I have an Arlen Ness Big Sucker on my 09 Ultra. I just put the FuelMoto Stage 1 AC on my wifes Superglide. I noticed that the Fuelmoto re-routes the oil breather tubes into the throttle body. My Arlen Ness blocks these tubes off. I am quite concerned now of pressure buildup. I have had this AC on for over a month now with no problems. I notice a lot of you guys run the Ness, why are the breather lines blocked off and does this create a problem later on. If so I will grab a Fuelmoto setup for my Ultra as well. Thanks!

 

No issues with mine. You'll be ok
