I'm coming up on 600 miles soon and contemplating the same issue as well. For many years I have done all the servicing on my Guzzi's, so handing my bike over to a dealer's workshop seems strange to me. However, I think it prudent to respect the warranty, at least for the first few service intervals. I would like to watch how they do the valve adjustment, just to see how they actually access the valve train. Drop the motor out of the chassis? Take off the shroud, tank, radiator? Whatever, I just want to learn the procedure so I can do it myself. But since mine is the first 390 Duke my dealer has ever sold, likely they don't have a clue themselves about how to work on it (which makes it all the more important to keep an eye on them!)
EasyRider, I agree with you that 600 miles is a very short interval for a valve adjustment. However, a brand new engine, just running in, is a special case. There is a lot of metal-to-metal honing going on, which could affect valve clearances. Also, heat cycle loosening of the cylinder head bolts can increase valve clearances as well (re-torquing the head bolts is part of the 600 mile check). I understand your concerns about a long round trip to the dealer for this service. I would say the initial 600 mile service is the one NOT to skip - try to watch what they do and then skip the subsequent service intervals if you can do the service yourself. This of course will void your warranty, but for you to judge whether it's worth it. I plan to let the dealer do the first 2-3 services, then if the bike seems tight and reliable, I will take over this task myself and let the warranty go.
