Installed the Arlen Ness big sucker intake today, it was really straight forward, great kit, and great price. A forum member suggested while I was at it to do the air hose marble and remove the secondary throttle plates. (thanks John I really appreciate the help, sorry I can't remember your name on here) the little Philips head screws that hold the throttle plates on are a bitch! John recommended to use an impact screw driver as the aluminum screws will strip out super easy. I took his advice but I borrowed my neighbors electric impact, no good! Stripped the screws and ended up having to drill em out. All said and done, the bike is indescribably better. No more pop, no throttle hesitation and quite a bit better acceleration, also downshifts are much more civil without the throttle hesitation. I have Vance & Hines slashcuts and a pcV, once I get a different tune on it should be real nice.
