Finishing Up

Now just reinstall the gas tank, and reconnect the battery. That's all there is to it.

There is very little that can go wrong with this installation. However, if upon starting your bike the engine sounds funny, rough, or stalls, turn it off immediately. Then check the following:

  • Did you remember to screw on, and tighten the little sparkplug top nipples for every sparkplug, if applicable for your type plug wires? See Parts List section above.
  • Are the sparkplug wires fully seated on the sparkplugs? If you used too much dielectric grease they might have unseated.
  • Are the sparkplug wires fully seated into the coil nipples? If you used too much dielectric grease they might have unseated.
  • Have you accidentally bent any of the sparkplug wire terminal-ends? If so, they may not be making good contact. Use a pair of needle-nose pliers to carefully bend the terminals back.
  • Have you somehow gotten any of the little input-wires--two for each coil--disconnected or poorly seated?
  • Have you accidentally broken or damaged any of the little input-wires or connectors?
  • Have you securely tightened the brass screws for each of the input-wire posts?
  • Have you somehow gotten any of the little input-wires mixed up? The coil for the rear cylinder (the left one, if you're following the normal, stock configuration) should have the wire-pair that includes a yellow wire. The coil for the front cylinder (the right one, if you're following the normal, stock configuration) should have the wire-pair that includes a white wire. Note: It doesn’t matter if the input-wires for each coil are reversed, as long as they are attached to the correct coil.
  • Are both sparkplug wires for the rear cylinder attached to the left coil?
  • Are both sparkplug wires for the front cylinder attached to the right-side coil?

If all the above checks out, but the engine still does not run smoothly, reinstall your stock coils and start the bike again. If the bike still does not run smoothly, you have likely damaged the connection within one or more of the little input-wire connectors. You must carefully check each one.

Start the bike again. If the bike runs smoothly with the stock coils, but not with the new ones (and all your connections are good), one or both of your new coils, or your sparkplug wires, may be defective. Contact your supplier.

Once everything is running well, you can relax, knowing your ignition system is running much more reliably.

 

Ride on.

Hi, 
 
Thanks for the great articles. 
As a guy doesn't really wrench, Randy's articles, as well as all the articles on the forum are great! 
 
For the Nemesis coils, the article is qualifying the resistance parameters for 99~03 models. Anyone know the resisitance parameters for 04 and after? 
Quote: 
Our coils are rated at 1.53 ~ 2.07 ohm resistance, (99 to 03's)
