6 Use a clean paint brush to clean the bore, slots and piston of the valve.

9 Refitting is a reversal of removal, ensuring that the mating faces of the valve and air cleaner are clean.
10 On completion, start the engine and check that the idle speed is stable, and that there are no air leaks. Warm the engine up to normal operating temperature, then switch on all available electrical loads and check that the idle speed is maintained.
