Kdude,
I attended that class and made my own index. I was unaware of the wiki version. Regardless, here's my index. If I can figure out how to add to the wiki page, I'll do that tmw.
The class was excellent and the videos are priceless. I went because my dealer was floundering and I was afraid they'd fail. They did. I'll do my own first service in a couple months. I indexed the vids so I could find what I needed.
Best
Miguel
