As I did for my GT/GS750 project , I installed the Boyer Bransden electronic ignition system on this rebuild which I bought from Walridge Motors
who are the Canadian distributors. Other systems are available, some of
which are probably better suited for racing and high performance, but
for this bike and the sort of riding it will get I think that the Boyer
Bransden system is more than good enough.
Below to the left is
a photo of how I've spliced it into the wiring harness - this photo is
actually of the GT750 install, but the wiring is exactly the same on
the GT550. The control box is mounted under the top frame tube. To the
right is a photo of the pickups and the mounting plate as installed on
the GT550. So far at least I am really happy with the setup -
both bikes start easily and run smoothly.
