IMO, this is HD's last feeble attempts at providing a motorcyle with an engine basically designed in what 1911, to meet the new strict emissions of today.
Air cooled engine will never run with power with AFR of 14,7/1 or leaner, but they attempted it anyways. Adding extra tall gearing, cams that raise compression early to "fake some power", then fall flat, cats, are all attempts to get these dinosaurs past emissions testing.
They can be made to work, new cams, no cat, lower gearing, decent exhausts and retuning to meet the actual "needs" of an air cooled motor wake these up. Unfortunately, I believe the costs of trying to meet emissions has twisted HD's arm to look for alternative ways to save $$, the results show in twisted cranks, compensators that are junk, overseas parts that fail (regulators, lifters etc etc).
It can all be corrected, BY YOU, or you could buy a Victory, and be happy.
