i'm on a 550k1, but my bike came with the ignition moved up top. Just broke(wires disconnected from the switch) and I wasted a lot of time before someone told my why the wires on my replacement were so short.
Basically just cut the wires in half, solder in some longer pieces and rewrap. I've got a the rusty little scrap of metal that had mine setup up top if you're interested. Could probably be sanded and cleaned up.
