What immediately jumps out at me is the 'new' front tire...balance problems?
It's smooth as silk running straight... No bounce from the front end at all. And I know those bearings are tight.
Just had a thought though. Could it be caused by the windshield creating turbulence and slightly shaking the handlebars in a turn? It equals out to be about 2-3 wobbles per second so it's not fast like a shudder, still controllable in turns. But I feel like I need to take it very easy in the turns just in case somthing happens.
The feeling just takes away from my confidence un turns.

Have you checked the steering stem your last comment gives it away "I also feel the wobble ever so slightly right after I let of the throttle to decelerate."
When you let off the throttle your front suspension collapses a bit which makes your effective rake steeper. I'll bet your steering stem bearing is either loose or is worn. Try this:
Let go of the bars at 30 MPH but keep your hands gripped as if the handles were three inches in diameter. Now smack the right handle. Does the bike start wobbling out of control or does it wobble and straighten up by itself.
Condition one: adjust or replace the steering stem bearing.
Condition two: Steering stem is fine, keep looking for the source of the problem.

I went over the bike and made sure EVERYTHING was nice a and snug last night and couldn't find anything loose. I grabbed the front wheel and tried to see if there was any slack in the head but didn't notice any. Did the same to the rear swingarm. I'm going to go ahead a pull the tripple down and grease the bearings anyway so I'll double check them at that point. I dropped the rear suspension's spring rate down a notch as well.
So far though, it's much better. We're making progress! lol
I'd also like to know what grade of fork oil to use in these bikes, and how much should I use to get a solid, fairly high dampening rate?

Also tire pressures make sure you have enough air in both of your tires. I usually run about 24f and 35 rear but that is open for disscusion.

Steering head was loose, underwear was lost. Fixed the first of the two.
(not serious about the underwear)
