    I was having trouble with my stock 200x carb even though it was all cleaned up, jets were clear, etc. I could never get my trike to idle right. Sometimes it would rev up really high, so I would turn the idle down and then it would die. I spent many hours trying to get it to idle right, and finally had enough and figured I would try one of the new eBay carbs.

    I ended up buying from this seller for $33 shipped to me. He has carbs for other Honda trikes as well: ZOOM ZOOM PARTZ. So for about $10 more than a rebuild kit you have a whole new carb. It looks alot like the oem Keihin carb and even says Keihin on it, but I doubt it is a real Keihin. It is advertised for 83-87 200x as many things on eBay are, but I doubt you could bolt it up to a second gen and have it work out of the box.

    I set the air screw to factory settings, and didn't touch anything else. I bolted it onto my 84, gave a few kicks, and it started right up and idled perfectly! I couldn't believe it. So I took it for a spin, thinking to myself yeah it idles great but how will it do actually riding. To my surprise, it runs great all through the rpm range! I couldn't be happier with this new carb. The only issue I have found with it, and I believe others have seen this with eBay carbs, is at idle if you stab the throttle really quick, you will get a bog. I was worried this would cause issues during actual riding but I never had it happen then.

    Now onto the disclaimers. My 200x is bone stock besides a rebuilt top end with .5mm over-sized Wiseco piston. I can see what others have said about re-jetting this carb for mods being a problem since there are no numbers on the jets! Just for grins I checked to see if the stock 200x oem Keihin jets screw into this carb and they do, so I guess you could get it to work with mods, but it would be hard to get a baseline.

    Note thanks to UI Vandal: There are 'C' and 'L' versions of most of the carbs. C means cable-driven choke, and L means lever choke. I didn't realize there were 2 versions when buying mine, so I bought the cable-driven choke version for my 200x even though the 200x never had this. I was able to swap over my lever choke from my stock carb, but it still works fine even with the cable-driven choke.

    Here's a couple pics:

    Says Keihin on it, but is it really?


    Any questions, fire away.

      I bought one for a 70 for 20 or so bucks but it was bigger and wouldn't run good. Maybe with exhaust and a cam it would have worked. Also the manifold bolts were further apart. But I've wasted 20 bucks on MUCH worse things so I'm not mad and I can steal parts off of it!

      That's what I was thinking when I bought this. If all else failed I would rob parts off it to rebuild my oem carb. But it works so well I am just going to stick with it.

      I just bought a carb kit for my 86 200x from Dennis Kirk and the parts in the rebuild kit were a little different from stock. It ran worse with the new kit, so i just switched back to the stock stuff after cleaning them. Chinese crap!

      My 200M does that sometimes too. It will idle so high to the point you have to ease into the first gear, and yet you take it for a ride a stop to let it idle and it will shut off. Might check this carb out if my problem comes up again.

      I rode with one of these for about a year. It was a bit rich for some reason and was hard to start. I wound up getting a rebuild kit for the stock carb and it likes that one a bit better.

      Thanks to your review I ordered the replacement carb for my ATC 185 from ZoomZoom on Fleabay.It was not the Keihin brand...but looked almost identical. I received it two days after ordering..it bolted up with minor adjustments and I was up and running in 15 minutes or less.

      After running it for half an hour or so I made a couple minor adjustments and played with the needle valve depth and ended up putting things back the way it was set from the factory because it was pretty much right on as it arrived. Spark Plug read says perfect mixture the way it was set when it arrived.

      My trike hasn't run this good in years! I believe the grand total was $33 shipped.

      It looks like there is a "Carb C" and a "Carb L" for my 200s. Anyone know the difference?

      *UPDATE* One is cable and one is lever.

      Ah ok that makes sense. I guess if I would have bought an 'L' version, I wouldn't have had to swap over my lever from my stock carb. Oh well.
