) can be used on both1979 and 1980 models.Lever (8G8-42138-00) can not be usedon the 1980 model.

    Interchangeability: Yes

    2. COl magneto(8E7-85500-10 ----> 8J7-85500-1 0)For better durability and easier service,the number of pulsers is decreased from2 to 1:

    Interchangeability: No

    For the ignition timing adjustment. referto "2. New service procedure."

  • 1980 EX440

    3. COl unit(8H6-85540-10 -+ 8J7-85540-10)Due to change in the COl magneto. thecircuit is modified.

    Interchangeability: No

    4. Main switch(898-82508-20 -+ BJ7 -82508-20)For better safety, the circuits of theheadlight, meter light and taillight aremodified so that they are turned on aslong as the engine is in operation, andtheir positions are changed.

    2. NEW SERVICEPROCEDURE

    (New service procedure applied to the 1980EX440)

    If not aligned. adjust ignition timing asfollows:

    Ignition timing (B.T.D.C.)1.6 0.1 mm (0.060 0.004 in)

    7. Check the marks on flywheel and pulserfor alignment.

    Tool No.

    90890-01195Tool name

    Dial gauge stand

    Ignition timing1. Remove the recoil starter assembly.2. Remove the right side spark plug and

    screw the dial gauge stand into thespark plug hole.

    4. Rotate the magneto flywheel unit pistonis at top-dead-center (T.D.C.)Set the zero on dial gauge face to lineup exactly with a dial gauge needle.Tighten the set screw on the dial gaugestand to secure the dial gauge assemb-ly. Rotate the flywheel back and forth tobe sure that the indicator needle doesnot go past zero.

    5. Starting at T.D.C., rotate the flywheelcounterclockwise until the dial gaugereads approximately 3-1/2 needle re-volutions before-top-dead -cente r(B.T.D.C.).

    6. Slowly turn the flywheel clockwise untilthe dial guage reads specified ignitiontiming.

    a. Loosen the pulser set screws and turn

    achieved.

    NOTE: --------------'If the marks can not be aligned by this ad-justment. remove the flywheel rotor andturn the base (stator) assembly.
