Slowly making some progress. First of all, some cleaning was in order and I didn't stop with just the engine. Since I was cleaning the pool deck I gave the frame a good going over too, being careful around the swingarm bearings and the triple tree. I got the bolts out that I could with the impact driver and just drilled the heads off of the rest. Finally got the chance to break out the Tusk case splitter tool. I alternated sides a couple of times until it broke loose. This, as I mentioned earlier, is the scary part for me.
