I recently purchased the NO-TOIL filter cleaning agent and it hardly gets the job done. I'm curious what the best cleaning agent is for air filters. any suggestions?
I remember seeing b-mays in a lot of the amateur films when I was younger. It just sucks every time you here about something like this.

I was just curious, since OIR is no longer a sanctioned track would a B rider be able to race the A class but not have to step up to the A class in CRA or AMA?
