Just bought a 2008 Ultra this year with 3200 miles on it. A week after I had it, it started to over heat and run rough. I took it back to the dealer and had them look at it. To make a long story short, they over filled the oil in the bike. They fixed that but it seems like the bike runs rougher now. Would over filling the oil effect the crankshaft run out? With being a new owner of a Harley, I don't know if it is just me. At idle the bike does shake quiet a bit to what I am used to. Any advise?
