I don't know how many LT riders do their own maintenance, but I do my own. My '02 has close to 80 thou on the odo and I have done all the service work. Except for Major failures.
I believe the secret is to do maintenance on your own bike. The reasons are simply:
*First, you learn about your ride, which may be helpful in South Dakota...
*2nd, I ONLY use tools I carry to work on the bike (On some jobs, yes I add more tools)
*3rd, BMW bikes have a TON of issues, you need to carry enough tools or enough money to deal with THAT FACT.
*Being able to fix the 'simply' things can really empower a rider.
Use a good manual, use the tools, use this site, practice knowing your bike!
We ride thousands of miles on 2 wheels. People wonder why? Its the freedom!!
If you can't get along without routine dealer support, you should not be riding extra long distances!
Just my $ .02...YMMV
