How too stop bottoming out when turning or riding !!!

Postby kajunmisfitt » Mon Mar 31, 2014 10:25 am



HELLO IT IS ME AGAIN,
I hope everyone is doing great, Got something I need cleared up for me. I was riding the other day with my oldest son (150lbs) and I noticed that when we made some turns the exhaust would scrape the road and when we hit some bumps in the road, the bike would bottom out. But when I am the only one on the bike it doesn't seem to do these thing. I put air in the rear shocks around 55-60 psi. But I went looking in the HOW TO DO IT section on here, What I did find was someone talking about replacing the rear springs. I can't find any articles talking about this. I am not really wanting to go tear the rear half of my GL1100A, all up too do this project if I don't have too. So can someone tell me what I might do looking at doing to stop this from happening Or am I going about this the wrong way. Seem like I am tearing this bike down for every little deal. Again "THANKS" for the help ahead of time !!!!

I changed my rear shocks for a pair from a 1200 and when me and wifey go out I use about 65psi in rear. Bike only grounds on sweeping bends when I am pushing it a bit.
The only silly question is the one you don`t ask. Everything else is game.

Your springs are 30 years old, they are going to have lost a lot of their "springiness" over those 30 years. I know mine were sagging a little bit - when I replaced them (as shown in the article I wrote, How to remove and replace your rear shocks) with the Progressive shocks, the bike sat a good inch higher, and it made a huge difference in how it handled and turned, especially with a passenger on board.

thanks guys, I have this other GL1100A and it has some crud on these struts so I am not sure if it just needs to be replaced. So I might look for the spring too see what happens

Congrats, you are the proud owner of a 30+ year old motorcyle. You are going to have to replace/fix and adjust many parts as you get to know your "new" bike. So until you have gone through every system, every sub-system and every servicable part you will continue to be fixing items.

We ,your new friends here at GoldwingDocs will be happy to help any way we can.

Now in regards to your suspension issues, I had the exact same problem with my 82Aspy the first year I owned it. Everything seemed OK until I had a passenger or pushed it a bit faster through sweepers. The bike seemed to wallow in the sweepers and the rear would bottom out if there was a good dip in the road. I would be willing to bet that when you put the bike on the side stand it still sits pretty upright, wouldnt take much of a push to have it fall over to the right would it?

The solution? New springs front and rear. Specifically Progressive Suspension springs. You can buy them on Amazon.com , at least that is where I got mine a few years ago. These are just the springs inside the forls and rear shocks. You will need basic mechanical skills and tools to install them yourself. You will also need to buy new seals( they are inexpensive and even if the old ones dont leak now they will soon enough) now it the time to change them. Put in new fork oil and you will be amazed at how well your bike handles. Plus the bike will sit a little higher, back where it is supposed to be. Your side stand will allow the bike to lean to the left a little more so you wont have to worry about a stiff breeze knoking your bike over when parked.
I am working from memory here but I think my total cost for front and rear parts was less than $250, but that was a few years ago. I will see if I can find you a source for the parts you need and post back here in a bit. 8-)

Here we go,

Front springs on Amazon for $68
http://www.amazon.com/s/ref=nb_sb_noss? ... on+11-1102

Rear springs to rebuild your stock shocks $50
http://www.amazon.com/Progressive-Suspe ... automotive

Non air shocks for the rear 412 series $277 simple unbolt the old, bolt on the new.....
http://www.amazon.com/TOR-SPRNG-GL80-83 ... +412-4222c


The seals can still be sourced from the Honda dealer as well as the slider bushings for the front forks. The whole project can be done in a day with frosty beverage breaks along the way. 8-)

Yes replacing the springs will increase ride quality and height. one question; which exhaust are you running? The one on the 83 I own seems to sit higher than the one on the 82. (my 82 exhaust is aftermarket)

Usually I scrape the pegs before my exhaust hits which is why I ask.

WOW,
Y'all are AWESOME !!!! THANKS FOR THE INFORMATION. If I am understanding y'all ,if I do the front seals then that should take care of the front. And I am not using the 83" exhaust that one that are on the 82' is stock I think. I haven't changed anything but the fuel filter, spark plugs, and added a few lights. So I am looking too get this done without the min amount of difficulty. I am learning a lot but I got this feeling that this bike has a date in the future with the dealer or a certified mechanic. the air gauge has not changed since I put air in it last week. So I now that there isn't any leakage from the struts. I am assuming that I am going too have too take the saddle bags off and the seat too get to the air shocks. But I am wondering if I could take the shock off the 83' and rebuild them and put them on the 82' WAIT ! WAIT !! That make since, But I have a feeling y'all are going to tell me I won't be able to do that. But I hope y'all tell me I can. Talk to you soon thanks for the education guys !!! I do appreciated it !!!

sure you can! the 82 and 83 are almost exactly the same. the real question is why would you when brand new air suspensions (from progressive) are cheap and better than the originals.

