Shift Fork/Gear Groove Wear Inspection
Measure the thickness of the shift fork ears [A], and measure the width [B] of the gear grooves. If the thickness of a shift fork ear is less than the service limit, the shift fork must be replaced. Shift Fork Ear Thickness Standard: 5.7 6.0 mm (0.224 0.236 in.) Service Limit: 5.6 mm ...

Valve Clearance
Valve and valve seat wear decreases valve clearance, upsetting valve timing. NOTICE If valve clearance is left unadjusted, wear will eventually cause the valves to remain partly open; which lowers performance, burns the valves and valve seats, and may cause serious engine damage. Valve cle ...

Steering Stem Bearing Lubrication
Remove the steering stem (see Stem, Stem Bearing Removal in the Steering chapter). Using a high flash-point solvent, wash the upper and lower ball bearings [A] in the cages. Wipe the upper and lower outer races which are press -fitted into the head pipe to clean off grease and dirt. V ...
