When I repaired my stand, I welded to increase the width of the stand contact point, from about 5mm to 8mm.
This assists in slowing the wear of the stand contact point.
The weld is built up towards the inside of the stand.
By placing the bike up on 3" blocks of wood, the c/stand can be easily installed and removed to grind the contact points equally.
The finished grind should have the stand at an angle which is getting close to.....well, falling forward off the stand, but not too close!
My stand is an excellent bmw ride off stand now, fantastic when fully loaded for touring.
