Gl1100 rear shocks
Hello all!
This topic has been on here 1000 times but I can't find the answer I need..
Found some of the answers but not All...
Ok..
Need to rebuild my rear air shocks... bottoms out with me And the old lady on it..
Yes we are fat.
Doesn't matter..
So my question, can I use a heavy weight for oil instead of ATF to fill the shocks to achieve a stiffer ride with less bottoming out, say a 30 weight..I Know I can use fork oil..but I guess what I'm trying to decide is if new seals and a heavier fluid will do the trick without having to buy new/progressive springs...I'd rather not have to build a tool and deal with that..hate to go to all the trouble to rebuild them and still have an issue..
Trying to keep it simple and affordable.
Anyway, that's my question.
Thanks for the help people!!

As far as heavier weight oil, I've not tried it, so I can't say for sure...

Re: Gl1100 rear shocks
heavier weight will slow them down lots of info on front forks oil wt. think it's the same for shocks except if yoiu don't like the feel it's A LOT harder to change

Re: Gl1100 rear shocks
this thread is relevant to my issue. my rear shocks on my 82 are leaking air. no fluid. I haven't checked the lines yet but if there is no leak in the lines, does this mean a shock rebuild?

Re: Gl1100 rear shocks
The 76 shocks are eye and clevis, the 1100's are eye and eye... replacing the seals on the 1100 shocks is relatively easy. You don't need the jig unless you are replacing the springs (or the internal bump stop that is ALWAYS decomposed due to the fact that it isn't impervious to the shock oil). One of these days I'll get around to posting a how-to on a full 1100 shock rebuild...5speed wrote:eyes the rear shocks on his yet to be finished 76....RB wrote:yep..

Re: Gl1100 rear shocks
tks for the info. I have my fingers crossed it is a leak in an air line.
I put 35 psi in them and checked them 3 days later and there was no air pressure at all. But no sign of a fluid leak on either shock.

Re: Gl1100 rear shocks
Sounds like a leak in a line. If a seal were bad, it would almost definitely leak fluid. There are several o-rings in the system as well. I replaced all of them when I did my shocks, no more air leaks...

Re: Gl1100 rear shocks
Well..I put 50 psi in the shocks and sprayed soapy water on all the fittings..nothing.
No bubbles, no hissing..
I'm starting to think this bike is possessed.

Re: Gl1100 rear shocks
Hey Tedfeast.
Been down this road and know exactly where you're coming from.
Got my '82 a few years ago: Windjammer on the front and Bates top box and side panniers at the rear.
Rear bottomed out first time I sat on the bike. I'm 220-230 lb.
Pumped rear shocks to 57psi. Felt better .... until on the road.
Didn't take much to bottom out quite hard. Hmmmm.
Fitted the Progressive upgrade springs as well as renewing seals.
Only marginal improvement.
Very dismayed at only 3 1/2" travel.
Also ... I scraped pegs, stands thru corners as rear was so low. Grrr.
OK. Need longer rear shocks for more cornering clearance.
Found some Progressive 14.5" Air Adjustables.
Got more cornering clearance, but also a hard ride solo; much better with passenger.
Running 0 psi pressure.
Turns out these were for the 1500: about 150lbs heavier than my Standard 1100.
Tedfeast - from what you've said, I think a set of these might be the most effective and simplest way to go.
As bought '82 Standard.
More nekkid, with 14.5" rear shocks. And does it corner ... muahhh harr harrr ...
Cheers.

Re: Gl1100 rear shocks
I have seals to rebuild my 1100 shocks and new Progressive springs. With the seals gone on one side the bike would develop a weave at higher speeds. Procrastinating the task I put on 1500 shocks I had. One is a traditional coil-over shock, the other is a large canister with just air. It rides surprisingly well. Seems to be easier on my back.
However at around 80+ mph it develops a weave still randomly. Not always. I wondering if the car tire is some of it, (but it did it with the 160 Avon on it too) and that hitting some long grooves starts it.
I question having unmatched shocks in the back. You’d think the swingarm would cancel them out, but I wonder if the swingarm is flexing some. I guess I have to make a jig.

Whatever I suggest here should be given ample time for a moderator to delicately correct. I apologize in advance.
