Before operating the motorcycle:
Check the fuel tank breather/
overflow hose connection.
Check the fuel tank breather/
overflow hose for cracks or dam-
age, and replace it if damaged.
Make sure that the end of the fuel
tank breather/overflow hose is not
blocked, and clean it if necessary.
Make sure that the end of the fuel
tank breather/overflow hose is
positioned inside of the clamp.
ECA11400CAUTION:
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 sys-
tem.
Your Yamaha engine has been de-
signed to use premium unleaded
gasoline with a research octane num-
ber of 95 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.
