Yeah...the MAIN difference between '..all these..' and what's in an '02KDX 220 is 'they all' aren't anything that will fit in your carb.

The picture looks kinda like a PWK pilot..maybe they are..but that's not what the list is about.

Look up the PWK (what you have..a 33mm) on carbparts (I think it is) or sudco. There's a recent thread about 'where to get jets'.

You can get 'em from a dealer, too...part numbers are on any on-line fiche.

Most any bike shop will have Keihin jets..some will let you 'trade' jets, so if you buy a few of something and want to swap them for different sizes you won't have to BUY a fist full of brass.

Or call Pat's and talk to a human bean on the fone.

I called 'em...thought I'd be nice enough to tell 'em they were all screwed up.

That's something that pretty much anyone appreciates hearing, 'eh?

I'm afraid their phone-handling abilities are as good as their website maintenance.

I pressed #2 for parts information...didn't figure I'd eventually get to 'Press #456 for the HTML editing department for web content held on server farm-4'.

A couple of disjointed rings later...some silence...I went back to 'Please listen to the following menu...' crap I heard the first time.

I imagine the parts 'voice mailbox' is full, so routes to them get kicked back to where they came from...which is the NITA (Nearly InTelligent Answerer).

Honestly...I have no idea how folks as these can successfully operate a business when they cannot even run their phone system. They may well be terrific people but they need help with some basic 'stuff'...like, HOW TO ANSWER THE DAMN PHONE!

well I found what I needed. Maybe I can get some confirmation here. I need jets to fit a pwk carb. Which should be 99101-357 main jet and n424-21 slow/pilot jet right? Then what ever size I need..142 and 40. For example.. Am I on the right track? I found some pro x jets. Are these any good? Thanks again guys.. I know I am prob asking questions that have already been answered, but I search for hours sometimes and still can't find my answer. This sight has a lot of info... Sometimes hard to find

Just take your old jets to nearly any motorcycle shop and show them. They will probably bring out a whole assorted tray of jets for your carb. I've never been to a shop that doesn't stock a substantial assortment of jets. If you show em yours you can be sure to get the correct style.

Ok I will try a few shops... My local kawi dealer sucks.. I used to work for them. They don't have any jets. But our ktm shop does. I will ride by there Monday.

I put your '99..' number into google and find all sorts of places selling Keihin PWK main jets. I think the pilot is a -21 series. They are sometimes called 'long standard'. Here's the rub...not all parts on a Keihin PWK carb are the correct parts for a Keihin PWK carb...ON A KDX! The KDX slide is an 'air striker' type 'fer example.

Re: 'Am I on the right track?'

Yes. As mentioned..taking your existing jets into a shop is an excellent way to go about it if you have any question as to what style/type you need.

Pro-x jets?

That's what RMMC sells...notes them as 'aftermarket'. I don't know anything about them. I'd be leary of anything other than a Keihin jet. Why? Anecdotal history, mostly. Not all jets that LOOK the same or have the same NUMBER on them ARE the same. They (jets) are actually a quite finely made part.

I doubt it's a huge issue. Call it personal preference..but that preference is for Keihin parts.

KTM's use PWK's so you should be fine there.
