On a cb type engine, the oil pump is under the right side cover, which is separated by a wall if you will. oil passes between via (one or more im not honestly sure) small channels which is below the oil line in the case, and even more so in an overfilled case. That's good news because you dont need to worry about frothing stopping your pump, as that would be extremely unlikely that bubbles sink in the downward direction and into these passages
You can see the right side case, and division in this link:
Also the cb type engine has a breather port that would easily release any pressure built up in the case, so excessive pressure wouldn't be a possibility unless the roughly 14mm hole gets plugged in an extremely unusual manner.
And any seals, if any in this region, i dont see being compromised because if pressure somehow builds in the case to high levels, its likely the gases/liquids first start to blow up the pump, or even through the gaps in the piston rings before breaking through the left side out the crank/stator bearing. And you would likely know it when dark smoke starts coming out the exhaust.
Unfortunately while the larger cb's do, I do not think the smaller ones, including yours, have an oil pressure sensor, so no information can be had that way.
Frankly if there isn't excessive oil blowing out the aforementioned crankcase vent, and the oil level is not below the min mark, I do not feel you need to be concerned with the oil level, nor bother to go out of your way to check into it.
