Spacer length? (Progressive Springs)

You used spacers even with the adjustable preload caps ? I didnt use any. Set the caps to #1 detent, Screwed them on, Adjusted them to the #2 detent.

I got one leaky fork seal. When I get around to fixing it I might try a couple short spacers. Thats gonna be hell getting those caps started.

The po gave me the bike with no spacers so 2" worked out.
 
Hi guys,

I didn't have time for "the long way" into work today so I took "the medium way". What a difference. My bike doesn't ride like a '67 Caddy any more. It was firm, but not uncomfortable. The corners I took felt great. I had a couple of little wobbles but that may have been due to my lousy riding habits.

I used 1.75" spacers as was recommended in the Progressive documentation for my bike. I had no trouble getting the caps screwed back on. My bike has air forks and not the adjustable pre-load caps. I have not put any air in my forks and I don't think they're going to need any. There is much less dive when I hit the front brakes.

The new shocks have much less sag and subsequently raised the back end a little, shortening the steering. I also left my fork caps exposed (raising the forks by 3mm or so) in case I needed to change the spacer length or put lighter oil back in (currently 15w).

I'm going to ride it a while and see how everything settles in. I have heard that 15w oil can sometimes let your front wheel hop more (slower rebound dampening?) thus lessening your ability to keep the front wheel planted in sharp corners taken aggressively. I'll take a run over Glendora Mountain Road and Glendora Ridge Road as soon as I get a chance to see how the handling has been affected. Up until now, none of my regular riding buddies (except for maybe Lynn) have been able to keep up with me in the corners. I hope I didn't screw anything up. :o

Mr BassCliff... How about those shocks? I've read they can be quite stiff. I put Progressives in my "T" and they seem fine running on the softest preload. I need to decide on my "E" model as the original shocks are getting tired... so what's your opinion of the EMGO's?

Thanks in advance..

Hi Mr. 81ZUKI75,

Well, I've got a total of 35 miles on them now. :p

Yes, they are much stiffer than my old stock shocks, but not uncomfortable. I'm glad the 850G has a wide, dual-density foam seat. It's a heavy bike too, and I'm no lightweight for that matter. These three things lessen the effect of the stiffly sprung Emgo shocks. I definitely feel more of the road surface as I ride. Is that called "feedback"? :D

As it seems so far, I don't think I'll have any trouble going for 2 or 3 hours at a time. Next Saturday my church group has a ride planned over ACH. That will give me a few hours of solid saddle time. On a lighter bike with a lighter rider, these shocks may be a little too harsh. Your mileage may vary.

There are plenty of other members who have used these shocks. Feel free to search the forum and read their opinions. Just search the Tech section or the General section for "emgo shocks" or "mdi shocks" (further narrow your search by searching just the titles). I'm sure you'll find plenty of posts. Maybe even search the Performance Mods section. If you search one section at a time you won't be overwhelmed with non-relevant posts.


Thank you for your indulgence,

Cliff,
That picture of Jessie without her front legs looks familiar. Brian and I (mostly Brian) replaced mine with new progressive fork springs a month or so ago. We did the steering stem bearing at the same time. Hence, the more disassembled look.

I think you're going to like the upgrade. I know I have.:)

Hey Larry,

Yes, that's a familiar scene. I would enjoy spending time in Brian's garage too. He's the real deal. I visited Brian once but didn't get a chance to do any wrenching.

Maybe the next time I change my fork oil I'll go ahead and take a look at the steering bearings. But for now I do like the suspension upgrades. I can't wait to try it out on my favorite twisty road. :)


Thank you for your indulgence,

I fitted a set of the Emgo's/MDI on a 550. Bit heavy for me at 165lb but pretty perfect for my friend at about 240 odd. I suspect Basscliff's 200 + heavier bike is spot on.

Dan :)
 
Hi everyone,

I just thought I give an update.

The new Progressive fork springs have breathed new life into this old girl. I like them a lot but they need a little tweaking. I think the ride is just a little too harsh so I'm going to start shaving off a little from my spacers. Right now the spacers are at 1.76 inches with an extra washer on top. I'll start by removing the extra washer. :p

More importantly, I installed the springs with the tightly wound side pointing up. I'm not quite sure why I did that. Perhaps something about saving a couple of ounces of unsprung weight? Anyway, the springs are noisy. I hear a distinct "clunk" or "thunk" when I hit a significant bump. The documentation said that this could be a problem with the tight winds on top. I'm going to turn them over the first chance I get to see if the noise goes away.

I also used 15w fork oil. I might go back to 10w if the harshness doesn't go away. It's not too harsh, as in uncomfortable, but I feel every little nuance in the road. I guess that's not a bad thing. Thanks for listening.


Thank you for your indulgence,

BassCliff
 
Thanks Dan,

That's good to know. I think if I shorten my preload spacers just a little, and turn the springs over so they don't make noise, then I'll be happy. :)

Which way did you install your springs? Tight coils down?


Thank you for your indulgence,

BassCliff
