Rebuilding my 81 gl1100.

Post by Pellet44 » Mon Dec 31, 2018 3:46 pm



Hi
My first gold wing rebuild, need some advice.

Bought it for $100 was told it had a Knock in the engine and looked pretty rough, but for $100 didn’t expect anything less.
Had to lift it Onto the truck by myself (not easy) .
Hooked up the jumper cables and put some fuel in it and it started but the Knock was pretty loud . Checked the valves and took off the carby and cleaned it. New oil , filters etc and tried again and even rode it around but the knock was still there.
I split the engine (again not easy) and found some wear on pretty much all the bearings and the crank shaft has some damage .
I want to know if it is salvageable I would like to rebuild it and if anyone could give me a good guesstimate on what sort of money I’m looking spending that would be great . I’m trying to add some photos and got a vid of the “knock “

My engine had a bad knock and finally gave up the ghost. I got a very good engine from a salvage yard in Wisc for $600.

Get a used engine and if you want dig into this engine and get it fixed then sell it. Getting a different engine will allow you to ride in a week or two. It will take you a while to get all the parts together

Looking at the bearings and journals, it looks like this engine has been run out of oil at some point. There is severe friction and heat damage to both bearings and journals as well as the crank. It looks like one of the bearings might even have been spun.

Even if you had the journals and crank machined, replacement bearings are going to be pretty much unavailable. I'd say bite the bullet and find a replacement engine, because it would cost you several orders of magnitude more to fix this one.

If I was to replace the engine again for my 83-I. I would replace with an 80 engine.Better torque and power with the 80 engine.

80 or 83 engines are plug and play. The hardest part of engine removal is that damn cir clip on the drive shaft.

That circlip was a bitch it actually just fell apart once I got hold of it.
As it stands I’m looking for a new motor.
But the damage is only light on one of the crank shaft journals for the no1 piston.
Can I get away with just smoothing it out?
And can I get new bearings?
