I also noticed this. It was tight.

Could this cause an issue?

The lines in the top race don't look right. Are those notches, do they have depth to them? Soak the bearings in kerosene and wipe out the races to get a better view of any wear.

They are smooth to the touch i cant feel any depth it those marks. Ill have pick up some kerosene to clean the bearings.

I think that last picture is the upper rear motor mount. There is a gap there, but the bolt is tight.

Do you guys think I should put a shim in the rear upper motor mount?

Right or wrong I don't know, but at 115K I had my steering stem bearing out a few weeks ago. My upper race had similar marking maybe not quite as defined looking. Also felt smooth with no notchy or groove type of feeling to the fingertips. Bearings felt good. I cleaned up the races, repacked the bearings and put it all back together. -- Might have been the wrong thing to do, but its what I did.

Id repack both, making sure I packed the grease in there really well, and reassemble and check, and tighten properly. The brinelling marks on the race aren't all that bad, just due to a prolonged loose stage. I don't think by eye they are bad, and if you feel no notching when tightend, should last another 30k miles...

I would suggest reading about how to test the correct torque adjustment on the bearing. As once pointed out with front tire in the air the frontend should not flop easily to either side. It should be as slight amount of tightening where you can tell the difference between the flop and not flop. How is that for technical speak.

Thanks guys! So what do you guys think about that rear motor mount? Do you think this could be causing my wandering issue?

Wouldn't hurt to shim it, but....
I don't think it is the problem as it has been that way since you bought the bike.
 I think I recall that the wandering started recently?

Yeah is started the beginning of Sept when riding out to Pikes Peak. I'm going to put everything back together, but I don't know what to check next.  I noticed when riding it a couple weeks ago it felt like a pull to the right when riding down the Highway, and its hard to turn through slower sharp corners, feels like it wants to stand up. Like there is a hitch somewhere.

I feel like i have checked almost everything, I'm staring to get a frustrated with it because its my favorite bike to commute on and the best bike in this colder weather and my girl wont ride on the back of the Ninja. ;)

Is it ok to use moly grease on the steering stem bearings? I have some left over from re greasing the rear suspension.

That should be fine, I used marine grade wheel bearing grease just because that is what I had on hand. Now I can submarine the front end :D Be prepared to check the tightness after awhile when they settle in.
