"Iridium?"

[rks]

Hey Irish, have you checked the Harley Forums, for what others with your engine use?

This is what I did, (but I went to BMW Forum) and found several recommendations for an Autolite 3923 plug, for my particular bike. This was a little more than 2 years ago, a two pack was $3.21 at Wallyworld. Still work fine, but I have only put 6,500 miles on them, so no big surprize.

My scooter is still running the standard NGK that came in it. I have suffered no power loss, or decrease in fuel mileage, yet.....8,300 miles.

Some swear by iridium, or the Split Fire (that was a big thing a while back), I've just never seen the need. Probably a generational thing.....you know....the old dog, and new tricks, kinda deal.
