Both motorcycles competing during the speed trails at Bonneville used Dynacycle Oil, a 20w-50 semi-synthetic motor oil known for lowering engine temperature and increasing horsepower.NRHS V-Twin Performance, owned by Dan Dunn, is located at 1804 Skyway Drive, Unit B, Longmont, Colorado, 80504. His shop specializes in CNC Headwork, Bore Kits, and “All things Harley and Buell.”In addition, Dan and the NRHS Team have set the record for the “Fastest American V-Twin” at Bubs at Bonneville 6 of the last 8 years.Dan Dunn says: “(he and his race team were) very impressed with how well Dynacycle Oil stood up. After running over 12 passes at RPMs above 7,500 for 2 miles at a time, the bearings and pistons still looked like new. Anytime you can see a gain in horsepower with less heat, especially under the grueling conditions of the Bonneville Salt Flats, we consider that a win-win. Dynacycle Oil did just that for us.”The Dynacycle Oil Company is a biker owned and operated business established in 2003.
