good idea except WD-40 is often misused as a lubricant when it s not.Simple tip that will save you a lot of hassle. The clutch cable spring (the smaller one, not the heat shield), just toss it and install without the cable. Will save you plenty of hassle. Also, use some WD40 on the cable innards.
Another tip, get a double brake lever and connect both front and back brakes to it. That way you engage both brakes with the same lever, leaving more real estate on the other end of the handlebar.

It's main purposes is to remove moisturize and unfortunately will break down and remove what little grease a better use would be CLP lubricant on the cables WD-40 breaks down what little film may be on the cables from the factory eventually causing the cables to rust
