Yes, the two 6 tab nuts are what angus means. If you look at the nuts you will see they are slighty curved. Put the first nut on with the curve up, the second with the curve down. This locks the two together.
I use Harley's fall away method of adjustment.
With the bike up on the center stand, use a jack to lift the front wheel just of the ground. With the wheel satraight ahead hang a weight of the rear tip og the front fender, hang it so the weight is just off the ground. Put a mark under the weight. Now put a mark one inch to each side of the first mark. Now with just a light slow push on the end of one hand grip, move the wheel until it tips over off center on it's own. This is fall away.
While doing this watch the weight. As the wheel falls away the weight should be over one of the marks.
If the fall away is before the weight is over the inch away mark, then the bearings are to loose. If the fall away is after the mark the bearings are too tight.
Adjust the bearings untill the weight is over the inch away mark when it falls away.
