NOTE:
The sponge material should be cleaned every
20–40 hours. It should be cleaned and lubricat-
ed more often if the machine is operated in
extremely dusty areas. Each time air filter ele-
ment maintenance is performed, check the air
inlet to the filter case for obstructions. Check the
air filter case rubber joint to the carburetor and
manifold fittings for an air-tight seal. Tighten all
fittings securely to avoid the possibility of unfil-
tered air entering the engine.
cC
Never operate the engine with the air filter
element removed. This will allow unfiltered
air to enter, causing rapid engine wear and
possible engine damage. Additionally, opera-
tion without the air filter element will affect
carburetor jetting with subsequent poor per-
formance and possible engine overheating.

8Refill with the same type of brake fluid.
Mixing fluids may result in a harmful chemi-
cal reaction and lead to poor brake perfor-
mance.
8Be careful that water does not enter the
brake fluid reservoir when refilling. Water
will significantly lower the boiling point of the
fluid and may result in vapor lock.
8Brake fluid may deteriorate painted surfaces
or plastic parts. Always clean up spilled fluid
immediately.
8Have a Yamaha dealer check the cause if
the brake fluid level goes down.
