NGK - Air Fuel Meter - Even Says it is Compatible with Leaded Fuels - at least for a short time!

 

Interesting, I was looking at the one ODP carries but havnt been able to find anyone thats using it. This one is alot cheaper but I wonder if it can take the abuse or not if left on the bike? Might be hard to find a place to mount it.

 

Didn't know ODP was offering one. . . I'll have to take a look at theirs.

If I did it, I'ld get a few bungs and weld one on to each bike and have the unit be a temp. mount. I think it is nice to always see your A/F ratio but, for what I do, I don't need it. . . be more of a tuning tool than anything.

 

Duneme,

The air/fuel wideband 02 sensor guages are pretty trick. For carbed ATV motors, you can simply look at the guage while running and get an LED readout as to your exact real time ratio for the RPM range you are in. This way you can determine a rich or lean condition in the circuit you are in. Most of the good systems will incorporate a 5 wire bosch sensor and integrate those in some sort of electronics. Depending on the electronics, you can also tap your system and get an RPM reading so that you can store logs. Once downloaded, the logs will give you A/F readings on a graph over your RPM range.
