My friend just put a 450r carb on his 400ex. He wants me to jet it for him. Its got a 440 kit,pipe,filter. And my elevation is 600 feet. I was thinking maybe a 160 main. But in the directions od the jet kit it was tellin me to move something with a notch. I never heard of that so i was wondering if you guys could help me out with some info..
