I have a 2004 road king 88 inch,S&S 510 gear drive cams,thunderheader 2 into 1 exhaust,Twin tec ignition module ness stage 2 big sucker air cleaner and have recently acquired a screamin' eagle mikuni 42 mm flat slide carb.I have read they are awesome and the throttle response with them is the best.also says on tc engines you may have to file a fin to clear the float bowl on the cylinders.and that you need to reroute the throttle cables.Is this an easy install and what are they talking about with the cables? performance wise am i gonna get a good result-I am planning on a 95 inch kit this winter.Thanks,Ben
