Recommended fuel:REGULAR UNLEADED GASOLINE ONLY
Fuel tank capacity: 19.2 L (5.07 US gal) (4.22 Imp. gal)
Fuel reserve amount (when the fuel level warning light comes on):
4.5 L (1.19 US gal) (1.00 Imp. gal)
ECA11400
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts, such
as the valves and piston rings, as well
as to the exhaust system.Your Yamaha engine has been designed
to use regular unleaded gasoline with a
research octane number of 91 or higher.
If knocking (or pinging) occurs, use a gasoline of a different brand. Use of
unleaded fuel will extend spark plug life
and reduce maintenance costs.

Catalytic converterThis model is equipped with a catalytic
converter in the exhaust system.

The exhaust system is hot after
operation. Make sure that the exhaust
system has cooled down before
