The valve stems are of reduced diameter to reduce resistance to the inlet mixture and to the
exhaust gases.
The inlet valves (26) and the exhaust valves (26) use identical springs. These are variable rate
springs to make the valves operate correctly.
The cam followers (25) are not adjusted using shims, this to reduce weight.
NOTE : Adjustment of valve clearances is done by replacing the existing cam followers with cam
followers of the appropriate thickness. Cam followers are available in 29 thicknesses going in inter-
vals of 0.02 mm from 5.12 mm to 5.68 mm.
