I was wondering how it would affect the engine braking. I was also wondering about the modules, if they affect the engine braking.

I keep reading that I should get one, just not sure exactly why.

What, if anything can I expect to 'feel' with this mod? Feel meaning, how's the bike going to react?

It puts more pressure on the clutch sheaves,and that means it grabs the belt tighter=less slip.

As far as the modules go,they do nothing for engine braking,not sure about the springs,it makes sense that they would.

as far as i can tell my black secondary spring hasn't affected anything other then tightening up the belt which i bought it for trust me this is hands down one of the best investments you can get for the 650
