I have an 07 E-Glide std that I ride solo and would like to change my front forks to ride softer. Can anyone tell me what weight the Harley fork oil or the Screaming Eagle fork oil is?
Seems my dealer doesn't know since they haven't answered my question.
Or does anyone have any experience in this?

I talked with a guy at Red Line about this when I changed over, here's the info he sent me. "Harley Type E has a viscosity of 39 Centistokes (cST). Red Line Medium fork oil is 30 cST and the RedLine Heavy is 67 cST. They can be mixed to make any viscosity in between."
If my math is right, straight RedLine Medium would be 23% lighter than stock and a 75/25 med/heavy mix would be the same as HD. I'd say you're shooting for something in between.
For what it's worth, I wanted a stiffer action and have been running a blend about 55% heavy (about 30% stiffer than stock). It's the best this suspension has ever felt and will be my new standard.

I have an '07 FLHTC and switched over to SE Heavy fork oil at the last oil change. The front suspension response was much improved. It's stiffer but not harsh. The front end seems better connected with the road. I'm not an aggressive rider but I wouldn't want the suspension softer than stock - don't want to hear that sickening clanking sound of the shocks bottoming like I did a couple of times before swapping to SE heavy.
One other thing you might look into is swapping the springs for a set of Progressives, maybe back the preload off 1/8 - 1/4" from spec if you're dead-set on a softer ride. The Progressives handle small hits better.

I wouldn't try to go to a lighter oil to get softer. If you do, you are gonna be more likely to ding your front fender on the brake tee bolt under the triple tree....I did it with stock oil and some air in the front forks...(I know your bike doesn't have air, so it will be even softer than mine). If you hit the brakes and a hole, railroad tracks or whatever at just the right time, the fender can contact that bolt leaving you a nice little ding.

I switched to the SE "Heavy" to deal with the front end dive and it did.
A couple of days ago I installed the Progressive Drop-in lowering kit and dropped the front end 1", and added the SE "Heavy" fork oil. This setup is a big improvement over stock. No front end dive on braking, and a noticeably smother ride.

i put in the se heavy, when doing the chrome fork changeover. a huge improvement in road feel and the ride did not suffer, or become harsh. no longer does it handle like a 77 buick, the nose dive when braking is all but gone, and if you get any softer in the front it'd handle like a pogo stick if that well.
