GP Type

Amal matchbox remote reservoir

Originally the GP carburettor was intended for track use, but it also found its way on to a few BSA production bikes for road use as standard equipment. The Amal GP carburettor has only recently become available, in a 1&1/2" size only. They are supplied with a "matchbox" type remote reservoir (shown).

The table below shows some of the original application details for your reference.
