Well, pulled the air box cover off. Found only a light dusting on the surface and a slight amount on the filter surface. Not enough to clean the filter but I did it anyway.. So, with the other Unifilter on top I never got anything to the airbox but with this dry type filter I am. I can either leave it alone, spray the filter with fabric filter oil and capture 90% of what it was missing or change out the filter to the TwinAir and capture 99.99%. Both of the last two options will make it tougher on the trail to service but will be the better protection and will keep me from having to service the air box filter as often where none will be true with the first option.
One disturbing thing I found was some trace dust in the intake track after the air box filter. Oddly, none was found on the inside of the filter or inside the connector tube between the filter and the rubber flange. Just after the connector...which would tell me either it's got a leak on the flange clamp or the boot/flange has a leak somewhere. I'll be taking all that apart..trust me.
