You probably are going to fast. You may want to let the clutch out between gears. Brake sooner. If you feel like you are entering the turn too fast, you probably are. Brake sooner and more gradual. You should be able to roll on the throttle through the turn. Get your self into a parking lot with some green tennis balls cut in 1/2 (as cones). Go to the range where you trained. There are 4 left hand corners painted there, if you ride counter clockwise.
