The air cleaner was located aft of the nearside rear wheel and although this was hard to reach had to be attended-to regularly if engine performance was not to suffer.

The nearside of the engine carries the generator and magneto, the carburettor and its water-heated induction pipe with a proper hot-spot and the vacuum tank on the dash.
