Sorry, no glass there. You need to pull the filler plug, and verify that it's just up to the level of the threads. If yours still has the hex head, change it to the recessed Allen - they're better at not rounding off... It's a bit of a mess to drain; put a large piece of tinfoil over the catalytic converter, and use the cardboard tube from a roll of toilet paper hard up against the drain to guide it into your waste pan. You can actually insert a socket on an extension thru the tube before you remove the plug so you don't spill. When it seems empty, tilt the bike to the right and you'll get a little more out.
80W-90 (gold/brown) seems to give better "cushioning" than 75-140 (red synth) (or whatever the weight is, I'm not in the garage right now), but the 75-140 feels more "precise" in the shifting. Don't know if anybody's published long-term results of using one against the other. 80W-90 is much preferred in the rear, seems to preserve the bearings & seals better. I like "red" in the trans just in case of a leak: the color tells you where it's coming from.

No sightglass. Put bike on centerstand and remove fill plug on right side of bike near footpeg. You might be able to get a fingertip in the hole and if you get oil on the fingertip, there is enough in the tranny.
The other way is to remove the fill plug, then remove the drain plug, drain the tranny, then refill until it overflows. Clean up the mess, then reinstall the fill plug.

No sight glass on the transmission that I am aware of. With the bike cold, put it on the center stand on a level surface, remove the fill plug and stick your finger in there and feel for the oil level. It should be just at or slightly below the bottom of the fill hole. I believe that a leak would be the only reason for a low oil level. I change mine every 6,000 miles or so and don't bother to check the level between changes.

fwiw, factory change interval for heavy fluids (trans, FD, etc) is every 12K or 1x per year. more than that is really not necessary.
