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.

ADJUSTING THE VALVE CLEARANCE
The following procedure applies to all of the
valves.

Valve clearance adjustment should be made
on a cold engine, at room temperature.

When the valve clearance is to be measured or
adjusted, the piston must be at top dead center
(TDC) on the compression stroke.

MEASURING THE COMPRESSION
PRESSURE
The following procedure applies to all of the cyl-
inders.
Insufficient compression pressure will result in a
loss of performance.
1. Measure:

valve clearance

Adjust.
Refer to “ADJUSTING THE VALVE CLEAR-
ANCE”.
2. Start the engine, warm it up for several min-
utes, and then turn it off.
3. Remove:

ignition coils

spark plugs
Before removing the spark plugs, use com-
pressed air to blow away any dirt accumu-
lated in the spark plug wells to prevent it
from falling into the cylinders.

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
a and maximum level
mark
b.
Below the minimum level mark

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.
