OT - on the cold starts.. ( Im in FL so its never that cold..but.. heh ) the first 30 secs to 1 min... its louder.. sounds more open throat-ed.. then it quiets down.. not a rev note.. but a open throat-ed one..

can any one explain why that is? At first I imagined it was just the time to get the oil circulating.. but it almost seems like a valve is open of some sort.. then closes?

I love that open throat-ed sound! I can only imagine what its like with LTH, HFC's, and F. I. CBE!
