My K75s centre stand needed a bit of refurbishment. The feet where they contact the ground had gotten pretty thin especially on the leading edge. Matt kindly lent me a spare stand that he had making the job a lot easier. I ended up welding a strip of 5x20x60 flat bar onto the feet. I built up the sides and trailing edge with more weld and then blended it in using a 100mm angle grinder with a grinding wheel. I finished off the blending with a 100mm flap disc followed by a pneumatic burr grinder fitted with a flap wheel. I sprayed on some spray filler and a light sand then followed up with a couple of coats of satin black. Once dry I filled it with some LPS3 and sloshed it around  then fitted some new rubber end plugs. These required a bit of grinding down in order to get them to fit and even with the grinding down they had to be pounded in with a nylon hammer. The end result looks good and has the added benefit that the end plugs don't contact the ground on deployment. The slight increase in height hasn't made any noticeable differences to deployment. 
Regards Martin.

I did essentially the same repair as well Martin.  I used a chunk of pipe that had the same internal diameter as the external diameter of the tubing that BMW used to make stand, split it in half, and then welded it on.  The bottom of my stand had worn through on both sides and so I had to build some of the existing walls up a little as well.  I'm quite thankful that I never went out to parking lot to my the bike in a final but undesirable state of rest.

What happens if the rubber plugs leak or are missing is that water enters the stand and it rusts. It would be heaps worse in countries that salt their roads. I used to regularly every I-2 years fill my stand with LPS 3 which is a rustproof coating. Rust wasn't a problem with mine it was just worn away from 26 years of use. 
Regards Martin.
