Also be sure you have the airbox properly connected. Many times the carbs are jetted for a certain airflow and by leaving the airbox disconnected to much airflow makes them bog badly. Learned that the hard way many years back on an older 250 quad. Son wanted more performance so he removed the restricted airbox and went with a performance filter. Machine would just die under heavy acceleration, finally put the stock airbox back on and it ran fine.
