    That's enough to suck some unwanted air in from the atmosphere. Hope that's your idle problem as it was mine because it's such an easy fix.

    Hmmm, well that was half a day i won't get back.
    Had to pull the the intake manifold off to get access to fit clips on the feed hose between the IAM to the manifold.
    All back together and it is one step backwards - now once it warms up it goes up to 2500rpm and stays there. Blipping the throttle no longer reduces the revs. Just tested in the garage so far, won't get a road run in today as have had a couple of beers to commiserate.
    Will also check that i haven't dropped an o-ring on the manifold but there are no obvious gaps.
    It is fascinating working on a fuel injected bike after all these years, but fascinating will turn to rewarding if progress is actually made.

    Blipping never worked for me. Once hot and RPM up there, it stayed there. Occasionally if I turned the motor off and restarted it would go down for a bit. Sounds like you do have a gap somewhere. I find, because there is so much pressure on the flange from that bent stiff house from the airbox is what causes the flange to go slightly cockeyed.

    Read all the other threads on this topic. Hopefully it will help trigger a fix.

    True. I'm sure there is more than one cause for this pain in the ass phenomena. I'm just happy mine was an easy fix...…...so far.

    Have been talking with the factory and the new NZ dealer, since my ECU was remapped for the shorties (just after it seems) there were further software updates made available which my bike doesn't yet have. It's a 2 day ride to the new dealer, but fortunately our rally this year is just around the corner, so will be going a day early for a tech session.
    In the interim taking the bike our for a short test ride has in part helped, at the first stop sign it was hunting from 2000 - 2250rpm on quite a short cycle, by the time i got home again it was idling below 1500rpm but running up to 2000rpm briefly then dropping back down, which will make it rideable.
