Maintenance and Adjustment
If there is an incorrect amount of free play,
Triumph recommends that you have
adjustments made by your authorized
Triumph dealer. However, in an emergency,
throttle adjustment may be made as follows:
1. Opening cable adjuster
2. Closing cable adjuster
3. Closing cable – free play
measurement point
4. Opening cable – free play
measurement point
Adjustment
Remove the seat.
Disconnect the battery, negative (black) lead
first.
Remove the fuel tank and airbox.
Release the locknut on the 'opening' cable
adjuster.
Rotate the 'opening' cable adjuster at the
twist grip end such that it has an equal
amount of adjustment in each direction.
Rotate the 'opening' cable adjuster at the
throttle body end of the cable to give
0.08 - 0.12 in (2 - 3 mm) of play at the twist
grip. Tighten the locknut.
Make any minor adjustments as necessary to
give 0.08 - 0.12 in (2 - 3 mm) of play using
the adjuster near the twist grip end of the
cable. Tighten the locknut.
With the throttle fully closed, ensure that
there is 0.08 - 0.12 in (2 - 3 mm) of free play
in the 'closing' cable at the throttle cam
attached to the throttle bodies. If necessary,
adjust in the same way as the 'opening' cable
until 0.08 - 0.12 in (2 - 3 mm) of play is
present.
Re-install the fuel tank and airbox.
Reconnect the battery, positive (red) lead first.
Re-install the seats.
Check that the throttle opens smoothly,
without undue force and that it closes without
sticking.
Ride carefully to your nearest authorized
Triumph dealer and have them check the
throttle system thoroughly before riding
again.

Warning
Ensure that all the adjuster locknuts of all
cables are tightened, as a loose locknut
could result in a sticking throttle.
An incorrectly adjusted, sticking or stuck
throttle can lead to loss of motorcycle
control and an accident.
