Calling The Graydon intake guys

[endofitall9]

alright. I built an aluminum airbox for the graydon 2 into 1 intake. it has a 35mm pwk and right now I'm running at a 148 main and a 35 pilot, needle is de k and I'm using the middle clip, for some reason it just doesnt feel right to me also the airscrew is 2 turns out and I'm running 40:1 klotz. at first I had a low end stutter and I got rid of that now it pulls nice but once in 5th and 6th it just acts like my pipes sign off.. Never had this prob before keep in mind that the reason for all this is the fact that I just bolted on the airbox.. any suggestion all the mods are in the sig. but I am not running the v3's right now I'm running boyesen carbon reeds. thanks guys
