If it's anything like my 650 you slacken everything from the clutch lever down then start adjusting from the right side of the motor.
Hold the centre nut with a size 10 open ender and the centre screw with a decent bladed screw driver.
Slacken the nut then wind the screw in until it just touches the actuating plate, then back it off a fraction and then tighten the lock nut again while still holding the screw in place with the screw driver.
That's the actual clutch adjusted, then take the slack out of the cable using the lower cable adjuster, then move up to the handle bars and see if the lever needs slack or adjustment.
That is the basics of clutch adjustment, of course it won't work if you left something like the actuating plate out (don't ask, I don't like to talk about it!)
