The front end of my 2010 Road King dives down pretty bad every time I come to a stop - even when I'm barely touching the brake lever. Seems to me the old technology with the air assisted forks was better. It would isolate the air in the fork tubes with a little electric valve whenever the lever was used. When you weren't using the brake the valve was open and the air in the forks was connected to either the crashbars or the handlebars, depending on the year of the bike.

I read somewhere that Eric Buell developed the system when he was an engineer for Harley before he started making his own bikes. That system really worked and it gave you more control coming to a stop because the bike wasn't so sensitive to weight transfer from the front brakes.

 

Replace your springs with Progressive Suspension standard height springs.

 

after the evo system, I'm happy with the 09 FLHTC.

maybe a heavier grade oil would be an easy swap for you

I had the dealer install chrome front end on my bike. I had them put heavier oil in them. made a huge difference in front end dive.

 

That sounds like it would be a neat system. I have 1996 Road King that has air assisted front forks but it dosen't have any electric valve that you mentioned, just has an air line to forks with fill valve inside rear of headlight housing. Comes in real handy when changing fork oil using a hand held vac pump. I always experienced nose dive no matter what air pressure I used. The higher the pressure in the forks the harder the ride but it didn't help with dive. I read that switching to heavier weight fork oil would help. I used Harley Screamin Eagle heavy oil and I have no more front end dive, ride is a little harder than before with air pressure so I do not use air now at it works just fine. I would suggest trying heavier oil and see how you like it. It has to be better than dealing with that diving front end.
