Taking off stator cover...
... left side engine cover.
I want to take this side cover off to clean out some metal shavings & replace a gasket, but I don't want to change the oil.
Am I correct that this side really has no significant oil flow?

No Significant Oil Flow
You are correct in that the left side cover (stator) does not significantly contribute to the overall oil usage of the engine unit. I see no reason to perform an oil change for such a simple task as removing that cover. You should expect a small amount of oil to drain out, a few ounces at the most. Once the repair is complete be sure to check the oil level after running the engine, just to be safe.

If your removing metal shavings... I would strongly suggest an oil change. What makes you think there's metal in your crankcase?

Thanks guys (and gals?). Spot on.
Well, previous mechanic tightened the aluminum Crankbolt Hole Cover (the big one in the middle of the left side cover) to about 100lb/ft. So I stripped the hex bolt hole trying to get it off. My friend tried several ways to get it off unsuccessfully & finally just drilled thru the cap in several places to make a slot in the cap, shoved the handle of an adjustable wrench into the slot & turned it with some vicegrips or something.
So the hole was full of metal chips & shavings. Anyway, yes, very little oil gets into this area; not even enough that a drop would come out. There is really no way for anything in the stator area to get into the crank case, but those shaving just bugged me.

That part of the engine is not sealed guys.
And oil level is gonna be oil level , all the way across the case. Its physics.
The mag stator is cooled by the engine oil also, so they make sure a sizable amount of oil exchange takes place there.
So when you crack that side cover oil will run out with a quickness.
Do like someone said earlier, and what we would do with our MX bikes,
lay the bike over 60 degrees or more and work on it without draining oil.
( tip, be careful not to damage your stator, its easier than you think )

I checked some old posts and I think L8RGYZ has been through the seized crankshaft hole cover thing before. Me too. They will seize even if they've not been overtightened. I loosen and retighten the crankshaft hole cover and the timing hole cover a couple of times a year to ensure that they don't seize.
