Hi there, new to this site and from what I've seen it's the best HD site so far. OK enough sucking up

. I just bought an 88 FLHTP (my first Evo) and I was told that it was geared differently from civilian models. Can anyone tell me what the ratio was? Is the tranny geared differently or was it done with the primary or final drive sprockets? Is 5th still 1:1? What would I be looking at for RPM's at say 30, 60 and 80 mph?
