400EX front left wheel touching lower A-arm

Hey one and all. Been a little while since I posted here, but I had a question about something I noticed on the front end of my quad.

When I turn the bars to the stops to the right, there is ~1" between the inside of the right wheel and the back of the lower A-arm.
However, when I turn the bars to the left to the stops, there isn’t near as much room between the inside of the left wheel and the back of the lower A-arm; in fact the wheel will contact the A-arm with very little force placed on the wheel.

I’ve adjusted the tie-rods to equal length, both wheels at 0 toe. The hubs are good, the frame is great, but I’ve noticed that even when I’m traveling in a straight line, the bars are at a slight left turn. Holding them straight causes the quad to drift to the right. I tried dialing that out with tie rod adjustments, but it’s still noticeable. Any one component that could cause this?? I don’t think replacing the whole front set-up is necessary.

I should mention that it has an aftermarket steering stem (anti-vibe). I’m wondering if maybe the stem is twisted?
Anyways, that’s what I wanted to ask on here. Any and all input from the good people of this forum is greatly appreciated!
Thanks,
Ed
