Thanks, I assume you have to block up the tube on the airbox that the hose from engine vent fitted on to?

Oddjob:
If you're still using the 550 air filter yes, otherwise there is unfiltered air going into the engine intake. If you use a 500 air filter then remove the snorkel part inside the airbox and you can leave the pipe unblocked then, it's irrelevant. You may have to put something under the 500 filter as I believe the air filter housing is taller on the 550.
