Own a snowmobile or a river boat.. go out and drive the pants off them. They WILL break numerous times out in the field forcing you to not only mechanic on them right there but also when you tow it or limp it back home. My wife asks me litteraly every time I come back from snowmobiling, "Well, what did you break this time?" Sad part is, she is right. It is a rare ride when I don't break something, but that is what happens when you ride high performance equipment to the edge.
Of course, I can't afford to pay anyone to wrench. If I had to do that, I wouldn't own the toys. But if it makes you feel any better I would be nervous about diving into the heads or cam of this bike having never done it... not that it would stop me from trying, I would just post a big-ol HELP ME I SCREWED UP on this board and wait for the guys to come to the calling, which I know they would. It's a great board.
At least you aren't wrenching on the windy side of a mountain at 10 degrees in the dark, 20 miles from your truck... been there, done that.