On your rear shocks what do you have the ride setting on? at the bottom of each shock are what look like stairs I have mine set to tallest step and the stiffest ride.

By the way I weigh 250# and carry someone that weighs 240# and tow a trailer.

The airshocks do not have any adjustment for preload other than more air. These are not the same as your shocks . I suspect that the PO has already changed out your shocks . Rebuilding the stock air shock is still cheaper than buying new 412's and yes the 83 has the same shocks as the 82. 8-)

This is good too know, I went and looked at the shocks on both bikes, my bike (82') has a bunch of dirt, but it appears that it is only dirt and dust from the road. NO OIL/GREASE !!! and it doesn't look like the rubber boots are in good condition too, Guess that is a good thing. But the (83) parts bike it is got oil/grease and dirt all over it. and the rubber boot that goes from the middle of the shock too the bottom is split and tore. And the only thing written on the outside of these shock are "air suspension". Not sure if this will help y'all tell what /who made these shocks !!!!

Ok, Not to beat a dead horse, But what I understand is I buy these Progressive Springs and just mount them under the Rubber boots. I have no ideal where they go. Or do I have too but another air shock too go under/with the new springs? I am sorry I am not seeming too be able to get what yall are trying to tell me. Since I have checked the ones on my bike (not the parts bike,(the pars bike they are out in the open since the saddle bags are not on the bike anymore. Since I have never done this before. I wonder if I just take the rubber boot off and slide the spring on . Something's I have not done before so I am not in a hurry too go tearing things without finding out what the next step is. So again guy I thank you for the patience you are giving me. Son I hope this is a less complicated project. thanks

You must remove your stock shocks, take them apart, remove old springs, install new progressive springs, seals, etc. and reinstall. The springs are inside the chrome body. You "rebuild" with new springs.

I helped a buddy rebuild the rear shocks on a 82 wing. I dunno , with all the hassle of ordering parts , head scratching and labor - when it came time to do my 1980 wing rear shocks- I said the heck with it ,and purchased Progressive 412 adjustable non air shocks. Around $295 was the cheapest I found on e-bay.
Better than OEM. Well worth the money spent. Makes a BIG difference in cornering and overall handling. And quite a bit easier also ;) . Regards, Johnny

I replaced mine with the air-adjustable Progressive 416's (on both my 1100 and my 1500) and love them. They're quite a bit more expensive, however.

Hey, I have to say,, I felt like a quick fix, I pulled the trigger on the 412's, the bike is higher and doesn't bottom out and I'm large at 260 lbs it went up an inch, took a few minutes to install and I don't have to screw with that air anymore... Never looked back, got the springs too for the front...Progressives....It's a lot easier putting it on the centerstand too.... :D Truth is... I didn't feel like getting wacked in the head trying to build it...or I was just lazy...yep that was it.. :lol:

I'm having problems finding the "correct" shocks for my 81 GL11001 Interstate. When I look for the shocks, I'm getting a message that these shocks (the 412s and 416s) won't fit my model. Even Amazon has this message pop up. Could it be that they don't know?

They definitely fit - checking Progressive's own site for a 1981 GL1100:

http://www.progressivesuspension.com/pr ... -gold-wing

Keep in mind that there are many different models of 412 and 416 shock, for different bikes. The ones you want for your bike are:

416-1622A

412-4222C

I see the 416's for your bike on Amazon here: http://www.amazon.com/s/ref=nb_sb_noss? ... ingdocs-20

However I don't see the 412's being sold on Amazon at all.

A lot cheaper than buying new.

Excellent videos! I assume you did buy new springs and replaced all of the rubber bushings and Orings as part of this rebuild. Did you have much trouble getting all of those pieces from Honda?

I got the springs from progressive and the rest from partzilla. I try not to visit Mother Honda for anything.

I still have the piece that was rounded out to fit. The top piece. It is available to anyone who wants to use it. You pay shipping to you and shipping return to me.

I want to thank everyone who has contributed to this discussion. Being a new Goldwing owner (1981 Interstate), I know I don't know much about them, but, with all of you and your help, I'm gonna learn a bunch. I didn't know there was a difference in the 412s and which bikes they would/wouldn't fit...and the instructions on re-building the originals was fantastic. You can be certain that I will hang around and poke my head and pick up more info from you guys. Again, many thanks!
