Surely nobody really thinks altering gearing makes more horsepower!

Only adding stickers adds horsepower.

Correct Mickey, you would think it would remain unchanged, but to lose over 2 LB FT of torque on top is surprising with -1 +2 which is a common change.

The red ones have more HP.

The red ones have more HP.

No need to be stating the obvious

The red ones have more HP.

Sorry, you got it wrong, only the Spencer blue ones have more HP

OK OK have a laugh at my expense, I can take it!! Wait till your sleeping at the rally and I change your gears

No worries. My bike sleeps next to me in bed. Please don't judge me.

As to the original article... there isn't a horsepower change when changing sprockets, but you are changing the way that horsepower is applied. With a lower gear ratio you get to use more of that horsepower off the line, and a higher ratio gives you a higher top end speed. that is assuming that you have enough horsepower to handle the higher gear ratio.

I dreamed last night that someone stole my bike and the insurance company bought me a 2014 DLX. I liked the six speed! Woke up grinning and my wife hit me. Not sure what she thought I was dreaming of...
