    Caustic Soda

    I used to take the baffles out and fill the pipe with diluted-ish caustic soda. Bung one end with a potato. Leave it a few hours. Worked fine for me - but you'll need gloves, and wash your hands too, and wear old clothes.

    Yeah I think I've sussed out my problem.

    Air screw was set to about 1 turn. I've adjusted it out to 2 turns and changed my riding style a bit. This meant I had to reduce the idle as a consequence which means it was running fairly rich.

    Over all, this has eliminated the oily crap exiting the exhaust. So far so good.

    I read through Dangers links. Thanks heaps mate!

    i did the same thing on my old 91 kdx250 tank which is steel, it cleaned out the rust pretty good, think i used a bit much though as the tank got pretty hot ha ha ha

    KDX200's all needed rejetting for NZ, I think the factory jetting was aimed at the US market or something as are most of the bikes we get - virtually all bikes we get here whether two or four stroke will require some tinkering with the carb (jets and/or needles) to get them running properly for our conditions.
    KDX's also benefit from either removing or opening up the airbox lid (and throwing away the snorkel) as these are very restrictive. Though I would caution this would depend on where and how you ride as if you spend all your time riding through rivers etc., this may not be a good move, lol.

    PM Scott411 and he can let you know the correct jetting for the KDX with the Pro Circuit pipe (I forget it's been a while since I had one!)
    A properly set up KDX is a huge difference from the way they come out of the box.

    Interesting.
    A mate of mine knows one of the guys from Mr Motorcycles (Kawasaki/Suzuki dealer) and got in touch with them. Apparently they've sold lots and lots of KDX's over the years so should know what they're talking about.

    He asked if they needed modifying for use in NZ and if after fitting the ProCircuit system they required re-jetting etc. They basically said that they were setup fine factory and that I should check the air screw and ride the bike a bit more aggressively. So I've made some adjustments and so far so good. Typically it was fouling a plug about every 3 rides. So the next ride for me will be the true test.
    My bike is def a USA imported model as the odometer is in miles. Not sure if they are all like that or not though.

    cs363: I'll get in touch with Scott411 and see what he has to say Thanks for your advice.

    That IS interesting seeing as Scott is one of the owners of that shop!!! (Maybe something got lost in translation?!)

    When I had my KDX's the shop was owned by Mike Ramsey and Scott used to work there, lol
    It may be that they changed the jetting on later models (my last one was a '97) though I'd doubt it. Both of the KDX's I had ran Pro Circuit pipes and silencers and definitely benefitted from the jetting & airbox mods. We also ran the oil at 40:1 (synthetic oil) and the bikes ran really clean.

    Well I was standing by the guy when he rang them so he relayed the info pretty quickly. Sounds like I need to follow it up though.

    Mine is an 06. Who knows

    Lol,weird - be interesting to know what Scott tells you, keep us informed and good luck with it. The KDX is a great all rounder - heaps of fun

    Gotta agree with CS363 here Krad.
    Firstly your bike is fouling plugs every three rides so that alone is an indication it needs a bit of tweaking.
    Secondly you can have different jetting summer to winter or Sea level to taupo if you want the thing to be bang on the button.
    Changing the Pipe and silencer would definitely have an effect on the jetting if you want it to go best, not just go at all. Almost every aftermarket pipe manufacturer has alternative jetting for there pipes on their Web sites
    You also say its a US import so where from tuned for the desert, grand cannon or the coast.

    In saying the above I don't tune mine like I did my kart. It has one setting which delivers the power how I like and doesn't fowl plugs, starts every time. It has more power than I can handle so I'm happy with that. I would guess you would be happy with the same. After reading your posts you really need to get someone that can teach you how to read a used plug and make the relevant changes to to the carb.
    If you want it to go top notch read Dangers recommendations on plug reading new plugs for top performance on the other threads.

    To be honest at this point in my riding I'd be happy with jetting that is 'good enough'.

    Yeah I've read Dangers links. I don't want to start messing around with jetting unless I really have to. Bikes fast enough for my level of ability. The next few rides will be a good indicator if I need to sort the jetting out or not. Basically if it fouls another plug I'll sort it out properly

    have resent the Pm,

    most the KDX's we have sold have run fine on std jetting, but you can get them better, i run one smaller main and pilot on my own kdx's (i think that makes it 158 mains, and 45 pilots, ill check in the morning)

    run 40-1 fuel, on a good synthtic oil, we use elf 2xt. but most of the good brand name oils are fine,
