78 GS 1000 rear caliper

[2whldreams]

Restoring 1978 GS 1000 E. After installing rear rim/caliper assembly, noticed the rotor runs on the right side of the rear caliper. One would assume the rotor should be centered in the caliper. Purchased another 1978 GS 1000E and the rear rotor also runs right up against the right side of the rear caliper. It just so happens I also own a 1982 GS 1100 EZ, and the rear rotor on that bike runs in the center of the caliper. Thank you in advance for your time and attention.

running slightly off centre wont really matter, the pistons will take up any difference in side play. if it is a big difference then you have problems

It's supposed to run central. The only thing that can really affect it in that plane are the caliper mount & the wheel spacers (i.e. take some off one side & put it back on the other side in order to move the caliper relative to the rotor), those are what you need to look at...
