An oil pump drive gear set to double the oil pump speed of the Big Twin
engine. The benefits are two-fold; increased volume for improved cooling and
lubrication in big engines, and improved oil scavenging to move oil out of the
engine quickly for less internal drag and higher horsepower output. Oil pressure
can be controlled by simply installing an optional oil pressure bleed-off system
(instructions included).
