96 750 began to get jetted at shop. He moved adjustable needles to get more fuel flow and when that wasn't enough, he said I needed another jet(I think he said main jets). Now, the bike runs worse than when I gave it to him. Stutter around 4500-5500 and hairy idle. Could it be that he took my carbs out and they unsynced? Please help. The assmunch added a whole crap load of throttle freeplay and adjusted my brakes to his settings too. Stupid service man.
