Tested on a 1989 Yamaha Radian (600).
Meatman, other factors include length of stroke, compression, flywheel mass and diameter (which I think makes the difference here), and total friction. The single was probably designed with a big flywheel to keep it idling well, and since it's less powerful it winds up (and down) less quickly. The Bandit makes more power, may have a smaller/lighter flywheel, a shorter stroke, and more friction due to the much more complex valvetrain.
Also, it could be lupus.
