2-26 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
If it cannot be done, loosen the locknut [A] at the middle
of the clutch cable, and turn the adjusting nut [B] so that
the clutch lever has 8 ∼ 13 mm (0.3 ∼ 0.5 in.) of play.
After the adjustment is made, tighten the locknut, and
start the engine and check that the clutch does not slip
and that it release properly.
Clutch Plates Inspection
Remove the clutch plates (see Clutch Removal in the En-
gine Right Side chapter).
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
If they have worn past the service limit, replace them with
Friction Plate Thickness
2.92 ∼ 3.08 mm (0.115 ∼ 0.121 in.)
2.6 mm (0.10 in.)
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.
If any plate is warped over the service limit, replace it with
a new one.
Friction and Steel Plates Warp
Friction Plate Not more than 0.15 mm (0.0059 in.)
Not more than 0.2 mm (0.008 in.)
Friction Plate 0.3 mm (0.01 in.)
0.3 mm (0.01 in.)
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.
