1980 Goldwing Clutch Vibrates / Noisey at Coast / Downthrottle

Title says it all, I just got this bike, when I'm accelerating I don't hear or feel the vibrations. When I pull in the clutch it also goes away.

But on decel / coast it kinda grinds and vibrates, you can hear and feel it.

Sidenote (probably unrelated) when getting to about 6k rpms the engine cuts out like lack of fuel. Apparently pistol Pete recently did the carbs, so I'm thinking vacuum or gas cap.

That kinda sounds like a bad U-Joint.

Uh oh. Looks like it's not easily serviceable. Should I replace the entire drivetrain?

[DenverWinger]

Shouldn't be necessary to go that far, especially since parts are hard to find. You have to disassemble the rear drive to get to the U-Joint, so good opportunity to inspect/lube everything else.

New U-joints and other drive train parts are no longer stocked, but good used ones should be available. Disassembly and inspection will show you which if any parts need replaced.
