nice mod job bdbanshee. i also have the k & n's on and have not had a problem with them slipping. make sure they end is free of the prepackaged oil. it can make them slip.. if they are tight it should be fine. it never hurts to double check they are on before you ride. i had to cut the air box stubs off the frame cuz they rubbed thru the outerwear. mine is jetted to 310 second notch from top. and is a perfect burn. and tank is simply zip tied to front frame. good luck.
