    You can buy an o2 bypass off eBay for like £10, unplug the sensor and plug a bypass in and that will do away with it?

    is the O2 is fitted to the current exhaust and has gone faulty?If so, I would buy a new one.

    If it is a new exhaust and no fitting for O2 then an eliminator as suggested and hope the fueling & the power delivery are not noticeably different

    Yes it is fitted to the new one and yes I think it's gone faulty bonjour it's flashing up as an error code but never had problems in the past till now exsaust has been on for over a year now

    I have not had to dwelve into fault code on my RR8 (touch wood!).
    O2 do go faulty but normally on cars where the heater goes open circuit. I don't think the bike one is heated. Nevertheless if you have established that's where the fault is, you should be able to get a replacement Denso which is most probably the OEM one.

    With O2, it can sometimes clear itself if you had something bad in the exhaust gases (silicon I believe is an O2 killer) but the fault code would remain. If you can clear the fault code and it re-appears again then you would be more certain.

    I am saying all this base on my experience with my car O2 sensores (2 replaced over 70000miles :()

    You could test the existing one. It involves giving volts & heat and measuring it's output. Find the details on this on the internet

    Alright bonjo well the sensor has been taken off and blanked off the bike seems like it's running well I think it's running a bit better honda told me it would cost around £100 for a new one and they never had any in stock fortunately I had already got a blanking plug and insert for the exsaust so it's not been a problem when I get the ECU remapped I think it will be good and make a big difference. The sensor it self had a broken wire on it down where it threads into the exsaust I might have a go at fixing it see if I can

    good luck buddy. As I thought the sensors don't usually go faulty unless they have been externally damaged.

    Hi John,
    Which model blade do you have?
    Do you mind me asking how you know it's a oxygen sensor problem? I am asking because I just bought a 2012 blade and when i switch the bike on, i get 2 long flashes followed by 3 short flashes. it does this a few times then the light stays constantly on while i ride. Is this the code for a oxygen sensor error?
    I have a Yoshi exhaust should I just ditch the sensor and replace with an eliminator? Anyone know if there are any negatives doing this?
    Not sure if its related but the light appeared after using ACF-50 a few weeks ago.

    Hi I have an 09 blade flakey I found out about the sensor online can't remember what site but it listed all the codes and flashes next to the problem also when I spoke to honda they confirmed two flashes and three short was an faulty sensor one of the wires was broken when I replaced the exsaust I was too rough and never turned the wires with it when I put it back on so got the plug taken off and a cap put on where the sensor went sum say u should get it checked on Dyno but it ain't affected mine but if u getting it mapped it would get checked at that point anyway which I hope to do sum time when the funds allow it probs just get the ECU mapped for mine . If u have had the exsaust on and off it have broke one of the wires honda recon about £100 for a new one that's why I just took mine off and got it blanked hope that's a bit of help for ya pal

    Thanks buddy, I'll keep looking for the error codes online but its looking like the sensor. The codes will be useful to have anyway. I think i'll get the eliminator and see how it goes, much cheaper than a replacement sensor.
