valve
Take the black cover off and check the exhaust valve spring for rust. My 07' 600 IQ did the same thing. spring was so rusty it fell apart when I opened it. Also check your exhaust bellows, rust can rub a small hole and leak eventually. I painted my new springs with hi temp paint. have 3000 miles on new springs. they also have new bellow material now to they are light blue instead of orange. maybe 09's already have these tho. good luck.
