i have read several posts about modifying your airbox for a cleaner more efficient intake system. does anyone have any pictures? also, where can i get a k&n filter for my 97 v90?

Some guys have take the air tube off the front of the airbox and replaced it with a piece of bent tubing to pull air from right behind the grill (look at your old tube, and it will become self explanatory pretty quickly. You can probably achieve the same effect by just cutting the goodeneck part off your stock tube. The only downside is that you'll get more crap into your airbox if you're running in full-time ram-sir mode.

The other thing to do is pull the airbox out. YOu'll see that there's a flap that switches between cold air and the warm air tubes. Turn the airbox over and you'll see a little hole under the flap. set the flap to cold air and then drive a screw up the hole to hold the flap open.
