Interested enthusiasts may want to first check what brand of carburetor is installed on their motorcycle, but there are a few points worth paying attention to:
(1) The logos of some carburetors are not the same as those of imported ones. Different, but there is no "made in JAPAN" or no code, or the production process is rough. In such cases, they are mostly counterfeit imports. Pay special attention when buying carburetors in the motorcycle parts market.
