Manual sais JR9Cs, they 21.75$ ea (x4)
NGK site says D8EA, 7.37$ ea (x4)
DR8eaix iridiums available.. advantage? price on par with the 9Cs?

cannae read what's on the ones what's in, not at home with tools to pull one =S :brickwall:

bullet points please people, any advantage to iridiums? is the magneto system going to fuck out if i put the 8EAs in?

D8EA's would be pretty standard for an 80's 4 cylinder, if that's what the NGK site recommends can't see what the problem would be. Have you checked the number codes to see what the difference is?

$7.37 is too expensive, just bought a set for my old bike for $5.50 each, they're ripping you off dude.

NGK JR9C

NGK DR8ES-L

jah. just put me glassies on and looks like ends in A. so i'm guessing it's the D8s in there atm.

... difference? codes? whut now? i'm guessing 8 is hotter, but the 9Cs have lower resistance? don't know, don't know how to check either? linky?

where is 5.5$ ones?! (i'm not TOO miffed about the 8$...)

JR9Cs are dual electrode....supposedly longer life...
so. pay 88$ for a set that MIGHT last XXXXXKM or 30$ for a set that will probably last XXXXKM....

Not such a bright spark after all huh?
I bought a set of D8ea's for my XJ600 a couple of months ago from Supercheap in Whangarei. Cost $5.50 each.

i don't think there's anything wrong with the brightness of the spark,:motu: just a matter of "i havent done it since i got the bike and i'm fairly sure the last owner was less than careful"
ie, routine maintenance.
will check out supercheap. cheers.

Interesting thread. I had just looked at the price of plugs for my 1200.

Have you looked in the Lodge catalogue? *snigger*

I think the issue will be not brightness of spark ... but more a dud plug or two.

Supercheap would be appropriate for him ...

cool. don't really get how it applies though. (i know how it SHOULD)

if my manual reccomends Js and there are Bs in there... the thread in the head is fucked... yargh! will swap with a noo set of what's in there :s

[Akzle]

wait :facepalm: D not B. :confused:

JR9C=12mm, resistor type (i was right), 9, low angle ground electrode
D8EA= 12mm, 8, 19mm reach, special design...
altho i'm fair sure the Ds are a 5/8 hex.. cos my 13/16 wasn't into it, from memory. :scratch:

might just shell out for the fancy ones, see how they do. give the fuken thing a birthday.
needle/jet sets anyone?
