Description
Jims JIMS, ‘Flow Pro 1’ billet oil pump kit. Black
73-91 Big Twin (NU)
With bottom feed & return oil lines. CNC machined from billet 6061-T651 aluminum, with a clean custom appearance. The Jims Flow-Pro 1 oil pump increases oil scavenging (return) when compared with stock pumps. Less oil dragging on the flywheels is more power to the engine. All four oil pump feed and return gears are individually matched to each oil pump body, creating a maximum efficiency pump. Note: 73-81 cases will require one simple drilling step, for which the S&S oil pump drill jig (MCS 518150) can be used. No provisions are made for front or rear chain oiling.
