I ordered them last week and I've been trying to read up on how to do the install.  I'm putting them on a 98 GS by the way.  I'm planning on doing the lazy install and I'm wondering if I should change the fork oil while I'm at it (the lazy way...with the syringe).  I weigh 200 lbs...should I replace the fork oil with 15w or should I just leave the 10w in there and see if I like the handling with the 10w?

Also, I'm running my stock rear shock at the second to last highest preload setting (6...I think).  Should that be about right for my 200 lbs and the new progressive springs? 

THANKS!

If your fork oil has never been changed, it's probably a good idea to put some fresh stuff in there. I weigh 180 and I put a 15w oil in when I swapped my springs.  As for the rear shock, I had mine as high as it would go. Until I switched to the kat 600 rear shock.

The lazy way really doesn't save you much time at all (the only real difference is that you are spared removal of the front tire) But if you're set on doing it that way, I would suggest changing the fork oil. Fork oil should be changed every couple of years as routine maintenance.

I weigh more than you and used 10W with the Progressives.

Do the progressives make a very noticeable improvement even with the 10w oil?

YES! 

I agree also.I'm 200lbs and used 15w oil.Works great if you're over 180lbs.I don't recommend using Suzuki brand fork oil.I total rebuilt my GS forks and added progressives and 15w Suzuki fork oil.Checked the oil at 1000 miles to be sure they were holdin up,and the oil turned from a golden color to a gray color.
