Thanks for the tip off about too much oil. Sounds like the culprit.
Oil in air box?

Anybody else dump 4 quarts and go? Might have something to do with my asphalt valves.

No.
I measure it and it takes 3.7 exactly with a filter change to get the level perfect. Its only 4.1 of you can drain all of the internal passages whicb is not possible.

Well, you did say you were a lugger. I do just pour the entire 4qt jug in. . . . my light won't stay off until about 3.9qt. Aggravating traffic inspires me to keep my valves clean on a daily basis.
Yup.

I'm in the precisely 3.7 litre club. I never look at the sight glass but I do watch for 'idiot' lights, LOL!

The manual says 3.59 quarts with a filter change, and 3.28 without a filter change, so that's what I put in it. I can see quibbling with some maintenance items, but the amount of oil you're supposed to pour into an engine seems fairly straightforward.

Everyone has an opinion but mine is putting in more oil than recommended by Yamaha is not a good idea.

When I do an oil and filter change I put in about 3.5 litres.
No oil shows in sight glass but there is enough for no oil light to be on.
Take it for a quick spirited ride.
Afterwards I can just barely see moose pube of oil in the sight glass.
My OCD then forces me to add a squirt of oil and that gets me bang on!
She is a strange beast! Very particular

One would think, but my oil light will not go/stay off with that amount.
Is the moose pube more or less than an R.C.H?

If I had to overfill the oil in order to get the oil level light to go out, my bigger concern would be the accuracy of the warning light. You already know that it isn't giving you accurate information because it isn't working properly; otherwise it wouldn't stay on when you had the right amount of oil in the bike. Can you be sure it'll work properly when it's supposed to, like if you ran critically low on oil?
I think the sending unit is just a switch that bolts to the bottom of the sump, so replacement probably isn't a nightmare. It's the kind of glitch that would bug me, but that doesn't mean it would bug everyone.

Overfilling the oil just means more oil in the oil tank not in the crankcase since engine has a dry sump. Don't know why that would be a cause for increased blow by and more oil in the air box.
If it was a "normal" system, I would be more concerned. Since she doesn't use oil, being low is not a concern. To lose all of my oil would require a catastrophic failure . . . . I would probably notice that.
In general, the dry sump is a complication in the design of engines, but it is done to fulfill an objective (lower the center of gravity, increase the clearance to the ground, etc). in the same way, the minimum and maximum oil marks have a mechanically and scientifically proven foundation ... so they become a "rule" to comply with in order to be within the "safety margins" established by the manufacturer. . Exceeding those marks means riding outside of the manufacturer's specifications. In the same way, a screw could be over-tightened (no one would under-tighten it), but not everyone knows that overtightening has consequences ... that is why the manufacturer advises you on each page of the manual, the maximum tightening value of a screw. . In the same way, not everyone knows that "overfilling" or "lack" of oil has consequences.
I think the only one who knows the consequences of "exceeding the limits" set by the manufacturer... is the same manufacturer
Because the top of the oil in the sumps should be lower than things that spin, such as the crank throws and transmission gears. When it comes close and they can throw some up (or worse contact it) then oil is misted into the airspace, which goes out of those spaces through the breather.
Into the airbox.

I think in a worst case scenario, if the oil level's too high and the rotating parts like the crankshaft or transmission gears can actually come in contact with the oil, is that the oil can get whipped up into a foam and lose its viscosity. I'd guess that air being introduced into the oil by the eggbeater effects of a rotating crankshaft means that the oil pump could be pumping air along with oil, which would result in a drop in oil pressure. It would also mean an increase in heat in the engine, because the crankshaft is now dragging through some 10W-40 while it's rotating, which it isn't designed to do. Friction creates heat, and excess heat plus low oil pressure can't be a good thing for an engine.
I'm by no means an expert on the parallel twin in the Super Tenere, so maybe it's design doesn't allow the crank or transmission parts to come in contact with an overfilled oil reservoir. But those are some things that can happen to a very overfilled wet sump engine, in addition to oil ending up in the airbox.

Agreed. I changed the oil in my SECA, while I was in a hurry. Drained the oil, and then replaced it. Forgot to change the filter, but replaced the amount of oil as if I had. Rode over to a friends house. . . . got off of the bike. . . . and wondered where all the oil, that was covering the back half of the bike, came from.

Foam is right... I overfilled my Terra dry sump, but I checked within an hour of travelling after filling. The oil level is a PITA as well if you are unfamiliar with the procedure and not EXACT..
