I am fitting a new pipe to my 09 fireblade which is an Australian delivered bike.

The stock exhaust has a second cable attached to it (first being the servo cable), it is electrical and seems to be a sensor of some sort. From reading other forums it is an o2 sensor I think and does not feature on USA spec blades. I have disconnected it from the stock pipe and followed the cable to as far as the engine cover near the gear lever. I can't figure out where it goes next or how to remove it. I think this cable appears on euro and UK bikes too.

My question for anyone re this cable:

1. what is it?
2. with an aftermarket can, is it safe to remove it? How do I remove it?
3. do I need an oxygen sensor eliminator plug - if so where do I plug it in.

My problem is that I have the usa tech manual which doesn't cover any of this.


Cheers
Mark

1. Its the lambda sensor (O2 sensor)
2. Some aftermarket can's have a place to reinstall the lambda sensor (Yoshi R-77 and Scorpion for example) Only remove it if you are fitting an O2 eliminator and Power Commander. It unplugs under the LHS fairing if you follow the cable.
3. See answer 2.

Reference answer 2, I'm not certain but would be fairly sure if you just unplug if, fit an aftermarket can and start it, then without an O2 eliminator it will generate an engine management alarm. If you fit a Power Commander you must fit an O2 eliminator.

What aftermarket can are you fitting?

Yes mate, it is the O2 sensor.

What to do with it depends on which aftermarkey exhaust you have bought.

What have you bought ?

Does it have a cat ?

Have you bought a PC with/without an O2 eliminator ?

Hi tully

Yep, the Scorpion has a sports cat, so the 02 sensor just goes in as per the original.

Point to note. If you are going to re-fit it, pre-twist the cable. You'll understand when you take it out :thumb:

I removed mine completely to fit the R-77 and PCV. Its a bit of a pig getting the connector plug and cable out as the routeing and clips are a "little" awkward. Pre-twisting sounds ideal but you probably run the risk of breaking the cables off the lambda sensor, how many turns is it screwed into the pipe?

I like snow but I'm starting to get a bit fed up with it. Need a couple of days rain to get rid of it and clean the roads up, then I can out to see how the bike runs with the R-77 fitted, all I can tell in the garage is that it's loud ... very loud :)

Thanks for all the replies that is awesome.

I have bought and fitted a hotbodies MGP growler. It is a stubby straight through pipe with no cat or O2 sensor bung.

I have a 02 sensor eliminator - do I unplug the o2 sensor cable and plug that in instead?

Also another question - will I need to put a power commander on it as with the new pipe it is a little rough in low rev range.

Are you currently running the new MGP Growler with the original O2 sensor plugged in but not screwed into the exhaust? Or have you fitted the O2 eliminator?

I've no experience of the MGP slip-on but my best guess would be that a PCV will be necessary because you have to do away with the O2 sensor.

Hopefully someone will be along who can give a better answer, meantime try the forum search facility as there are some posts regarding this slip-on. Just tried and came up with the link below, that has got to be massively loud :rotfl: Too much plumbing on show for my liking.

Yes the cable is still plugged in, I have a o2 sensor eliminator and I will fit that as soon as it cools down here. 44 degrees celsius today in the shade and it must be 55 degrees in my garage!

The pipe is bloody loud that is for sure. :smilebig:
