Pulling to the right

Hi All,
Have searched for this one but no results, so anyone else get this?
If I sit up and let go of the handlebars at any reasonable speed, my 1100s always wants to steer to the right. I know it is an in line flat twin, but torque reaction should work the other way by pulling to the left when the throttle shuts off, opening the throttle pulls the bike to the right. I know that it has a touch of play in the paralever bearings, but the bike has always done it since I've had it despite different combinations of tyres and suspension units. My last BMW (R80) never did it and when I mentioned it to a dealer mechanic he hinted he knew the cause (but not the paralever bearings) but would not tell me, wanted the work no doubt.
So, is this actually a problem or just a quirk of the 1100s? Would be grateful if other owners let me know as this is my first 1100s.

I reckon it's a quirk - all my Boxers did it.

Do you think it's anything to do with the camber on the road??

"they all do it sir"

Can't say I agree with your thoughts on torque reaction on a closing throttle though. The crank is still turning the same way irrespective of speed. The 'lurch' to the right when you open the throttle is merely as a result of the crank speed (and therefore torque reaction) increasing. Or am I talking boxer bollox?
