2010 rmz 250 wont rev

Just got the bike so i really dont know much about it. But when you start it up you cant go past 1/4 throttle or it bogs spits and sputters. It has a brand new tps i noticed and no programmer. Any ideas on what it might be? Im going to try and get a video of it asap to show exactly what it does.
