I started another thread about fuel stand-off spraying out of my K&N filter and getting all over my bike. 

So this Q is; Is it a practice to tune around stand-off so it's not happening in a certain RPM range?

I take it your cam has a fair amount of overlap? A different breather design with a built in mini velocity stack might be in order to contain the fog or similar breather concept. It will run a hair richer by doing that also for obvious reasons. Best I can tell you at the moment.

It's SS585. I straightened the tab mod on the TH. Never seems this b4 so maybe that will shift the stand off rpm

Entirely possible. The two are related.

I was able to find a couple write ups from "Doc" on another board which describes my situation to a T.

You might try welding a piece of rod across the pipe right after the baffle. This can break up the sound waves and solve these issues you describe in some cases
If you don't have a sense of humor you probably have no sense at all.
