i think you need to measure the inside diameter of the engine side opening.

It's a Keihin PJ series carb. MOST LIKELY a PJ34 considering you were told it's off a 250R. Measure the "engine side" of the inside of the carburetor throat for the size. Also, choke knobs are readily available from either CPW.com or motorcyclecarbpart.com (or off Ebay) for like $10-$15.

That is one of the infamous carburetors that uses the choke circuit as the idle speed setting too. Funky to get dialed in correctly but once you do, they run well.
