The Vokes “Distribution Rectifier”
I recall years ago in motoring magazines, be it car or motorcycle, various devices appeared in advertisements offering claims for all types of gadgets. They all guaranteed the same results, easier starting, less carbon build up, more miles per gallon, improved acceleration and higher top speed. Recently whilst in Victoria, Rod Tingate gave me one such device together with paperwork from the manufacturer Vokes who were the makers of air cleaners for British motor cycles. The paperwork coming with this device was as follows: ‘The Vokes “Distribution Rectifier”. A further efficient contribution for the benefit of improved motoring, developed by Volkes Ltd, Pioneers of Scientific Filtration. Fitted between the intake manifold and the carburettor the “Rectifier” takes all bias out of the mixture flow and improves vaporization. Vokes Ltd Guildford, Surrey.’ Further paperwork indicates: “The Vokes Distribution Rectifier Positively Provides: Easier starting from cold. Better vaporization of the mixture. Even distribution to ALL cylinders. Smoother running. Greater flexibility and power output. Smoother torque. Better pulling at low speed in top gear. Less gear changing. Better top gear performance. Improved acceleration and fuel consumption. Increase in miles per gallon. Elimination of flat spots and stalling. “This implement as stated is fitted between the carburettor and manifold. It is very well made and for carburettors with an inch and a sixteenth venturi and two inch mounting. There is a mesh center which is concaved inwards leaving the inner nine sixteenths for the normal and regular unrestricted manner of flow. I am aware that some years ago tuners of racing sedans had gone away from polishing ports to inserting twirled metal on the walls of the intake manifolds to create a swirling gas flow into the combustion chamber. However I had not previously seen nor heard of this type of fitting for motorcycles.
