The engine was not hot when I took these out, been sittin for a few days actually..I've heard both ways whether or not I should remap it. I've heard the front cylinder is way lean and then I've also been told that it wont hurt anything to run em like they are, so I'm not really clear as to what I should or should'nt do...
Judging your A/F by those plugs is worthless.
You'll NEVER see 2 plugs identical on a Harley, (color) with the degrees of firing this engine has. The rear cylinder is always richer to some degree, just based on the location of the cylinder in conjunction to the location of the intake. The natural progression of the fuel is rearward....
Unless you're using MULTIPLE sets of plugs, and doing a throttle chop method, you'll NEVER gauge how your bike is running by a set of plugs that's been in the bike at idle, tooling around and highway use, collectively.
You'll hear 257 different opinions on why your bike is running by looking at those plugs, and they're all about as accurate as pototo salad and a spoon at a rifle range.
If you *THINK* you need to remap, you probably do, because something is leading you to that thought.
If you've done ANY mods to the bike including free-flow airfilter or exhaust, you definitely need to remap.
If you doubt this at all, take the bike and have it put on a Dyno with a minimum 2 gas analyzer, and I'll bet you the cost of the Dyno run that it's Lean in the 2900-4800 range, with a huge flat spot on the A/F line.......
Even STOCK Twin Cam bike could stand to be remapped as it has the same flat spot and lean mid-range area. That alone on a stock, twin cam bike will make the bike feel like a different machine......
