I did it on a 1200 Bandit (don't ask....)
I just removed the 'dogbone' links, cut the required ammount with the grinder & welded back together - worked a treat. No reason it couldn't work on anything else.
(Although they may need lengthening instead, guess it depends how the linkage is set up.)
It must be a good weld as they are under a lot of stress
