Default who on a stock XC disconnected O2 sensor?

I'd like your feed back please if you didn't alter pipes, air box, filter or anything and only disconnected O2 sensor. Please provide feedback on not only performance but mpg, noise or and Pro/Con to this alteration.

Thanks.

I was getting some stalling when traffic lights turned green. Disconnected the O2 sensors and it all but went away due to stronger idle. Used to get 50 mpg on highway, now get 46-47 due to richer mixture - which is a good thing. A lean mixture makes for hotter running. No noise difference and no cons.

Default OČ disconnect

I second everything RICZ just said. I've had the stalling problem also, which has gone away. There is no noise difference, just a healthier running engine. Only draw back is that the bike's not as eco friendly as a Prius, but if I was and environment worshiper, I would've gotten an electric bike.

Please add your bike's year and model to your signature. Here's why.

Now that they told you about disconcerting the 02's you should know what it does is doesn't allow your ECM to control your fuel.
Follow the little thin wire back to the connectors and un plug them.
Ride a good tank full of gas and see what you think if you don't like it hook them back up and be on your marry way.

I did both air strip and O2's, just ran my first tank of fuel thru and I got better fuel mileage. Just be careful if you remove the rubber strip to watch the fuel line to make sure it recesses back down in the frame or else you will snap the fuel line off of the fuel pump and that costs $300 to replace.

To get the little air strip out from under the tank its actually really easy. Only have to move the tank back about 3-4 inches. Just grab the top of the foam strip and pull it out. Then slide the tank back up. Don't even have to lift it up really. O2 sensors aren't bad either. In total it only takes about 5 minutes to do both.

Origionally I started this thread for no air box, stage one or pipe alterations, but I see it is gravitating to a new subject so I don't want to spoil the fun. Lets now assume you do the sensor disabling, if you remove the rubber seal don't you get air intake noise without drowning it out with music or loud pipes? Isn't that was it there to stop?

I did both because I did not care what the sound difference was. But in doing so, I barely noticed the sound from the air box. I ran a full tank of fuel thru yesterday and I got better MPG (from 39-42 to 45) as well.

But I also removed the silencer ring on the turbo of my Dodge Cummins P/U engine as well just for the sound.

Yes, more noise but also more power as the bike is starving for air. It's your choice but to me the bike is way too quiet stock and the power difference is very noticeable.

KevinX has said our bikes run at their leanest limit from factory. Disconnecting the OČ sensors allows your bike to run a little richer, thus cooler, thus preserving engine life. Search the forum for KevinX's posts on the matter if you wish further back-up for this. You may disconnect the sensors and leave the rest of the bike stock.

Agreed. And the air strip removal is a reversible procedure, just in case you miss the muzzled up effect for your pony. Give it a try, and see how you like it.

Btw, if you knew your exhausts have a whine bottle cork in them, so the bike's quieter, would you not remove them to see what's it like to ride it uncorked? It's the same story with this strip.
