NGK CR7E plugs

[Stig / Major Tom]

My main gripe about the Iridium spark plug is that....on a rainy old day - with wet flurries expected - and you're wanting to do something good  to your scooter  - you'll feel pretty dumb if you change your Iridium  plug.*
Dumb things'll probably last till the Rapture.

* and WHY do you even have a second Iridium plug? You'll be too old to remember where you put it- before you'll  ever need it!

No worries  mate......I  joke around too much. (the "you" was me)
Yes, good plug.
They're not magic - but, for the $, a good addition to a scooter.

Thing with an Iridium plug vs a standard plug. I feel that the only advantage is the convenience of it for having a long service life. I am not too concerned of an additional 1hp on the butt-dyno.

Assuming it has a 50000km service life and that it won't have a failour is those 5yrs, perhaps then it would be worth it, but I rather a fresh plug every 15000km.

Some real strange owners replace an Iridium about that often....I've  heard.
Get bonus of Iridium plus fun of tinkering with scoot!

I have replaced a NEW standard spark plug with a  NEW iridium plug. I could not tell the difference. I am certain though that if I replaced an OLD standard plug with a new iridium, there would be an increase in performance. I believe many people do this and assign the performance increase to the plug type, not the plug condition. I would like to hear if someone else has done an apples to apples comparison and get their feedback. Personally I like to change plugs a little more often just to see if the engine is burning correctly but there is nothing wrong with the iridium's.

Seldom will changing the plug make a huge difference in flat out performance . That would require bumping  the displacement, and/or changing the factory programming, changing the final delivery gearing, slider weights and such. What I did notice was faster start up, when cold, and a more consistent idle, plus the iridium plug will last longer the any other type of plug.

Way back when my LIKE200i had just a few miles on it I replaced the plug with an Iridium. Did the same on the Burgman and the Piaggio when they were new. The only reason I did not make the change on the Forza was because there was no Iridium version.
In each case I noted a smoother idle going from new to new.
By far it is the least expensive, easiest, mod to three scooter engines (and two Scions) - with noticeable + change in my limited experience.
Plus...threading in these tiny plugs in alloy engines always makes me a little nervous. So, the less often I have to do it ,the better I like it.

If I notice no other performance improvements  -  $10 once every few years to obtain a nice, more stable idle, while sitting in heavy traffic on my scooter is, to me....$ well spent.

My cheap tachometer did pick up the change in idle rpms, and rpm steadiness - when replacing the new NGK with new Iridium NGK in my new LIKE200i engine. Also, my new Burgman never died at a light again after making the change. True, not an unknown, and a temporary issue for new Burgman engines - but I only let it happen once before parking the Burg till I bought the Iridium plug.
