Iridium plug for Strada Eurojet RX150i

[smoothie]

Dawg,

What gap are you using on your 150i? I changed to the Iridium NGK CR7HIX and am running a .024 gap setting. I think this might be slightly on the tight side for this scooter. I would assume the gap setting would remain the same regardless of the plug type, as long as you are running the standard electronics?

When you get an opportunity, can you post the 150i owner's manual? Mine has come up missing. The one I received must have been one of the early ones packed last Fall. Much of the information pertained to 2 stroke models and even confused the mechanic I had check everything over.

I was under the impression that you shouldn't meddle with the gap on iridium plugs... I read that somewhere but can't remember exactly where it was. Someone please correct me if I'm wrong!

You are correct. You are not supposed to touch the gap on them. I ordererd mine thru NGK.com and on the bill it even warns do not gap them.

I found the following in the FAQ on ngk.com:

Should I gap my Iridium Plugs?

The manufacturers say NO.
This is because most people do not know how to properly gap a spark plug, and the center electrodes on the ultra-fine iridium can easily snap if mishandled. There is no warranty for snapped center electrodes. The manufacturers say an iridium spark plug will run so much better than a traditional plug, even if it is not gapped for that motor, that they would prefer you just leave it rather than risk snapping the center electrode.
Personally, we at sparkplugs.com, gap our iridium plugs for our own vehicles (we’re rebels). If you insist on gapping your iridium plug, please refer to Proper Gapping for instruction.

anyone wanna chime in on the best method for cleaning a spark plug ? I know it's a really newbie question but hey I am a newbie!

I've found a wire wheel on a drill motor cleans a plug very well.
