So...what DID you know about this bike before you bought it? yes, its air cooled, and no its NOT carburated.
What don't you like about the mid-range torque? I mean, that is what everyone raves about the 2 valve motors (you did know the bike only has 2 valves per cylinder, right?!?!?)
BTW, make sure you get the thing serviced (oil AND valves) every 6k.
