Can any body explain exactly what this download does?
also can i put a high flow air cleaner on without the need for this download? I'm
still running stock pipes
HD Stage1 download will richen up slightly under throttle, but still leaves you very lean at idle & cruise = heat issue not really resolved, but does give a little better throttle response.
Just an a/c will let in more air and make you leaner, that is why Stage1 is usually a/c, slip-ons, and download.
You can leave all alone and do just slip-ons as this will not make lean condition less.
I would at least do a V&H FuelPak or something similaras the download still leaves you keeping the EPA happy. This opinion is based on the 0796" engine.
not knowing any better i went w/ the stage 1 . bike ran hot, deceloration pop was horrible. i then went to the pc111. bike is not as hot as it was and no deceloration pop. if i knew then what i know now i would skip the stage 1 and go straight to the pc111 or some other fuel mgt. system.
I did the stage 1 no problems what so ever but hd recommends staying with s/e slip-ons and air cleaner.works best over 3k rpms you can fell the difference
