Compression Pressure Check
B940H21404002
The compression pressure reading of a cylinder is a
good indicator of its internal condition.
The decision to overhaul the cylinder is often based on
the results of a compression test. Periodic maintenance
records kept at your dealership should include
compression readings for each maintenance service.
NOTE
• Before checking the engine for
compression pressure, make sure that the
cylinder head nuts are tightened to the
specified torque values and the valves are
properly adjusted.
• Make sure that the battery is in fully-
charged condition.
1) Warm up the engine.
2) Lift and support (for #1 cylinder) the fuel tank. Refer
to “Fuel Tank Removal and Installation in Section 1G
(Page 1G-9)”.
3) Remove the right frame head cover (for #2 cylinder).
Refer to “Exterior Parts Removal and Installation in
Section 9D (Page 9D-5)”.
4) Remove the all spark plug caps and spark plug (1).
Refer to “Spark Plug Cap and Spark Plug Removal
and Installation in Section 1H (Page 1H-4)”.
5) Install the compression gauge and adaptor in the
spark plug hole. Make sure that the connection is
tight.
