Currently no. I am just placing a spade under the battery screw and using bullet connectors as my switch for testing purposes only. I eliminated any unnecessary resistance and devices. When wired up correctly the main power switch is on the load side of the 20A fuse

I will ground the gonzo separately direct to battery. This was considered in my troubleshooting at one point but i ruled it out as the components had no issue before with this exact wiring. The schematic I should have been more clear with wire crossover depictions. The power supply is run to the...

Drawn off memory at work.....I think this is accurate.

The gonzo triggering is original. I am using the orange feedback wire from pickup coil. I have the gonzo grounded directly to clean frame and the battery directly to clean frame at different points. For testing, the coil supply is directly from battery positive with 5a fuse and only connected to...

I hooked up another new coil on separate power supply directly from battery with a 5A inline fuse. Different spark plugs. The bike fired flawlessly right outta the gate with no reg/rec plugged in. I shut the bike down (wish i ran it longer without the chargin system inline). I then hooked up a...

Everyone's input is appreciated. I will wire up the ignitor and coil separate from other noise. My new coil is in route. For initial testing I will leave the charging system out of the equation. IF she likes the new setup and doesn't spit the coil, i will plug the charging system in and get readings

The latest coil out da box was bout 4.7 ohm on the primary. Bad box was my initial thought when the second coil shit. I bought another new GN ignitor and coil and boom third coil cooked. The strangest part is that the first coil lasted for several test rides and suddenly shit...however looking...

SO far she has eaten 2 oem coils and 1 CHI-na coil for various jap bikes and "Replaces Fit For Yamaha part number : 1AA-82310-09-00 / 36Y-82320-60-00". All three coils failed leaving the only common item left is plugs and wiring...

I will try an inline fuse....I have had the failures with new caps and oem caps

I checked the new caps resistance....they are about 1050 ohms. The plugs i have not checked. I will get another coil, non resistor caps and plugs to try.

Haven’t felt one to be hot. I am running new resistor NGK caps and BR7ES plugs

When she runs shes very smooth and strong. Periods of run time are a few mins max. I am running new BR7ES plugs. I have gone over the box positions and connections numerous times and matches what you have posted. Paths to ground are .4-.6 ohm

Yup. It fires with a different coil and then cooks It. The last two failures had open secondary paths. The first bad coil lost all continuity on primary and secondary

What would cause this pile to eat up coils? I am running the GN250 igniter and have since eaten 2 original 1980 coils and now a modern replacement. I have scoured the entire system and found nothing out of place. I am very intimate with it since i spent all winter troubleshooting. Each failure...

That is a good point, I guess i will see once i plug the new reg/rec in. The issue occurs at range i would consider peak charging RPMs. My new CHI-na parts should be here late this week. My previous thoughts on it occurring at peak charging was the the rectifier was cooked along with a bad diode...

I have found the smoking gun.....Interesting road of troubleshooting. I spent the last full week tearing down carbs, adjusting fuel delivery and tuning carbs with no change to the mid range sputter. At one point, I decided to check ignition with my timing light. It was at that point I saw the...

First start up of my bike with the GN250 box. The weather has finally allowed for a road test. All is well except for a mid range bog/sputter. Top and bottom range of RPM is great. I am suspecting the issue is fuel related but I have not found the smoking gun yet. I will update if anything changes.

The rear hub. Just by looking at my disc assembly and online drum hubs, its appears that with a spacer between the disc armature and the bearings with provide enough space to clear the housing or perhaps no spacer, I am just spit balling. Here is a picture from ebay of a drum hub, i drew the...

I do not have a drum brake hub in front of me to measure or compare. Is it possible to use a drum brake hub without the brake shoe assembly on the hub, with a disc brake setup?

I have time to spare and if the offer still stands to repair the stock tci box, I may just take you up on this. I have another engine missing some stuff and would like to have a working stock box around.
