Well, there's my last of my 3 scooters....It started as a 2019 FXDRs 114....but....
It's now a 123 using S&S parts,65mm throttle body, K&N air intake system , large fuel injectors, HD electronic tuner (before EPA sued them because of emissions) Bassani Exhaust(tuned for my system with no cat converter) and a lot of other stuff. I've never ran it as fast as it can go.....I admit I too old for speeds past 125! As a side note...My Model A has a motor out of a totaled '68 Shelby GT 350 coupled to a B&M C6 ford tranny in it!
