I've noticed that when I start my 1100 cold, there's a 'woo-woo' noise for a second after it starts. After it warms up it doesn't do it but it has to be fully warmed up. It sounds like it's coming from the starter and I'm thinking this might be a warning sign that my starter clutch is going away. It has 30,000 miles and has been doing this for maybe 8000 or 10,000 miles. I never give it any throttle when starting and it always fires right up, but who know what the POs might have done. Any thoughts?
