narrow band 02 sensor (NB02) mod.

RE: narrow band 02 sensor (NB02) mod.
I removed the 02 sensors and replaced them with the 330 ohm resistors and run it open loop on stock ecm. Runs rich but runs very cool. You can even touch the engine after a run. The gas milege has improved. I later added Arlin Ness air filter to lean it up a bit. I am adding slipons next week.

i just a the www.nightrider web sight and was reading about a do it yourself " how to richen a NB02 sensor" im guessing this mod. will get the bike to run a little richer making it run cooler ... it says that you can buy what is needed at a local radio shack.. has anyone tryed this mod?

The only downside to that scheme is that the adaptive fuel routines in our Delphis will see it as an error that needs correcting ("oops, my calculations based on VE are incorrect; let me add some extra fuel and change my AFV accordingly so that when I go open-loop I'll not be too lean there"). What this means is that for an open-loop area where, say, the target AFR is 13.5:1, with this modification, the fuel sent will be 13:1. If it's 12.8:1 it will be sent at a rate of 12.4:1. Maybe that's okay, I don't know...
Also, the sensors "breathe" through the wires (to get the reference oxygen content) and you want to be careful you don't mess that up (note he says it's a funny kind of wire that won't take solder). The best method would be to obtain an extra set of connectors and wiring the voltage divider into a "plug-in" segment.

Interesting you should mention a "plug-in". I just stumbled on this while reviewing Patrick's thread:
http://www.nightrider.com/parts/catalog00.htm
It's officially called an O2 Sensor Enrichment device

Thanks for the information Glens. I'm curious about this mod and there is lots to be learned.

The pre-made jumpers look interesting. For someone who doesn't care about tweaking and just wants to richen the mix a little to cool the engine down a bit, it might be the ticket. Kinda pricey though, especially when compared to the cost of making the jumpers yourself...

I view the advantage of the pre-made jumpers in terms of warranty work. If you had to take your bike in for engine or ECM problems, you could return it to stock easily.

RE: narrow band 02 sensor (NB02) mod.
I sent them a e-mail on how to get a set THAT ARE PLUG AND PLAY.A dropof half a point on the stock 14.7 to 1sounds ok to me.I will be getting V&H pro pipes,SE air cleaner,KN air filter and a dyno tune with a SERT REV G IN just few weeks. i am requesting the O2 bias set to 750 for the 14.2 to 1 AFR.Will find out what happenes when i add the NBO2 mod and drop it another half point.
