More frequent replacement is required if
ridden in unusually dusty or rainy areas.
· Do not clean the paper element with
compressed air.
· If the air cleaner is installed improperly,
dust may be sucked into the cylinder
directly to reduce the engine horse-
power and affect engine service life.
· Pay attention to the installation
direction during reassembly.
CYLINDER COMPRESSION
Warm up the engine before compression
test.
Remove the spark plug and insert a
compression gauge.
Open the throttle valve fully and crank the
engine with the starter motor or kick lever
for 78 seconds to test the compression.
Compression:
DA25AA,B: 13kg/cm
DA30AA,B: 16kg/cm
If the compression is low, check for the
following:
Leaky valves
Valve clearance too small
Leaking cylinder head gasket
Worn piston/cylinder
Worn piston rings
If the compression is high, it indicates that
carbon deposits have accumulated on the
combustion chamber and the piston head.
