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. |
Rocker Arm Installation
Install the both rocker arms [A] so that their marks [B] face
left side.
Replace the tie-rod nut, rear shock absorber nut and
rocker arm nut with new ones.
Apply grease to the inside of the oil seals.

Drive Chain Slack Inspection
NOTE
Check the slack with the motorcycle setting on its sidestand.
Clean the chain if it is dirty, and lubricate it if it appears
dry.
Check the wheel alignment (see Wheel Alignment Inspection).
Rotate the rear wheel to find the position where the chain
is tightest.

Battery Maintenance
It is the owner’s responsibility to keep
the battery fully charged. Failure to do
so can lead to battery failure and leave
you stranded.
If you are riding your vehicle infrequently,
inspect the battery voltage
weekly using a voltmeter. If it drops
below 12.8 volts, the battery should be
