Red face Got me an old Goldwing

Hey guys, I been checking out the older Goldwings, found this one for $500.
It's a 1978 GL1000.
I think it's pretty clean, I heard it run for just a minute, but it has old gas in it so it hasn't run anymore since.

I'm going to get fresh gas in it, change plugs, do a compression test, see if I can free the frozen clutch cable, etc. Then I'll try to fire it up again, maybe take it for a little ride. If it seems worthy enough, then I'll probably take it all apart, clean/restore, paint, and see what suspension improvements can be made. Rebuild the brake master, new tires, a couple more bits and hopefully I can have it looking and running good for a small budget.
It also came with Vetter full front fairing, side cases, and the trunk case.

Any and all comments, advice, ideas, suggestions are appreciated! I know next to nothing about this bike.

Nice - I guess you got it fairly cheap!
I rode a CBX1000 (The 6 cylinder one) a long time ago during a VFR club visit to Germany where I switched bikes with a German owner there. A bike from around the same era. Suspension was soft and wallowy at the mere sniff of a corner and the brake woefully inadequate. So I think these things may be the first that will need attention once you have it up & running. Tires too of course.

Old fuel inside the tank is better than none!
If available, get carb gaskets / o'rings and fuel tap seals too. Take the fuel system apart and clean everything. Acetone gets rid of the varnish. I used cotton buds. The best way would be to clean with ultrasound, but you'd have to find someone with such. A carb piece clamped to something sturdy and a steam cleaner does the job - as does a jet wash...

For now, rebuild the brakes and fit braided lines if you want better feel. Brass brushes on the end of a dremmel are great for cleaning out the recesses for piston seals.

Looks like it'll be good to give it a paint job. If you get that far, then you'll probably be looking at replacing the front end with something more modern, new brakes and more.

BTW, once I do my RC51 front end conversion I'll be selling a set of reworked VFR750 forks (perhaps too short?), triples, Harris 6 pot calipers with a CBR1000 master cylinder + front wheel, discs, etc. Old technology, but it still works well. These calipers were able to lock the front wheel at 50 mph given a hard enough tug (I saved those moments), so they're still good. If they're of interest (no rush - I'm not doing this work for a while yet) I can take some measurements.

Nice score, jondog, that thing looks really clean. How many miles? You might have said in your post already. My dad went cross country on one of them beasts when he was 18! Heavy bike but decent power he said, obviously not as heavy as the new ones! His was naked too. I think they look kinda cool and retro. Great deal though man!

Just make sure you don't panic if something just "stops working"....keep close to the kill switch.

Nice find

Not sure, but at the front it looks as if it may have a timing belt... I'd change that too if so.

Nice cruiser, I just have high hopes, that this is NOT signs of you slowing down, or showing signs of getting OLD, J-Dog

After I sold the 2005 F-Boy(tractor) My intentions were to purchase a Goldwing...
My wife protested, stating "she would never ride with me on a Bagger"...
an tempted me with finding a CBR1000xx for a touring/travel bike..

Well, this is going to be a project. Discovered the gas tank is completely toast. Rust. If you knocked on it, flakes would start falling into the gas. Which now alarms me for the carbs. Worried they may need going through.
Also, one cylinder, the #4, has 25#'s less compression than the other three.
Cylinders #1, #2, #3 all test at 155psi. (On a totally cold engine - ambient temperature about 70F degrees). Cylinder #4 came in at 130.
I'm thinking leaky rings, or burnt valve, or slight possibility of a bent valve. Because of the timing belt. I haven't removed the timing cover yet to inspect the belt, but that's next on the list. Along with a valve clearance test.
What I did do is pour a little oil in the #4 cylinder then retest for compression. To discover a possible leaky ring. The compression test showed much higher, now it jumped up to about 185 psi. Confirming leaky piston rings, right?

Not sure how much more I want to put into this bike.
If my valve clearances check out to be somewhat consistent, then I'll assume the valves aren't bent, but still could have a burnt spot, contributing to my low compression. I suppose she'd run ok, but might be a bit sluggish and smokey.
Besides the compression issue and the rusted out gas tank, it needs a proper front brake master cylinder, new clutch cable, plugs, fluids, filters, tires, and a bunch of tlc.

Thinking about letting this go and sell as a parts bike?
What do you guys think?
How much farther would you go into this bike?

Seems you found Pandora's Goldwing

You should be able to part this out and get your dinero back....kinda sucks as this would be a solid ride to kick around on.
