Suspension Headaches For 15 FXDF
Did you go with 15w amsoil or screamin eagle fork oil?

Suspension Headaches For 15 FXDF
I used 15wt Bel-ray oil. Didn't touch anything with the fork spacers either. Basically removed all the stock oil, springs, and spacers and replaced. Sag was slightly stiff but I left it alone. It settled in nice after some road time.
Still running on the stock rears. I go back and forth between 4 and 5 on the preload. 4 is slightly to soft, 5 is better but kinda harsh.
Some nice upgraded rears are for sure in the future, but I'm leaving the front alone.
Good Luck!

I'm the same weight as you and riding a 2013 FXDF that is still stock suspension. Based on all the reading and input I can find from the great riders on HD forums I'm about to do this. First, install Ricor Intimidators in the front and then change to 10wt fork oil. If not fully satisfied I will then try 15wt oil. Like others have said I can't justify the investment of $700-800 for a front cartridge system that might not improve things very much.
If I do the rear (still not sure) I will go with Works street tracker shocks. I don't see the need or advantage to dual reservoir shocks (piggyback) on a lighter weight solo street bike riding single up.

i put the ricor intiminators and amsoil 10w on my 06 it it was amazing the difference it made and pretty cheap mod really.
People have gotten super technical with the fluid level and cutting spacers and preload add ons with this mod but to tell you the truth i just put the ricors in there and changed the fluid. I didn't cut any spacers or anything and it worked out bad ***.
it is on the list for my new bike

can the progressive drop in spring kit still use iniminators?
if so, I think the setup I'll try is
Progressive Fork Spring Kit - Heavy Duty Rate with 15w oil, not sure on oil brand yet
and
Progressive 444's in standard duty for the rear, I just dont think I need heavy duty rate for the rear, unless anyone has any input on that.
that way, the rear end should be good to go, they're adjustable and will probably perform WAY better then the stock rear shocks. if the front leaves something to be desired; then I can add intiminators afterwards.

I don't know 100% because I've never tried, but I don't see why not. They are pretty much the same designed components stock vs progressive.

In my opinion, I think you should stay with standard rate springs up front. If you're sticking with standard rate rear shocks the heavy-duty front springs don't really make sense.
Personally, I would keep your fork stock but switch to the heavier 15wt oil. Go with the standard rate 444's out back and reassess. Your rear suspension is going to make the most difference. After that if you're looking for more I would drop the intiminators in your front fork and go to the recommended 10wt oil with stock springs. I at that point you still aren't satisfied, I would swap the stock fork springs for a straight rate spring from Traxxion Dynamics or Race Tech. After that your looking at cartridge kits.
