calipers on a -91 907, any difference in the thickness of
the discs or so? I tried a pair and the bolts fit to the fork
but they had worn out pads and the clearance to the discs
seemed close and I know that my - 91 has 300mm discs
and - 92 on has 320mm, any difference in the front mastercylinder?
Or is it a simple bolt on?
