after doing the wheel bearings and having no difference I decided to order tires. When I get those in I'll mount them and see how it does. On the plus side, I did these wheel bearings in record time!

Is there any way to test that?
Was the damage to the rim on its right side, darthbane? The fender plastic looks damaged too.

There's no damage to the fender, however the lower fairing on the left side is damaged. This does coincide with the old front wheel which is damaged on the left side. I was told when I purchased the bike it was a low speed drop in the driveway and I didn't think anything of it since the fairings didn't look to be road rashed, just cracked, and the engine guards are intact and not damaged in any way.

Since you are putting a new tire on the wheel, tell the tire guy you want to have the balance of the wheel checked with no tire on it.  You also would like him to check the run out of the wheel with no tire.  Ask him if you can watch him check things out. 

Does the tire guy know you are having a problem?  If not, make sure he does.  Is he the same guy who noticed the bend in the old wheel?  Has he noticed anything on the new wheel?

Gryphon I will do that when I put on the new tire.

So far, the guy that put the tire on in the first place doesn't know I had issues with it. He mounted it, then the issues started. So I had it rebalanced (in addition to the rear) by another shop and explained to them what happened. He didn't express any difficulty in balancing it but the second shoop (that did the rebalancing) does not mount tires that were not purchased through them, they're also expensive so I rarely go through them.

When I have the new tires installed I will explain what happened and ask them to check everything.

Since you are putting a new tire on the wheel . . .
All good points, Gryph.

It's a mighty coincidence that the "low speed drop" crack and the rim damage on the old rim are on the same side.

Just to recap, darthbane, did you check the steering head bearing for play and smooth rotation, and are you certain there is an equal amount of oil in the forks as Ace mentioned? Have someone with skills inspect the bead and sidewall of the tire that was on the bent rim.

How easily was the axle extracted and inserted?

I will recheck the fork oils. I will have someone inspect the tire and rim. The Axle comes out without any issues.

Okay guys, I finally got it solved. Threw a new tire on and problem solved. The old tire was cupping a little bit and combine that with the damage done by the old rim and that is what caused it. She's ready for the season! Hopfully I'll rack up a lot more than 3500 miles this season. Thanks for the help everyone!

Phew!  I was afraid I sold you a bad wheel.
