XS650 Rear sprocket bolt circle diameter?

[shotgunjoe]

Does anyone have a rear sprocket laying around, or know the bolt circle diameter of the rear sprocket?

I am going to be making a sprocket adapter/spacer, for a future project.

Hi Joe,
I went to my unheated garage the moment it warmed up to 0ºC to get my 38T (4 speeds+underdrive) sidecar sprocket:-
Here's the dimensions, within the accuracy range of a 6" plastic vernier caliper:-
Center hole diameter 90mm
Bolt circle; 6 holes 10mm diameter on 110mm PCD
