So- I just picked up a 1975 R90S and the centerstand can only be deployed by hand- the little arm thing that you step on to drop the stand is broken off right at the left centerstand arm. I guess my options are: (a) buy/find a new/used centerstand. (b) weld a new arm onto the existing stand. (c) find out if there is some sort of aftermarket bolt on type thing that would restore it's function. The arm thing that is missing (at least on my old /6) was flimsy at best and sort of grew to become this ugly, twisted piece of metal- there has to be something better... What do you guys do when that piece twists or breaks?
