1. Closing cable
2. Throttle cam
With the throttle fully closed, ensure that
there is 2 - 3 mm of free play in the 'closing'
cable at the throttle cam attached to the
throttle bodies. This is accessible from the
right hand side of the motorcycle, below the
fuel tank (it is not necessary to remove the
fuel tank). If necessary, adjust in the same
way as the 'opening' cable (at the twist grip
end) until 2 - 3 mm of play is present.

Warning
Ensure that all the adjuster locknuts of both
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.
Check that the throttle opens smoothly,
without undue force and that it closes without
sticking.
Ride carefully to your nearest authorised
Triumph dealer and have him check the
throttle system thoroughly before riding
again.
