Gl1100 restoooooo

Postby wowimohsobored » Fri Jun 24, 2011 1:10 am



1981 goldwing restoration, so i bought this for a simple project something fun to do. This bike sat for 8 years in a storage unit. One coil was burned up and it had a bent valve so it didnt have full compression, the carburetors were pretty much trash. So when i got the bike it was only running on two cylinders and i thought it was all the coil come to find out it was also a problem with the pick up unit one of the wires had a break in it and sometimes it would work sometimes it wouldn't.

I went clear through this bike all new mechanical starting with valve job and head gaskets , new timing belts , polished timing covers.
Went ahead and ultrasonic cleaned the carburetors i switched to 83 carbs. Fully rebuilt them. Polished the intake tubes.
I put in new brakes rebuilt rear caliper and rear master cylinder. New front brakes.
New wheel bearings all around, and neck tube bearings. Also a new starter and complete new rear wiring harness from the connector at the gas tank on back , i use gm weather pack connectors for everything when i do harness work, there utterly amazing, easy to use and quite durable.
Rebuilt the front forks it was quite fun and quite easy actually. I polished up the front fork tubes and decided to finish them with a grey scotchbrite pad as it gives it a slightly dull look and will be alot easier to clean up in the long run.
I repainted the frame and swing arm and all the little parts with centari 99a black
I cleaned the gas tank with electrolysis using a jump pack and a battery charger and purex laundry detergent 14 hours later it looked brand new and the reserve gas tube was completely open.

So after setting the carbs a time or two i sealed up the back side of the vacuum advance and it runs amazing no stall off crackin the throttle.
I have the rear trunk but i opted not to put it on as i really don't like it anyway if i go on a trip ill probably put it on for added space.
I am waiting on my new tires to get here before i take it out on any kind of long trip but i have probably put 200 miles on it so far and its fun to ride, my only complaint i havent been able to get the right side valvetrain cover to seal completely maybe i need to get another set of gaskets and try again its quite annoying my boot is covered in oil ....I also wasnt willing to put a 700$ exhaust on it and in the picture the bike is runnin open headers i will post another pic tommorow possibly of it completed as i put emgo mufflers on it they are 27" long and they give the bike a deep rumble without being to loud or annoying. Contemplating what color i want to paint the bike as im not sold on the golden brown color and the paints got some defects in it as its a cheap paint job im not impressed with.. Although the bike is a driver not a show machine... I might have around 60 to 80 hours total working on the bike most of it was screwing off or waiting on paint to dry and just playin around. I am sure i have forgotten a few things and i have a bunch of other pictures but i thought these would do for now Thanks Jon

Good work on the restore. If you have 140lbs compression now I would ride it for a few thousand miles before I decided to rebuild the engine. If the bike sat for 8 years it will take a while for everything to get reseated. I'll bet the compression will come up with after some riding. Also the leak at the valve covers might be the cam shaft seal leaking and running down the side of the valve cover.

Well i got the exhaust on and the lower fairing covers, need to re adjust the valves as i have a slight tick at 3000 i can hear - 4500 above that road noise and exhaust sheild it plus im not real sure but it seems like its kinda low on power it doesnt really kick into a major power band until about 6000 rpm ? guess i should check the tourqe curves and horsepower curves to see where its really supposed to be , seems like lower around 3500 its kinda a dog. Waitin to get new tires installed this next week and i am ready to go on a trip !

I can't tell 100% from the picture, but are the pipes pushing the exhaust down or out to the side? I know more than one person has had problems with shorter HD exhausts that allow the exhaust to exit below the saddle bag instead of behind it like the OEM pipes - and if sitting in traffic, the exhaust gases can melt the bottom out of the saddle bags as a result.

The exhaust is straight down , there quite aways away from the bags , these are the 27'' mufflers they also have 32" mufflers i may go with them instead at the moment though they dont seem to be a problem with heating the bags up ?

Let it idle a while, if the bags aren't heating up, then I'd say don't worry about it!

If you are able to I would like to see some pics on how you modified the exhause to use the mufflers. I did see the Harley Exhaust on the cheap post but wondered how you did it... Thanks for your time.

I havent taken pictures of the exhaust ill try to tommorow i have been so busy with my day job (lame) i havent had a chance to do much , oh and i keep forgetting about it . Although i did have the oil leak on the right side valve cover (so i thought) it ended up being the fuel pump as someone stated, the threads were slightly stripped so a drill and a tap a helicoil later all was fine. The only thing that makes me nervous is i have a slight thump in the engine and a ticking noise that starts about 3500 rpm and goes on up from there i let off the gas and it goes away i open it slightly and it comes back with any kind of load on it, kinda annoying . I dont know if the thump is a rod or something else just being annoying. i would think if it was a rod it would be noticeable at all rpms and a slight bit more solid.
