I searched the archives to see what spark plug the FJ uses and didn't find anything... so for future reference:
NGK DP8EA-9
Stock number is 5829
Gap is: .035"
And if you don't know how many to order you need more help than I can offer.
I thought the later models recommend the resistor version; DP8REA-9?

Think it depends on who you ask. The NGK part guide online lists one base type as fitting both 1100 + 1200.
What Andy said. At the time I only checked for the 1100 (selfish I know...), but looking here:
http://www.yamahapartshouse.com/#/Yamaha/FJ1200AE_-_1993/CYLINDER_HEAD/FJ1200AE_(1993_MOTORCYCLE)/CYLINDER_HEAD_(FJ1200AE_-_1993) (http://www.yamahapartshouse.com/#/Yamaha/FJ1200AE_-_1993/CYLINDER_HEAD/FJ1200AE_(1993_MOTORCYCLE)/CYLINDER_HEAD_(FJ1200AE_-_1993))
and here:
www.ngk.com (http://www.ngk.com)
the '93 1200 calls for the same plug. Same gap too, .035" or .9mm.
Oh?
Like I'm supposed to trust the people who made the motorcycle AND the people who make the spark plugs? These are the very same people who want your motorcycle and spark plugs to wear out quickly so they can sell you new stuff. Are we supposed to blindly follow the herd? Can't you see the conspiracy? :-)
I'm sure Obama's is behind this! Driving up the price of gas and taking the resistors out of our plugs (I'm sure the resistors give us better fuel mileage!).
Geez, some people are so gullible, just because it's on the internet, doesn't mean it's true. :-)
Uh .... I got nothin. Except that I'm sure that at some point in my life I read a post by Jon Cain that said use the resistor plug.
(yeah, I'll blame it on Jon) :-)

I thought the only point to using the resistor version of the plug was that it would cut down on EM or "radio noise" for those of use using wired in (and maybe even NOT wired in?) electronics and intercom speaker amps. I'm fairly certain I didn't make that up and that it came from old knowledge from the yahoo board. That said - I've used both and could never tell a difference.

I have been told "for my dirt bike" to run a r plug so you don't interfere with your own CDI, I would imagine the same applies here. I was having issues with a new bike and called team green and that was one of the things they said to check.

i agree its his fault gas is so expansive :crazy:

I believe there should be a resistor in the circuit, sometimes it's just located in the spark plug boot. so... if you run resistor spark plugs then the boot shouldn't be, and if there's no resistor in the boot, then your plugs should be. :crazy:
Hey Guys,
The FJ CDI ignitions need a resistor. The rule is "any electronics on the bike that utilize a circuit board in any way", require a resistor spark plug. That ensures circuit protection. I have seen a lot of people use non-resistor plugs with ther CDI ignition box( which will work) but within a year or two fry the boards inside the CDI. If you are running a bike with points( a much older bike typically) you can use a non-resistor spark plug, but bikes from the 1980's and on, use a resistor plug or a 5k ohm resistor cover or commonly use both.

Interesting.
So, what is the difference between a TCI and a CDI?
The reason i ask is because my XS1100's use TCI ignition systems and a NGK BP6ES plug, and i think the resistor is in the plug cap, and i thought that the FJ's were TCI's aswell, and the plug is a DPR8EA.
Just a bit confused now, that's all.
I'll just edit.
OK then the FJ1100 and early 12's use a TCI, transistor controlled ignition, and the later 12's use a CDI, which i think stands for computerised digital ignition.
I'm using FJ1100 ignition systems on both my XJR's.
So, what's better, TCI or CDI?

The term CDI has become sort of slang for electronic ignition, but CDI actually stands for Capacitor discharge ignition. Not sure which is better or older though. Regarding resistors in the cap and/or plug, my understanding is that one shouldn't use both resistor caps AND resistor plugs.
