I just bought a 1996 R1100RT with 16,000 miles on it. I drove it home - about 800 miles and it used about a half quart of oil. I used to have one of these bikes some years ago and it barely burned oil at all. I stuck a finger into the exhaust pipe and it came back with a oily/greasy deposit. I bought the bike from a 77 year old man who was using 5/40 wt synthetic. My guess is that he switched to synthetic after the 500 mile break in period. Is there a procedure that will allow the rings to finish seating themselves at this point?
