Some oil is perfectly normal. When ridden hard, there will be more oil dripping than when putted. A 4" puddle seems like wuite a bit though. How hard did you run it?

You didn't search very well. This is a common question. Some oil dripping from the breather is normal. You may have simply overfilled your engine oil to get a drip that large.

'06 and later models are easier to over fill (they have less excess capacity) than earlier ones, and overfilling is one cause of excessive oil in the breather.
