I don't think the PWK will work. It is a 2 stroke carburetor, not a 4 stroke. Back in the day a lot of hop up shops used the 28mm Mikuni flat side, which is still available through places like Niche Cycle and Motorcyclecarbs.com. You'll need to get a manifold that will work with it. DG sells the 26mm Keihin PD that bolts right up to the stock manifold, although it is not a perfect match because the inside diameter of the carburetor is a bit bigger than the inside diameter of the manifold. I'm currently running the Keihin and it works well, although I wish it was a bit bigger.

The one Mike posted is the classic choice. If your feeling ambitious, a 28 or 30mm FCR is always good.

I put a 30mm mikuni pit bike carb on my 200x. It bolted up to the stock intake but it had to be port matched to the bigger carb. I also removed the choke butterfly and put epoxy in the holes that that mounted it to improve flow. I also had to change the pilot and main but it uses standard mikuni jets so that's no big deal. A lot of people are not a fan of this carb but I have had very good luck with it. The thing runs well with the carb and I haven't touched it since I jetted it so it keeps a tune. Here's a picture of it before I removed the choke.

Right now I have a line on a 28 mikuni that my uncle has, he says it's in his garage somewhere... hopefully it will work, if he ever finds it lol

I think the 2 bolt flange is the same on the 83-85 200x.

I dont think that there is any difference, just that 2 strokes need larger jets. for instance, my banshee (4 mil stroker) has 196 cc per cylinder, and has a 155 main jet. My X has 212 cc's, and it like to run on a 130 main. If anyone can prove me wrong, go ahead, I would like to learn if their is any difference.

Another thing that differs with the carb between 2 stroke and 4 is the choke system. Most all 4 strokes use a butterfly type choke, and the 2 strokes use an enrichiner, where basically it opens a valve port in the carb, and gives it more fuel. The 4 stroke butterfly closes when choke is applied, and restricts airflow, allowing it to draw more fuel. Completely different design in chokes, but it will work and improve performance with the correct jetting changes.

Catch me if you can
2 days of truck work. Tomorrow is clean up day and then I'll look for the carb, it's brand new so it's not just tossed in a box...........
Even my mind is missing.

2 stroke carb has a air screw, 4 stroke carb has a fuel screw.

That is true. However, the 2 stroke carb has been seen modified for the thumper 200X; Ask Mickey Dunlap................
