Can you use that plug with the stock spark plug wire? All I'm looking to do is to swap the old spark plug for the NGK spark plug using the stock spark plug wire. Is there any real gain using the iridium plug vs the standard plug? I would understand if this was a high performance engine. But is it worth putting the Iridium plug in?

Yes, the BP6ES has a screw-off tip.
Iridium plug is supposed to last longer, and it has a very thin electrode which theoretically might make a less obstructed spark kernel. It depends on if you want to pay nearly $20 for a spark plug, or not.
People were putting them in an attempt to improve the idle stability. If you have a Power Commander, I don't think you need an iridium plug.

Iridium lasts longer, that's about the advantage and probably not worth the money.

Amazon has them for $6.99

On various Japanese bikes, every time I switched to an iridium plug, the idle speed went up 500 rpm.

Just picked up the standard plug for $2.49 at NAPA Auto Parts.

Huh. Interesting.

Maybe we are giving too much importance to the type of candle.
The fund only has to make a good spark to ignite the fuel and nothing more '.
So I think for our motorcycles candle iridium and 'wasted.
For example, on my bike and I have a BPR6ES NGK and 'ok, and no PC installed and the idle speed is stable, as shown in the accompanying video

Freddy1 - I've commented on the misleading title.  But that aside, am I right in thinking your bike doesn't have a lambda sensor?

[Freddy1]

Congratulations Steve.
The lambda sensor and 'present but not active.
Since the topic of this thread the spark plug, to avoid confusion, I prefer to start a new topic as "simple and low cost method to disable the oxygen sensor."
