Have you tried turning the idle up any? Have you checked for a air leak yet? Does it have old fuel in the tank? And if it had old fuel in the tank did you clean out the tank before adding fresh fuel? Even if it didnt have old fuel in the tank when you got it it may off dried up in the tank or there was a crap on the sides of the tank and fuel lines that may of come off the sides of the tank when you added new fuel and a new carb but made it a dirty carb . Shake the bike around and take a flashlight and hold it under your tank and look in to the tank and see if there is crap floating around in the tank. may need some one to help out if you can hold the flashlight and look in to the tank at the same time.

What is missing at the exhaust will only make a mess. With no airfilter that can suck up crap and pebbles and jack your motor and make it run lean if set at factory settings. Try setting your carb to 2 1/2 or 2 3/4 turns out. Thats the setting we used around here for the stock carb and that where both my X2 and X7 was set at when I got both of the new. but may still need fine tuning from there
