Any of you guys running these in your tri glide ? I ran them in my last bike because it had two plugs per jug and you had to pull the gas tank to change the plugs, just like you going to have to do on the new engine HD came out with.

I can't speak to the M8's, but on Twin Cams we did a lot of testing several years back with several different brands of Iridium plugs, including the HD brand.
None of them performed as well in the 3 Twin Cams we tested (2 EFI and 1 carbed) as the OEM plug.
Sort of surprised us, but it is what it is.

I have checked a lot of plugs OHM wise
I have found huge scale readings from many
I like Iridium plugs
The Twin Cams did not mind them too much(I ran Autolites)
I can get my M8 plugs out with out lifting the tank on my Freewheeler, I dunno about a Tri Glide
Basically the same sub frame up front I believe. Thus, the tri should be no different. Now that I own two of the critters, it would be in my best interest to query my indie. And, are things starting to return to normal over your way ?
Yes, how r things in Texas
I would add to this
The ion sensing in TC and the M8 can and do detect spark knock thru the spark plugs
The M8 has knock sensors also and can advance and retard timing better
IMO the HD plain Jane or Champion and Autolite plugs are the best choices
Stay away from splitfire and fine wire lectrode plugs they can and do cause BIG problems
Like i said before, From 64/65-68/ 69 i would cut back my plugs electro's, Champions J6 I picked up that trick from Sox and Martin...
And that would knock off about a 10th of second off my 1/4 miles times, a lot of times that was the difference between winning or losing.. But after about 5 runs my times would drop off....So five runs' pull them and toss them..
End gaping, a little used any more racers trick
I remember doing this and indexing too
I could / would index for the first run, After that pulling 8 plugs around hot spaghetti headers between runs and trying to index them was a no-go..:Shrug:.
Yup, for the plus maybe 1 hp not really worth the effort any more especially with the modern fuels being what they are now
