Sno shark, take the small vent on the side of the plastic and cover it up until you go buy some material to cover it. When you go through the powder especially boondocking the powder comes through and gets on your clutches then they slip and your pinning it and the rubber gets super hot while it kicks in to grab. That is the rubbery mess around your clutches.
You can go to linen and things and get a fabric curtain that is just like the sock bRP used to go over the filter. Buy one, $20 buck cover all your intakes on the hood and every where else with this. I then put 4 1 1/4 inch holes in the front of my left side then 8 out the back and covered them with the curtain mess which is super fine and then placed screen door material over that to make it strong....air comes in keeping everything cool and no snow....use 5 minute epoxy to do it....this is of course after you have had all the updates. My 07 rev was slippin after the updates on the first day when i got it and when I would open the side there would be snow building up in there...went home did above work and it has ripped ever since...hope that helps...dave
