Bill McKenzie Posted September 28, 2019 I am planning to order a 39 mm fcr carb kit and use it without an airbox. Can someone who has done this explain what I will need in terms of adaptors, air boot?, and filter type. Thanks Bill Share this post Link to post Share on other sites
ohiodrz400sm My Rides (2) Posted September 28, 2019 The adapter for the S/SM airboot is 60.3mm (2.375"). 2.25" pod filters are common. You might find a 2-3/8" . Unless you are doing a custom type bike and more concerned with looks over performance I wouldn't recommend the pod route 1 Share this post Link to post Share on other sites
