Now that I have your attention!
My (New to me) 1993 R100GS was extremely well looked after with 2 owners and only 14,700 miles.
I was wondering if the exhaust nuts have ever been loosened at all, seeing no evidence of anti-seize compound.
I have the proper BMW Nut Removal Tool and am well aware of the perils involved and when to stop turning.
My question is: Is it better to undo the nuts when they are hot or cold.
Would Thermal expansion for aluminum on aluminum come into effect?.
