I have 120 miles on my 09 RK. I just had the 1000 mile service at the dealer. It cost $340. I the future I will be doing service myself. I have the manual, tools, mechanical/electrical experience, and I bought the J&S jack so I can get this old body under it. Plus, Glider has placed some great tips and links to videos so you can see what to do.
I figured it this way. The guys at the dealer seem pretty well trained and see a lot of Harleys. This is my first Harley and it seems easier to service than most other bikes.
By taking it to the dealer on the first shot, I think it will be more difficult for them to deny future warrantee claims I may have. Plus, if they checked everything on their check list which they supplied me after the service, there's stuff on there I might have missed.
I will be keeping all of my future service records showing purchased oils etc. I created a log in Excel that I will update as I do the service. I have a notebook that has everything in it from day one including "baby pics" I took as the dealer was un-crating my baby.
But, this thing runs so well, and it looks like they are making a quality product so it could run forever if it's serviced properly.
