REPAIRING LOWER FARINGS TABS ON 83 GL1100

Postby edr421 » Fri Mar 14, 2014 3:28 pm



I hope that this is the right place to put this information. I know that this is a problem on a lot of older goldwings.

I got the idea from someone who had written about doing this method to reinforce his trunk lid to add a luggage rack.

Both my lowers had the lower tab broken off. I tried to find a replacement and all I found are ones that had been fiberglassed and broke off when touched.


What you will need. 1 1/2 to 2 inch ABS Pipe or fitting, ( black and it is hard to locate, had to order a piece online) IT HAS TO BE ABS, NOT PCV!!!! ABS cement, Heat gun, plier, clamp, hammer, rasp, Dremel tool, sandpaper and paint.

Cut a piece of the ABS pipe to 1 1/2 to 2 inches wide and then split it lengthwise. Take your heat gun and heat the pipe and use your pliers and hammer to flatten it and thin it out a little. Now bend the piece to a 90 degree angle.


Sand the inside of the faring and the new piece. Add ABS cement to both pieces and put the part in place and clamp it in place.
While it is drying take the rest of the pipe and use the rasp to file shavings off onto a paper plate. Then put a small amount of cement on the plate and mix the filings into it to form a slurry. Remove the clamp and fill in any spaces on the outside of the faring and new piece. Clamp it an then let it sit over nite to dry. Your part will look like this.


Use the rasp or Dremel tool to smooth the parts and form tab.


Drill your hole, Sand and paint. Should last forever. Any questions you can contact me at edr4211@yahoo.com

ABS pipe can be found at RV dealers as well as ABS glue, the RV industry still uses it for drain-water plumbing.

I plan on using this method,this week,when I start repairing my '84 Interstate,for painting.
The PO,had used fiberglass,to mend the areas,so I'm currently pulling it all off. Fortunately,it doesn't stick too well to ABS.
I plan on ordering some ABS sheet,and doing some reinforcing on the side bags,and trunk bottoms,as well. They're notoriously weak,so I want to do them before they get messed up.
I also plan on pulling the rails off my saddlebag lids,and filling the holes there,as well as the holes from switches that were removed.
Finding that post was a Godsend to 'Wing owners. Especially with parts getting scarce/expensive !
One other use for it is making custom parts.I have a couple of ideas there,also.
I'm busier than a one-legged cat,in a sandbox !
I can't fix it,if it ain't broke...you want me to break it,first ???

Give me a Goldwing,...or give me Viagra,cuz either way, I'm gonna ride !

Glad to hear it helped, the guy i heard it from used his wifes oven to heat the abs, but you better make sure she is gone cause it will stink the house up. Let me know how it works out

The ABS pipe/slurry/cement method of fairing repair is well known to us Wing owners - you'll find several articles on it here. You took some good pictures. I used this exact method to fix a bunch of broken tabs on my wife's PC800 bodywork last winter when I had it all apart.

Elegant and useful solution.
The latest issue of Motorcycle Consumer News has a back-page article (Innovation of the Month) on Plast Aid. It is used to repair a broken tab and has good photos.

I ordered a small order of the plast aid and used it to make a knob on my shower diverted and it worked great. I am going to test it on another part to my bike. Takes some trial and error but its an interesting product

I need to repair the screw holes and stand-offs inside the trunk lid of my 2003 1800. Is my bike ABS as well?

Yes. All Goldwing fairings, trunks etc. are all ABS.

What about the side panels to the right and left of the passenger? Where the hing tabs break off, are these also ABS and will this method work to repair those?

]Yes it will. Try using the slurry. Also I try the product called plast-aid that was mentioned above. I have used it on several applications around the house and on the fairings to smooth the repair with the abs, the guy who painted my bike loved working with it

I am preparing to repair the lip of my saddle bag on my '83 Aspy. You guys are talking about ABS, that's a term I'm not familiar with. Is that the same material as Kydex(like door panels on cars?) I was going to use fiberglass to repair it but now I don't know if that will work. :?

Abs is the black pipe used a lot in the rv industry. It is similar to pcv pipe of the plumbing industry. But you cannot use pcv pipe. Try older hardware stores, rv stores or internet. Be sure to get the cement for abs. Good luck my tabs are still good.

ABS is Acrylonitrile butadiene styrene (say that five times fast). It's a very common plastic, and just happens to be the plastic used for all fairing and body parts on all years of Goldwings. It is used for a huge number of things, and one of those is black sewer pipe.

One of the great things about ABS is that it can be bonded using ABS glue, which is primarily MEK - methyl ethyl ketone. When this glue is applied to ABS, the ABS chemically melts. If you apply the glue to two pieces of ABS, they both melt, and if you then press them together, they will bond together - not just sticking, as they would if you used a common adhesive, but their melted surfaces combine and become one piece of plastic - which is an incredibly strong bond.

This is why it's recommended to use ABS and ABS glue to repair Goldwing body parts, not fiberglass. Fiberglass is strong and stiff, but does not adhere to ABS all that well - and because it is much stiffer than relatively flexible ABS, and expands at a different rate than ABS when heat is applied, it will eventually break free of the ABS, and the repair will fail.

My normal method of repairing ABS is to use small pieces of ABS plastic to form the tabs or whatever it is I want to repair, and clamp them into place. Any gaps I will fill using ABS "slurry". Slurry is made up of ABS shavings (I use a drill press to drill holes in ABS panels, and capture the drilled-out ABS) and ABS glue or MEK. The glue/MEK melts the ABS shavings into a goo - the more glue, the thinner it is. I apply this slurry to the gaps and use a form if required. Once the MEK evaporates and the slurry cures, it turns into a solid lump of ABS, which is chemically bonded (i.e. becomes a part of) the ABS piece that it was applied to. The end result is that the repair is as strong as (or even stronger) than the original piece.

FYI you can use fiberglass to reinforce plastic. Just use ABS glue (thinned a little bit) instead of epoxy. Works like a champ. You can use this for just about anything as long as you use the correct cement.

Hi,
I was reading the article on Re: REPAIRING LOWER FARINGS TABS ON 83 GL1100. You said that sometimes you make a form or mold, how do you do that. Do you think I can repair the cover for my radio knobs the lower tab broke that bridges for the clip to hold it on? I lifted my trunk and bags to grease the drive shaft and all that and I broke a few things on the rear of the bags. Thank you.

Frank

The mold was used with the Plast-Aid polymer, and that mold was made from Silly Putty. I'm pretty sure MEK would dissolve Silly Putty - it dissolves pretty much everything, including silicone/RTV, unfortunately.

I think for molding tabs I'd try something like plaster - mold plaster around an existing tab, with waxed paper in between the two halves. Once the plaster cures, separate the two halves, then put the ABS in the plaster mold to make a replica.

But seriously, if you're going to do that, you might want to use the Plast-Aid I linked to above - you can use simple Silly Putty as a mold to capture the shape of the original tab, and then replicate it.

Thank you for the Ideas and I'm going to give that a try. Those darn tabs and all are so easy to break.
