COMPRESSION 

1. Warm up and stop engine. 

Allow the engine to warm up to normal operating temperature. 

2. Remove the surge tank. Refer to INTAKE MANIFOLD.  

3. Remove the ignition coil connectors (A) and ignition coils (B).

measure the compression pressure.

4. Remove the spark plugs. 

Using a 16 mm plug wrench, remove the 6 spark plugs. 

5. Check cylinder compression pressure. 

1. Insert a compression gauge into the spark plug hole.  

2. Fully open the throttle.  

3. After 7 times of cranking the engine, measure the compression pressure. 

4. Repeat steps (a) through (c) for each cylinder. 

Compression pressure: 

1,225 kPa (12.5 kgf/cm

2

 , 177 psi) - 200-250 RPM

 

Minimum pressure: 

1,078 kPa (11.0 kgf/cm

2

 , 156 psi)

 

5. If the cylinder compression in 1 or more cylinders is low, pour a small amount of engine oil into the 

cylinder through the spark plug hole and repeat steps (1) through (3) for cylinders with low 
compression. 



If adding oil helps the compression, it is likely that the piston rings and/or cylinder bore are 
worn or damaged.  



If pressure stays low, a valve may be sticking or seating is improper, or there may be leakage 
past the gasket.  

6. Reinstall the spark plugs.  

7. Install the ignition coil and ignition coil connectors.  

8. Install the surge tank. Refer to INTAKE MANIFOLD.  

VALVE CLEARANCE INSPECTION AND ADJUSTMENT 

1. Remove the engine cover.  

2. Remove air cleaner assembly. Refer to REMOVAL. 

NOTE:

Always use a fully charged battery to obtain engine speed of 250 
RPM or more.

NOTE:

This measurement must be done in as short a time as possible.

NOTE:

Inspect and adjust the valve clearance when the engine is cold (Engine coolant 
temperature: 20°C) and cylinder head is installed on the cylinder block.
