Broke a spark plug cap...

[sodakproud]

I broke the plastic cap on one of my spark plug wires trying to get the broke off spark plug head out of it... ie my question http://www.xs11.com/forum/showthread...ark+plug+wires So I was wondering if NGK makes some cables with the caps on em? All I got was the wire from my ****ty moto shop 100 miles away. I just want a simple solution to this. Any ideas? Heres a pic.

I just want a simple solution to this.

Just order one of these and it screws right on the existing wire, like yours does. Tape your old one up or slip a piece of heater hose over your broken cap so you can ride till your new cap shows up.

What's left of your cap UNSCREWS from wire. You'll see how that works/makes connection once unscrewed. If end of wire is corroded, side cutters and cut off a 1/4 inch back and screw a new one on. Beat me to it, but what Bikerphil said will get U going again.

the plug caps came in ngk boxes the numbers are short cap "LBO5FP"(8030) and long cap "XBO5FP"(8435)

The new NGK caps also come in different resitance values. 0, 1K and 5K.

The XS uses the 5K Ohm ones, unless you want to run resistor plugs instead.

So, I just bought some BP6ES plugs and plan on installing them when I rejet and tune my carbs. Untill I then, I plan on putting new plug caps on my wires and want to make sure I get the right ones. Are the 5K resistor caps are the correct ones for my '79F, anyone confirm this? Im going to continue searching... Thanks.

Do you have a source for the 0 ohm caps? I've looked all over any can't find a source any more.

[WMarshy]

No real source persay, I called the local auto parts store and asked if they had NGK screw on plug caps, he said yes but he only has the 90 deg style. Mine uses the short caps on 1 and 4 and the longer 90 deg caps for 2 and 3... I just was wondering what are the "best" caps to use, more resistance or less since Im using non-R plugs...does it make a difference?

If it does and he dont have the correct ones, ie length or resistance, I will just order them online and wait for them b/c it runs fine right now. Its just and excuse to get out and ride but ultimately I think the spark could be stronger, plugs are a little sooty even on the lean side...

Canadian Tire carries all three, here.

I would check Napa,or any motorcycle or quad shop. They are still in use on many recreational vehicles.

[WMarshy]

I already have multiple sources, I just want to figure out what resistance I should buy! Im ready to walk out the door and if he has multiple choices of resistance I want to know whats best. Your earlier post say 5K... what is your source, OEM manual or is that just what you decided to use..? Does it make a difference???

[rpgoerlich]

With the plug cap removed from the wire, measure it's resistance with an ohm meter. Typically they are 5kohm and running non resistor plugs.

[Crazcnuk]

Stock they are 5k ohm. still trying to find out how I know that...

These days it's getting hard to get non-resistor plugs, so it might be easier to go with 0k ohm caps and just use standard resistor type plugs.

What I am not sure about is how MUCH resistance spark plugs have...

[WMarshy]

Thanks, it sounds like the 5K caps are the most common/easiest to find so that may be the reason why you used them. I just didnt want to get the wrong ones and find out the hard way that they do something bad to my coils. I didnt end up buying any b/c he didnt have the long 90 deg caps, just the short ones. Non-R plugs are still easy to come buy here...

[Crazcnuk]

Anywhere I have seen them they have had all 3 (5K, 1K and 0 Ohm) so it wasn't a convenience issue.

These bikes call for the 5k Ohm, we've had this discussion a few times over the years.
