I have a zx11 that has some knocking coming from the right side of engine case. Anyone know what it could be?

Probably good that it's not in the bottom end... but enough about that.
Could the sound be better described as a "ticking" sound?
Anyway, If I remember correctly those bikes were due for valve lash adjustment about every 6000 miles and they usually needed it.. I would check valve lash first. If you find excessive clearance that's probably the source of the noise. Not a hard job to do on that model. You just slide the rocker arm to the side then remove the shim and replace with a size that should give you the correct clearance. I don't have the spec but many times there is a sticker someplace (probably under seat) that gives the spec.
Unfortunately Kawasaki's of that era sometime ate camshafts so be sure to inspect the cam lobes for flaking and/or pitting while you have the cam cover off.
Actually the hardest part of the job is just getting to the cam cover for removal then putting it back on without screwing up the rubber gasket/s. You will likely need to replace all the "rubbers". If you get that far with it there are some helpful information about that we can discuss if need be.
