Some if your clutch adjusting nuts look sunk beneath the top of the cup? You want to aim for the top of the screw head being in line with the base of the flat, screwing in further will apply more pressure and weight to the lever.

I agree with Allen and the way I usually adjust the springs is to screw them in until the springs are coil bound and then back off the adjusters a couple of turns so that when the handlebar clutch lever pulled in and Kickstarter used, the clutch spins freely. You might need to screw the adjusters in or out accordingly but the idea is to get max spring pressure and minimum drag. It's probably best to err on the side of a bit too much much free play as in the real world these clutches can drag a bit when cold.
