Oh look! Progressive springs!

[cmonSTART]

I'm replacing my fork seals in my '81 after blowing the right one on the way to Laconia this week, and I discovered I have progressive fork springs. Anyone know the fork oil recommendation with these in place, and PSI while you're at it?

Thanks!

ATF for the oil. Most use no pressure or maybe 5psi with them.

I tried atf first then 20 wt fork oil.
The 20 wt firmed it up a bit. I think I like it more with 20 wt.

I've got Progressive fork springs on deck to install in my 82 and have the springs and seals for the shock seal too. Just waiting for the time to install them. Basically got them so I could retain the air ride but have the Progressives in both ends in case of a leak. Supposedly can ride with no air.

When I put in my progressive springs, I went with 15wt fork oil. The ride felt over damped so I put in 10wt. I recently realized that the TRAC anti-dive was my actual problem. When I moved the TRAC setting from 3 to 1, the over damped feeling went away. Now it is under damped. I plan to go back to 15wt when I have the time. I figure without the fairing, I don't need the 20wt.

How did it feel after returning to 20? I'm about to get progressive springs and they recommend 20. However, I also have no fairing.

I have a 1981 GL1100 and want to get the progressive springs for the forks- I saw some on Amazon for 69 bucks, and on the progressive site they were 90 something dollars. Problem is Amazon says the springs don't fit, Progressive site says they will. What is the correct part number and length of the spring needed??

If you were at the PS site, you have the part number. I'd be confident they know their stuff better than a retailer.
They fit a LOT of bikes with that one part number.

Part #1102 should fit the GL1100, they are the same rate (45/70#) as the set for the GL1000 (part#1100), but are 1/4 inch shorter. There should be piece of paper in the box with specs for the right spacer length (if needed) for your application.
