[400>300]

May just be my eyes playing tricks on me but it seems like the bars are slightly turned right when going straight?

Yeah mine too. Loosen both the top and lower bolts and use the wiggle room to push the right bar out and pull the left bar in and tighten. That should help. In the extreme you can remove the top bolt and adjust plenty more. It is not your imagination. On my bike when I look and measure the gap between the bars ends from the tank both the left side and the right side, there is noticeably more gap on the left. The bars are not evenly set on my bike even after adjusting the wiggle room to compensate. Kawasaki is sloppy in handle bar alignment on some bikes. No other explanation.
