Not having luck searching R12S A-Arm modification
 

Ebay had an RT a-arm for sale last month with what I suppose was a good starting price of less than $500. But having already bought a used R1200GS a-arm for $75 I figured I stick with it and make the modification, e.g. fill the original hole and re-machine a new one 10mm back. (and also drill for the steering dampner).

But now I can't find the thread. It preceeded the one for modifying the R1100S a-arm and Shredders a-arm swap.

Does anyone remember the thread title?

it was authored by joe the viking, here you go.

I didn't remember that Joe went a whole 13mm...too adventurous for me.

Thanks for the link
