The 2007 Arctic Cat F-Series models have plastic hood screens that are press-fit into the hood at various points; as snow screens up on the front and nose of the sled, and what we call the â€œknee ventsâ€. During aggressive riding, your knees can contact and knock the screens through the hood, causing them to drop down into the pan of the sled. If you catch them quick enough, you can get them before the secondary clutch (left side) or brake disc (right side) starts to notch the plastic.
The snow screens in the hood don’t seem to come dislodged as often, but busting through some healthy snow you can knock them loose as well. We’ve resorted to trying some silicone glue (sealer) to keep the plastic vents screens in place. If you have to order replacement pieces, be aware that some models use grey ones and some have black ones, so there are a couple different part numbers for each piece. We’ve heard Arctic Cat has changed the vents for the 2008s, with an improved locking design with longer tab, so for now we’re going to assume one could order and install the new-style vents. Instead of buying new pieces, you might want to glue the knee vents in place to prevent the knock-through and having them get chewed up by the drive shaft.
