The SE valve opens the enriching circuit via a cable when
the choke knob on the fork top bridge is pulled.
Check for smooth choke knob operation and lubricate the
choke cable if required.
Inspect the cable for cracks which could allow moisture to
enter.
Replace the cable if necessary.

Remove the five screws and air cleaner housing cover.
Remove and clean the air cleaner element in accordance
with the maintenance schedule.
Also replace the air cleaner element any time it is exces-
sively dirty or damage.
