Hey Vic,

Did you pop the front forks off, or are they still mounted on the bike?

If on the bike, is it jacked up so there's no pressure on the front wheel and the forks are fully extended?

When you say the ends won't screw into the mounts, is it because the longer/ stiffer spring is really not wanting to smoosh down?

If you popped the forks off the bike, did you remove the damper piston? Is there any wiggle room in how the damper piston is mounted to adjust for the longer springs?

Might want to consider "progressive springs" for the forks. Those tend to give a pretty plush ride but better control under heavy loads. Most of those are "universal" in that the only difference between bikes is spring diameter and length. Appropriate spacers used to be included, but last time around on my Royal Star, I had to make my own - used schedule 40 PVC pipe per the factory for that. I doubt there's any made specifically for the Ural, so you'd have to play around with spacer length to get the preload right, but just aim for a spring set calibrated for the same approximate rolling weight and you should be close.

OK - that takes care of compression - now all you got to do is improve rebound. A thicker oil is usually the trick there. Go up 10w and see what happens.

And yes - changing suspension can get ... interesting. Be prepared to do it a couple times to get it right if you're picky like me.

I have a 2001 Deco. Servicing the forks makes a big difference. I went from the front end diving all the way down on a medium stop to a modest amount of downward travel on medium stops. Panic stops I still get a little more downward travel than I would like but I think that is a limitation for the forks. I used Harley Davidson Type B fork oil.

I remember servicing all shocks on my former 1999 Deco. Changed the seals and oil. Gene Holopaw had all rubber parts - seals back then. You may want to check with him.

Big Vic, I’m in the same boat so to speak. I’m a big guy and I recently purchased a 2004 Troyka which also has telescopic forks. I’m curious how things worked out with the Progressive springs. Also wonder if you went with a heavier weight fork oil.

I was going to suggest giving Dave Quinn a call as he is (or was) the leading distributor for Hagon Shocks in the USA. In looking up his contact information I came across an Adv. Rider thread stating that due to health issues Dave is not longer associated with Hagon.
That's too bad because he was a wealth of information regarding suspensions (yes, even for Urals) for many years. Helped me out with some BMW issues whether I was buying from him or not. Personal touch.

Try this site as I see they do deal with GAZ & Wilbers (they say better than Ohlins) as well but sadly no actual name:
