Throttle Grip and Cables

Throttle Grip Play Inspection/Adjustment

• Refer to the Throttle Control System Inspection in the Periodic Maintenance chapter.

Choke Lever Operation

ODo not use the choke lever except when the engine has a starting difficulty like in cold weather (10 °C, 50 °F or below) or at high altitude. The DFI system has an automatic choke system, using a water temperature sensor, and an atmospheric pressure sensor, which provide startability.

NOTE

OPull [A] the choke lever fully when using. The choke doesn't work with the lever knob halfway.

Front[B]

OWhen flooded, do not crank the engine with the throttle fully opened like a carburetor. This promotes engine flooding because more fuel is supplied automatically by the DFI system.

Choke Lever Play Inspection

• Push the choke lever [A] fully and ensure by your finger that the choke cam [B] has the specified play.

Choke Lever Free Play Standard: 0 ~ 0.5 mm (0 ~ 0.02 in.)

• Pull [C] the choke lever fully and ensure that the choke cam turns the choke link [D].

*If the free play is incorrect, adjust the choke cable.

Choke Lever Play Adjustment

• Remove the fuel tank (see this chapter).

• Loosen the locknut [A], and turn the adjuster [B] until the cable has the proper amount of free play.

• Tighten the locknut against the adjuster securely.

Cable Removal/Installation

• Refer to the Throttle Assy section in this chapter for removal/installation of the throttle cables and choke cable.

Cable Lubrication and Inspection

• Refer to the General Lubrication in the Periodic Maintenance Chapter.

Idle Speed Inspection/Adjustment

• Refer to the Idle Speed Inspection in the Periodic Maintenance chapter.

Throttle Bore Cleaning

• Refer to the Throttle Control System Inspection in the Periodic Maintenance chapter.

Engine Vacuum Synchronization

Inspection/Adjustment

• Refer to the Engine Vacuum Synchronization Inspection in the Periodic Maintenance chapter.

High Altitude Performance Adjustment

• Any modification is not necessary in this model since the atmospheric pressure sensor senses atmospheric pressure change due to high altitude and the ECU compensates the change.
