Still a lot of the old Goldwings here in the states... waiting for restoration.  I didn't restore mine for it's historical or collector value, I rebuilt it to ride.  Being a student and studying for a second career (as a geologist), I didn't have the money for a newer bike. 

The older Goldwings are a great value, especially if you're willing and able to do the restoration work yourself.  They don't have the handling and niceties of the newer bikes, but they still have just as much power (maybe more, especially the '75-'77), and are just as capable of touring as the newer one's.

Great job Axlewik . Very neat clean looking ride you have and nice  to see another older wing going strong . I myself have a 82 GL 1100 standard custom . The exhaust I used is a 19" Harley slip on muffler mated to a 77 GL 1000 hearder . Runs great , not loud but a nice low throaty tone , Plugs run light to a mediam brown , no rejeting , no throttle lag . Later Axelwik .

Zryder,

Good looking bike... the reliability and handling of a touring bike with the look of a cruiser.  I'll bet you get some double-takes.

I’m looking to replace the mufflers on my 79 GL1000.  It has the Jardine setup now but the left muffler is destroyed.  Question is, do you know if the Sporster mufflers will work with the Jardine headers and how did you hang them?  Could you maybe post a photo of the hanger you made?

 

Thanks for the grat idea.

Thanks for the grat idea.

If you look closely at the photo of the bike you'll see something at an angle, linking the top of the muffler to the passenger foot peg.  I used galvanized steel from the hardware store, about 3/4" by 3/16" cut/drilled to fit.

I think as long as your Jardine headers point toward the rear of the bike you'll be able to fit Sportster mufflers.  Take the mufflers and headers to a good automotive muffler shop and have them make an S-shape 2-3 inch offset/extension (just an offset, no change in direction) about 12 inches long.  They should be able to make the extension perfectly fit your headers and mufflers.  My local shop charged $22 to do this.

My Sportster setup has been on the bike for 10,000 miles now and I haven’t had to touch it at all.  It works well, and it’s not too loud (if you use OEM mufflers with the baffles still in place).

I see by your user name that you’re a ham.  I’m not on the air much because I’m back in school, but if you hear W7WIK give me a call.  I’m usually pounding brass at the bottom of the bands.

Thanks for the reply.  I’ve been doing some research since I posted the message and I see what you’re talking about now.  At first I didn’t realize that the Sporster mufflers had a bracket on them.  Couldn’t see one on the photos I was looking at.  Looks simple enough to do.  Thanks for the great idea. 

 

I burned the chrome off of a brand new Jardine muffler with a set of carbs off of ebay and my wife is baulking at me buying a second set.  Jardine won’t break a set and sell me one so I’ve been trying to figure something and this is just the answer I was looking for.   I’m not trying to create a showroom bike just a nice looking ride.  I’ve been having a blast ridding since I bought it.

 

Don’t do that finger talking myself.  Once I made Extra I put the key away, never did get into CW but I’m on SSTV once in a while.  Check out my web page at http://www.n5hq.com and look at the SSTV web cam.  Maybe see you on Slow Scan sometime.

 

Thanks again es 73

I like the "Finger talking" myself.  That's how I started as a novice so many years ago and it's what I'm comfortable with.  And it's the reason I got my extra ticket... more room to play at the bottom of the bands!

I've done almost all the other digital modes... Maybe someday I'll try the soundcard version of SSTV... easy enough to do I suppose.  73, Marco

They should work fine.  Just bring them (and the headers) to a muffler shop and have them make the "S" bends to keep the center stand from hitting the mufflers.

Has anyone tried this with a bagger? My 82 1100I sounds kinda wimpy and I have had to patch a gap where one of the mufflers has rusted half off.  I might still have a contact in a Harley shop to get a deal on some pulloffs.

Axelwik,
Nice bike. I have a 78 with sportster mufflers and am very happy with it.

I see that we are almost neighbors.

Bill,

I think you're the one who contacted me about the seat when I was selling my Wing a month and half ago. I've seen you on your bike.

Please tell me....What does it sound like now?  A Hondly?

A few weeks ago I was in a dilemma.  I needed a new exhaust for my ’77 GL1000.  New one’s are no longer available from Honda, and aftermarket is still pretty expensive.  Expensive to me because I’m a full-time student and money is certainly not a thing I have in abundance.

In abundance, however, is my ability (willingness) to turn a wrench.  I was an Air Force aircraft mechanic for 21 years.

There sure are a lot of very noisy Harley Davidson motorcycles on the road these days.  Most of them didn’t come from the factory that way – the owners took the stock mufflers off and replaced them with aftermarket pipes to make them belch even louder.  They call them “slip-ons.”

The Harley model that is probably most common, is the Sportster.  Sportster stock mufflers, with a little tweaking, will fit pretty well on a GL1000 (maybe others too).  Since the owners of these Sportsters no longer have a use for their OEM stock mufflers, the mufflers end up on ebay. 

I got a pair from a 2001 Sportster with 350 miles on them for $26 + shipping.  When buying them, make sure that the original baffles are still installed – some Harley guys punch them out for more decibels.  Also make sure they have mounting tabs welded on the sides… I think some don’t.

Here’s what I did.

The stock GL1000 header pipes are not an exact fit for the Sportster mufflers.  I took stainless steel sheet metal .010” thick and made shims to fit between the mating surface of the muffler and the mating surface of the header.  I used three .010” shims per side.  If I were to do it again I would use one shim of .028”.  Make sure the entire mating surface is covered (for a good air seal and clamping strength).  The sheet metal can be found at art supply and hardware stores.

For clamps I used standard Harley parts.  I got a pair for $5 from a Harley mechanic who had them sitting in his toolbox from all those “slip-ons” he installed.  New they are $8.50 apiece.

To support the weight of the muffler, I used some galvanized steel ¾ inch wide and about 3/16 inch thick and cut and drilled to size.

Re-jetting… maybe.  I re-jetted a little richer to compensate, but mostly to eliminate the off-idle glitch common with the early wings.

It sounds like the old VW bug until you open the throttle - then it's a nice not-too-loud roar.
