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.

O² 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. :p

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 O² 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. ;)

So are you guys pulling the restrictive rubber air strip and unplugging the O2 sensors without installing a fuel controller? I am always leary of messing with the air intake without adding fuel with a fuel controller but I'm optimistic that unplugging the 02's will add enough fuel to offest the additional air from the removed air strip.

I really want to pull the rubber strip, unplug the O2's, and run RPW mufflers (for some sound). I would eventually put in the performance air filter and a PCV with dyno tune but I'd love to run it with the RPW's and removed air strip while I am waiting on the funds for PCV and dyno tune.

For what it's worth, I am running disconnected O² sensors, removed air strip and a set of D&D pipes. I thought this was going to be a transition setup until I can fork some money to get a PCV and high flow air filter, but I'm so happy with the setup that I think I might bypass any future add-ons.

I thought you did the stage one program? No???

Awesome! I'm glad someone else is running that setup. I thought it should be fine but I wasn't sure about pulling the air strip and running the mufflers. As soon as I get my RPW's in I will but going that route for sure. Did you feel a performance increase even without the fuel controller?

Negative. Being that California dealers offer some watered down version of the Stage 1 download, I have decided to pass on that.

I honestly did not feel a difference. Maybe because my attention's been caught by the beautiful roar of the pipes, or maybe the gains are too small for me to detect by simply riding. However, I did feel the power gain when I removed the air box strip. By no means am I advocating that the PCV is not worth having, but at a $500-600 investment, it would make it the most expensive upgrade on my bike.

That's good information to know. Like I said, I'll be going that route as soon as my mufflers arrive. I definitely plan getting a PCV and dyno tune in the future but who knows. I might end up like you and determine that it is good enough after that change. Like you said the PCV is a pretty darned expensive mod. Thanks again!

Hey Rajder, any word on when your RPW's will be arriving?

I have read where others say don't buy the vic down load. They say its a waist of money.
Spend the money and buy a Lloydz fuel programer you will get more of a benefit from a Lloydz.
Its just about the same money

No, not yet. Have you heard anything? I was going to email them about the pipes. I'm getting anxious!

This is my exact logic. I just can't justify paying money for the Vic stage 1 when you could go with a fuel controller for almost the same money and make more power and have the adjustibility. My problem is that I know a PCV and dyno tune is the absolute best way to go so I want to go that route but its considerably more expensive than the Lloydz fuel controller.

Makes a very positive difference

I just picked up my 2013 CCT. Ran the first 200 miles as it came off the showroom floor. It stalled 3 times while decelerating and coming to a stop during those 200 miles. Also would have a dip in the RPMs while coming to a stop with the clutch pulled when it didn't stall, and an acceleration lull in 2nd and 3rd. After reading about unplugging the O2 sensors here I decided to give it a try. Had the same thing going on for about the first 15 miles.....guess the computer had to acclimate......then perfect. It runs so much smoother with them unplugged. Special thanks to Crossroads for his description and photos. The front connector is a little tricky to get at. It's tucked in behind the battery.....but the whole thing took less than 10 minutes to figure out and do.
