I have a 400ex with dmc alien pipe(sounds awesome!)rev kit on the way,.080 over(426),13-1 je piston, port and polish head and intake, white brothers race cam,FCR carb and wondering what jets are the rest of you running with the race set up and did you do away with air box and use clamp on kn or what?
i think mine has a 165 main in it now. seems a little fat. i have air box lid removed with kn and outerwear. Anyone else out there with
similar set up, cam,compression?
