My 07 450 hesitates when throtte cracked quickly. has been stalling too. When i look into carb, and turn the throtte, it squirts for a millisec, and is barely visible. Is this how its suposed to be? I had a ktm back in 04 that would squirt for a few seconds.. I sprayed out all the orfices related to the AP. The diaphragm looks ok to me. Am I missing something? Carb is totally stock.
