ive always had a side stand on my aerox but it somtimes falls over in the wind so 2day i went to put a center stand on that came with a load of spares i bought a while back. anyway i went to put it on and found the pivot of the old stand left in the hole and visably cut with a haxel. so i tried belting it out with a lump hammer and a punch then i tried the same after ridding the bike for 15minutes still it wont budge. anyone got any other ideas how i could get it off?
