yfz 450 problems with cutting out mid range
Ok. I have a 05 yfz 450. I have recently installed hotcams (intake and exhaust), gyt-r slip on exhaust, aluminum air box with k&n filter. carb jetted 180 main 48 pilot needle in 4th position and 1.5 turns on fuel screw. I am having problems with the bike cutting out at mid range when cruising. I put all the parts on at once and got the jetting specs from hotcams. can anyone help me out??

Well I am running the same set up, except stock cams with the cam mod, and I run the same needle on the 4th clip, but I am only running 170 main, and I have no problems, anyone else have any suggestions, is cutting out just cruising, or when you are really on it, rich blubber sound or a lean sound,

also before I got the jetting specs from hot cams I had 170 main, 45 pilot, stock turn on fuel screw and needle in 6th position and it did the same thing. I just didnt know if maybe I got off 1 tooth on the cams and maybe that is causing it or if it is the jetting. I havnt pulled the plug yet to see what color it is yet either.
