INSTRUMENT AND CONTROL FUNCTIONS
CAUTION:

fuel may deteriorate painted surfac-
es or plastic parts.

Recommended fuel:
UNLEADED GASOLINE ONLY
Fuel tank capacity:
20.0 L (5.28 US gal) (4.40 Imp.gal)
Fuel reserve amount:
3.5 L (0.92 US gal) (0.77 Imp.gal)
CAUTION:
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 de-
signed to use regular unleaded gaso-
line with a pump octane number
[(R+M)/2] of 86 or higher, or a research
octane number of 91 or higher. If
ECA10070
knocking (or pinging) occurs, use a
gasoline of a different brand or premi-
um unleaded fuel. Use of unleaded fuel
will extend spark plug life and reduce
maintenance costs.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that contain-
EAU13300
ing methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10%. Gasohol
containing methanol is not recom-
mended by Yamaha because it can
cause damage to the fuel system or ve-
hicle performance problems.

The fuel cock supplies fuel from the
tank to the carburetor while filtering it al-
so.
The fuel cock has three positions:
OFF
1. Pointed end positioned over "OFF"
