    Dellorto SHA Clone Review

    I recently received a dellorto sha carburetor clone for christmas. The first thing I noticed about the carburetor is that it was the almost the same size as the stock carburetor. The cone air filter it came with does make it slightly larger, and had to be bent slightly to fit, which was easy...
