They do, but the top one actually has the full/low markings so that was what puzzled me about the lower one.

My guess would be for racing.......I know racers who run a quart to a quart and a half LOW when racing. I would guess they fill it up to the top sight glass (normal level) and then drain it to where it's in the middle of the second (lower) sight glass.

I've heard it will help spin the crank faster if there's less oil it has to move through, but who knows

They know nothing, but I do know a guy that does know a little something about the dry clutch setups, so I sent him an email. He wasn't sure either so he sent an email to one of his friends that he was sure would know. Here's the real answer...

"the dry clutch is derived from the race course for competition only, so when they produced those parts, the upper sight glass is used to measure oil with engines that have a dry sump oil pan set-up, and the lower sight glass is used for the stock oil pan set up, so it changes the oil level with a dry-sump compared to a regular set-up oil pan, do you get what I mean by a dry-sump? oil pan. So Suzuki mass produced one style of cover with two sight glasses instead of producing two different covers, it saves on manufacturing costs just to produce one style that can be used both ways. hope this helps."

And note that in the photo of the one I posted looks like the oil level is low if you are using the upper sight glass, but okay if using the lower.

I read somewhere that it was for a quick oil check when racing.Instead of having to wait for the oil to sink all the way down,If the oil could be seen in the lower window there was enough oil in the engine.
I don't know how true this is but I will see if I can find the site where I saw the posting.I will post as soon as I find the link

I get the explanation but I am confused. I would expect a dry sump set up to use the lower sight glass - a lower level, since more of the oil would be in the oil tank. Maybe the unidentified person who explains it got it switched when he says ". . . . the upper sight glass is used to measure oil with engines that have a dry sump oil pan set-up, and the lower sight glass is used for the stock oil pan set up . . . ." ?

The dry sump oil pan was shallower hence the upper sight glass.
