my bike will start perfectly fine however every time I give it throttle the bike shuts off. Even in neutral. When I go to first gear and slowly let the clutch out the bike also just shuts off. Any idea what is causing this? Like I can't give it any throttle or it just shut off

 

Have you had the carbs off for cleaning, as this sounds like a jet problem, have a look at this and it will explain it for you
