2002 R1 front end with standard wheel and calipers alignment issue

[nickodemon]

I noticed the calipers were slightly touching the discs when rotating the front wheel, so i swapped calipers with the other fazer in the garage which worked perfectly. Once i changed them over i got exactly the same issue and when i put what i thought were sticking on the other bike they work perfectly, so i want to know if there are meant to be thin spacers fitted when you fit standard wheel and discs onto a 2002 R1 front end... Also how do you know if they are sitting centre of the disc? Thoughts welcome
