Got an old Honda XL250 that's not running right? This brand new carburetor from MOTO1988 might be the fix you need. It's designed to be a direct replacement for the OEM carburetors with part numbers 16100-428-671, 16100-KB7-673, 16100-428-771, 16100-428-772, 16100-428-773, and 16100-428-774. It fits specific models, so double-check this: Honda XL250S A from 1978 to 1981, and the Honda XL250R A from 1982 to 1983 (including the XL250R AC 1983). This is a complete, brand new carburetor, not a rebuild kit. Swapping out an old, gummed-up carb with a fresh one can make a world of difference in starting, idling, and overall performance for your classic bike. Before you buy, please carefully compare your bike's year, model, and old carb part number with the listing to make sure it's the right fit. Comes with friendly customer service and a 1-year product service promise for peace of mind.
