I need to replace my coils, was removing them and noticed one of them was split open along its entire length. What are my upgrade options? The bike was not running when I got it, the previous owner said it was misfiring on the left cylinder, I think I found why.

Don,



When you say "work well for the price" what do you mean? They are cheap. Do they "perform cheap"? I'm looking to replace the coils on my 78 CX500, but want something reliable, and am willing to pay a little more for that.



Looking to marry new coils with a new Ignitech unit.

What I mean is they are half the size of the stock coils and I have never had a problem with them.



I'm using the ignitech also and it's nice having new parts compared to the bulky 30 year old parts that you don't know when will fail.



I did notice on the right coil it must of got a bit of heat to the underside rear of the casing because it melted a bit but not in any part that would hurt function.



The only bad thing about them is the 2 week wait for them to come from china.

A pair of these will work,

Just have a slight different mounting bracket.





Or take a gamble on a pair of these because they are so cheap,

My only concern is the length of the HT(Thick wire).The actual coils will work.Or contact the seller and check the length of the present ones.If the above cheap ones are long enough then they are a mega bargain.Most sellers will combine postage.

I saved the seller on my ebay so I could find them easily. They did run out of them for a while but it wasn't long before they got them back in.

Not if you have the TAI(Transistor Advanced Ignition) e.g the two Sparker modules.The CDI coils only work on CDI versions of the bikes/engines.



For the TAI engines you can use Standard car coils if you can find them.The CDI coils have only 1 LT(Low Tension/Thin wire) and 1 HT(Spark plug wire) the Standard Car coils/Transistor coils have two LT wires(Two thin wires) and the main HT/Spark plug wire.





It's this type,

But that's expensive so if you have an old car scrapyard/boneyard around you might be able to get a couple cheap off some old cars.



They do come up on Ebay as well.

I've been reading the forums about getting replacement coils for 1979 CX500 Custom. One of the coils has a crack running the length of it and one of the spark plug caps is chipped. I found some NGK caps and now I'll looking for coils that will replace my old ones. I read this post http://cx500forum.com/forum/technical-help-forum/1807-spark-coil-replacement-options-2.html and ended up buying these coils: Ignition Coil ATV Moped Go Kart 150 200 250cc Dirt Bike Chinese Sunl Roketa | eBay.

I successfully installed the coils today, but now my bike is running really rough. The bike will start, but as soon as I put it into gear it dies. I think it's flooding because the spark plugs aren't getting enough spark. I'm wondering if the cheap spark plug wires that came with the coils can't deliver enough spark (they're flimsy like rubber and flop all over the place). I know I can buy some 7mm bulk cable at a local parts store, but I'm nervous ripping out the new spark plug wires in case they are permanently attached I end up destroying the new coils. Lots of worries and not a lot of answers.

Wondering if you have any ideas. Thanks in advance.

I have a 1978 honda cx500 and was looking into replacing the coil packs.
I have a couple of questions, which hopefully don't get too many eye rolls.

Are the plug ends universal? What I mean is, can I basically buy any reasonable coil pack and adapt it to my bike? I realize I may need to fabricate a bracket or splice the hot wires, but other than that am I correct?
I was looking at this one:
Ignition Coil Module Motor Parts for 500cc 600cc Honda XR500R XR600R Dirt Bikes | eBay
I trust in the opinions of the experts on this forum, buy was thinking I might get something rated for the displacement of the bike.
Thanks in advance for your input.

The cheap coils work great. I got pair from ebay for $16 total. PW50 or some such thing. You just swap in your current plug caps.
