Throttle Wire Adjustment

Throttle Wire Adjustment




1. Loosen throttle wire double nuts "A" and "B" on carburetor side.




2. With throttle drum set at "P1 " (fully-open), pull fitting "Q" at 4 kg (9 lb) in direction "T" and tighten nut "B" in direction "U".
3. Reverse nut "B" 1.0 to 1.5 revolutions in direction "T", then tighten nut "A" securely. Throttle drum should be held at "P1".




4. Ensure that throttle wire stroke "L" is within specified range between full throttle and idle.

Throttle wire stroke "L": 27.4 - 31.4 mm (1.079 - 1.236 in.)

- Adjust throttle wire stroke when throttle wire/accelerator wire is installed or after carburetor has been adjusted.
- Put marks on throttle wire to facilitate measuring wire stroke.

If throttle wire stroke is improperly adjusted, the following problems may arise.



- When full-open position "P1" of throttle drum is closer to direction "T", shift schedule will be as shown by (2) in figure at left, and kickdown range will greatly increase.
- When full-open position "P1" of throttle drum is closer to direction "U", shift schedule will be as shown by (1) in figure at left, and kickdown range will not occur.

5. After properly adjusting throttle wire, ensure the parting line is as straight as possible.
