Note. Use the battery which is fully charged.
Warm up the engine thoroughly.
Stop the engine.
Remove:
- Seats (see Frame chapter)
- Fuel Tank (see Fuel System chapter)
- Air Cleaner Housing (see Fuel System chapter)
- Stick Coils
- Spark Plugs
Special Tool - Spark Plug Wrench, Hex 16: 57001-1262
Attach the compression gauge [A] and adapter [B] firmly into the spark plug hole.

Using the starter motor, turn the engine over with the throttle fully open until the compression gauge stops rising; the compression is the highest reading obtainable.
Special Tool
Compression Gauge: 57001-221
Compression Gauge Adapter, M10X1.0: 57001-1317
Cylinder Compression. Usable Range: 950-1450 kPa (9.7-14.8 kg/cm2, 138-210 psi) @350 r/min (rpm)
Repeat the measurement for the other cylinders.
Install the spark plugs.
Torque - Spark Plugs: 13 N·m (1.3 kg·m, 113 in·lb)
The following table should be consulted if the obtainable compression reading is not within the usable range
Problem | Diagnosis | Remedy (Action) |
Cylinder compression is higher than usable range | Carrbon accumulation on piston and in combustion chamber possibly due to damaged valve stem oil seal and/or damaged piston oil rings (This may be indicated by white exhaust smoke). | Remove the carbon deposits and replace damaged parts if necessary. |
Incorrect cylinder head gasket thickness. | Replace the gasket with a standard part. | |
Cylinder compression is lower than usable range | Gas leakage around cylinder head | Replace damaged gasket and check cylinder head warp. |
Bad condition of valve seating | Repair if necessary. | |
Incorrect valve clearance. | Adjust the valve clearance. | |
Incorrect piston/cylinder clearance | Replace the piston and/or cylinder | |
Piston seizure. | Inspect the cylinder and replace/repair the cylinder and/or piston as necessary. | |
Bad condition of piston ring and/or piston ring grooves | Replace the piston and/or the piston rings. |
