TPS Adjustment - Carbureted Models

NOTE:  Always verify the engine idle speed is set at
engine operating temperature and the throttle cable
freeplay is set to 0.10

″ - 0.30″.

1.

Connect the TPS test tool to the TPS.

2.

Slightly loosen the screws securing the TPS to carburetor
body.

3.

Have an assistant hold the throttle flipper in the WOT
position.

4.

Turn the TPS clockwise to decrease voltage, or
counterclockwise to increase voltage.

5.

Carefully tighten the TPS screws when the WOT Vdc is
4.00Vdc.

TPS Adjustment - CFI Models - Using Digital 

Wrench

Either Digital Wrench or the TPS Test Tool can be used to see
the TPS return signal voltage, set the TPS baseline and set the
idle gap on CFI models.

To use Digital Wrench, follow these steps.

1.

Click on the TOOLBOX icon.

2.

Click on “TPS INITIALIZATION”

3.

Follow the steps and procedures displayed on the screen.

TPS Baseline Adjustment - CFI Models

NOTE: 

The TPS baseline and idle speed

adjustments must be performed whenever the TPS
is moved or replaced.

1.

Remove the drive belt, driven clutch, airbox, and adapter
plate.

2.

If the TPS requires replacement, remove the throttle body
and replace the TPS.

NOTE:  If only verifying the TPS voltage setting, the
throttle body can remain on the engine.

3.

The TPS fasteners can be accessed through a set of access
holes in the TPS guard if adjustment is required.

4.

Unplug the TPS connector (B), and connect the TPS test
tool.

NOTE: The guard may need to be “flexed” to align
the holes with the TPS fasteners.

• A = TPS Fasteners

• B = TPS Harness Connector

5.

Remove the throttle cable barrel from the throttle flipper.

6.

Loosen the idle speed screw until the screw no longer
touches the tab and the throttle plates are completely closed.

• A = Idle Speed Screw

• B  =  Lock  Nut

• C = Throttle Stop

7.

Snap throttle plates 2 to 3 times to ensure plates are
completely closed.

8.

Using the TPS test tool, verify the TPS is set to 0.70 +/- 0.01
Vdc.

9.

To adjust the TPS base-line, slightly loosen the screws, then
slowly turn the TPS clockwise or counter-clockwise to
adjust the voltage.

10. Carefully tighten the screws to 31 In.Lbs. (3.5 Nm) when

the voltage is 0.70 +/- 0.01 Vdc.

11. Open and close the throttle plate 2 - 3 times and verify the

voltage is still within specification.

TPS Idle Speed Adjustment - CFI Models

1.

Verify the TPS voltage is 0.70 +/- 0.01 Vdc with the
throttle plates closed.

2.

Slowly turn the idle speed adjustment screw (A) clockwise
until the voltage displayed on the multi meter reads 0.95 +/
- 0.1 Vdc.

3.

Carefully tighten the lock nut (B) while maintaining the
voltage setting.

4.

Reinstall the throttle cable, then install the throttle body
back on to the engine.

Throttle Plate Synchronization

The throttle plates are synchronized at the time of throttle body
manufacture. Adjustment should never be required unless it is
believed the plates are out of sync.

To adjust throttle plate synchronization, follow these steps:

1.

Perform the TPS Baseline Adjustment. The TPS must be
set to specification.

2.

Carefully back the synchronization screw out so it no
longer touches the tab, but do not remove the screw or the
spring.

3.

Verify the TPS voltage is set to 0.70 +/- 0.01 Vdc. If it is
not, re-perform the baseline adjustment.

• A = Synchronization Screw

• B = Throttle Arm Tab

• C = Screw Mount

4.

Slowly turn the synchronization screw inwards until the
instant the voltage on the multimeter changes. Back the
screw out so the voltage reads 0.70 +/- 0.01 Vdc.

NOTE:  When turning the synchronization screw, do
not push the screwdriver with enough force to move
the throttle cable cam. Doing so will affect the TPS
voltage reading on the multimeter.
