Installing a Dyna-S on a CB550
Last week I removed the points plate from the advance assembly but didn’t unhook it from the wiring harness. The procedure is fairly easy and a matter of simply pulling the blue and yellow wires from the harness.
Here is a pic of my old points plate removed from the wiring harness. It’s still works and I’m going to keep it just in case things don’t work out with the Dyna-S.
Since I was down there pulling wire, I decided to replace the right side engine case bolts that held the points plate wire in place. The bolts were frozen and pretty chewed up but the metal tabs that held the wire in place were still good.
Brand spankin new Dyna-S.
After removing the spark advance assembly, I had to remove the points cam by twisting to the the right and pulling.
Next, I had to slip on the black magnet cylinder thingy. In order for it to sit perfectly in the advance assembly the spring mechanisms must be pulled out so the black magnet cylinder slides down and engages with the notches
I lined up the number “1″ with points 1-4 on the advance assembly.
Slide the Dyna rotor over it and bolt down with some shiny new stainless steel allen head bolts.
Then I slid out the rubber grommet from the old points wire.
Split it with a razor blade.
Placed it on the Dyna-S cable and in the slot in the engine case.
Ran the the cable through new stainless steel allen bolts.
White wire goes into the blue, black goes into the yellow. The red wire is spliced into the 12v brake light wire. I’ll post more pics of the splicing next weekend. The next post will cover static timing the Dyna.
