As far as buells are concerned...i am biased since its my first bike. But...mine has 13xxx on it. Only things that the engine ever needs is oil and spark plugs. If those get changed at the specified times, it is hassle free. If you are looking at the 1125s, try to stay away from the 08's...a couple of bugs that were not worked out until the 09's came out.
