Mine's been mayo free but the outlet was right down by the crankcase with the K&N at my last mod, so rather than have oil spill out if I wheelie I was advised on various forums to move it and so as a lock down upgrade I replaced the standard valve with a DP breather valve and extended it upwards. I'm not actually sure if the DP valve is a better part or just a dress up part which is the same as the standard plastic valve but we shall see.
