Spark Plugs & Wire Caps

[gtem]

NGK sold off their plug cap business a few years ago, I ended up buying some NOS stuff on ebay and it was about double in price from what it used to run new. I'm almost wondering whether K&S maybe bought NGK's plug cap stuff and has now restarted production under their own brand now?

I use this type. No resistor. If you make it yourself you know it's quality. Ton's is the vendor for parts.

Here are parts from eBay to do the job. You could use your stock coils if you solder the high tension wire to about 1/2" of clean wire sticking out of your coil. The bad parts of old wires are obviously the ends that screw into the caps which get corroded and can be cut back slightly until you see clean wire but the real culprit is cracked insulation which you sometimes can't see with your eyes. All you need is about a 1/2" of clean wire sticking out of the coil. Make sure the repair is wrapped with insulation and heat shrink for a professional repair. The cutting into the coil stuff is unnecessary. I did this type repair (actually many old bikes) to a CB550 about 25 years ago and he brought it in last year for leaky top end gaskets and to this day the wires are still like new. However, the 3 ohm Dyna coils with no ballast resistor is the way to go for top performance on an XS11.

If you put a thin smear of dielectric grease on the caps, they will slide on easily, and it keeps water out. This is something I use on all my soft spark plug caps and boots. Some car makers also require you do this so you can remove the boot after 50K miles without destroying it.

Agree, but don't go overboard with that grease. It is not conducive and if you smear too much of that and it actually gets on your electrical connections it can cause problems. DAMHIK.

cajun, like ALL things, moderation! I usually just smear a thin film on the lip of the boot, and it makes it easier to remove a few years later on things like the riding lawn mower/snow plow I have.

I love that LT1000. I have a green one. Mine would smoke a little on start and I traced it to the head gasket. There was a breech right here. It's a common problem with lawn tractor motors.
