Periodic Maintenance Procedures
Fuel Hose and Connection Inspection
The fuel hoses are designed to be used throughout the
motorcycle's life without any maintenance, however, if the
motorcycle is not properly handled, the inside the fuel line
can cause fuel to leak [A] or the hose to burst.
Check the fuel hose.
Replace the fuel hose if any fraying, cracks [B], bulges [C]
or ozonic cracks [D] are noticed.
Check that the hose [A] is securely connected and clamps
[B] are tightened correctly.
When installing the fuel hose, avoid sharp bending, kink-
ing, flattening or twisting, and route the fuel hose with a
minimum of bending so that the fuel flow will not be ob-
Replace the hose if it has been sharply bent or kinked.
Throttle Cable Inspection
Check throttle grip free play [A] by lightly turning the throt-
tle grip [B] back and forth.
If the free play is improper, adjust the throttle cable.
Throttle Grip Free Play
Standard: 2 ∼ 3 mm (0.08 ∼ 0.12 in.)
Check that the throttle grip moves smoothly from full open
to close, and the throttle closes quickly and completely in
all steering positions by the return spring.
If the throttle grip does not return properly, check the throt-
tle cable routing, grip free play and cable damage. Then
lubricate the throttle cable.
Run the engine at the idle speed, and turn the handlebar
all the way to the right and left to ensure that the idle speed
does not change.
If the idle speed increase, check the throttle cable free
play and the cable routing.
Throttle Cable Adjustment
Loosen the locknut [A] at the upper end of the throttle
Screw throttle cable adjuster [B] until 2 ∼ 3 mm (0.08 ∼
0.12 in.) of throttle grip free play is obtained.
Tighten the locknut.
