There are several threads here regarding solutions to getting an ST on the main stand. I built a 2-step ramp totaling 1/2" to ease the process at home.
In the field, getting a 'run on it' lets the bikes momentum do the work. I would never start cutting and welding the OEM pieces.
I did not do the cutting and welding myself, but I
had thought of this mod before I saw the ad in 'For Sale'. I am reasonably sure that I would have arrived at the same conclusion after a few more failures to get the bike up on the cs in my garage and would have done the same thing. This guy bought a used stand (my guess ebay from a wrecked bike) and made the mod. His brother is a welder and he did a fine job. I bought it, as said before, had it powder coated, and during winter layup stripped the bike and swapped the stands. While the bike was still on the dolly (huge slab of wood on casters) I tried it. I could not believe how easy the additional 2 or 3" of leverage made this task. I put the bike up on the center stand and took it down two or three times. I sat on the bike to see what the interference with the cs foot pedal and my heel would be - minimal. I was prepared to swap the stands back to OEM if there were any problems. So, this worked wonderfully for me and was a keeper! Were I to do this over, I might not extend the foot lever as far as this guy did.
I tend to agree with your point to this extent - I would really hesitate to cut and weld on an OEM piece of hardware if I did not have a stock replacement on hand.
