This shows Step 6 of our 2005 Harley Davidson Duece demo build. This graph is the actual dyno test after the installation of the S&S 510 Gear Drive Cams. Step by step chronological dyno testing brings this otherwise stock Duece up to 80 hp at the wheel. All parts were installed by Cycle Solutions Inc. 765-768-6000 and boxoflube.com. Technician Cody Crouse was our installer and tuning was done by Chris Waddell. Other parts used were NGK Iridium plugs, Jet Scream breather, K&N oil filter, boxoflube synthetic oil treatment and service.
