On the 750 twin, the wires are molded into the coil. Yours are probably the same. Z1 sells a 4 Ohm OEM coil (EMGO brand) for about $36 so it's smarter just to buy the whole thing than fool with trying to dig the wires out and replace them. Don't know if a four Ohm coil fits yours, it would probably run OK.bloglos wrote: Spring is here and I'm getting my KZ650 C2 ready for summer. New plugs, oil change, brake pads, etc. I noticed that my plug wires were in baaad shape. I figured I'd pick up a set of new wires and install them this weekend. I have my bike in my dad's garage until next weekend so I don't have it in front of me to check, but I've read that if I have the stock coils, then the plug wires might be attached to the coils? Is this true?

I can't tell from the picture, but can you replace the spark plug wire on those coils? It would suck to run into the same problem after replacing coils.

I don't know if the mounting hoes are the same, you need to check. The wires are also molded in. But if you look at the price of the splicers and new wire, it isn't much more to get the whole thing. I personally think old coils should get pitched, they don't age well (guess how I found out).bloglos wrote: I believe that the stock coil is 4.3OHM so I'm thinking that should work. So I guess as long as the spacing is correct I should be able to use that setup. Please correct me if I'm wrong!

Does anyone have experience with with either of these? I'm not sure what the difference is.

I've also heard that even though I'm running points, I can still use the Dyna 3 OHm Green Coil, which would be great if I decide to switch to an electronic ignition in the future. Would I be pushing this coil too hard?
Thanks for all the help guys. It's appreciated.

"bloglos" post=443227]I'll probably replace the coils as well just to be sure. They aren't too expensive. I'm just having some difficulties deciding on a coil.

I believe they are the same coil, but the latter comes with straight plug caps, and the first has none. You would just purchase the prefered caps seperately.

Yes, you can use the 3ohm Green Dynas. The coils present the load to the ignition, so if the coil ohms are too low, you would burn out the ignition, if the coil ohms were very high, the coils would produce a weaker spark.
Best o luck!

They have different bolt spacing, the top link is 4" and the bottom is 3.5". There is also one similar to the bottom link with angled plug caps;

edit: sorry misread the description, they are all 3.5" bolt spacing.
