GL1000 GL2 Restoration

Post by Emile »



Hi everyone,

I will soon get an old GL2 for a barn, stored by a friend for many years following an issue with alternator I think.
Hopefully I will have it in my garage in august !

I'm lin France, in Toulouse.
I guess I will have many post for the forum ! :)

Here are few pictures of the bike.

Let me know if there are things I have to look a in priority.

Welcome to GoldwingDocs!

You should probably replace the timing belts before you try to run the engine. It probably won't hurt to put a battery in and see if the starter motor can crank the engine with no fuel, the sound of the cranking can tell you if the engine still has compression in the cylinders.

If it was stored "dry", no fuel, the carburetors and fuel tank may be OK, but if it had fuel in it the fuel has changed to varnish by now, and the tank must be cleaned, and probably de-rusted. If stored "dry" you can take your chances that the carburetors may still be OK and try to start the engine. See what happens....

All new fluids, oil, coolant etc.

At minimum, flush the brake fluid. On a bike this old, probably not possible and master cylinder/wheel caliper will need rebuilt. But you might be lucky and a fluid flush will get them working good. If so, at least remove the calipers from the wheels and grease the mounting screws when re-installing. This will need to be done regardless, the front brake rotor in your pictures show the brake pads are ground down to the steel, grooves in the brake rotor... :evil:

If you can get the engine to start and run, we can test the alternator. If the stator needs replaced, the engine will have to be removed.

You shouldn't do that until the engine can be made to run, and proper tests done on the alternator.

Again, welcome, and good luck with your project! :)

I understand that one important point is to try testing alternator before removing the engine.
My plan is to remove everything if i have to paint the frame, but I can try to diagnose the engine first.
Make sense to measure compression and check alternator yes.

I guess i will fully rebuild the carbs first as i will have to do it anyway.

I have to check the documentation about how to replace riming belts.

Thanks !

I've found GL service manual with google.

SO now I see the timing belts ! I didn't know they exist on this bike :)

Bike is on the trailer !


Engine is already removed, and alternator is lost. It was in a bucket full with rust and water ^^

Not possible to test anything. I will open the engine first i guess.
