After I got my nuts off..........
I used a Dremel with a cutting wheel attached (damn, I forgot to put that in the tool pic
) to zip off the end of one of the chain links. Then I used the hand-dandy chain tool (also from Sum of All Parts) to push the pin out. (edit: I recommend getting a beefier chain tool that can handle 520 and 530 chains better. I snapped off a couple of the pins in the particular one I got which seems to be a better tool for bicycle chains, not motorcycle chains.
Then I put the old chain next to my new one to see how many links I should cut off. Here's where my dumbass got lucky. I should have been much more careful measuring the chain for a linkectomy. I wound up with barely
enough chain length to be squeezed on the bike with the new sprockets while maintaining the correct chain slack at full forward adjustment. I mean the chain is exactly
in spec! Lucky, lucky, lucky.
Measure, remeasure, then measure again. (Note to self: More teeth on the rear sprocket means you will need more links in your chain.
Next time, I'm just going to install the new chain and measure how many links need to come off.)
Then I took the rear wheel off so I could put the pretty blue rear sprocket on.
