Air filter
This model’s air filter is equipped with a disposable oil-coated paper element, which must not be
cleaned with compressed air to avoid damaging it.
The air filter element needs to be replaced more frequently when riding in unusually wet or dusty areas.
Hydraulic brake service
After disassembling the brake master cylinders and calipers, always change the fluid. Regularly
check the brake fluid levels and fill the reservoirs as required.
Every two years replace the internal components of the brake master cylinders and calipers, and
change the brake fluid.
Replace the brake hoses every four years and if cracked or damaged.

CHECKING THE ENGINE OIL LEVEL
1. Stand the motorcycle on a level surface.
Place the motorcycle on a suitable stand.
Make sure the motorcycle is upright.
2. Start the engine, warm it up for several min-
utes, and then turn it off.
3. Check:
engine oil level
The engine oil level should be between the
minimum level mark

MEASURING THE ENGINE OIL PRESSURE
1. Check:
engine oil level
Below the minimum level mark
a Add the
recommended engine oil to the proper level.
2. Start the engine, warm it up for several min-
utes, and then turn it off.
When the engine is cold, the engine oil will
have a higher viscosity, causing the engine
oil pressure to increase. Therefore, be sure
to measure the engine oil pressure after
warming up the engine.
3. Remove:
bottom cowlings
Refer to “COWLINGS”.

NOTE:
EAS00115
CHECKING THE BRAKE FLUID LEVEL
1. Stand the motorcycle on a level surface.
Place the motorcycle on a suitable stand.
Make sure the motorcycle is upright.
2. Check:
brake fluid level
Below the minimum level mark
a Add the
recommended brake fluid to the proper level.
Recommended brake fluid
DOT 4
AFront brake
BRear brake
Use only the designated brake fluid. Other
brake fluids may cause the rubber seals to
deteriorate, causing leakage and poor
brake performance.
Refill with the same type of brake fluid that
is already in the system. Mixing brake
fluids may result in a harmful chemical
reaction, leading to poor brake perfor-
mance.
When refilling, be careful that water does
not enter the brake fluid reservoir. Water
will significantly lower the boiling point of
the brake fluid and could cause vapor lock.
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean
up any spilt brake fluid immediately.
In order to ensure a correct reading of the brake
fluid level, make sure the top of the brake fluid
reservoir is horizontal.
