But... (and it's a big but) loosening the axle, pinch bolt, etc has NO effect on fork alignment on a fork of this design. There, I said it. This whole 'bouncing thing' is from the days of 'conventional' forks with twin pinch bolts on each fork bottom, (such as an FJR or Honda ST1300) not upside-down forks with the type of axle that the FJ has. Look at the axle closely; it's a shouldered bolt with an integral nut that has no option of position -it's either tight or it's not. It's so idiot proof, even I can do it.
You can leave it loose, bounce the front end, but as soon as you tighten the axle, the fork tubes are going to move (or not) to their 'installed' position -there's nothing you can do to change that. The single pinch bolt on the right leg is merely a safety-pin to keep the axle from turning out "just in case".
If it makes you feel better to bounce the front end with all the bolts and the axle loose, by all means, enjoy. But your efforts will be for naught as soon as you tighten the axle.
So then how do we align the forks/bars?
Mine are still a bit off despite my efforts to align them.
