Replacement carburetor for honda atc 200x.

[Atc 200x 1985]

Hello all, I need a replacement carburetor for my 1985 Honda ATC 200x. I am skeptical of the Chinese carburetors on amazon and eBay since are so many of them; I want one that is the OEM size, and if there is a carburetor brand/supplier that everyone on here recommends, I wouldn't care to buy that one as long as it is close to the OEM size or bigger. But if there is a place I can buy a Keihin brand carburetor that'll fit my ride, I don't care to pay Keihin price as long as it is a real Keihin.

Doesn't look like Keihin makes your original 26mm carb anymore.

That being the case, I would consider a new GENUINE Keihin PWK28mm.

Here is a link to PJ Motorsports where they give the carbs dimensions. This should help you determine if it will fit without too much fuss.

I would suggest you check any carb you are looking at very carefully. The counterfeiters are getting better by the minute going so far as to apply correct Sudco stickers, "star-K" stamps on jets, and the Keihin name cast into main body being correct, even convincingly correct packaging right down to the little card that said made in Japan.

I recently got burned on a fake PWK. Was a low volume seller and I thought it was just a regular guy that bought the carb, never used it for whatever reason and decided to sell it. It was cheaper than usual, but not cheap enough to throw a chi-com red flag. In most ways it was very convincing copy. But the carb being a 34mm Quad Vent non-Airstyker was the first flag. Keihin makes no such animal. Second was the seller stated it to be a 38mm AS. Nope. All of that to say, know your genuine Keihin carb models and the sizes and configs they are offered in. That should weed out a good many of the fake chinesium. Beyond that, let the price be your guide. If it's cheaper than it should be, it's likely a fake.

Anyway, were I in your shoes, I would be looking closely at a genuine Keihin PWK28 for your 200x.

Yep, stay away from the Chinese carbs on Amazon and Ebay. All the positive reviews are either paid for or by people who don't know what a proper running engine is. Of the one's I've bought, either the jet sizes are way off and/or the carb bodies weren't properly machined.

Use brand name (from a reputable seller with their own website) or a rebuilt OEM.


223cycles is another option for a new or rebuilt carb.

This one looks to be the real deal.

Note you can see the "Plas-tech" print on the hoses. That's also a tell tale of a chinesium carb, plain hoses.
Also, the serial number looks correct.

I would buy that carb

190 for a carburetor is insane haha. But that's the price for quality product lol. Thanks for the help

Also. since the PWK is not a stud mount carburetor, what boot/intake mount do I need to buy?

[RIDE-RED 250r]

Crap. Didn't realize you had a stud/flange mount. Apologies for giving you a bad lead.


That being the case, the suggestion to check with Mickey Dunlap (4-Stroke Tech) suggested by Shortline10 above is something I would look into.

[Atc 200x 1985]

Will do. I'm sure there's got to be something that'll let me use the PWK carb if Mickey Dunlap can't help me.

The route you're going, with a new carb, it's highly unlikely a full setup is going to be less then $100 and could very well be over $200 by the time it's all said and done.

That's just the way it is now, especially if you want someone else to do all the leg work.


If you want to save yourself some $$, look at Sudco's catalog. Page 484 will show you some options on carb manifolds, to get an idea of getting away from the stock carb configuration. There are more manifolds in the catalog, that's just to get an idea.

They also have a good page about spotting counterfeit carbs. https://www.sudco.com/genuine_vs_fake_carburetors.html

You'll likely run into fitment issues with the stock airbox tube. There were some vintage manifolds available that may have been a direct swap but you'll have to look into that. I've been down this road before and sometimes it takes a custom adapter on the inlet side of the carb to use the stock airbox. It can be a bit of a headache but pays back dividends when all sorted.

There isn't the bolt-on aftermarket performance options for the 200X like back in the day.

Absolutely don't use any Chinese rubber manifolds. The rubber they use is horrible and just about comes pre-rotted.


If you just want it to run like stock, have a stock carb professionally rebuilt. If you want more performance in every way, then go with something else. A properly matched and tuned performance carb will even make a stock engine more lively from bottom to top.


It's not uncommon for high performance carbs to be upwards of $700 on dirt bikes and modern ATVs. On a stock 200X, or even mildly built, I don't see it being even half of that but it's still going to cost.


Remember, Mickey is probably a pretty busy guy, so taking up his time cost him money. If he gives you good advice and has the parts, it'd be the proper thing to do and buy from him.

[RIDE-RED 250r]

Yep ..$190 isn't that bad at all, albeit a small carb. The price of a big PWK AS, FCR, or Lectron will really get your attention.

[Atc 200x 1985]

The price to pay for quality. Thanks for the info. I would hate to be duped and end up buying a counterfeit Keihin carb. Eventually, I plan on purchasing an exhaust and a cam for it later. I'm waiting on Mickey to respond to my email right now.

[ATC King]

While you're waiting to hear back, I done just a little bit more research that may be helpful.

I haven't confirmed it, but it looks like an intake from a CRF230 fits the XR200, which should also fit the 200X. The bend or I.D. may not be correct depending on the carb. That would allow a much wider carb selection because it's a clamp type instead of flange.

Brand new, OEM Honda part that's still available.

He said his carburetor is the stud-type mount like the regular carb, and it’s 30mm. He didn't say what brand it was. The regular race 30mm carb is 75, but there's one with a clear bowl for “race heads.” it seems to be the same, so if I am correct, the extra 50 is for the clear bowl. I guess you need the clear bowl so you can tune it easier. So with his, I get a bigger carb than the Keihin for less, and it's pre-jetted for racing.

[RIDE-RED 250r]

About the only advantage I can think of about a clear bowl is the ability to see the fuel level in the bowl.

I don't know what brand Mickey's carbs are. That price plus the fact Keihin isn't making those carbs any longer makes me think they might be Chinese, but if he is going through them and making them right I might give one a try. I'm sure he will back his product if you have issues as well, unlike buying one from amazon or wherever else.

Several years ago, my brother took a chance on a Chinese replacement carb for a 125m. It ran like crap when he first bolted it on. In his case the carb readily accepted genuine Keihin brass which he swapped in, (jets, emulsion tube) along with the original slide and needle and it ran quite good. Sometimes due to lack of options, the chi-com carbs can be helpful, especially if they will accept genuine brass. But I avoid them if at all possible. Unfortunately with some models, it's the only option.
