I have a 2004 1150R. Had the same problem with the rear caliper bolt. $80 to have it removed & replaced with stainless steel bolts. Got it 12 months ago. New battery, rear & front pads, tyres, filters, ignition coils & replace plastic fantastic quick connects. But it runs ( So far). Good luck with the project. I highly recommend 4 finger shot of whiskey while looking at your bank /- balance.
