In the first half of this how-to oil pump install, we left off with hand-tightening the pump's bolts to the engine case and verifying that the pump's gears spun freely in their housing. Time to finish the job and start enjoying the benefits of having a better oil pump on our 97 Evo.

We all know how important it is to keep cool when you're riding your motorcycle on a hot day. The cooler you and your trusty steed are, the longer you can go, the more time you spend in the saddle, you get the point. For your motor, oil is the lifeblood of heat management. A good aftermarket pump like this one from S&S Cycle is like upgrading the heart that pumps that blood. Hence why we added one to this 1997 H-D Evolution powerplant. The S&S High Volume High Pressure (HVHP) oil pump kit provides 38 percent more oil supply volume, as well as increased oil pressure, and offers 61 percent more scavenging than stock 1992 and later Harley-Davidson oil pumps.
