The 2004 FXDX Super Glide Sport I recently scored was already rockin’ a Mikuni HSR 42 Carb and a set of Thunderheaders but surprisingly had a stock air intake. Time to let the trusty Dyna breathe a little deeper thanks to an Arlen Ness Stage 1 Big Sucker Kit with a synthetic filter.
The Big Sucker has a slick design with each breather O-ringed at the heads and exiting at the mouth of the throttle body, doing away for the need of breather hoses. The Arlen Ness Synthetic performance filter is washable and reusable so I should get plenty of miles out of it. The kit comes with everything needed for a quick and easy installation.
How to Install an Arlen Ness Big Sucker Kit

2. Clean the flange on the carburetor.
3. Dab grease on face of throttle body and stick rubber gasket in place.
