Replacement Coil Help Please?

[Guest]

I just need to know what coils to get for my 1978 GS 550. I downloaded a copy of the service manual from BikeCliff's Website but I cannot find the proper ohm rating for the coils I need for this model. Any help would be greatly appreciated!

They need to be 3 ohms.

Thanks very much! Any suggestion who I should buy them from? I was thinking Dynatek.
And what is the advantage of replacing the ignition (point and condensers) with something like a Dynatek S or similar product?

Nearly every UJM of the day using points and condensers utilised the same coils, more or less; so you could tap up a knowledgeable bike breaker and get easy replacements quite cheaply if you just want to keep your old points system going. For the old system, around 4 ohms is about right. Later electronic systems were a bit fussier and generally like the ohmage to be around 3 - but no less - unless they specify that, perhaps for high output.
If you want to buy new, Dyna are as good as any and probably better than most of the stuff you see on ebay, which has fairly uncertain origins or quality control. Going electronic on your ignition is a no-brainer - better starting, better gas mileage, slightly more power, better all around.
The only advantage with points is the ability to fix them at the side of the road with some baling wire and twine, but otoh, the electronic system wouldn't have broken down and stranded you there in the first place.

Great! Thank you!! So is this what I need? And does it seem like a decent price?

Well, given that's including their coils, I think it's about right. atvgalaxy would have been my preferred supplier of Dyna kit, but the shipping tipped it out of reasonable reach, so I made my own.
