What GII says is true.
Road riders drop their yokes down the forks to steepen the steering angle and give a faster turn-in on corners.
Dropping the yokes also pitches the whole bike forwards and puts more weight on the front, which reduces the tendancy to wheelie when hard on the throttle. Look at a drag bike, those guys use tie down straps to compress the front suspension and get as much weight over the front as possible.
As for the bike wanting to tuck-under, a steeper steering angle inherently reduces stability...
I say if your happy with how the bike feels, dont worry about it. If not, you can always experiment with the height of the yokes until you find something thats good for you.
