Where do people relocate the coils to after they either replace with eBay units, or put a skinny tunneled tank on the bike?



Any help is appreciated, '78 Cx500 with the fatty tank on it..



I'm a little frustrated with my bike today. spent a little over two hours on it, and got nothing done but the straight pipes painted... And found a random miss on the left cyl...



And one more thing, these are the correct coils to buy right?

You want these coils.

Relocating without using using the stock position can be a pain.



I cut 1/2 way through the bracket on the coils themselves. One to the front and one to the rear so I could bolt them together. The coil brackets must have 20 individual flat pieces that make up the area to bolt to. Then I bolted them to a thin piece of metal and bolted that to the right side coil/engine bracket. I thought I had a picture but I guess it ran away.



The newer coils also have longer wires so it's possible to put them farther away.

I purchased these:

since they only have a single mounting bolt I attached them to the rear engine hanger brackets( one on each bracket). There is a hole already drilled out in the brackets in which they fill well. I added a lock washer so they wouldn't wiggle loose. I've put a little over 100 miles on with them so far and no issues.

Interesting. So which of the two wires did you hook up?

Good point. I kinda thought about that too, so I've been checking them to touch after each ride. So far so good, but that's not a definitive test. If those symptoms occur in the future I'll swap them out with a spare pair I bought a the same time. I think I payed $4 when I bought them a few months ago.

I'm horrid at fabricating things.



My uncle loves making brackets, and is pretty much forced to as he runs an HVAC business.



So my method was to show up at his house, rip off the old coils, and tell him I need to make the new ones work. I came over with some sheet metal, so I wouldn't have to use his stuff. He told me to throw it out, and he went into his huge scrap yard, and came out with some perfectly bent metal.



He ground off a bit of a tapered end so the coil could sit in it, but couldn't rotate. Then drilled in the holes. He also found some wires that were color coded to my ignitech, and hooked them up to the coils. Also, of course, two bolts and lock nuts are required for this to work so you can bolt the coils to your new brackets.



Here are the results.

Thanks Blindstitch, I'll try a set of those. I am gonna try to mount them under the seat area so I can run the BSA tank I managed to get my hands on. but I gotta get the coils here and make then work before I go choppin and cuttin on stuff. as far as relocatin then, my welder and cutoff wheel will make a spot..

Did you use the cables off of your old coils? If so, was it a straight plug and play or did you have to modify them?


The coils came with the spark plug wires if that's what you're asking. The caps that are on the wires of course don't work with the CX, but they screw off just like the CX caps do.



The wires that go to your CDI box will have to be purchased separately though, unless you want to chop the wires off of your coils which I don't recommend. Once you cut them off, it's going to be tons of hassle to get the wires back on, and you may later learn that the coils weren't even bad! Just get some wire that looks about the same size (sorry, not good with electronics) and find a female blade connector and crimp it to the end that goes to the coil. Then I believe you need a male bullet connector on the other end to go to your CDI or Ignitech or whatever you have.



I just realized that I didn't have my wires hooked up when taking the pics, but you can see the male wire connector on each coil.

I picked up a pair of these, got 2 different models, similar in appearance, but not the same. may not be a problem, but still bothered me enough that I just ordered another set hoping to get a matched pair, will hang on to the others as spares.
