DRAG SPECIALTIES Oil Pump (ref. 89655) — a high-flow pump designed for air-cooled and air/oil engines. Engineered to enhance oil flow in the circuit and limit oil accumulation in the crankcase, it is aimed at road preparations and vintage/classic machines that require constant pumping at both low and high RPM.
- Measured performance: +126% flow and +131% recovery volume at 1,000 RPM, and +123% flow and +146% suction volume at 2,500 RPM compared to original 4th generation M8 pumps.
- Optimised design: modified suction ratio for improved discharge on the suction side, reducing oil accumulation in the crankcase.
- Improved oil flow: insertion of a correction spacer between the high-capacity pump and the camshaft support plate for smoother oil passage.
- Integrated sealing: sealing gasket between the pump and the crankcase included to limit losses and leaks.
- Usage: for air-cooled engines only (suitable for air/oil models).
Ideal for owners of Harley-Davidson CVO 121 (Road Glide, Street Glide) and other large air-cooled twins seeking better oil flow without compromising installation. Product sold individually.
