So I bought some k&n clamp on pod filters because I had a modified airbox that the old owner had and I decided to turn it into a dune bike so I just started my build by buying some k&n pod filters and after putting them on and revving the bike a couple of times I started to here this weird type of "EWOP" noise when the rpms go lower after I rev the shee up. You can hear it better when the volumes all the way up and you have close ish to your ear, I'm using 30mm oko Carbs, I'm ported to 375cc and have fmf pipes and k&n clamp on air filters. This is my first banshee and 2 stroke so bare with me. Sent from my iPhone using Tapatalk
