MM is correct, no O2 sensors, but you might want to do this if you haven't already:


Hit up Helimech on here, he sells the block-off plates, or you can also get them on eBay.

Hey g00gl3it is there a chance that the my bike being for a different market has o2 sensors and I watched your video on the pair valves! Was very informative did you get a noticeable change when you blocked them off

I don't know of any 919 ever built with O2 sensors, so you should be ok.

And you won't notice any power gains (other than some small weight removal) by doing the PAIRS removal.

What you do gain is the removal of exhaust popping on hard deceleration (most notable with aftermarket pipes).

If you're on stock pipes, there really is no need to remove it. But, it's just 'one of those things' that 919 owners do

I'm on stock pipes for now ill probably end up running a single stubby carbon can alongside the swing arm with the standard headers! Would disconnecting the map sensor be detrimental to the running of the bike?

The Pairs system is not really a sensor at all. It just pumps fresh air back into the exhaust to help emissions meet requirements.

It won't hurt it at all taking it out, whenever you decide to do so, stock pipes or aftermarket.

When you do go aftermarket on the exhaust, though, you'll most likely want to do it then if you haven't, as it will help with decel pops.

And did you make the headers on your old 919 or are they a specific brand? And what your bike looked like is more or less what I want mine to look like

You can't disconnect that MAP sensor and have a bike that runs decent !
I'm not even sure if you could get it to start and run.

No sensors on NZ bikes, mate.

I'm running a PCIII and had no sensors to connect to - I think the PCV might be designed for later bikes with sensors to create a closed loop for feedback to the ECU, but not this bike - you might want to check that you're looking at the right part of the PowerCommander site.

Ok, so if it's the stuff in the illustration you are referring to, you don't need them.

New here... hi.

Ditto on there being no O2 sensors on the CB900F (even though DynoJet sell them with the PCIII!!!) I have 2 for free, except for postage, if anybody wants.

On the pair valves....

I took my pair valve out and hated the noise difference and hated the "soft feel". There is no difference in performance per se, but I do really, really like that popping from the Akras as I decelerate. It's a matter of choice, but you'll never have blue flame without the pair valves.

There is a set of covers that has the 2 indents for the valves - found on eBay (probably uk/eu sites). The solenoid plug can have a replacement female HM090 connector with 10k resistor across the terminals.

Best

Oh, and for what it's worth, the O2 sensor eliminator should be a male HM090-4 with a 330ohm resistor across the 2 pins opposite (furthest) from the lock.
