Note: The throttles cannot be balanced using equipment to measure vacuum in each throttle. Instead, the Triumph diagnostic software must be used.
1. Remove the rider's seat' (see page 16-13).
2. Remove the fuel tank (see page 10-91) and place on a suitable support, close to the motorcycle.
3. Remove the airbox (see page 10-98).
Warning: If the engine has recently been running, the components beneath the fuel tank may be hot to the touch.
4. Turn the ignition to the 'OFF' position.
5. Using the extension cable T3880123, carefully connect the fuel pump connection on the main harness to the fuel tank. Connect the other end of the harness extension to the motorcycle main harness.
6. Select the fuel pressure gauge adapter marked 'B' from service tool T3880001.
Warning: Always us the correct fuel pressure gauge adapter (adapter 'B' for Tiger 800 and Tiger 800XC). Use of an incorrect adapter will result in a fuel leak. A fuel leak can result in a fire causing damage to property and injury to persons.
7. Connect the adapter hose to the fuel pump plate outlet as shown in the illustration below.
1. Adaptor hose 'B'; 2. Fuel pump plate outlet; 3. Tool T3880123
8. Connect the fuel hose to the adaptor hose as shown in the illustration below.
1. Motorcycle fuel hose; 2. Adaptor hose 'B'; 3. Fuel purnp connection; 4. Wiring extension T3880123; 5. Fuel pump connection; 6. Fuel pump plate outlet
9. Attach exhaust extraction hoses to the silencer.
10. Attach the Triumph diagnostic tool to the dedicated plug, refer to the Triumph Diagnostic Tool User Guide. Start the engine, and allow to idle.
11. On the diagnostic software navigate to 'ADJUST TUNE'.
12. Select 'BALANCE THROTTLES'.
13. Click the Adjust button.
Adjust Tune Procedure
Adjust the throttle balance as described in the service manual until balanced.
Press cancel to cancel the adjustment process Press OK to finish.
Throttle Status: | Throttles Balanced |
Cylinder 1 MAP Pressure: | 480 mmHg |
Cylinder 2 MAP Pressure: | 481 mmHg |
Cylinder 3 MAP Pressure: | 480 mmHg |
Adjusting parameter - Balance Throttles
Balance Throttles Screen
Note: The balance throttle screen will show the vacuum value of each throttle in mm/Hg. In addition, when the throttles are balanced to an acceptable range of each other the word 'THROTTLES BALANCED' in green text will appear on the right of the screen. At this point, no further adjustment is necessary or productive.
- If the throttles are not balanced to each other the word 'THROTTLES UNBALANCED' in red text will appear on the right of the screen. At this point adjustment will be necessary.
- The adjusters operate on the outer cylinders only (cylinders 1 and 3). The centre throttle (cylinder 2) adjustment is fixed, this being controlled by the idle speed control stepper motor. Note that the centre reading will alter slightly as the two outer cylinders are adjusted.
- DO NOT attempt to adjust the centre throttle stop screw, located below the idle stepper motor. The stop screw is set at the factory during manufacture, and must not be adjusted.
14. Using the throttle adjusters, make adjustments to the two outer cylinders until the word 'THROTILES BALANCED' in green text appears.
1. Adjusters
15. When balanced, stop the engine and disconnect the diagnostic tool.
16. Disconnect the fuel pressure gauge adapter and wiring extension.
17. Refit the airbox (see page 10-101).
18. Refit the fuel tank (see page 10-92).
19. Remove the exhaust extraction hoses from the silencer.
