    That first carb the needle was lumpy but it was just a build up of junk I think ..... Ill look at it closer after it gets the ultrasonic boom

    Re the tapered headers, I was just too lazy to do it that (correct) way. I might have to do that version for a side to side comparison, if and when I get my bike together. The ZXR sounded good the last time Grey started it, so this project has light at the end of the tunnel.

    I have waited for a few response of our friend Grey's shift to the dark side???? To me this is a positive step into enlightenment and as Blair put it......light at the end of the tunnel :thumb_ups: Feel certain those carbs will be sorted promptly and the engine will be purring away nicely :D
    Having played with the ZXR's over the years, I've come to like them a lot. They come equipped with some good gear(forks) and the cool pool vac hoses..... gotta love those ;) Will be watching this thread closely....good luck Grey or should I say "KwakaGrey"

    Sure do, the MC22 has them as well and they are awesome. Having said that my Bandit has the same carbs as your FZR and they are performing OK so far.

    Just a suggestion Mr Grey. Spray the engine with WD40, it will soak in while you are doing other things and help to shift all the corrosion and grime.

    Bandits are not downdraft (BST rather than BDST) so they avoid the complexity of the jet housing seals and do not have gravity pushing the needles into the emulsion tubes. Most of the wear of these two parts seems to be occurring when the engine is at idle. You can see this by all the pics that owners have posted. Obviously, this is the point at which there is minimum clearance between the needle and the emulsion tube, but that is only half the story; the other half is that when the idle mixture and/or synch is incorrect the slides, carbs and the engine will vibrate which accelerates wear on those two critical parts. The more they wear the more difficult it becomes to get a smooth idle and so the cycle becomes self perpetuating. If we could get a video of Grasshopper's slides at idle and compare that to another FZR that has a lumpy idle it would illustrate this clearly. It is so important that idle mixture is set correctly but unfortunately most owners rely on 'n turns out' which is, at best, just a starting point.
    cheers
