does anyone know the part number for a uni POD filter for a 2000 scrambler 400, my manual states it's a 34mm, but the filter that came in was way to large,, it stated that the i.d. was 21/4 in the rocky mountain catalog, but it was wrong, called and they said the number was correct from the order, need to know to have a clamp on filter straight to the carb......thanks.....
