Check the condition of the clutch pushrod rubber boot ahead of time. If it's looking bad then get a new one and replace it while you have things apart.
You'll want to get a new $15 exhaust gasket too. (K75 only) Those things are one use items. Look for a nice disco display of shiny stuff out of the exhaust from the old one when you restart the bike. ;D
It's best to drain the final drive and tranny of gear oil before removing them. When draining the tranny the stream will want to run down the center stand and make a nice mess on the floor. This can be avoided if you use some aluminum foil to aim the gear oil into your drain pan.
The bottom tranny to bellhousing bolt heads will be most likely be filled with road grime. Clean these out with a dental pick or small screwdriver ahead of time so that you can get an Allen wrench all of the way in and firmly seated so you don't strip the heads.
I've seen several spline lube write-ups indicating that you need to remove the luggage "Z" racks. Not true. Just unbolt them from the peg plates.
You don't need to remove the starter either. Just use a piece of string to hold up the rear of it when reinstalling the tranny to keep it out of the way.
When you have things apart be sure to inspect the splines of the clutch plate for "the mountain effect." See my post on
Splientology. If those show wear then you might want to consider replacing the clutch plate while you have things apart.
When putting the right peg plate back on be sure that you don't pinch the rear brake switch wires under one of the peg plate bolts.
Don't put beans up your nose. ;D
