Hey guys I own a 2002 400ex and when I was cleaning the carb I accidentally broke one of the ears that hold the pin for the float bowl 🙁 so I went to eBay and bought a factory take off carb off of a 2002 400ex only problem is that the one I bought only has one vent on the side and the one that came on my quad has 2 vents on the side.. Everything else looks the same, Anyone know why that is and if it’s ok to use?
