Checking fuel filter
Correct idling speed inspection is only possi-
ble if the engine is fully warmed up. If not
warmed up fully, the idle speed will measure
higher than normal. If you have difficulty ver-
ifying the idle speed, or the idle speed re-
quires adjustment, consult a Yamaha dealer
or other qualified mechanic.
Check the fuel filter periodically. The fuel fil-
ter is a one piece, disposable type. If foreign
matter is found in the filter, replace it. For re-
placement of the fuel filter, consult your
Yamaha dealer.
2.
Verify whether the idle speed is set to
specification. For idle speed specifica-
tions, see page 34.
