Tips for reducing fuel
consumptionYour motorcycle’s fuel consumption
depends to a large extent on your
riding style. The following tips can help
reduce fuel consumption:l
Warm up the engine before riding.
l
Turn off the starter (choke) as
soon as possible.
l
Shift up swiftly and avoid high en-
gine speeds during acceleration.
l
Do not double-clutch or rev the en-
gine while shifting down and avoid
high engine speeds with no load
on the engine.
l
Turn off the engine instead of let-
ting it idle for an extended length
of time, i.e. in traffic jams, at traffic
lights or railroad crossings.
EAU01128
Engine break-inThere is never a more important period
in the life of your motorcycle than the
period between zero and 1,600 km. For
this reason we ask that you carefully
read the following material. Because
the engine is brand new, you must 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 which might re-
sult in excessive heating of the engine,
must be avoided.
EAU01171
0 ~ 1,000 km
Avoid operation above 1/3 throttle.
1,000 ~ 1,600 km
Avoid cruising speeds in excess of
1/2 throttle.
EC000056
CAUTION:@ After 1,000 km of operation, be sure
to replace the engine oil, oil filter
and final gear oil. @1,600 km and beyond
Proceed with normal riding.
EC000049
CAUTION:@ If any engine trouble should occur
during the break-in period, consult a
Yamaha dealer immediately. @
