Oxygen Sensor Installation (Equipped Models)
NOTICE Never drop the oxygen sensor [A] especially on a hard surface. Such a shock to the unit can damage it. Do not touch the sensing part [B] to prevent oil contact. Oil contamination from hands can reduce sensor performance. Tighten: Torque - Oxygen Sensor: 25 N·m (2.5 kgf·m, 18 ...

Hub Bearing Inspection
Since the hub bearings are made to extremely close tolerances, the clearance can not normally be measured. NOTE Do not remove any bearings for inspection. If any bearings are removed, they will need to be replaced with new ones. Turn each bearing in the hub back and forth [A] while checki ...

Cylinder (Upper Crankcase) Wear Inspection
Split the crankcase (see Crankcase Splitting). Remove the pistons (see Piston Removal). Assemble the cylinder (upper crankcase) [A], the cylinder head [B] and the cylinder head gasket [C]. Tighten the cylinder head bolts (see Cylinder Head Installation in the Engine Top End chapter). ...
