delkevic headers 5th gen

I just got a delkevic set of headers for my 5th gen that eliminates the cat on my 2000, dont know what to do about the sensors, there is no place to plug them in.
I was thinking of bringing them in to a welding shop and have them weld in some "bungs" so I can attach them again......has anyone installed these on a 5th gen or have any ideas or suggestions for me.

 

o2 eliminators

 

For like $0.50 you can buy the two 330 ohm resistors from Radio Shack to bypass the O2 sensor. There is a how-to to do this on the VFRD board. You just plug them in and then use some black electric tape to seal it up and you are done.

 

+1 i ran with the radio shack resistors till i got a pc3... same thing as the dynojet eliminators and worth the money...

 

I brought the headers in to have the bungs made up out of stainless at a machine shop and welded into the new stainless headers, I figure this bike has a computor on board that honda paid a lot of money for r and d that came with the bike, I might as well use it, after speaking to several bike mechanics they all agreed that the computer and o2 sensors should compensate for the diffrent pipe ( shorty delkevic) and new headers that eliminate the cat. Let you know how it turns out when I get to ride it in the spring again !

 

You might still get some FI issues and your light come on. If you do, you will need to use some O2 eliminators. At that point you will also need to plug the bungs you had welded in. Just make sure you use the correct size bolt in both diameter and length so that all it does is plug the bung, not the pipe.

 

the o2 sensors that come with your bike are narrow band o2 sensors. they only measure oxygen content at steady throttle ie cruising and idle. they will not compensate for performance modifications. they are only there to further lean out the air/fuel ratio during cruising for better gas mileage. for performance modifications you need to adjust the air/fuel ratio with a POWER COMmANDER. with the power commander o2 sensor eliminators are necessary.

you guys are confusing the narrow band o2 sensors that this bike comes with, with wide band o2 sensors (that can compensate for performance modification) that come with cars.

also they read the exhaust before the catalytic converts so they have no idea whether the cat is in place or not.

 

I have heard that the bike actually runs better without the O2 sensor...... Anyone want to confirm this?

 

well leaning out is good if you want throttle response, and not much of a performance mod, just freeing up the exhaust ,and puting a k & n filter( more air in more air out) and I guess I will just have to see how it works if not I will have to go with the o2 eliminators and power comander, but I belive the o2 sensors still work at any speed and even thou they were ahead of the cat, they read O2. the O2 measurement will now be changed without the cat. and I am hoping they will compinsate for this.............. thats all the power comander does but at a pre determinedO2 setting, mine wil be variable.....or at least thats what I am hopping for............. but I appreciate anyones input, thoughts and ideas !

 

" thats all the power comander does but at a pre determinedO2 setting, mine wil be variable.....or at least thats what I am hopping for............. but I appreciate anyones input, thoughts and ideas ! "

then get a power commander 5. a pc5 will actually do, every thing that you are hoping that the stock o2 sensors and ecu do.

 

yes it runs better with out the o2 sensors. it stops a lot of the low speed surging that plagues these bikes in stock form.
just be sure to do the 99 cent o2 eliminators, or cough up the dough for the dynojet o2 eliminators...

 

Where on the board do i find this

 

I know there is a how-to on the VFR Discussion - Home site, do a search for 330 ohm resistors or 300 ohm

 

Here is the link to it on VFRD: Make Your Own O2 Sensor Eliminators - VFR Discussion

I just did this over the past week and his instructions are spot on except for one thing. He doesn't mention cutting the leads on the resistors down. I trimmed my leads down to roughly half an inch and bent them at 90 degree angles to the resistor. This lets the resistor sit flush with the connector when you plug it in. You can then tape it in place with electrical tape and it will not budge one bit and is very secure.

Make sure that you get the 330 ohm 1/4 watt resistors. I had to try a few Radio Shack's to find them because nobody had the 1/4 watts in stock. Others on various forums have used different wattage resistors and had mixed results. I have not been able to find a single report of someone having problems with the 1/4W ones though.

 

Search, WTH is that? You mean look for it yourself, come on man that would take to much work.:crazy: <-- Heavy on the sarcasm

:focus:

 

lol well said...

 

ok so I am not good with the computor!....but I found it......on another site
