Congratulations! You now have a gorgeous piece of art and masterpiece of technical engineering. With a little TLC, you shouldn't have any problems. Break in is pretty easy. Keep the front wheel down until you hit 800 miles, and don't go passed the 11,5 redline! Make sure she warms up to at least 140 degrees before you ride. Watch out for the radiator reservoir. It WILL crack. Mine went out around 4k miles. My husband's at 5k and my friend Steve's at 2K. It's under warranty, so you shouldn't run into any hassles. Put a set of carbon pipes on her if you can, that way your friends will know that a Duc is coming down the road!
Man, congrats on your purchase. Sorry I can't help you with the service cost. 4-valvers cost more than my econo-Duc. But, there are lots of great people on this form who can shed some light on this topic... Enjoy and be safe.
I hope that after I die, people will say of me: "That guy sure owed me a lot of money."
