Withot going back through the whole thread..........
Are you using the original 80-83 TCI pickup or did you's get the Suzi one to adapt

Stock TCI pickup (on the idle pickup) now advanced a degree or 2
Mines running with the TCI pickup. Since I like riding it and plan on regular (
) reports on that setup, I'm planning on setting up a spare motor as a test stand to work out the other pickup for earlier bikes.

this diagram has the low speed pickup misidentified. Pls see updated posts
Yamaha wiring color codes
Installation Notes and Status 06/01/20
1980 -1981 TCI Engines
Make and install pigtail to plug box into OEM TCI spot on the harness. Check Timing. Go ride and see what you think.
982-1983 TCI Engines
These engines have a 8 pin connector instead of the 6 pin of the early tci.
Any photos of the 8 pin connectors appreciated.

Replacement for the TCI igniter box
The Gonzo TCI
How To
The Darkside
Converting non TCI bikes
Coils
Any coil hooked up to gonzo must be at least 3 ohms and dual output.
Do not try to hook the 70-79 points coils together on the coil input on Gonzo!!
Gonzo should work fine with the stock 80-83 TCI wires and coil. If you are retaining the stock coils and wires all you need is the TCI pigtail and the GN250 box

Honda CB-200 -450 Ignition Coil
{there a bunch of Hondas with these coils. Used OEM are a good bet. Repops have been fine so far.
GN250 CDI {it's not really a CDI)
70-79 non TCI Conversion
Working on it. it is a thing.
Stock Pickup vs RX pickup RX pickup
The following is Jim's research on magnet placement.
So I rested the ruler against it and lined one end up on the timing mark.
And here's where the other end wound up....
Drew a line with an ultra fine sharpie....
.... and drew a line from the edge back to the center.
Sonofagun... it splits the magnet right down the middle. So I duplicated that process on an old style rotor without the magnet.
Added some tape the the sides and ran the marks down the sides of the rotors.
Also did the same on the timing mark side of the rotors. Then I stacked 'em on each other and lined up the timing marks. Used a mirror so I could get a pic of both sides at once....

First drafts. I would of never guessed it would be this easy.
I have no knowledge on how these things work........
The question for me about having copper surrounding the magnet on the TCI rotors is.........I remember a member here who swapped a points model to a TCI ignition and if my memory serves me correctly he mounted a magnet into a Points model rotor.........that wouldn't have had the copper surrounding the magnet, i quess the question is, is that copper necessary???
By the way i have been following, just not contributing as i don't have any idea what your saying..........Great job and it looks like for, (in Aus), about $100 a points ignition could be converted over to Electronic.
Would any of these work as a pickup/pulser coil for this.

The pickup we are experimenting with is used on some smaller Yamaha singles. It costs less than $10.00 (231.00 CAD for Pete) on Ebay. I think the GN250 was popular in Oceania so the boxes should be common there. They also seem plentyful on english amazon.
Not in Aus they don't..........yuo joke about it being $231 Canadian well double Petes $231and add on 50% and your getting close to prices over here........new aftermarket is thin on the ground here............if none of those in the link would work would this one from a RE 500 ????

...with circles and arrows and a paragraph on the back-a each one explainin’ what each one is?
The following diagram shows the high rpm pick connected to Gonzo???
Is this correct or has the text box hidden part of the circuit?

Looks like it will work from a physical stand point. The mounting tabs look like they could be bent 90 degrees to mount to the stator cover.
Gone back and looked. I think I may have the pin functions on the TCI connectors juxtaposed. The white/red in the upper left corner of the connector is probably the idle pickup. The white/red on 650 harness to gonzo pickup+ is how Jim is wired.
Working on a pre TCI conversion pdf. Doing fact checking.

I can tell you this much: It should be plenty durable with everything potted in epoxy like that.
At least the solder joints won't flex as much.
Trying to get to town to HF to get something for the rotary tool to cut plastic box off.
The English final little jab at the Japanese bike invasion. "English" (Indian) RE part to keep the 650 running.
Just did some browsing around on the Australian Amazon and Ebay sites.
On amazon I looked at a lot of the Chinese stuff that is all over Amazon in Texas and the UK that all comes from the US through Amazon. Wow
Ebay was more of the same with the pieces mailed from China and the US.

Jim, gotta say that your striking the line to find the placement for the magnet beat me by a mile. Great job.
