Yep, I didn't think you'd like it.
Apart from the influence that you describe, I also found myself having to drop 2 or even 3 gears for a corner to get engine braking.
If you do decide to swap your gearbox, the only additional thing to that thread of mine to be aware of is the shimming of the transmission shafts to stay in spec.
Axial clearance: 0.01 - 0.13 mm. I found the Adventure's shafts were a smidgen looser than the Dukes.
I often wonder where that road goes? And that, has usually made all the difference. Appologies to Mr Frost
