Well gents this how you fix all of your Air Filter problems: When I got my Ultra I had a Stage One installed and the stealership installed a KN filter. I liked it untill it started spitting oil on my exhaust. I then did some reasearch and found that Arlen Ness had developed a new Air Filter System call the The Big Sucker. I replaced my KN filter with this Big Suckre and have no regrets. The backing plate sticks out about a half of a inch further than the KN so you Suck more ait in to the Carb. With the PC111 on my Ultra I have had no problems with backfire when I can't use the right gas when on trips in the boonies.

YOU DO REALIZE THE FILTER ELEMENT IN YOUR NESS BIG SUCKER IS A K&N FILTER DON'T YOU? That is what my father in law is running, so I know it for a fact. It is not the K&N filter either that spits oil out on your bike. It is your head breather system! Which coincidentally, usually is run right into the air cleaner's filter housing. This is even true on the Ness big sucker. My father in law usually has had no problems with oil saturating his air filter and dripping onto his bike; but this winter the dealership that serviced his bike, overfilled the oil by 10 oz. and his Ness big sucker blew enough oil into the filter that it too dripped onto his bike.
