Carburetor Adjustments

Throttle Operation - All Models

Check for smooth throttle opening and closing in all han-
dlebar positions. Throttle lever operation should be
smooth and lever must return freely without binding.
1. Place the gear selector in neutral.
2. Set parking brake.
3. Start the engine and let it idle.
4. Turn handlebars from full right to full left. If idle speed
increases at any point in the turning range, inspect
throttle cable routing and condition.
5. Replace the throttle cable if worn, kinked, or damaged.

Choke (Enricher) Adjustment

With the choke control toggle flipped to the full off position,
the choke plunger must be seated on the fuel passage way
in the carburetor. If the plunger is not seated on the fuel
passage way inside the carburetor (not enough cable free-
play), the engine will flood or run too rich, causing plug foul-
ing and poor performance. (Ill 1.)
If cable slack is excessive, the choke fuel passage will not
open far enough, which may cause cold starting difficulty.
Also, the half-choke position used for intermittent applica-
tions will not function properly.
1. Flip choke toggle to full off position.
2. Slide boots (C) off choke cable adjuster and lock nut. (Ill. 2)
3. Loosen adjustment locknut (A) on cable sleeve (in-line
adjusters) or on carburetor.
4. Turn cable sleeve adjusting nut (B) clockwise on
carburetor until 1/4" (6 mm) or more choke toggle free
play is evident.
5. Turn cable sleeve adjusting nut counterclockwise until
toggle has zero free play, then rotate it clockwise until
1/8"-1/4" (3-6 mm) toggle free play is evident.
6. Tighten locknut (A).
7. Slide boots back over cable adjuster sleeve until they
touch at the middle point of the sleeve (in-line
adjusters) or until seated fully over adjuster.
