83 200x Carburetor upgrade

[Traveller88]

I am needing some advice on what size carburetor I can put on my 83 200x. I would prefer one that bolts directly. If I have to buy additional items to modify how it attaches. Thanks for information

The 200X carb is 24mm. A XR200 carb is 26mm and is a direct bolt on as long as you change your jetting over to it. That is a carb from a XR200 that only has one carb. Some had two I believe. You can go bigger on carb size, but that isn't a performance upgrade in itself. It takes a highly modified engine to require more than a 26mm carb. I was running a 200X carb on my AutoX. I switched to a XR200 carb. There wasn't any more power after the swap. All it did was change the power characteristics of the engine. I lost a slight bit of power down low, but gained a slight bit on the very top end of the RPM range. Probably nobody besides me could even tell the difference.
