    Upload it to Youtube then you can link to it here. You can't actually upload videos here. They have to be hosted elsewhere.

    I got to play around with a gy6 ignition on my sr500 today. I took an old lawnmower tank over, filled it up with gas and after a little tinkering got it to flow to the mikuni, which then drained it through the overflow. Hmm. I used a spray bottle to also shoot some gas into the carb directly. I hooked up the gy6 ignition to the low speed pulser. After a few kicks the bike fired and ran for about a dozen revolutions, then died. After a few more starts I repeated the process with the high speed pulser. Similar results. The gy6 ignition works! Unfortunately, the carburetor wasn't carbureting so I couldn't keep it running long enough to check the timing but I have a feeling it will be in the ballpark. It just about has to be. I pulled the carb off, turned it over and a mysterious green fluid ran out. Definitely not what I had been trying to use. Obviously I'll need to clean the carb. It may be a few days, maybe weeks before I get everything back together but I'll post more results then.

    Been Reading and watching the videos
    My impression is that the machines are firing to much advanced at idle
    I have had no Firing mark on my rotor because of a substandard rewind so I have moved around the firing listening and checking the Throttle response are you calling it " Blipping "
    Here
    A bit Rough running -- Kick back -Need for choke
    Some has a fluctuating firing Position ..can it be the wrong data in to the Box --Voltage or
    Pickup data
    Has not seen anyone talking about the GN250 stock pickup which i suppose would be giving the correct Physics for the box

    Have read a bit about the Controller ... Not sure if I have the right manual
    But there can be protection bits so modification or readout is not Possible
    Without complete erase och the flash memory
    " Lock bit protection Modes " Appears to be the term

    Mines running about 18-19° at idle. It starts easily and has a nice smooth idle. What's wrong with that?
    Good luck finding one that's affordable...

    Less than a C-note for a crank fired E-Ignition doesn't break the bank. If the OEM pickup gives the correct signal it's a win. I understand you want this as inexpensive as possible but a few extra bucks to make it simple could be money well spent.

    Unless I misunderstand what you're saying, find out the stock number of degrees from the center of the magnet to the timing mark, and file in a timing mark there on the edge of the rotor. Measure the circumference and multiply that by degrees / 360 to just measure to the spot with a tape measure

    I don't disagree Greg. Here's our problem. There's precious little room for a sensor. The one we've found (@Team Junk found) just barely fits. I'm not willin' to spring that kinda money just to find out it won't fit. Anyone want to buy that one (or find another) and donate it to the cause? :whistle:

    I've been happy with my Boyers. I do like the idea of an economical crank fired ignition. I may join the fray this winter. What's another project when the snow is flying. Since the bars and gambling machines are shut down I'll have extra money to play with. :unsure:

    I can see it is a lot of money for a stock pickup and the grand total needs to be kept down .Otherwise one can buy a Manufactured Ignition .
    But once the proposition is out there Perhaps someone knows something.
    I am thinking that the Gonzo box manufacturer has done job in that direction. Perhaps Some Chinese bike out there has a pickup for that box.
    .
    Regarding idle advance there was a gentlemans videos with a stock TCI running much smoother than the later installed Gonzo box.
    At least there in that case appeared to be a problem of importance.
    Assuming yours is running perfect Jim .I would like to see some more videos of Smooth idling bikes and a " Normal " Throttle Response . From that idle. The lesser advance at full advance perhaps is OK.
    And I do believe it is of common interest .. As well as input for development

    When a warm-ish non-rainy day comes along, I'll try and get a video.

    Just in case anyone wants to try one, you can get these for $17 for two on eBay. They test out at 150 ohms.

    Sort of. I see now he's not selling them in pairs. Here's a link to the same pickup from the same seller.
    https://www.ebay.com/itm/192119441987

    He has these though. They have two leads instead of one. I haven't tested these but should be about the same.

    You can get them from China too; GY6 pickup coils.

    says it's for a Honda. You're saying that's the same as the GN250 pickup?

    All I know is it's 150 ohms and its a trigger coil. Its cheap enough to try if you want to.

    Kinda looks like a guy could cheez off the bracket, bore a hole in the stator frame, push it into place.
