    well...I have one on its way - ordered last week as I think I may have a look at fitting it - Am looking at ways of reducing some of the gubbins that adorn the bike ....looks legit - they also do an o2 eliminator kit (including Lambda blank plug)

    it would be great if you could let me know how it works for you, also any idea on the hose that goes into the valve cover on the intake side left side of motor i'm thinking it's more emissions stuff but don't want to cap it if its needed.

    I think that's the hose that gets blocked off - in the kit there's a blanking plug to put into one of the hoses - looks like that one - if there are instructions with the kit I'll scan them and post them up here ...

    OK, advise.....

    I'm in the middle of fitting a decat link pipe together with my Akropovic end can, I'm also fitting a PCV.

    I've still to wire in the PCV, which hopefully I can get done today, but so far, I've fitted the link pipe and end can and obviously removed the cat.

    I've put an O2 eliminoator on the wiring loom which leads to the O2 sensor.

    The O2 sensor i've fitted into the link pipe simply to plug the hole in the link pipe.

    I have installed for the time being a PCV map downloaded from the Dynojet website which has the following spec, Akropovic Exhaust with Link Pipe, Baffle removed, Standard Air Filters, Dynojet O2 eliminator fitted.

    My question......

    Do I really need to make this pair valve mod as well, and if I do, am I going to have to get the bike re-mapped?

    Any advise or thoughts welcome.

    you don't have to do it i'm running a Yoshi r77d no pcv and no o2 eliminator the bike seems to run fine I just get some popping and backfiring when I let off the throttle.

    Akropovic specifically state not to run the bike without a fuel mapping device such as a PCV if you remove the Cat and fit the link pipe as well as the slip on, which is the configuration I've swapped over to.
    I've also disconnected the O2 sensor and fitted the eliminator.

    Is your system a full system or are you still running with the Cat fitted to the bike?

    Any fuel mapping done to the bike? if not its a waste of time and money. unless you want to eliminate the popping with an aftermarket exhaust
