Arlen Ness Big Sucker Question
Yes I have had the Deluxe for a whole 3 days and already looking at some mods (already ordered saddlebags from hog deluxe) . I was thinking about ordering the Ness Big Sucker Stage I which even a mechanically challenged person like myself can install. The question: is there an ECM modification required to take advantage of this mod ? I see HD sells the screamin eagle Stage I air cleaner and they say an ECM mod is required. If I have to take it back to the dealer to do this should I just buy the screamin eagle stage I over the Ness ?

The Arlen Ness filter is a K&N which is superior to the stage one filter harley uses.Harley changed the filter years back for the stage 1 .The new one they use now is known to break apart and get small holes in it that can sometimes get sucked into the motor.Unless they have changed it again?You will need some type fuel processor when changing the air filter.Go with the Arlen Ness.

Ive had the Big Sucker now for about 4 months. I wish I would have went with the Doherty. The problems ive had witht the big sucker are : The first one they sent me the backing plate cracked , now the one i have now leaks oil. They have little holes that come from the crankcase vents that are supposed to channel the oil back into the throat to be burned off . However what the oil does is run down the little channel and drip down to the bottom of the filter and eventually it will soak through and drip on the motor. I now take mine apart every couple hundred miles and wipe off the oil before it soaks the filter and makes a mess. Doherty Machine has a much better solution to this problem check them out. I will be switching to one soon. To answer your remapping question Yes you will have to remap the bike if you change the intake. Otherwise you risk running too lean . Hope this helps

Hey folks, what do you recommend in filter choices for the Arlen Ness Big Sucker... K&N and how often do you replace it? What about recharging the Ness (original filter) how often do you recharge it with the oil or liquid that they offer to for "recharging". I put the Big Sucker on my Ultra about 5k miles ago.... haven't touched it and have been happy.

I had my PCIII put on and Dyno'ed.... The download for the PCIII was very close to the final Dyno run. But I did gain a little better map and about 4 hp and 5 ft lbs of torque with the Dyno over the download PC map. The dyno run also allowed for a near perfect tune on the fuel/air mixture. Was it necessary, nope. But my bike has never run better. Cooler, more torque, more HP and it's happy ! Makes me happy ! :-)

The K&N filters just gets cleaned, not replaced. If the ness has a rechargeable filter as opposed to just cleanable, cleaning it is dependent on the miles you travel and conditions. Usually once a season under normal conditions should do the trick. You can use the K&N cleaning and oiling kits to treat the rechargeable filters that get oiled but there are some like the HD stage 1 that just get cleaned and not oiled.
I like the K&N filters for most all stage 1 units.
