Would remove splicers and re-test resistance in secondary winding by measuring ohms with meter probes touching wire cores at ends of stubs from coil.

Then refit just one splicer and re-test.

Then re-fit the other splicer, and re-test.

This testing should show whether one of the splicers is affecting resistance through the secondary wiring.

Left Coil
Primary 1.9 ohms
Secondary (at splice) 15,100 ohms

Right Coil
Primary 1.7 ohms
Secondary (at splice) 15,800 ohms

Now my question is.....why am I not getting anything past the splicer? These are new wires.

These readings look okay, because the coils seem very comparable to each other.

Could be mistaken, but thinking it's okay to use the splicer for connecting solid-core wire (from coil) to new resistor-style wire. Am seeing nothing to indicate otherwise in NGK's website where the splicer is described.

However, it's of course necessary that the splicers be correctly installed. But I don't know how much of an issue that might pose. Or whether there are any fitment instructions available..

Should all measure the same resistance, with or without the splicers, or with only one splicer.

I am getting around 15,000 ohms at the end of the splicer. But when I put the wires on and test the end cap I am getting really high readings like (Left: 74,000) and (Right: 24,000) It makes no sense. Shouldn't the readings be around 5,000. And why would the readings go up instead of down?

Because there is something wrong with the connection of the splice. Take the splices off and read the resistance through each splice by itself. Red on one end of it and black on the other end. This will verify the splice itself isn't introducing the resistance. If it is zero, which it should be, then the problem is in how the wires are being connected to the splice.

Repeat the above test but substitute the plug wires for the splices. If they read zero ohms then its the connection.

More resistance results in higher ohms. Less resistance results in lower ohms.

Measuring between the splicers shows resistance in the secondary winding inside the coil. And should be the same as measuring the resistance between the cores in the stub ends without the splicers.

Measuring between the caps adds the resistance offered by the resistor plug wires.

24,000Ω on the right is probably okay.
But 74,000Ω on the left seems way too high (perhaps due to faulty connection through the splicer).

For comparison, the stock Z1, with solid core (non-resistor) plug wires and resistor caps, is supposed to measure about 30,000Ω when measured cap to cap, which would include resistance in the secondary winding plus resistance in the stock resistor caps.
Measuring between the plug wire leads, without the resistor caps, would be less resistance.

I took the new wires off multiple times and re-installed and same thing or nothing. Finally took them off and tested the new wire it self and those things are junk. You have to hit it just right to get a reading. I finally got them back on and am getting 23,500 ohms out the left coil and 24,000 out of the right coil. These suppression wires def. add more resistance. If I had to do over I would definitely buy solid core wires with resistor caps. What a PITA!

I hope those numbers will work. I guess I will find out tomorrow if that is why one of my cylinders wasn't firing all the time.

Well that didn't help the issue any. Still not getting proper firing in #4. I am waiting on my tools to do a valve adjustment if needed. How come I can take the plug wire off of the #4 plug and sit it on there and it fires better than when it is securely on the plug.

Pardon my ignorance:It's been a while dealing with carbs.... But I also noticed when I had the bike running when you revved the bike up you could see mist come out the back of #4 carb. is that normal or is that the sign of a mis-adjusted valve blowing pressure back out.

Resistance isn't mandatory in the wires, caps or plugs.

If resistance is desired (to reduce electrical interference in radio reception or a sensitive electronic component) , only one form of resistance should be utilized, either wires or caps or plugs.

For example, where resistance is desired, the non-resistant Dyna solid core plug wires (with their integrated non-resistor caps) could be used, along with a resistor spark plug such as NGKBR8ES.

Two indications that the cylinder is running to rich, probably because the float level is to high.

As resistance increases, current flow decreases while voltage increases.
When you pull the plug cap and just lay it on top the plug the resistance goes up, along with the voltage, which causes a hotter spark, enough to clear the fuel fouled plug and ignite the rich mixture.

The fuel blowing back out of the carb is because the cylinder is not firing.

Ok thanks again guys.

I guess I will check the fuel/float levels again and see if they are still good.

I had to go double check my spark plugs and make sure they weren't resistor plugs. Nope NGK B8ES.

In all honesty I hope it is the fuel/float height causing this, but that would have been the last thing I would have thought since I checked the levels recently.

Here is a video of what is going on. Let me know what you think!
