Cylinder compression — check (Honda XRV750 Africa Twin)

0

Non-scheduled maintenance

1. Among other things, poor engine performance may be caused by leaking valves, incorrect valve clearances, a leaking head gasket, or worn pistons, rings and/or cylinder walls. A cylinder compression check will help pinpoint these conditions and can also indicate the presence of excessive carbon deposits in the cylinder heads.

2. The only tools required are a compression gauge and a spark plug wrench. A compression gauge with a threaded end for the spark plug hole is preferable to the type which requires hand pressure to maintain a tight seal. Depending on the outcome of the initial test, a squirt-type oil can may also be needed.

3. Make sure the valve clearances are correctly set (see Section 16) and that the cylinder head nuts are tightened to the correct torque setting (see Chapter 2).

4. Refer to Fault Finding Equipment in the Reference section for details of the compression test. Refer to the specifications at the beginning of the Chapter for compression figures.
