Yet again, I find Black Lab Adventures did this job (on a DL650 though) several years ago, and am using the excellent writeup as a guide:
First thing I had to do was, drain engine oil and coolant.
It was time for an oil change anyway, luckily. Got the old oil drained, filter swapped, oil drain plug reinstalled. Just have to remember to refill oil at the end.
Draining coolant was, as always, a messy pain in the butt. There's simply no way to drain coolant completely. You'll always have some "ullage" that falls out when you remove the water pump cover.
I got as far as removing the crankcase cover last night.
Some notable differences between my 2007 DL1000 and Barry's DL650:
-there is a large metal wall, aka "Oil Separator," attached to the inside of the crankcase cover. I suppose it keeps oil from splashing too much on the bearings & seals that keep oil away from the coolant system, and vice versa.
-This oil separator is held in by 4 large Philips-head screws. For some reason, mine were stuck HARD. I got exactly one of them to turn with just a screwdriver.
Tried an impact wrench, need a better Phillips-head bit. One screw hread is now a little boogered up. I'm going to replace all four screws with hex-heads. Purchasing a broken screw extractor, just in case.
