Maybe get someone else at the track to do a lap on your bike to see if it feels weird to them.
A bad headset could be the problem, but a wonky headset would feel weird at any speed on a banked surface. It sorta feels like riding on deflated tires or if your wheel were in a crack in the road.
It could be a technique thing where you are tensing up when you go fast.
