Special Tools - Compression Gauge, 20 kgf/cm²: 57001-221 Compression Gauge Adapter, M10 × 1.0: 57001-1601 L-Shape Hose [C]: 57001-1606
Cylinder Compression
Usable Range: 1 099 1 668 kPa (11.2
17.0 kgf/cm²,
159 242 psi) at 320 r/min (rpm)
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 | Carbon 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. |
Stick Coil Inspection
Remove the stick coils (see Stick Coil Removal).
Measure the primary winding resistance [A] as follows.
Connect the hand tester between the coil terminals.
Set the tester to the × 1 Ω range, and read the tester.
Measure the secondary winding resistance [B] as follows.

KIBS Hydraulic Unit Inspection
Remove the KIBS hydraulic unit (see KIBS Hydraulic Unit
Removal).
Visually inspect the connector terminals [A].
Replace the KIBS hydraulic unit or main harness if either
of the terminals are cracked, bent, or otherwise damaged.
If the KIBS hydraulic unit connector is clogged with mud
