'81 GS550T ignition replica for a few euro !

I LOVE IT! I already changed mine to a Dyna but I'm still amazed by this! One question about the red and green lights, were they for something in particular? Thanks!

Excellent, My igniter went bad right after I bought my bike, like on the ride home, and the ebay replacement is definitely used. Next time it pop's I'll make my own.
Unless you plan on putting together some more of these for sale?
I'm estimating this is the same as the one for the 450, although I haven't bothered to look...

Excellent Kokar, fantastic work!

Apopleptic (and others) this is the same ignitor as used on all the '80 - '82 450's, the '80 and '81 250T's (I think that's right), and the same era 550's with mechanical advance I believe.

last update before the final test

That's very neat packaging too Kokar, and I like how you've given it a nice thick base for a heatsink too, good idea!

Looking forward to the final test

[kokar]

The test was completed and the results are shown in video

the next step is to put resin and install in my bike...

[pete]

Awesome! Looks like it works just like it should

Well done again Kokar, that is excellent work!

[kokar]

Pete, i think now is right time for the Rectifier - regulator to be to replicated .....

Kokar,
Fantastic! Excellent work! I am putting the details in my archives for future use if you do not mind.
I would appreciate it if you would give us the schematic and PCB files in the format (I think it looks like you used Eagle?) you designed them in.

Could you add those monitoring LED's to the schematic as well?

I am very impressed and thank you for sharing.

Thanks a million! Thankfully I have Sprint layout and Splan. Could you supply us with copies of the .lay and the .spl files you used?

Have you road tested the ignitor yet?

Thanks again and excellent work!

[kokar]

I haven't tested it in real life because i must put the resin first to prevent the humidity to destroy the PCB

i have only the .lay file
you can download the .LAY file from the following link

Attention !!!

if you will try to make the igniter you must isolate the power transistor from the heatsink like the following pic...
