I am worried I may be running too rich though, Without an Intake 50% is probably a better setting
Nightrider states on their website that you will lose about 6% in MPG with their products. It only makes since that if your running richer then 14.6:1 you will lose MPG. The EPA mandates 14.6:1 because that is the AFR that creates a complete burn of the gas. Going richer and you don't get a complete burn and some fuel gets blown out with the exhaust.

I have no real knowledge because I have not used them and have seen no dyno comparisons, but seems they can only operate in closed loop and adjust/fool the fuel ratio the fixed percent of the resistor. If that is all ya want then I guess they work???

Ive had them on my Ultra almost since day 1. They work, Ive played with the Vieds up to 75% and down to 25%. At 75% my bike seemed sluggish and I could smell fuel, at 25% the bike ran better, but had a bit of popping on decal. Ive left them set them just under 50% for over a year and all seems good. 2 points of note, I never really noticed and difference in Temp. and my fuel mileage never really changed from stock. I run 4 Rineharts, decatted head pipe, stock breather, no other engine mods. Hope this helps.

Now that I have FL-VIED-10 installed, is it pretty wide open as to what air filter/breather I can put on? I'm not a fan of the football a/f and would like a round filter with cover or similar set up.
