Finally us BSA A50 & A65 owners have a choice of 2 new high delivery oil pumps to choose from. SRM which is CNC machined from billet alloy and Hepolite (England) which is CNC machined from cast iron. Both are wonderful upgrades from any original BSA oil pump.

When installing a new high delivery, either SRM or Hepolite you are ensuring that your engine will be getting the maximum oil flow and oil pressure to all the critical parts of your engine, such as the plain bearing, rod bearings, etc. Oil pumps can also solve wet sumping issues

Both oil pumps (your choice) will fit all BSA A50 & A65 models (Thunderbolt, Firebird Scrambler, Lightning, Cyclone, Spitfire, Royal Star, etc) from 1962-1972. Check your parts book to ensure that this pump will work for your application.
