I just fitted the Hagons but it's pouring down, so have not tested yet.
My springs came with 2l of 10wt oil, so if the front end is still too soft I'll try 15wt.
The old oil from my 2002 bike with 5,000 miles on it was very clean, and a nice red colour. I removed about 650ml from each leg and a 130mm air gap (springs removed, leg compressed) used about the same to refill.
I did notice that the level sinks gradually, and its worth pumping the leg a few times to ensure all the air has vented from the fork leg.
My old springs were not progressive.
