It took me ages to find this upper mount point for the centre stand spring, despite reading anything I could find. I just didn't realise quote how far up the upper eyelet was going to be and that there really is no easy way of seeing it. It doesn't help that my bike is filthy, it's not been looked after particularly well in it's life until I got it, now slowly putting that right.
Anything that can get in the way of you seeing the upper eyelet for the spring, does. It wasn't until I took off the silencers and pulled the drain pipes out of the way, and then lay on the floor and looked up that I could see what I needed to see, but on my first attempt I didn't see what I was after, so I went back indoors sulking wondering how on earth I was going to get the thing fitted!
In my case it worked best with the short reach of the spring being hooked ot the upper eyelet, with the long reach stretching down to meet its mount point on the stand. Hooking the spring through from the inside outwards. Otherwise I found the coils of the spring fouling the barrel you put the bolt through to keep the stand on.

I had to engineer a suitable 2mm spacer too (you can just see it on the outside of the left lug) to stop lateral movement of the stand once it was mounted. And the rubbers are essential, one on the straight bar of the stand under the bike, the other on the leg that sticks out, otherwise you'll have a very noisy installation as you hit the bumps.
