Has anyone used an Air Fuel Meter? I ordered the RSR Gauge. Pros Cons?

[bigchuck]

Con, it's really ugly and I'm not sure it is all that necessary. What are you putting it on?

[Ironhorse]

I had one on my 2000 Supercharged Dodge Durango R/T. It provided my air fuel ration while driving, information that I really did nothing with. I couldn't "tune on the fly" and after a while the ever changing colored lights became annoying. But that's just me.

I think an afr gauge with real time numbered read out would be more helpful than colored lights  btw how much is this kit 

[grc]

I'm thinking it would be more distracting than useful.  Why are you considering adding an AFR gauge?

I'm always of the opinion one can never have too much diagnostic information.  That's not what extra gauges are for most of us though.  Just more chit to buy/install/worry about for (usually) no particular gain nor ability to quickly remedy.  The aftermarket likes that we like this stuff though.

Bike has a Carburetor and S&S Super G and Thunderjet Pro. Just want  to be sure air fuel ratio is good as possible across the entire RPM Range.

Basically this is for tuning?

[ltank]

Yes. Tuning the Carb. S&S Super G has two fuel circuits for a wide range of rpm. Adding the Thunderjet Pro is a 3rd fuel circuit for 4800 rpm and higher. If you jet for low to mid rpm it's too lean on top end. If you jet for top end it's too rich at mid rpm.
Adding the 3rd fuel circuit makes for better air fuel ratio across the rpm range. Carburetor isn't like Fuel Injection where injectors timing can be failed in.

So you can use it to tune then once you have everything set the way you want it you could take it off?

[ltank]

Yes once everything is adjusted correctly it can be removed if wanted or leave it connected.
