Ordered a fabric rear panel for my p-2. reading the installation instructions there was a notice that says (This accessory will create the need for more frequent air cleaner maintenance. Service the air cleaner daily when operating in dusty conditions )Does anyone know why that would be? Does blocking off behind the cab create a suction in that area? Also FYI for anyone who orderd a Graphics kit they are not going to release them. I guess they have a problem with the adhesive not sticking to the rough surfaces . My Honda parts person got this straight from the Honda rep in charge of accessories. I needed to pick out something else or get a refund that's why I ordered the back panel. Thought it would help keep the dust down in the cab with my roof and windshield on.
