Did you fill the oil up?before it sounded this bad, my motor made a little whine at idle nothing bad or not normal but I went riding the other day and I noticed a lot more whine and something was definitely not okay. the whining got way louder and one of my mechanic friends says it sounds like a bearing. I checked my dipstick and there was not a drop of oil on it. The sound is coming from the bottom end more on the clutch side.
