Hey, I Jet : your motor is bogging when you leave the hole (listen to the motor rpm). If you want to get real take off speed, try higher rpm though the first 50 feet. You have to keep the RPM in the power range (say 9k rpm) and split the clutch more. Give it enough gas to stay in the 9k plus range. Then you will get max acceleration. Try it and let us know how it works.
