CARBURETOR IDLING
● Stand the vehicle on the main stand.
● Heat the engine to make accurate idling inspection and
adjustment.
● Verify all engine adjustments satisfy specifications.
Make adjustments, if necessary.
● Turn the throttle stop screw and make adjustments to
prescribed idling speed.
AIR SCREW ADJUSTMENT
•The air screw is factory pre-set. Adjustment is not
necessary unless the carburetor is overhauled or a
new air screw is installed.
•Tightening the air screw against its seat will damage
the seat.
● Turn the air screw clockwise until it seats lightly then
back it out to the specification given. This is an initial
setting prior to the final air screw adjustment.
● Rev the engine up slightly from the idle speed and
make sure that engine speed rises and returns smoothly.
● Adjust by turning the air screw in or out within a 1/4
turn if necessary. If the engine cannot be adjusted by
turning the air screw within a 1/4 turn, check for other
engine problems.
•Excessive air screw adjustment may cause the engine
sticking and deteriorate the starting performance.
BRAKE FLUID
● Remove the brake fluid cover.
● Check the oil level inside the front brake reservoir. If
the oil level is near the lower limit line, remove the
reservoir diaphragm and fill DOT 3 and DOT 4 brake
fluid to the top limit line.
● If the brake fluid reaches the lower limit line, check the
entire brake system for leaks.
•Brake fluid will damage painted, plastic or rubber
parts.
•Mixing incompatible fluids can impair braking
efficiency.
•Foreign materials can clog the system, causing a
reduction or complete loss of braking ability.
•A leak in the brake system can lead to reduced
braking effiency and possible loss of braking ability.
