Something went wrong on the way back (\uff1b\u2200\uff1b)
That’s right.

Looking quickly, #3 is running cool
The #3 plug is nicely burnt…
That can’t be right.

Swapped #2 and #3 caps
\u2192Symptoms unchanged
Hmm?
When I swapped #3 and #4 plugs
\u2192#4 is running cool
#1 is running cool
It’s the plugs…

Misfire = wet image
This kind of thing happens.
Learning every day.

Dual-pole plugs specified for transition-period bikes
I’ve had a bad impression of this plug since way back
Basically I don’t use it for conversions.

Even with oil cooling, from JR8B (single-pole) to JR8C (dual-pole)
I change those to single-pole.
For some reason
“Single-pole seems resistant to problems”
Even if it fouls, you can somehow manage
and get home. That kind of plug.

By the way, with iridium, once it fouls
it basically won’t recover, so I don’t use it. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n
\n

I’d like to use it if I could choose, but only “C” M10 settings available. Hoping for future options <\/p>\n<\/span><\/span><\/span><\/div><\/div><\/div><\/div>\n\n\n

\"\"<\/figure>\n\n\n\n

At first glance it looks like iridium, but
the outer electrode is “D-shaped”
That seems to be the key point.

Resistant to fouling and high durability
Should be a plug you can safely use even on carb bikes <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n

Hmm? Looking at the NGK site, it’s not listed as compatible? <\/a><\/p>\n<\/span><\/span><\/span><\/div><\/div><\/div><\/div>\n\n\n

Iridium is compatible but DX is not
This is consideration for using CR8EK (dual-pole)

Basically the same shape, so no problem.

Actually surprisingly tedious.
Getting the right length and layout is difficult

If you’re going to put in the effort
“Don’t use the stock length and layout” <\/strong>

New cord is hard to insert, so I drill a pilot hole. <\/p>\n<\/span><\/span><\/span><\/div><\/div><\/div><\/div>\n\n\n


Since the cord is soft
to avoid putting undue stress on it
if you don’t make a pilot hole
it surprisingly doesn’t screw in all the way. <\/p>\n\n\n\n

Measuring the cap side to be screwed in
“Two points: the tip of the screw and the back”

For example
“20MM to the tip of the screw”
“30MM to the back, let’s say.”
You need to screw in at least 20MM.
If you don’t look at the numbers
it becomes vague. <\/p>\n\n\n\n
