Someone else in this forum, in the relatively recent past posted lovely photos of the stainless steel strap they welded over the "stops" end of their stand.
I have to say that their method was/is much neater than my approach of simply building up the ends with weld.
I am going to do the fix with stainless steel strap to my wife's bike in the very near future. She has been grizzling for years about how hard it is to get on and off the centre stand. We bought her a new stand (and side stand) which let me tell you is an interesting process for a 1979 model, to BMW's credit they didn't have a side stand in stock and they issued orders to the foundry that originally made them to knock them up 6, one for my wife and 5 to put into stock.
Sorry, digressed. SHE complained that the new stand only partially fixed the problem, but I ignored her as at the time I could not see any way to improve the situation.
I now realize that in fact it is the frame stops on her early model frame that have worn down in the past 35 years. The frame is too bloody hard to get at and I am unsure if the stops are cast iron or forged steel - using the wrong rod could cause a world of hurt, so I am going to use strap to build up the stand as that I know is bright mild and will not be harmed by welding to it.
