I also have the CFM and I installed mine myself. I don't usually and the only thing that caught me up was that I had to adjust my cables after I was done to get it to go into all the gears. I have daily'd it for almost four years now and I love it.
There are two kinds of people: those who say to God, "Thy will be done," and those to whom God says, "All right, then, have it your way."
C. S. Lewis
