Highest quality, high delivery oil pump. The precision made internals with close tolerances give a more efficient oil feed and return and also reduces oil bleed past the gears when the bike is standing for long periods of time.
Oil pump kit comes with a precision engineered oil pump with high flow delivery, and includes parts worth £42.00 ie crankshaft worm drive gear 68.0050, tab washer 67.0644, left hand lock nut 67.0643, SRM`s own designed gasket 68.0939 that improves sealing the oil pump to crankcases, and doesnt cover any of the oil feed holes allowing fulll oil flow, unlike pattern gaskets on the market, fixing bolts and instructions.
Each oil pump is individually tested for feed and return rates, and bleed test, as part of SRM`s special products quality control.
