Ok, this proves to be PITA Z1 does not carry those. I got 2 last plugs from local Autozone. Need 2 more and no local stores have them.
Seems like B7ES aka 1111 discontinued?

As far as I know yes, but not actually discontinued but replaced. The B7ES is now a BR7ES. Resister plug now. I was able to order some through NAPA

After reading this I just ordered some ND W24ES-U plugs off ebay. It sucks that the old style removable top plugs are being discontinued.

I've been using ND W22ES-U spark plugs in my KZ650 for the past 13 years and have found them to work better in my bike than the NGK plugs I previously used. Ed

You can buy NGK caps meant for a terminal nut instead a terminal stud.

Thank you. Very useful info. The problem with the plug is they are superseding the non-resistor plug to a resistor plug. The new BR7ES plug is still available in removable terminal nut but will not be usable with the existing resistor caps. I don’t understand the resistor concept but read that some resistance helps increase spark strength. But if you stack resistance then you diminish spark.

Katit had originally purchased a solid terminal B7ES from ebay.
In that situation a different NGK plug cap would work.

The B7ES is still available but in a larger spark gap version (1.1mm vs .8mm).
You just have to tighten the gap and use a different spark plug cap as it's a solid terminal spark plug.

Correct to address the OP. We got off typic chasing plugs as the correction.

Thank you for finding the replacement non-resistor plug. Why or what is the reasoning to go to Nickle? I also see the 2311 is a solid nut. So to continue to use the NGK we would have to swap in new caps.

No worries katit.
I somewhat enjoy the research and seeing what solutions are available.

Mikaw,
Yeah, essentially you would swap caps. They twist on so it's not too much trouble.
Below is NGK's explanation on different metals they use.
