Hello all. I'm fixing up a 1986 GS400S (North American; known as the GSX400S to the rest of the world). It's one of these, including the original red/black/white paint: https://www.motorcyclespecs.co.za/model/suzu/suzuki_gs400s 85.htm
The bike sat with a spun bearing for about 15 years, so it needs a full rebuild. I've got it about 75% of the way done, but I've run in to a problem with the ignition coils. The only replacements I've been able to find cost about $200 each, and that seems pretty preposterous. I'm not doing a full resto or anything... just trying to get it back on the road, and I already had to pay some ridiculous prices for all the bearings and such. Some jack-ass ripped the plug leads out of the original coils, so they've gotta be replaced.
The problem is that these coils seem to be a rather unusual combination of parts... they are single-output coils (one coil per spark plug), they have a marked '+' and '-' spade terminal, and they need to be in the 3 to 5 ohm range for the transistorized ignition (at 12 volts). They have an 80mm mounting distance, but I can fab up a mount if I can find something that fits the rest of the spec's.
For reference, the original p/n is: 3341044510, superceded by 3341044X50
Thus far, the only universal coils I've found that have the correct connections have not listed the ohms, and they've had unresponsive sellers.
Does anyone have recommendations for something I could use in place of the OEM coils? Something from a different bike, or a universal coil... I'm not picky - I just wanna get it working.
Ideally, it'd be something available in the US... This bike is apparently very rare in North America, and pretty common in Europe and Asia, but I've had numerous problems with companies being unable to ship products in to the US recently.
Thanks in advance.
