Periodic Maintenance Procedures
Clutch Plates Inspection
Remove the clutch plates (see Clutch Removal in the
Visually inspect the friction and steel plates to see if they
show any signs of seizure, or uneven wear.
If any plates show signs of damage, replace the friction
plates and steel plates as a set.
Measure the thickness [A] of the friction plates with vernier
Friction Plate Thickness
2.92 ∼ 3.08 mm (0.115 ∼ 0.121 in.)
2.6 mm (0.10 in.)
If they have worn past the service limit, replace them with
Place each friction plate or steel plate on a surface plate,
and measure the gap between the surface plate [A] and
each friction plate or steel plate [B] with a thickness gauge
[C]. The gap is the amount of friction or steel plate warp.
Friction and Steel Plates Warp
Friction Plate 0.15 mm (0.0059 in.) or less
0.2 mm (0.008 in.) or less
Friction Plate 0.3 mm (0.01 in.)
0.3 mm (0.01 in.)
If any plate is warped over the service limit, replace it with
a new one.
Engine Lubrication System
Engine Oil Change
Warm up the engine thoroughly so that the oil will pick up
any sediment and drain easily. Then stop the engine.
Remove the engine oil drain bolts on the bottom of the
engine, and let the oil drain completely.
Drain Bolt (M6) [A]
Drain Bolt (M10) [B]
Hold the motorcycle upright so that the oil may drain
Replace the gaskets at the drain bolts with a new one.
After the oil has completely drained out, install the drain
bolts with the gaskets, and tighten them.
