I've been searching old threads but still have a couple questions. Is it ok to run it on an S&S super E without a backing plate? The only thing holding the carb on is the intake manifold, is the carb gonna stay in place without being fastened to the heads? If not, will a hacked up S&S backing plate work with the 4" filter? I know from the old threads that a SE backing plate works for hacking and fitting, but I have an S&S backing plate, and no $$, the mooneyes a/c was super cheap and looks cool, so I'm trying to make it work. I'm not a welder yet, but I have a cutoff tool and some files.
Also, it's an FXR with an 89" evo, is the 4" filter too restrictive? Will it flow enough air for the STD heads and .561 cam? Thanks for any advice. It's not a "chopper", but it is my daily rider.
