Rogue did it again. A stellar tech about some hot new products from Zippers, JIMS, and Feuling. "I started off intent on just check the cam chain tensioners on my 2009 FLHTC, and then thought, what the hell," Rogue said. "As long as it’s apart, I might as well upgrade to the Zipper’s Red Shift 525-HS cams. The 525-HS cams are a set of bolt-in units, and they allow me to use my stock pushrods, plus no changes to valves or springs were required."
