Coaster installation effect?

[scott2007nomad]

I have Chuckster's coasters that I want to install but I would like to understand the mechanics behind it.

This is from Gadget's site:
"A bit of background. Reed valves are mounted on the right front of the #1 (front) cylinder and left rear of the #2 cylinder. Their purpose is to inject air into the exhaust stream immediately after the exhaust valve which causes any hydrocarbons that escaped the explosion in the combustion chamber to burn. This typically creates a popping from the exhaust when the throttle is closed and the bike is decelerating. Most riders can't even hear the explosions with stock exhaust but with aftermarket pipes the constant popping can get rather annoying."

My questions:
Where do the hydrocarbons go if they are not burned?

Could there be an adverse consequence from the coaster installation?

I currently have a TFI and V&H pipes and preparing to install Chuckster's dual plates.

Thank you.
