I have heard of at least two people here over the years who lubed the input shaft spines on an 1150GS, put the bike back together and had the exact same symptoms. It turns out that when putting the final drive back on, the FD input shaft slipped and did not engage the rear end of the driveshaft so the driveshaft was not connected to the FD. It can happen. Not saying that is what happened to you at all, but it is one possibility that has been reported with the same symptoms and something to consider. If you don't come up with any other explanation, pull back the FD boot, rotate the back wheel and make sure the driveshaft rotates before pulling the transmission all the way off to recheck the clutch.
