i just purchased a 04 trx450r and its all stock the problem im having is when its idiling and youy goose the throttle it hesitates or dies like not getting enough fuel i took the carb apart and it has all the stock stuff somebody help me i would like to ride but cant thanks

 

Have you taken the spark plug out and checked the color white means not enough fuel black is too much the best is a golden brown color on the electrode. And also when you goose the throttle how long had the engine been idling because if you had not warmed the engine up that will happen with mine too.
