Yep, don't gap them.
I noticed a huge difference, but my bike was not running that we'll before I tried them.
After my engine rebuild and carb tuning, I tried them again and didn't notice a difference.
I've heard people say it's best not to touch those plug gaps and just run them as-is.
I have been so tempted to try those. Everyone that runs them seems to love them, but I tried a set in my '76 and it didn't like them at all. Pretty sure I'm the only person with a bad result with iridiums.
A free people ought not only be armed and disciplined, but they should have sufficient arms and ammunition to maintain a status of independence from any who might attempt to abuse them, which would include their own government.~George Washington
