I've fixed the self-retracting function (I consider it a design fault by safety zealots) of my side stand yesterday by simply sawing off the protruding pin at the end of the bolt that holds the stand.
I'ts really simple :
-remove the springs from the stand using a shoelace throuhg the end of the springs and wrapped around your hand.
-remove the bolt from the stand and put it in a vice by the smooth end.
-saw or grind through the bolt at the start of the smooth part, so you get a normal bolt with the thread at the end.
-try if it fits nicely through the stand without protruding too much, clean the start of the thread wit a file if necessary.
-apply some grease and put everything back, again using a strong shoelace or cord to put the springs into place.
Now the springs will travel all the way forward with the stand, beyond the point where their effect is reversed and they're keeping the stand forward, just like all sidestands used to work before our nannies took over this world...
Be aware that this modification could be unwise for extremely absent-minded people : you've traded the chance that somebody knocks your bike over by simply touching it for the chance that you forget to move the stand upwards before driving away, which will become very obvious in the first lefthand turn you make :-)
