each relative cylinder.
The marks (C) V1 - V5 - V3 - V6 - V2 - V4 correspond to the recommended exhaust valve clearances for each relative cylinder.
The marks (B) or (C) must be positioned between the marks (A) to make the correct adjustment.
Adjustment of inlet valves
Measure the valve clearances using feeler gauges.
See pages .
Loosen the locknut and the adjuster.
Adjust the clearance between the rocker arm and the valve yoke by means of screw.
Tighten the locknut to torque while holding the adjuster.
See pages .
Make a mark on the rocker arm when adjustment is finished.
Perform the same operation on all the other cylinders.

8 / 12
Check the clearance between the valve yoke and the exhaust rocker arm piston. Turn the piston to ensure that it is properly seated in its housing.
Use a feeler gauge corresponding to the recommended clearance.
See pages .
In the event of rocker arm play or sticking, make the check with a thicker or thinner feeler gauge in order to determine the thickness of the new adjusting
shim.

9 / 12
In the event of incorrect clearances.
Remove bolt.
Remove adjusting shim .
Hold the caliper in place when unbolting.
Andrew Burrows Rocker arms / Adjustment 03/02/16
10 / 12
Note down the thickness X engraved on adjusting shim.
Determine the thickness of the new adjustment shim, in order to obtain the recommended clearance.
See pages .
You can superimpose a maximum of 2 adjusting shims, provided that they have the same thickness. Adjusting shims are available with thicknesses of
0.05 by0.05 mm.
Andrew Burrows Rocker arms / Adjustment 03/02/16

Fit shim.
Fit bolt.
Tighten to torque.
See pages .
Hold the caliper in place when tightening.
Again check the clearance between the valve yoke and the arm piston.
Make a mark on the rocker arm when adjustment is finished.
Perform the same operation on all the other cylinders.
