sounds like a person in a car i had to do a test drive for my company saying steering vers to the left, one the road is cambered to the left plus did you pass your test with no hands :D

sorry to be negetive on the situation just easyier to ride with hands on the bars

I've had this before on older bikes and cured it by carefully loosening the front end (axle, axle pinch, yokes, mudguard bolts etc) and yanking it as appropriate then tightening it all up then testing. Easier with a friend, free and needs caution of course but can work if the bike's had a knock. Don't undo things too much while the bike's weight is on the front end!!!

when headrace bearings are worn they bike can drift to the side as the bearing get "stuck" or sit into the pitting in the races

When I bought my bike I found I had the same problem and on inspecting found the forks were done up crooked in the yokes. So like banoffee said, loosen everything off, make sure you get it all straight, then tighten it all up.

Check that one of your brakes isn't binding also
