Right on the handle bar, where the cable comes out of the lever, there is a knurled tube and lock ring just like every other motorcycle ever made. Loosen the lock ring and Screw In the knurled tube, (the little part that is sort of the end of the cable). It is easier to move the knurled part if you pull the clutch lever and then try to move the knurled part as you let the lever out, (takes a little of the tension off the cable sheath). Don't turn it much, cause it is not likely to be off by much.
When you pull the cable the first time, even before you try to adjust the cable look down on the left front of the engine. Find what moves when you pull the lever. Follow the cable down to the place where it is attached to the engine. Look at the lever like arm that attachs the cable to the engine. Watch it move. Is it hitting on anything or binding since your tip over? Is it bent? If it is, that needs to be bent, carefully back out.
Good luck and Bon Chance with the marriage and all that stuff.
