    Top Chamber

    Hello !
    As you maybe don't know it, in France, our ZRX are limited to 100hp.

    The only way to have the full power is to replace the 4 top chambers (international kawasaki ref : 16005-1057)

    ref 16005 on the picture below :

    Has someone such parts for sale ?

    They are 23 each from Cornwall Kawasaki and it would be doubtful if anyone had a set as they wouldnt really need replaced for any reason.

    It may be more economical to buy a set of used carbs or a set of CVK40`s from the ZZR1100 models.

    Take the pieces and build them skywards !

    Post a pic of the inside of the ones you have. I think that the restriction is by way of a top hat spacer machined into them that stops the slides opening fully. Should be easy enough to remove it if this is the case.

    I agree too ! And my Dremel can do the job but I want to keep the original top chambers as they are. I just want to change them.

    the cost for 4 new top chambers is about 118€ (kawasaki prices).

    Someone outside of France could probably have some that he doesn't need ?

    Re: Top Chamber

    A few days ago I've opened my carbs to check the top chambers !

    And what a surprise !

    They're not french !

    So I thought my Rex had only 106hp but in fact it has 122hp ! That's really cool !

    Next step : the Dynojet kit stage 3 !

    At this age it is a Blessing if it runs. According to statistics you would be really lucky if it really pushes 100....

    Statistically I am sure it hasn't. It's a tired iron by now. Unless you have printout to prove it....
