The truth of the matter is they run OK from the factory, can they run better??? You bet!
They run just fine from factory
Smitty,
My FXSTC is as stock as they come, my jetted '03 sportster runs better.
The Softail hunts for what seems to be a better mixture on a light throttle over a level road. I tried the X14IEDs "no change" then the SE race fueler. Spent hours trying different settings "no change" back to no gimmicks now. Same ol'

Sounds to me like there is something else not working as it should.
If the bike does not run right you will likely not be able to mod out of the problem. The bike should run right before you do mods.
Gilder suggest air leaks that a good place to start
BUT.... the surging at a steady throttle indicates what?

Witch can be caused by
Air leaks at intake
leaks in ehaust
Stgae 1 with out adding fuel
Plug gap to wide
dirt fuel system
lose wire at coil or ecm
