WHEN IN MOTION, AT VARYING CONSTANT SPEED, AS THROTTLE IS OPEN AND HELD AT ABOUT 10%, MOTORCYCLE ENGINE WOULD BUCK ON AND OFF REPEATEDLY UNTIL YOU EITHER ACCELERATED OR CHANGE GEAR. THIS IS A VERY DANGEROUS BEHAVIOR WHEN GOING AROUND A CURVE AS THE ON OFF SENSATION IS VERY ABRUPT AND CAN UNBALANCE THE HANDLING OF THE BIKE. *TR

"HERKY-JERKY" IS WHEN FUEL SHUTS OFF AT 1-5% THROTTLE, NOT 0%. THEN IT DOES NOT COME BACK ON UNTIL 5%+ THROTTLE. IT IS IMPOSSIBLE TO HOLD A STEADY THROTTLE BETWEEN 1-5% THROTTLE NO MATTER WHAT GEAR OR WHAT SPEED. *TR
ABRUPT ON/OFF THROTTLE CAN CAUSE SUDDEN AND UNEXPECTED RAPID DECELERATION AND ACCELERATION, DESTABILIZING THE VEHICLE POTENTIALLY LEADING TO LOSS OF CONTROL AND A CRASH. THE PROBLEM SEEMS TO OCCUR AT LOWER ENGINE RPM'S (4,000-7,000 RPM) AND SEEMS MOST PREVALENT AT HIGH ENGINE TEMPERATURES 200+ AND ESPECIALLY WHEN THE VEHICLE IS TURNED ON AND STARTED WHILE AT HIGHER TEMPERATURES. *TR
