Motorcycle Oil Pumps

Jims brand Oil Pumps for Shovelhead & Big Twin Evolution Motorcycles.

BILLET OIL PUMPS FOR BIG TWIN -Jims

Beautiful yes, but most important feature about these JIMS Flow Pro 1 oil pumps is the fact that they are designed to scavenge oil quicker from the lower end than the OE oil pump. Less oil on the flywheels and rotating parts equates into limited oil drag resulting into free horsepower. This high flow oil return helps to evacuate power robbing hot oil quicker. CNC machined to exact tolerance from 6061-T651 billet aluminum and then polished to a mirror finish makes these extremely pleasing to the eye. The feed and return gears are individually matched to each body for maximum flow and the ports enter and exit from the bottom of the outer cover for the cleanest look possible. 1973/1980 models required the use of a crankcase oil passage drilling jig for proper installation. Made in the U.S.A.
