I was trying to impart a notion of simplicity to the problem. I guess it didn't work.

The point is that adjusting valves is easy and if you read the link I posted above, you literally now know how to adjust valves. I'm not saying don't spend your money getting your maintenance done. I am saying that you could buy a Wevo shifter and have change left over for the price of two valve adjustments.
