For anyone who has a 7H plug, many scooters come with the NGKcr7Hsa. Go to Amazon and type in your scooter name/ performance plug, you will see 2 plugs only 1 comes. It is a replacement for the factory plug, for much better outcome. Its a BRISK plug, I called them to make sure it was a match, type in brisk usa texas ,and ask IF unsure. The plug that comes is an upgrade from the pics. ENJOY~!

So youre talking about motor scooter engine spark plugs, is that right ?

Oh goodness, don't get him ....oh, never mind....
A very nice little spark plug for the KYMCO LIKE200i is the Iridium plug made by Denso , or NGK.
I preferred the color of the NGK to the Denso after a few 100 miles. But that just might be my engine.
Email to NGK says to use same heat range as the standard plug.
Because, some say Iridium plug is hotter, therefore go to one range cooler.
Not so NGK spokesman says. NGK took all things into consideration when marketing the Iridium plug - use the same plug heat range - just added the "X".

What is the advantage of an iridium plug over standard Stig, especially if they are the same heat range.

I run the NGK iridium. Love the plug.
-
in my case using an iridium plug noticed that started better idled nicer and lasted forever without gapping it. its a great cheep and easy upgrade!

So Stig, my 125 LIKE takes a CR7HSA and the iridium equivalents that I could find are the Denso IUF22 and the NGK CR7HIX. If I read your post right, the NGK because it has the X will not be hotter than the standard plug and what benefits should it do.
Cheers, Paul

Just recently changed the NGK CR7HIX plug in my Agility City 125 after 40000km. I put it in at when the scoot had a bit under 5000km, changed at 45000km.
The ground electrode was eaten up, widening the gap, it still worked, but compared to a new plug that I put in you could feel the new spark was stronger.

Dang it, going to get one and try it. :)

You cant go wrong with an iridium Paul. They do seem to make my Kymco run smoother and being an iridium plug, they will last for a loooong time.
-
Thanks, appreciated.
-
Yep....nothing magic or spectacular - but noticeably smoothed the idle and made for a more secure sounding tick-over while sitting at a stop light, surrounded by Detroit Metal.
Plus - since I get nervous about over-tightening these tiny plugs - it is nice to install one and forget about it for a good while.
Both are made in JAPAN.

BTW, when you put in the new plug, do not over-tighten it and use some anti-seize on the threads. The previous owner of my People had stripped out the head and I had to repair with a helicoil insert. I am not planning on ever taking out the Iridium plug unless the performance drops.

Going to fit it tomorrow or Sunday. Went for a ride tonight and the same old problem happened again. Idle was low and when you go to take off it splutters before revving so hopefully the new plug will help. I can check the connections as well.

Hope so....there are bad plugs out there...but darn few it seems.
Still think you need a dealer to adjust the carb..
Good luck

New iridium plug fitted and does feel better, really glad I did it. Here is a picture of the old plug after 600 kms;

The simple answer is that they last longer. If you poke around a bit you'll find that's the one thing that folks agree on.
Of course that means the smoother idle etc. from a newer plug will last longer as well, but if you're the type who frequently replaces your plug anyway the main benefit will be to the manufacturer's bottom line.
There are some who'll say that it has a better spark, but actually it's very slightly the other way. Of course there's another myth regarding the spark strength there since once a spark plug has sparked, unless it's extremely weak, the fuel/air has ignited so that's that. With a fresh plug there is effectively no difference.
So...I run Iridium in my Burgman which is a true PITA to get at the plugs. I run copper in my Kymco since it doesn't get the miles that the burger does so the longevity of the plug is somewhat moot since it's about an extra two minutes to check, & gap or replace the copper when checking the valves.
I ain't gonna put up links to back this since I did my digging long ago (there are even youtube hits to back this if ya dig a little), but also cuz plugs are like religion. You're really not going to get many converts even with the extra efforts. If you're really interested poke around and you'll find it.
Cheers, & flame on.

You must be talking about the big Burgman?
I think it is pretty easy to change the plug on my 400 Burgman.....one of the few things easy on the scooter.

I agree Paul....and the plug I removed was a new NGK ...so the improved idle was due to the new NGK Iridium plug i replaced it with. Seems to make a nice difference on these small scooter engines and electrical systems.

No worries Stig. How does the replaced plug look to you, does it look like it was running rich, lean or looks ok.
Paul
-
imo its ok but a little rich. thats why when cold with a slight gas it stalls. id give sole litlle more to the air screw... 1/8 to a 4th of turn and see if you get better results.

Got nothing re. carb tuning.
Haven't had one since 1975.
sorry.
Nice picture though. :)

No worries Stig, thanks anyway.

Replacement caps just screw into coil wire.

Yup a 650. One of the plugs isn't too bad but the other is a true PITA.
