Getting ready to put on an Arlen Ness super sucker Or Inverted air cleaner on my RK do I need to worry about installing a fuel tuner right away or can it wait for the funds to get both???? Thx

 

No need to wait, an AC is not a big deal, you will be fine.

 

It will run leaner than stock when not in closed loop mode. It will run a little hotter. And you'll get some pinging now and then.

 

I did the Big Sucker Stage 2 and V&H True Duals and my bike totally leaned out. Popped all the time and totally white plugs. Went with a PCIII and fixed the lean out issue. If youre pumping more air in and out, you've got to fatten up the mixture.

 

Get a tuner!
