Install a Throttle Tamer.
No need to keep it above 3000 RPM. This will make it fine at all RPMs. I purchased my Glee used and the previous Owner had installed one. I have one on my ST1300 and I can go on-off throttle in corners w/ no jerkiness. Before that I had to be careful, riding 2-up in corners, as it was very jerky.
From the manufactures website:
The Throttle Tamer incorporates a non-linear ratio between hand throttle rotation and carburetor or throttle body opening. The “pulley”, or as we call it, “cam” pulls the throttle cable as the rider rotates the grip/tube. By altering the conventional, circular shaped cam, a vast improvement in control is achieved.
The Throttle Tamer has a cam with a reduced radius initially, which requires a slightly farther rotation to achieve the same carburetor or throttle body opening position as a stock throttle. This virtually eliminates the jerky “throttle snatch” especially evident in modern fuel injected street bikes. The radius increases or “ramps up” after ½ throttle to keep overall rotation requires to reach full throttle at or near stock rotation.
