CAUTION:_ Use only unleaded gasoline. The
use of leaded gasoline will cause se-
vere damage to internal engine
parts, such as the valves and piston
rings, as well as to the exhaust sys-
tem. _Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use
of unleaded fuel will extend spark plug
life and reduce maintenance costs.
EAU04484
Fuel cock This motorcycle is equipped with a
negative pressure fuel cock. The fuel
cock supplies fuel from the tank to the
carburetor while also filtering it.
The fuel cock lever positions are ex-
plained as follows and shown in the il-
lustrations.
ON
With the fuel cock lever in this position,
fuel flows to the carburetor when the
engine is running. Turn the fuel cock le-
ver to this position when starting the
engine and riding.RES
This indicates reserve. With the fuel
cock lever in this position, the fuel re-
serve is made available. Quickly turn
the fuel cock lever to this position if you
run out of fuel while riding, otherwise
the engine may stall and will have to be
primed (see “PRI”). After turning the
fuel cock lever to “RES”, refuel as soon
as possible and be sure to turn the fuel
cock lever back to “ON”! Recommended fuel:

Tips for reducing fuel
consumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:

Thoroughly warm up the engine.


Turn the starter (choke) off as
soon as possible.


Shift up swiftly, and avoid high en-
gine speeds during acceleration.


Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the engine.


Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
EAU01128
Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1,600 km. For this rea-
son, you should read the following ma-
terial carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1,600 km. The various parts in the en-
gine wear and polish themselves to the
correct operating clearances. During
this period, prolonged full-throttle oper-
ation or any condition that might result
in engine overheating must be avoided.
EAU03845*
0–1,000 km
Avoid prolonged operation above
1/3 throttle.
1,000–1,600 km
Avoid prolonged operation above
1/2 throttle.
ECA00080*
CAUTION:_ After 1,000 km of operation, the en-
gine oil must be changed, and the
oil filter element replaced. _1,600 km and beyond
The vehicle can now be operated nor-
mally.
EC000049
CAUTION:_ If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle. _

Periodic maintenance and lubrication chart
NOTE:_

The annual checks must be performed every year, except if a kilometer-based maintenance is performed instead.


From 50,000 km, repeat the maintenance intervals starting from 10,000 km.


Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and techni-
cal skills.

CAUTION:Be sure to use motor oils that do not contain anti-fric-
tion modifiers. Passenger car motor oils (often labeled
“ENERGY CONSERVING II”) contain anti-friction addi-
tives which will cause clutch and/or starter clutch slip-
page, resulting in reduced component life and poor
engine performance.
