Did mine when I installed my 2 bros slip on and PCV - had the bike apart anyway, and only took 5 minutes and $1.50 for the rubber plug and a couple of zip ties. Used the instructions you referenced, just didn't realize from the pics that the hose is a bit hard to get to under the intake. Easy enough though, and I've had no poppping ever. Main reason I did it though - I've done the same on every bike I've owned, and they all just seem smoother that way - to each their own though. I'd recommend doing it.
