So is it fixed? What was it?
Has rear to front tire alignment been confirmed.
Steering head bearings adjusted?
Triple clamp bolts re-torqued?
Motor mounts not broken or loose?
Beads and/or wheel weights adjusted - I'd go with standard weight balancing techniques.
Rim checked for runout or a flat spot?
Wheel axle, bearings, spacers correct?
Is the tire confirmed round and not broken belts or flat spots.
Tire pressure OK?
Was the bike ever crashed?
Just a few thoughts.

Tire is new and runouts both ways is within 1/32. Bearings are new since it was an instal kit.
Weights replaced the beads and no difference in effect.
Tire pressure to spec and is new.
What readers are missing here is I could be going 100 mph shaking like a bastard to get there and as soon as I pull the clutch in, it rides smooth as glass. The tire is not the cause, nor the wheel. The pulses are getting the forks into a cycle and in turn start shaking the wheel at the axle. The extra mass on the axle is more in tune with the flex of the tubes in relation to the engine pulses from a given load and up. Keep in mind the new machined wheel is about 10 lbs heavier. My gut feeling is the fx front end is not stiff enough to tame the extra weight of the wheel.

Ron,
I would agree with you on the fork not being stiff enough an extra 10 pounds adds a ton of rotating mass. I'm not that familiar with the FX front end I ride a Fatboy. But are there any kind of fork braces available to stiffen it up? Just a thought.

There are guys on here running fatboy front wheels on the fx frony end that weights more than your rim. Just becuse the bearings are new don't mean there aren't the problem. Have you tried putting your rim and tire on anothers bike to see if it did the same? If not mybe you should. You need to start trying different things to see what happens.

Thanks for clearing up the beads/weights issue..
With the new info, your assessment seems logical.
The clutch issue seems relevant, but if all things are equal EXCEPT the new wheel, than I don't suspect an engine/tranny issue.
A test could be to pull in the clutch and then bring the throttle back up to whatever rpm you were at. I suspect though, that you won't duplicate the issue without the load of the bike on the drive train.
I wonder what new or heavier fork oil might do to slow/alter/dampen the oscillation??
Or perhaps the old school car tire trick of loosening the bead and rotating it 180*...
Random thoughts.. no real solutions..
