Sprocket and alignment

Does this sprocket look worn out?

I'd say so. Also, it looks awful dry of lube.

Scalloped on the edges, teeth starting to bend, next time you replace the chain replace the sprocket.

To do it right you'll want to replace both sprockets and the chain altogether. Either go with OEM or these guys have nice package deals.

Curious - why the gearing change? You're going to lose some bottom end grunt and gain some top speed / lower revs at a given road speed.

I think you answered your own question.

IMHO 19t up front works great I love it. I never search for that elusive 6th gear.

I tried it and found the bike just lost that something special about it, so I went back to the stock setup.

Maybe it's getting to that '6th gear' feeling to quickly that makes it special...............

I can't tell from the photo as it's not square to the teeth. You should see asymmetric curve on the teeth....ultimately you get a shark's tooth appearance. Also, if you grab the chain halfway long the rear side of rear sprocket, try pulling the chain directly rearward away from the sprocket...more than slight movement tells you the rear sprocket teeth and/or chain is worn.
