crank case breather

[schroom]

I just bought my vmax not too long ago and I noticed it has 4 K&n filters and the oil cap has a breather hose going up to a plastic canister and it feeds into the filters. I was wondering what this is for because most other vmaxs don't have it and I kinda wanna take it off if i can.

That is part of the stage 7 setup that keeps a negative pressure in the crankcase which in turn helps the piston rings seal the combustion chamber better. Are you having issues with it?
Here is a picture of mine, but I have a Morley Muscle jet kit on mine.

+1 with redbone. but actually all maxes technically have one. on stockers, the breather tube feeds up and connects to the bottom of the airbox.
