FUEL
Always use the recommended fuel as stated be-
low. Also, be sure to use new gasoline the day
of a race.
NOTICE
ECA24180
Use only unleaded gasoline. The use of lead-
ed gasoline will cause severe damage to the
engine internal parts such as valves, piston
rings, and exhaust system, etc.
TIP
Your Yamaha engine has been designed to use
premium unleaded gasoline with a pump octane
number [(R+M)/2] of 91 or higher, or a research
octane number of 95 or higher. If knocking (or
pinging) occurs, use a gasoline of a different
brand.
WARNING

• For refueling, be sure to stop the engine
and use enough care not to spill any fuel.

have cooled off.
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and that containing methanol.
Gasohol containing ethanol can be used if the
ethanol content does not exceed 10 %. Gasohol
containing methanol is not recommended by
Yamaha because it can cause damage to the
fuel system or vehicle performance problems.
