• If the throttle grip does not return properly, have the throttle control system checked by an authorized Kawasaki dealer.
• Check the throttle grip free play by turning back and forth.

3. Adjuster

• If the throttle cable cannot be adjusted with the adjuster at the upper end of the throttle cable, further adjustment of the throttle cables should be done by an authorized Kawasaki dealer.
• With the engine idling, turn the handlebars to each side. If handlebars movement changes the idle speed, the throttle cables may be improperly adjusted or incorrectly routed, or they may be damaged. Be sure to correct any of these conditions before idling.

WARNING

Operation with improperly adjusted, incorrectly routed, or damaged cables could result in an unsafe riding condition. Be sure the control cables are adjusted and routed correctly, and are free from damage.

Idle Speed

This motorcycle is equipped with the idle speed control valve. So adjustment of the idle speed is not necessary on this motorcycle. If the idle speed is disturbed, inspection of the idle speed control should be done by an authorized Kawasaki dealer.

Idle Speed

1 600 +-100 r/min (rpm)

Brakes

If you feel there is something wrong when applying the brakes, have the brake system checked by an authorized Kawasaki dealer immediately.

WARNING

Air in brake line can make the brake feel mushy or soft. This may cause reduced braking performance or brake failure and result in an accident. If brake lever travel is excessive or the brake feels mushy, have an authorized Kawasaki dealer inspect it immediately.

Brake Fluid Level Inspection

• With the brake fluid reservoir held horizontal, the brake fluid level must be above the lower level line.

2. Lower Level Line

• If the fluid level is lower than the lower level line it may indicate that the fluid is leaking. In this case, have the brake system inspected by an authorized Kawasaki dealer.

Brake Pad Wear Inspection

Inspect the brakes for wear. For each front and rear disc brake caliper, if the thickness of either pad lining is less than below table, replace both pads in the caliper as a set. Pad replacement should be done by an authorized Kawasaki dealer.
