Yes I upgraded the charging system, new stator and the updated regulator. I also changed over to the Dyna ignition and ran the power to the coils through a relay so it would not have to power through the ignition switch. I ended up replacing all the wiring harnesses, fuse box and flashers with new, as well as the switch gear and ignition switch.

I am having the production gauges rebuilt. It nice to know so much is available for these bikes at a reasonable cost.

I did a Suzuki Rotary and it was really hard to find parts.

Here are a couple pictures of my progress. Its crazy how many detail there on a build you want just right. I'm sure it will need quite a bit of sorting when done.

I installed a dyna igniton and found the way the coils mount differs from the stock coils and will require a custom bracket.

Does anyone make these?

Also anyone now how to post pictures right side up. They dont transfer upright.

I'm surprised your coils won't fit the existing brackets. They should. Can you show photos?
I have a couple of Z1B's restored, an '80 KZ1000LTD restored, a 1981 KZ550 restored and a 2008 KLR 650 for off road fun. My wife has a 2019 Suzuki DR 650 for on and off road.

Before posting, open the pictures in something like MS Paint - rotate to proper orientation and save over top the original - that'll fix the orientation issue. If you use a more advanced photo editing app, it's liable to maintain the goofy orientation even after saving.

I know this oh to well. I have touched, cleaned, Vblasted, plated, re-chromed, polished, painted or powder coated every nut, bolt, washer, and bracket if it was salvageable. Bought NOS when possible, if not the best of the aftermarket. Soaked rubber in brake fluid to restore. Investigated part numbers, serial number, and dates. Laced rims, rebuilt wiring, degreased, and regreased. I have built a bike (well not completely yet) from the frame out. Call me crazy but I’m loving it. Can’t wait to see it finished and gleaming in the warm summer sun.

Good luck, I hope yours turns out exactly the way you want it.

Here’s a fresh order of NOS from Partzilla just arrived today!

Mikaw, I'd be interested to hear how your soaked rubber bits hold up. According to this video, they will eventually sweat and start firming up again.

What is the benefit of Dyna ignition? I mean, they are not cheap, so why over stock of its working properly?

Thx and sorry for my ignorance

I too am surprised they won't fit. I am restoring a (1982) GPZ 7500 & replace stock with Dyna & had no issues.

Pros and Cons. But I feel the pros win.

Pro-Is pretty much set it and forget it.
Con-Some will say points typically won’t fail instantaneously as a electronic module will so with the Dyna S you could be stuck on the road. True it could happen but I personally haven’t heard of any such events.
Con- Cost outlay
Pro-Over the life how many sets of points will you replace

Then there is all the stuff I really don’t understand completely, dwell timing which helps coil saturation, no change in dwell like in points as they start to wear.

Loudvhx is the electronic ignition expert. He can fill in the rest.
