Not worth a toss now. I have kept up dealer stamped service histories and they dont add jack shit to the bike value. In fact, I would contend you are better spending your wedge on a skilled independant rather than the 16 yr old gibbon that most KTM dealers will let loose on your bike.
Oil and filter changes I do myself so I know exactly what is being done. Anything else is done at Tagg Racing. I would rather burn the bike and claim on insurance than let the local KTM dealer touch it.
