Hello and thanks for your time. :)

I just found this info:

to put this into perspective for you , Harley engines breath from both heads  they normally flow into the backing plate of the filter & then the fumes / excess oil get  sucked into throttle body & back into the fuel/ air mixture, excess oil can contain within the filter  & eventually drip , this is something that  most people fix by re routing the breather via hoses from the heads to a T piece & into the atmosphere or a catch can. I have put a small chrome filter on the end of "said hose" this is called External breathing  with out seeing your set up it sounds like that`s wot is on there now ..Hope this helps 

Get rid of the hoses, that breather is breathing through the mounting bolts directly into the new breather, did you notice the bolts are hollow?

Thanks heaps guys, just removed the hoses and it breathes through the backing plate, thanks again :)

I like the way the filter has a hole facing forward to catch the rain better and provide internal engine cooling....neat.

Who rides in the rain?

Thats the problem!  Way too many snowflakes in this generation!  I ride rain or shine, but I have to as my bike is my commuter vechicle.

Yeh, I don't ride in the rain, but Arlen Ness make great stuff and as it sits, is water resistant if you get trapped in the rain, no need for a sock :) - the forward facing hole is not directly open and cycles air back into the filter. I would recommend another filter if you are riding in the rain a lot - or a car.
