'81 GS550T ignition replica for a few euro !

all the information about the igniter replication is free to everyone
The program that i made the PCB is Sprint-Layout

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,
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.

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

Awesome! Looks like it works just like it should

Well done again Kokar, that is excellent work!

The test was completed and the results are shown in video

Final test --> http://www.youtube.com/watch?v=itB0bQ4DzSY

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

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

last update before the final test

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.

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...

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!

R18,R28 = 300 ohm
R19,R29 = 470 ohm
R17, R27 = 300 ohm 2W
C01 = 100nF/63v
C02 = 100μF / 63V/105°
C11, C21 = 22nF/63V

Excellent work Kokar!

Do you have a schematic and a parts list yet at all?

Very glad it's working on the test bench, when do you plan on a ride test?

Hi,

Very nice! Your workmanship looks excellent! Thanks for sharing.


Thank you for your indulgence,
