finished the 1980 gl1100I

Postby Johnyy Smoke » Fri May 18, 2012 6:16 pm



Hello
Well after 2 1/2 months of wrenching on my bike I think I have corrected all the problems.This is a list of what I did:
Changed timing belts-the left sprocket was off by 2 teeth
replaced radiator hoses
flushed cooling system
rebuilt front forks-new seals, rings-,and installed new progressive springs
new oil seal for the tach cable at fuel pump (leaking oil)
reapolstered seat
new tires-front and back-I went with the Dunlop 404
new brakepads front and back
flushed brakes-lots of black crap-water ,I assume
lubed the final drive-both new oil and moly on the splines-and greased shaft
synced the carbs-quite the task since timing was off-then corrected
adjusted valves
fixed the neutral light-I thought the neutral saftey switch was bad-but after some investigation I found that the wire had broken at the "r tube" (which looks to me like heatshrink) I got a butt splicer and rejoined the wire-and it works like new!Even turns off when you put it in gear!.I know for a fact that this light hasnet worked for 5+ years.The motorcycle gods smiled on me with this one!
new gas filter
new thermostat-why take a chance?
new gaskets and rings for the crossover pipes-the bike had sat for "some" time as I was told.
replaced water pump-leaking oil/anti frease thru weep hole.
replaced more "o" rings then I could count.
Other than that-I didnt have much to do. :roll:
Know she runs as it was made to run.Nuff said.
None of this would have been possible if it were not for this website-and the diy articles.I sure as He** cant afford to pay someone to do all this!I would send an updated picture-but the bike looks the same-only a little cleaner.Painting will come next year.And so will a new pic.
Thanks guys.Regards,Johnyy

Go ahead and post some before and after pictures.
It's always nice to see what a bike can be restored to.

It really kinda makes you wonder how the timing belts got off by two cogs or teeth, I'm guessing the belt jumped due to them not being tight enough :shock: , or they were installed incorrectly, more than likely installed wrong...I bet it runs better now, Did you test your vacuum advance yet ? :D

The belts were installed wrong-when you relaese the tensioner-one side will rotate aprox 2 teeth because of valve spring pressure-the same amount that mine was off.It seems whoever replaced the belts before couldnt figgere out how to hold them in place.I put a wrench in place to hold the pulley in the correct position and tied the other end to the frame,replaced the tensioner and it stayed.
As for the vacume advance-as a matter of fact......I forgot all about it! :roll: So-how does one go about testing the unit?And are there any tips or tricks I need to know about before I test this?What symptoms does a bad advance have?Thanks for reminding about this!Regards,Johnyy

You can test it a few way's, the caveman way or the tech. way, both work fine but the tech way is better because you can actually see if you have a leak and how fast the leak may be...This can be fun, pull the hose off the carb and seal it[ plastic baggie rubber band or a golf tie works, start the bike, now let it idle , now suck on the hose and the engine should rev up when you do that, you are acting as a vacuum and the vacuum advance will increase the idle speed while doing that...Or another way... leave the hose on the carb pull the hose on the PG you will need a mitty vac hand pump for this test, it's the more tech way to do it, get a hose to fit the pipe on the PG firmly and pump it once and read the reading, it should not bleed down to zero, if it does you have a leak.. Check the manual for the numbers,i think it's like 3.9 " for the 80 model but check that as I'm often wrong about stuff.. :D It should stay at that reading...Now it's my personal opinion [Doesn't mean anything] that everyone with one of these older bike's should remove and inspect there PG unit and clean it up and lightly grease all moving parts, but you guys do as you wish it's only an opinion and it's a real pain in the rear to get to, gotta pull the swingarm to get to it, I can do it in my sleep now.... :D Oh and if you suck on the hose let it grab the tip of your tongue you will know if there is suction there or not..It sticks to your tongue.. :lol: Good luck..

Hello!
Well I did as you suggested-using the "cave man" method,very happy to say that the timing advance works (tho I did feel a little odd sucking on the hose on my motorcycle-no neighbors around to see me-luckily).
I have around $700 in parts after it was all said and done.I am, however going to rebuild the rear shocks,which will add another $100 to the tab.
Thank you for the kind words-I am rather proud of my first rebuild.
It would seem that the title of my post was somewhat premature-with the rear shock rebuild still to do-and I still want to paint it-original color-and I seen a cool decal for the tank the other day online,and then the steel brake lines,and man those running lights look awesome-etc,etc,etc. :lol:
Regards,Johnyy

I rebuilt the rear shocks last weekend-not to diificult at all.The left rear had about two ounces of atf fluid in it and the right about 8 ounces (as compared to the 12.34 ounces they are supposed to have).I went ahead and replaced the bush in both,and of course the seals.It really made a difference in cornering-and overall handling.I did have a slight shake in the handlebars at low speed,and this has all but dissapeared.
I would reccomend this as a standerd job to anyone who buys an old Goldwing,WELL worth the effort-kinda sets your mind at ease also!
Also refreshed the sending unit in the gas tank.Sure have learned alot.Regards,Johnyy

Well Johnyy it sounds to me like your ready for a tour man.. It's funny how it seems like a life time working on these buggers but once you have it you have it..My bike is apart right now because I'm waitng on a pulley to be made for my poorguy conversion..A 4" pulley for the crank..

