From the OP I believe he is talking about the atv/motorcycle lift (jack), not the table.
This was his question.
"Any modifications or jigs to get the lift to fit the frame of your Gold Wing?"
If it was a table, there is nothing that would have anything to do with the frame of the Gold Wing.
If the atv/motorcycle lift (jack) is what he is talking about then my answer is...THEY ARE JUNK!
I had one and gave it away.
I bought a J&S because of all the reviews,BigBird's discussion with me about his, videos etc.
I could not be happier.
You get what you pay for.
Holding up a 900# motorcycle is not the time to be cheap in my opinion.
I can explain it to you, but I can't understand it for you.
