I remembered a couple more.
When installing the transmission in your truck, it's possible to put the oil in the transmission through the hole the stickshift goes in. However, if you don't want a big bunch of gear oil on the floor, put the driveshaft in the transmission before filling it. Also, and this is important, don't let your helper pour that oil in while your face is right under the tail of the transmission trying to put the driveshaft in. Gear oil in the eyes is most unpleasant.
When the dash lights on your KLR go out, before removing the fairing, gas tank, seat, battery, and exposing the entire wiring harness to see where it has shorted, check to be sure that you haven't just burned out all three dash bulbs. Especially if you really hammered it over a bump the day you noticed your dash lights were out.
Last but not least, when you install lifting links on your KLR, adjust the headlight BEFORE you ride it to work, and then ride it home from work in the middle of the night. Especially if you are like me, and live about ten miles past the last street light. That bright spot five feet in front of the bike doesn't really help.
