Hey automag - nothing about buying that bike was stupid! I say that because I recently did the same thing. Except yours is much nicer and newer, I bought a 2000 Sherco 2.9. Also with surprisingly low hours. Just a few easy tweeks and it's running great! And it's honestly the most fun I have ever had on a dirt bike. And that's saying a lot because I always have fun when I ride. But this is a whole new level. Now my KTM 200 gets much less ride time. If you're like me though just be careful when you get back on the KTM. You'll be trying to hit the same obstacles that you have learned to clean on your trials bike which will make for very amusing viewing for any bystanders!
Also, one of the best things I did was to join this forum and make use of the search function, and read lots of posts.
And the other best thing was to take the advice of the members here to become a customer of rypusa.com. Ryan has the parts needed, ships quickly, and is an amazing resource. And I would highly recommend that you buy his Trials Training DVD's. They are both incredible, though the second one features techniques that are still way beyond my skill level. I have worked my way through the first DVD and it has made a huge difference in my riding.
