Throttle Inspection
(1) throttle
1. Check that the throttle assembly is positioned
properly and the securing bolts are tight.
2. Check for smooth rotation of the throttle (1)
from fully open to fully closed in all steering
positions. If there is a problem, see your
Honda dealer.
3. Inspect the condition of the throttle cables
from the throttle grip down to the carburetor.
If the cable is kinked or chafed, have it
replaced.
4. Check the cables for tension or stress in all
steering positions.
5. Lubricate the cables with a
commercially-available cable lubricant to
prevent premature rust and corrosion.
