Just installed my new Graydon airbox on the Raptor last night and was wondering what type of filter systems others are using for the crankcase breather hose?

I see K&N makes one but, I can't find anybody with them in stock. Any parts stores that carry breathers that will work? How about something from NAPA?

Need some help here, I wanna ride this weekend!

 

Even a Harley Davidson dealership might have one. The old Harleys used to have crankcase breathers on them. They might even have a chrome one. That what I have on one of my Harleys. Call them and see.

 

Thanks for the Harley idea ridnwarrior, I'll call a couple too see what they have.

 

Stop by the local parts store and get a small automotive crankcase breather. Slide it into the hose and zip-tie it out of the way. I used this method for a long time after hearing of a couple of guys getting sand/debris into their engine...possible from the C-case bteather. I am thinking the id of the breather hose is 3/8", but not positive.
