Hi Dave
I had the same problem with my MK 5 - it got heavier as I got older ! I bought a Honda CBR 600 side stand complete with bracket and spring -for a few pounds off ebay. I made a triangular plate of 3/16 inch sfeel with holes drilled to pick up on the footrest bolt and the rear suspension pivot. I mounted the plate then offered up the side stand and bracket to get the right angle of dangle, marked the plate, dismantled and welded the bracket on to the plate. It worked out very successfully and have since made another one for a friend's MK 5 using a Honda CBR 600 side stand again off ebay. Attaxhed are some photos.
Regards
Paul
