I've always heard that squirtin' a fine mist of water into the carb will clean out the carbon. Always made sense to me. I seen enough engines with blown head gaskets, where the coolant had leaked into one of the cylinders. They were always nice and clean.

Beside, if it don't work, you ain't spent a bunch of money on it.

GOC, if you want to cut carbon, drop in a can of Seafoam additive. Originally made for 2 stroke boat engines which are carbon pigs...will clean the crap off a lot quicker.
will not hurt anything like lines or plastic floats either.

Installed those plugs last night and was impressed.  They seem to have a slightly longer reach, maybe .050-.075. The electrode is gapped to .040.  Now I will tinker with the carb jets on phase II of working on something that didn't need to be fixed.

Yep, I added some MMO to the gas too. It will remove the cholesterol from the lines, and help decarbon the two hearts in my XX Ironhead......someday I will have an XY Shovel.

Dave, don't you use the Fetch that I used to sell? My gas never gets old with that chunk of shit in the tank.  Tonight I may give the bike a shot of Marvel Mystery Oil in the oil tank too.  Iridium is viagra for the top end, Marvel is like Jack and lubes up the bottom.


No, I never got started on the Fetch. I vaguely remember you selling it. That was a long time ago...

I know these aren't split-fires. I was just explaining my skepticism. I know that the Iridium plugs are supposed to be great. I believe that's what's in my Mustang. The original set in that thing went over 100k before they started misfiring. Can't complain about that. They've served me well...

Marvel Mystery Oil? LOL, I used to run that stuff in the gas in my built VW motor. Had the sweetest smelling exhaust! Old-timer I worked with recommended it for adding life to the top-end. Never had a problem with the top either. Good Stuff...

I used E-3's in the Electra glide and was well pleased with them, seems they didn't foul up near as bad as the ones Harley put in it. No special tools needed.

dave the 05 f150 i hqd and the 13 f150 i now have have those plugs you mentioned , with out the special tool to remove them you crack the insulator part making them almost impossiable to remove with out the other special tool , or so my mechanic buddy tells me . split fire plug,s have been around for a while, no better than a regular one imho.

Ever since they introduced "Split-Fire" plugs, I've been a skeptic. When the guy behind the parts counter made the claim that they unleashed gobs of horsepower. I was ridin' a 4-cylinder Honda at the time. I fell for it and they turned out to be a waste of $20.00...

But, I got some sort of fancy spark plugs in my 2005 Mustang (GT 4.6L) Damn things are about $10.00 each. Funny lookin' plugs too. PITA to remove because they tend to break. Shit, they even have a special tool for removing the broken plug.

Let us know how they work out for ya...

I am installing iridium plugs.....nope, didn't inherit a fortune.......I am just seeing if they solve the intermittent burps and farts on my girly ironhead.

Then I will adjust valves, maybe tinker with the SS shorty too.   The gap on normal general population plugs is .040.  I assume the same for iridiums.
