Default 2007 Fat Boy Engine Noise

Need Advice. 2007 Fat Boy has only 250 miles on it. When running the engine sounds like it has a massive vacuum leak. Or it sounds like a car's defroster on high. Is this normal? Listening to other 98 cu.in. bikes of same year, this noise is not present. Others say it may be the primary chain. Is this a documented problem? Thanks for any feedback.

Amsol motor oil made mine much quieter.

With the mileage and year it should be a warranty issue.
What does the dealer say?

The dealers are hiding from this issue on these bikes. My 07 Heritage sounds like a sewing machine with marbles jumping around in it. I went through Harley finally and got a big "get lost". They say it's normal and that they have test bikes with the same noises with 60-70k miles on them. So, WTF I'll ride it til it blows up and build something bigger.
Synthetics like the guy above me suggested do help. I'd suggest Alisyn or Lucas products personally. I tried them all in my race boat and those two held up best.
