Hey guys. I am riding an 07 and here are some pictures of my air box and filter after a 60 mile dusty ride. I have already ground down the cage post to allow the filter cage to seat tighter. Here is ther thread on that throry http://www.thumpertalk.com/forum/showthread.php?t=576888&highlight=dust+carb I am using a Twin air filter with generous amounts of oil. Do you guys think there is a leak in the air box around the boot? Where is the dist coming in? Another picture shows this fine dust on the inside of the AIS hose elbow. Could there be a bad seal here, where the elbow meets the boot? Also a thought is the dust seemed to really be concentrating on a small spot on the filter, enough to cover the lettering completely. maybe it just got over powered and seeped though the filter a bit? Let me know what you think.
