I had a situation like that years ago on a customers bike...just a couple of questions:
1. When riding slow does the bike feel like it's weaving?
2. I know you stated but when leaned over does the bike feel like it keeps wanting to straighten up?
If you answered yes then the first thing I would check is the steering head bearings and tire pressure.
Tire pressure is pretty straight forward but as for the bearings, get the front end off the ground. The forks should fall to one side or the other under its own weight, if it doesn't rotate the forks side to side if they are rough feeling or notchy time to replace.
I had the same situation so I thought I would throw it out there.
Keep us posted
