Yeh mate, same problem down under, imagine how brittle the needles were on mine after 30 odd years in the aussie sun, they crumbled to dust when touched, I bit the bullet and got new needles from the German site, he got them made up when I asked if he had any, took a few months, that's the z1300.de site, sorry to say they are 27 euros each, and have a special way of replacing them, but they are new, orange and black, and work well, he sends instructions on how to refit the new ones correctly, cheers
P.S. I did try some aftermarket replacement type, trouble is the hole for the pin was too big, another was too short a needle, they have to be just right and balanced to suit the application and to read right
