- Check that the throttle cable is able
to move the correct distance and
that its operation does not become
blocked or stiff at any point in the
movement.
- Adjust the ply on the throttle control
on the handlebar by tightening or
slackening the throttle cable sleeve
tensioner located beside the throttle
twist grip control until a play of 3 to
5 mm is obtained.
- Remove the right hand side body
work cover in order to gain access
to the air filter cover, withdraw the
air filter cover. Withdraw the air filter
foam, and wash it in soap and
water, then squeeze out and dry
thoroughly. Once dry soak it in spe-
cial air filter oil, and reinstall.
- Start the engine and warm it up
slightly.
- Proceed to adjust the idle speed,
using the following procedure:
- Turn the slide valve rest stop screw
until the engine does not stall (scre-
wing in).
- Screw the minimum circuit air adjus-
ter screw fully home, but without for-
cing it. Then unscrew 1 1/2 turns.
Start the engine again if it has sta-
lled during this operation.
4-6
- Turn the slide valve rest stop screw again, slowly
screwing in and out, until a stable idle speed of 1,800
± 50 rpm is obtained (use an external rev counter for
this purpose).
- Rev up the engine fast using the throttle control, and
check that the engine accelerates and decelerates
brilliantly and fast, with no soft spots. If this is not
obtained, repeat the carburettor adjustment procedu-
re again from the first step.
- For models with a carburettor heater, proceed accor-
ding to the following information in order to achieve
proper operation.
