Valve Clearance
Camshaft, valve, valve shim and valve seat wear affect the valve clearances. The
effect of this wear is to change the clearance between the rocker and the adjustment
shim, causing engine noise and/or improper running. If the valve clearances are
incorrect, permanent damage to components in the valve train will take place and
engine performance will be affected.
Note
Valve clearance adjustment must be carried out with the engine cold.
When replacing a valve shim, always refer to the EPC.
For valve clearance specifications (see Cylinder Head and Valves).
Valve Clearance Adjustment
WARNING
Before starting work, ensure the motorcycle is stabilised and adequately
supported. This will help prevent it from falling and causing injury to the operator
or damage to the motorcycle.
Perform the following operations:
Seat - Removal
Battery - Removal
Fuel Tank - Removal
Note
Valve clearance checking and adjustment must be carried out with the engine
cold.
Remove the camshaft cover (see Camshaft Cover - Removal).
1.
Note
Removing the spark plugs reduces compression therefore allowing the engine
to be rotated freely.
Remove the spark plugs.
2.
Select a high gear and, using the rear wheel, rotate the engine until a camshaft
lobe is positioned pointing directly away from the roller on the rocker shaft.
3.
Using feeler gauges, measure and record the clearances for this pair of valves
only.
