What pre-load are you running on your Progessive 940 Ultra Touring?

I just installed a set of Progressive 940 Series Ultra Touring shocks on my 2009 RG..........

I'm loving the 1" drop for sure...........

I'm still fiddling around with the pre-load on the shocks. I'm a little surprised how little pre-load I'm running given I'm 275 pounds.......

I settled on 2 "grooves" showing, the second groove just peeking out above the top of the adjustment collar. I spoke to Progressive tech support on Friday before the install to ask about the best way to set up the pre-load. His suggestion was to take a hight measurement with the bike upright with no rider and subtract that measurement from the hight with me sitting on the bike. Then adjust the pre-load until the difference was 3/4".

Given my weight, I just would have expected I would need more pre-load.

Went for a short test run today and it actually felt a little stiff.....

What's everyone running?

J.D.

I'm 275 also, and the wife isn't petite. Based on my experience with 440's on my last bike, I started with 6 turns preload, too much, dropped down to 3 turns, and the next time I have the bags off I'm gonna drop it some more. It's OK now, but I'd like to try a bit less.
The 940's are know for having heavy springs, some have sent them back for lighter springs.

I'm 190 lbs, I use no preload for me, and 2 turns with me and the wife (150lbs). Works great. I like a firmer ride, but not a hard ride. I don't bottom out, and i glides over the bumps and railroad tracks with ease.

Im 210 lbs and with the stock springs I did not run any additional preload. I sent the shocks into Progressive and had the softer springs installed with the softer springs solo I run about 2.5 turns of preload and the ride is great

OK guys, everyone keeps speaking in terms of "turns"...............

From the directions that came with my 940's, measurement is in terms of the number of "grooves"..............

"Spring pre-load adjustments are made by turning the Upper (Long)
Cover. Turn this adjuster clockwise to increase spring pre-load and
counterclockwise to decrease spring pre-load. Above the adjuster, there
are 4 grooves, these are pre-load reference marks:

Minimum pre-load = No visible grooves
Maximum pre-load= 4 visible grooves."

When everyone is talking about "turns", are you talking about one complete 360 degree rotation of the adjuster? If so, starting from what position? No visible groovers?

Thanks.

J.D.

I am on the minimum amount of turns. When I have the wife on it I put it on the second turn or mark. Works perfect for me.

I always considered the grooves to be kind ambiguous, hard to tell sometimes if the groove was 1/2 or fully exposed, and no real reference between grooves, so i just turn mine all the way to the top till the collar stops, make a mark on the side of the collar, and then do all my adjusting by counting turns of the collar and ignore the grooves.

Same for me. Adjust the preload all the way counter clockwise ( up to top) made a small mark on the outside of the spring cup. Im running at 2 or 2.5 turns clockwise (tighten)

I'm a little heavier than you, and sit further back than stock...probably moving center of gravity rearward...and run 8 turns solo (just under 3 grooves), 10 turns ( 3 grooves) solo w/ tourpak. It seemed to me it rides firm no matter how low you go, but raising the preload handles/absorbs harsh dips, bridge abutments, etc. much better, at least for me.
