Hi Brent,
I would guess that your motor is externally balanced if it has a 1U crank in it and this would cause big time vibrations on the back of a 390.
When you look at the back of your flywheel see if it has either a pie shaped wedge cast or machined in the surface or if it had a bunch of holes drilled in it for balancing. This would be a sign of external balancing. If there is only a few small holes it my be internally balanced.
Can you post a photo of the back of your flywheel?
I might be able to tell by looking at it

P.S. Thanks for doing such a great job as the admin of C.C.
My hat's off to you!