Well Johnyy it is actually called the Poorboy Conversion not Poorguy Conversion but I like changing things, It's placing and mounting a automobile alternator on the exterior of the front left side of the engine, see, you will need a pulley that will fasten to the front of the crank where the timing belts live, you will have to mod. the covers to fit and make some brackets to fasten the alternator, A fella named Don P. out of Bama dreamed this up and sells a kit for the 1200's our friend Todd or RoadRogue here has posted a really neat post over at the Saunders site for the 1100's, I wanted more juice for my bike I now have 55 amps of power from the alt. I got. I am doing this mod. because I wanta add whatever I please without wondering or worrying if the bike can handle the load...I'm having a machinist here in San Antonio make some pullies up in both serpentine [3 rib] and v-belt..

O.K.
We can now add both head gaskets to the list,and while I was in there,I put in new valve seals.
500 miles later-everything is good-no leaks,smoke or any other unpleasentness.
I also installed the 12 volt to 7 volt rectifier (purchased here from admin) for the fuel and temp gauges-works like a charm.My original one was still there-all the wires had been cut, and someone had spliced in a different one from a different motorcycle!I got all the wires straightened out and all is cool now.
Keeping my fingers crossed!Regards,Johnyy

Well - once again I have "finished" the 1980 gl1100!
Since my last update on all of the repairs listed in the previous post, I have since: rebuilt the starter, installed steel brake lines, installed progressive 412 shocks, rebuilt the carbs using Randacks carb kit. I hand sanded and polished all the aluminum on the motor (timing covers, valve covers, intake manifolds).
I also painted the emblems on the side covers, per a thread on this site. I removed the "Honda" emblems on the side of the tank,as well as the "Honda Goldwing" emblem on the top of the false tank ,and filled the holes. The Honda logo on the bike was like a rolling billboard - I was never crazy about that.
"Someday" has finally come, as I finally saved enough nickles and dimes to have the bike painted!
I painted the false tank and side covers a metalic blue- The same color as our 2011 Toyota Camrey. The rest of the bike is gloss black with clear coat over all,
I reproduced the "Vetter " logo on the Farings, as well as the original pin stripeing on the tank and side covers- but in black instead of gold. It is hard to see in the pics - but it is there.
Knowing how you all love pics- I submit these for your approval , or disapproval, whichever the case may be. I did find one "before" pic taken the day I brought it home.
Thanks to all who have help me during this 2 year rebuild - without this forum - this bike would not be here today. Regards, Johnyy

Nice job on the restoration Johnny.

Bike looks fantastic.

Is it big job to replace valve seals?

No- very easy once you get the heads off. The seals are installed once the valve springs are removed. My biggest hassle was getting the carb floats dead on. I didn't realize just how precise these have to be. Regards, Johnyy

Johnyy, I have an 80 1100 set up like yours. I have replaced/serviced the timing belts, fuel lines and filter, wires and caps, radiator,thermostat and coolant, CDI boxes, flushed brakes and the list goes on. I have 2 questions for you: I have ordered a set of the stainless brake lines. Was the install easy for the brake lines? Did they improve the braking? I also plan on installing the Progressive front springs. My bike is a bear to get up on the center stand. I was told that with the new springs the ride is more controlled and the bike pops on the center stand easier. How did they work out?
Thanks
Tuna

The brake lines are fairly easy- kinda tight working conditions! They make a world of difference - Much more braking power! Getting them to bleed out is a real pain in the arse.
You cannot go wrong with the progressive springs, they also are a big improvement.
I put the springs in when I rebuilt the front forks, and progressive shocks in the rear. Feels a lot more "solid".
Both projects are money well spent. Regards, Johnyy

I was reading online about Classic motorcycle plates here in Minnesota, and it turned out that my bike qualified for them!
I went ahead and got them , as they were only $30. My regular plates were $18 a year so I will come out ahead.
Just something I thought I would throw out there. Regards, Johnyy

I decided to rebuild a set of heads myself and see if this would make a difference on how the bike ran, I replaced the heads from a 1981 with 40.000 miles ( mine has 81.000) and also lapped the valves. Put in new oil seals, valve seals and cap seal . I got a good deal on e-bay, both complete heads for $125, and so far it has worked out.
It made a noticeable difference in how the bike runs, it starts at the push of a button and valve noise is much quieter. And a bit more power. The choke is also more responsive.
Didn't break the bank either! Regards, Johnny

I got the idea for the heads from your project you posted about a couple of months ago.
A little intimidating at first, but all in all it wasn't that difficult of a job.
If only that stupid suction cup would stay on the valve :evil:. Regards, Johnny
