What are the specifics of your bike - year, model, engine, etc.???

Here is a link to NGK's website where you can do a search (if you use NGK plugs):

And yes here they come. Check the gap on the new plug. Dont trust the factory worker who gapped them. If you do have to gap the new plugs its .035.

And another ,
I worked in an automotive parts warehouse for 15 years . I think it is insane to not check the gap on a plug after seeing the way some parts are handled , even if they left the factory correctly gapped .It only takes 30 seconds to check the gap on 4 plugs .

and yet another ... people return things. You don't know the last person didn't drop it or re-gap it before returning it. You asked

Why trust the performance of your ride to another when, with 2 minutes of your time, you can guarantee accuracy of your plugs and remove that variable from the equation if trouble ensues?
My only comment!

Standard copper plugs are fine to gap with no problems, but the laser platinium and iridium plugs are easy to damage if you use the wrong type gapper/feeler guage. its not recommended by the NGK or Denso.
and if I were putting in some AC Delco or champion plugsin my domestic vehical I would most deffinetly check them, chances ore they are way out and have been dropped.
Thats one the differences between the US and Japanese manufacturers.

True, and I dont trust them to gap my plugs. Using a wire type gauge is the way to go to make adjustment to the gap.

Here is how NGK says to gap iridium plugs
https://docs.google.com/viewer?a=v&p...NmNkNTQwMjc1OQ

On my '98 1100 Shadow when the starter is working I have a weak spark at the plugs. So I gaped the Iridium plugs at .030 and it starts right up, all year long. When I gaped them at .035 my bike was hard to start in the winter(all the time) and hard to start for the first time of the day in the summer.

I use the feeler gauge like whats in the middle pic. I would never use a slide gaping tool.
