I put some of the heavy Harley brand fork oil in my 11 Road King. I put in the same amount that I got out so I know didn't over fill it. Man it was harsh, I ended up draining about half of that out and adding some of the lighter weight oil to soften it up and it was much better.
If I remember right there are 3 different weights of oil Harley sells but they don't say what weight they are. I'm thinking they are 5, 10 & 15 wt.
I think I would stay away from the heaviest oil.

This is what I run in my '04 Road King, and it's what a local dealer recommended. The forks feel a lot better than they did with the original fork oil.

I agree. I only changed to a heavier oil to help with dampening, not to reduce brake dive. It was just something I noticed with the heavier oil.

Depends on your load...how heavy is the load on the bike , if you weigh 300 lbs 2 up soaking wet then the heavy oil might be too harsh for you..compared to 450 lbs like us...I like about 10wt, last time I mixed bel ray 7 and SE racing fork oils, it was perfect.

Thats a good point. I'm 165# wife is 110# thats probably why the heavy weight oil was harsh for us.

I get noticeable braking dive, was going to order springs but my dealer said try SE oil first because it will produce a noticeable difference. I haven't done it yet, but I was impressed that they were trying to save me some $.
