So I am also replacing my spark plugs and I have searched and read almost every thread about spark plugs on this page. I orders ca-cycle works plugs which are non resistor and are backed by Chris Kelly. When I recieved the plugs I noticed they where the same plugs I use in my 1978 rd400 2stroke. Now my ignition system I have on my 2 stroke have to use non resistor plugs because of the type of coils I have on thereor I will damage them. Will I run into problems with my 09 696 with non resistor plugs. I am not looking for performance out of them. I don't really buy the ho gains that are said to be given with the non resistor plugs. So what do you guys think ?
come on guys help me out. resistor or non resistor. I have till tommorro and I am just going stock. lol I need to start this bike. I miss the noise
if you ordered from ca-cycle you are good to go . . .
I wouldn't use a non-resistor plug. I did a quick search and the recommended plug is NGK DCPR8E
Using a non resistor plug on a street bike is not a good idea. It can cause interference (ignition static) on radios,and TVs as you pass by, and possibly affect your bike's ECU.

weird, since I was unable to get the recommended plug and was able to find teh non resistor model, I did install it in my M620 and have had no issues . . . ???
You may have a resistor built in the spark plug cap.

I have the Evoluzione spark plug cables .. .

It can also make your electronic flasher for LED directionals go batshit ;D

I said can, not will. Depends on how well the computer and wiring from some sensors are shielded.

howie, we all know how "weird" my particular bike is . . . .

+1 it will cause interfence and with time ecu problem's. And there is no resistor in the 620 sparkplug cap.

but, they're going out, being in the engine for one year and about 5000kms of local gas so time's out on them . . .in go Champion R4CH, I know you all prfer NGK, but, these work better, at least here
You should be running

I've used both . . . somehow my Gina likes the Champions better ???
I have read some threads that suggest the iridium plugs need a larger gap even though the manufacturers say not to gap them. Folks who had problems with the iridium plugs have set them to factory gaps and even larger say it makes them work better... ?? Just have to be careful and not break off the electrode.

Here is that thread. http://www.ducatimonsterforum.org/index.php?topic=54367.0 (http://www.ducatimonsterforum.org/index.php?topic=54367.0)
Gaps from NGK
NGK 4339 DCPR8E Gap: .028" (0.7mm)
NGK 6546 DCPR8EIX Gap: .032" (0.8mm)
So they are gapped larger. :)
and another (down at the bottom of the article)

I have read this several times in several places. .04 maybe? I have not had any problems with the stock gap but after 5 years on the same set of plugs I might try something different with the next set.
thanks for all the reply's. I am going to go with the dpcr8e plug and going to use the ones I bought from cacycle for my 2stroke. all works out. lol
