Fuel Hose and Connection Inspection

If the motorcycle is not properly handled, the inside the
fuel line can cause fuel to leak [A].
Check the fuel hose.
Replace the fuel hose if any fraying, cracks [B], bulges [C]
or ozone cracks [D] are noticed.
Check that the hose [A] are securely connected and
clamps [B] are tightened correctly.
Route the hose according to Cable, Wire, and Hose Rout-
ing section in the Appendix chapter.
Avoid sharp bending, kinking, flattening or twisting, and
route the fuel hose with a minimum of bending so that the
fuel flow will not be obstructed.
Replace the hose if it has been sharply bent or kinked.

Throttle Grip (Throttle Cable) Free Play Inspection

Check throttle grip free play by lightly turning the throttle
grip [A] back and forth [B].
Throttle Grip Free Play
2 ∼ 3 mm (0.08 ∼ 0.12 in.)
Standard:
If the free play is improper, adjust the throttle cable.
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.

cable.

tle grip plenty of play.
