Measure the resistance between the Blue and Black wire terminals of the sensor side connector.
STANDARD: 4 - 6 kfl (20X/68 F)
Calculate the throttle position sensor resistance at idle speed using the equation below.
Ax (0.13-0.15) = В
A: Blue and Black wire terminals resistance B: Throttle position sensor resistance at idle speed
(Ex.)
If the Blue and Black wire terminals resistance is 5 кЛ, then the throttle position sensor (Yellow - Black) resistance at idle speed is:
5 kfl x (0.13 - 0.15) = 650 - 750 П

Adjust the throttle position sensor position so the resistance between terminals Yellow and Black is resistance calculated. 05, 06: Tighten the torx screw to the specified torque. TORQUE: 3.4 N m (0.3 kgf m, 2.5 Ibf ft) After ’06: Tighten the bolt to the specified torque. TORQUE: 3.4 N m (0.3 kgf m, 2.5 Ibf ft) Connect the throttle position sensor connector. Install the carburetor (page 6-24). |

NOTE: • The pilot screw is factory pre-set and no adjustment is necessary unless the pilot screw is replaced. • Use a tachometer with graduations of 50 rpm or smaller that will accurately indicate a 50 rpm change. BEST IDLE ('05, '06: 49 States and Canada type only) 1. Turn the pilot screw clockwise until it seats lightly, then back it out the specified number of turns. |

TOOL: Pilot screw wrench |
STANDARD OPENING: 1-1/4 turns out
2. Warm up the engine to operating temperature. Ride the motorcycle for approximately 10 minutes.

2. Warm the engine up to operating temperature. Stop and go riding for 10 minutes is sufficient.
3. Stop the engine and connect a tachometer according to its manufacturer's instruction.
4. Disconnect the PAIR control valve vacuum hose and plug it to keep air from entering, then connect the vacuum pump to the PAIR control valve vacuum hose joint.
5. Apply the specified vacuum to the PAIR control valve vacuum hose more than 56 kPa (420 mmHg).
6. Start the engine and adjust the idle speed with the throttle stop screw.

8. Lightly open the throttle 2 or 3 times, then adjust the idle speed with the throttle stop screw.
9. Turn the pilot screw in until the engine speed drops by 50 rpm.
10-Turn the pilot screw counterclockwise to the final opening from the position obtained in step 9.
FINAL OPENING: 1/2 turns out
11. Remove the plug from the vacuum hose, then disconnect the vacuum pump and connect the vacuum hose to the PAIR control valve.
12. Readjust the idle speed with the throttle stop screw.
IDLE SPEED: 1,700 ± 100 rpm
Disconnect the tachometer.
