Ok so I have V&H big radius 2:2 on the bike now and had it remapped then. I recently picked up the AN big sucker air cleaner and am hearing I may need to remap again. Does anyone know if this is a definite or just a possibility?

 

What kind of air cleaner was on it before the big sucker ? if it was a stock set up then I would say yes definately need to remap. If it was a stage one then probably not

 

Stock.

 

from everything i read and laeraned over the past 2 years--you will definatley want to remap if you are going from stock AC to big sucker---the bike will be very lean (and run hot) without adding fuel to the mix somehow. how did you have it remapped before.. do you have a fule mangement system already? there are several fuel management systems out there or some follks pay the stealer for a one time download map.
