Bike Talk motorcycle forum

I have an 05 Road King Custom Fuel Injected that I have just installed the following:
Arlen Ness Big Sucker Stage 1 kit; Vance & Hines Oval Slip - ons, Rev Tech DFO.
After installing this items and adjusting the DFO I am getting backfire on downshifting or if I release the throttle while still in gear. I have tweaked the DFO based on a call to Dobek but still am experiencing the problem. My current DFO pot settings are #1 = 4 , #2 = 6, # 3 = 4, # 4 = 4
My question what would be the causes for the backfire in this situation? Is it a lean or a rich fuel mixture or something different that still needs to be tweaked with the DFO?

Thanks

I have a new Softtail Deluxe and can't make up my mind to go with the Rinehart flush pipes or the Vance & Hines Big Shot longs.
I have not seen a Deluxe with the Rineharts.How do they sound?

I am looking to put a "203" cam in my 2003 Duece. Some people are telling me to do an upgrade to a 95". My question is: Is it really worth the money to go to a 95"
Thanks

I am new to this forum, so first off, Hello to everybody. I run a 2004 Electraglide Classic. I am wanting to ad an oil cooler and can remember reading about using your engine guard to do this. Has anyone here done this and have you run into any problems with this setup?
