Anti-Seize is your friend when working on motorcycles, so lube the Output shaft, retaining plate and bolts.
Slip the sprocket into the chain.
Put the sprocket onto the shaft.
Install the retaining plate then turn it to where the bolts line up,
You may need to rotate it 180 degrees because the 2 bolt holes have a different PCD.
Tighten the bolts and re fit the sprocket cover.
Refer to page 63-65 of the owners manual for adjusting the chain, but make it 30-35mm slack in the the lower half of the chain midway between the sprockets.
Before (14T sprocket.)
After (13T sprocket)
Moved it exactly one mark.

Nice photos. The same procedure applies to fitting a 15T front sprocket with the additional step of trimming the nubs from the plastic sprocket cover so that the metal guard piece can be positioned all the way forward against the bolt holes to make sure it doesn't rub.
Cool, man. How's the clearance of the chain on the swing arm afterwards? It sits pretty close with the 14T already. What are your thoughts on the issue? I'm doing the 13T swap this week.
Awesome. I can't wait. Hopefully I won't have time to consciously think "wow, I have time to think about watching the tach climb to redline at WOT" in 2nd gear as I'm watching the tach climb to redline at WOT. That, and achieving my goal of being able to say "way to get up that slight incline on the interstate without dropping speed or downshifting, little bike."
Anyhow, thanks to you guys here and the superbike shop where I live, I'll be making the switch with no hesitation.
Changing the front sprocket.
