Hi guys, does anyone know which sparkplug to choose? The NGK website suggests NGK Iridium CR8EIX, but someone on this forum suggested a NGK Iridium CR7EIX. ???
Can anyone help me choose? ::)

I just looked it up on the NGK USA website, it says to use a CR8E standard non iridium type plug gaped at .028

I use the Iridium equivalent to the Std plug which was in the machine when supplied Kymco, cant tell you the number as I am not at home to check..still got the box I think , will look later
-
The number represents the heat range you will most likely need . Higher numbers for more aggressive riding . You should probably stick to the manufacturers recommendation , unless you are very aggressive (racing) or very conservative . The person who recommended the lower heat range must think you are a more conservative rider . I really like the iridium plugs myself . Good luck .

Kymco says to use an 8 in my carburated 2007 model. I've replaced it with the iridium 8 and like it just fine. You have the right part number.

Thanks guys, will go for the NGK IRIDIUM CR8EIX.

Has anyone tried changing a plug on a Xciting 500?? ??? ??
It's almost impossible without taking off all the plastic, and even then... :-\
Anyone interested in a brand new iridium plug? :D
-
On My 07 it only takes me about 5 mins to change the plug
-
After the third time, I learned how to squeeze my hand into a claw that fits between the hoses and stuff. Of course, easier to change on a cold engine.
-
Yeah, guile, I tried it through the hatch. No freakin way could I do it. So did it while I had all the plastic off for a valve adjustment. BTW the valve adj was no piece of cake either though I got better after the third attempt! :D
-
I go up from the bottom to pull the wire from the plug and do the rest throught the hatch
-
I would need a child's hand to unplug the sparkplug :'(
It runs fine now.
I hope never happens with the sparkplug in the future because it will be one friggin big operation to change it :(
I understand they solved this engineering flaw with the newer Xciting. Good work.

Once you know where the spark plug is, it's a simple task. Shouldn't remove a spark plug wire by hand, anyway. Rather than a baby's hand, a good spark plug wire removal tool makes it a 10 minute task.
-
There is a special tool under the seat of my Xciting. With one side you can remove the sparkplug itself. Is the other side meant to remove the plastic plug?
-
A spark plug wire removal tool is a specialized pair of pliers with tips designed to go around the spark plug wire boot (plastic), they are available at any auto parts store for $10.00 to $30.00. Careful though, I paid $30.00 for one that wasn't worth a crap, broke first time I tried to use it, took it back. Sorry, don't know brand name but if you have an AutoZone near I got a nice set there for about $15.00.
Edited to add - The tools supplied with any motorbike are barely functional and meant for emergency use. A good 3/8" drive rachet, spark plug socket with insert for holding plug snug, a selection of extensions and at least one swivel joint are essential for making plug changes a simple procedure. A torque wrench is also advised, one of the most common causes of parts falilure is over tightened fasteners.

I'd rather clean the varitor than to replace the sp need somemone to remove and install the sp plug.
Just replaced my sp after 10tkms not bad for the iridium. Replaced it with the same iridium plug.

What mileage/kilometers are you replacing the plug. I see 10K KM thats about 6200 miles. Is that normal for an iridium plug? I thought they should last longer than that.

You should not gap iridium plugs , the fine wire electrodes are easily damaged . The iridium plugs in my car are not even scheduled for change untill 105,000 mi. Chances are you will never need to change them on a scooter .
