My bud just recvd the the Hindle exhaust. When we were matching up the b-pipe, we noticed that there was no O2 adapter.

Has anyone ran into this problem??????:confused
 
that's normal. you have to get a nut (m12 1.25 pitch) welded on to make a o2 bung. nut under a buck, weld $15. Only a few pipe manufacturers make CA model pipes w/ a bung already on.

You can also get an o2 sensor eliminator for $20 or so and remove the o2 sensor altogether, but I wouldn't reccomend that route. I think dynojet sells them.
 
Don't pay for an 02 sensor eliminator. PM DarkAngel, I think she has the resistor values ... you can just wire it up yourself for like 3$ if that's the case

Okay...but going this route...wont it foul my plugs?

What are the benefits?
 
or stop by Hare racing http://www.hareracing.com/ . grab an 02 sensor eliminator, plugs into the harness in the 02 sensor plug, left side by the idle adjustment, no need to remove the tank, just follow the wires. they are made correctly to eliminate it from the system. under $20 too.

how's the bike running after that mod? :confused
 
runs fine, I can't tell a difference. infrandom has one too.
 
Well....my buddy and my cous found a nut for the O2. They went to Midas and the installation guy welded it on for $20. Looks totally stock (what I heard). Going to see it today.

Thanks all for your input!
 
You just need a 300 ohm resistor wired in the plug and everything will run fine.
 
With my very limited mechanical knowledge, I would not recommend eliminating the O2 sensor altogether.

One of the beauties of the FI systems is the ability to monitor the oxygen level in the exhaust air and alter the fuel delivery to accomodate for it. It is not that important in bikes that are less than a couple of years old, since things are normally running fine... but when the bike is 3-4 years old and things get dirty and clogged, that is when the O2 sensor becomes helpful.

Plus, it helps lower the emissions... but of course, that is not our problem, right?

my 2 cents...

I have the same thought. I am a rotary head so my understanding of tuning is imperative.

If you have a resistor in place of the 02, then the voltage reading would be lower, introducing more fuel....rich (open-loop). That is not good...like I said, foul plugs, burnt out pistons, carbon, etc (I know, alittle extreme). I have not read up on how the Hondas' ecu react to close-loop and open-lop operation w/o an O2. I dont even know how many bits the ecu is and how many maps it is running.

If I do decide to test with and w/o an 02 sensor (using a UEGO or a regular Multimeter) I can guarantee that the bike will react better w/ an O2...under cruzing load and WOT.;)
 
Guarantee? A little confident aren't you? ;)

Here's straight verbiage from 2 reknown sources (Dan Kyle and DynoJet): The closed loop circuit has a very limited operating range, which is only in effect while holding a steady speed at certain rpms and throttle positions. In this limited area, the stock system (with or without the Power Commander) will gradually and temporarily lean out the air fuel ratio in an attempt to achieve an air/fuel ratio of 14.7:1 (stochiometric).

In otherwords, the operations of these sensors is strictly for emmissions only (unlike cars), that's why 49 state bikes don't have them. Although carbon deposits and excess HO2 is bad, it's not as bad as pinging, misfiring, or idles due to lean conditions that the stock mappings cannot account for.
 
FirebladeRR......

Taking that info from Dan is wise. He IS a wise man......

Wow...honda @ 14.7:1....that is border lining.....I guess Honda (engines) can take it.

Do the Hondas have a TPS sensor?
 
I ve done it

----You need the dyno jet plug or a 300Ohm resistor across the two white wires---
I did it both on my 929(resistor)--and used the dyno jet plug on the XX---
the O2 sensor is there for constant partial throttle leaning only---it is NOT a "closed loop" FI system-
---warning you will hear a zillion theories about this most BS---
like RR---this was all verified by Dan the man

Okay...with the resistor and the dynojet plug, are you experiencing surging during light cruzing? How about idle?
