Default heat range 6 plug 77 sporster

Hi, possibly a dumb question but I moved to these plugs for my 1977 ironhead with electronic ignition after having some issues with others but now I'm wondering if the heat range is ok, as it says 6.

Wondering what the community thinks and also recommended gap if possibly different from manual.

I run NGK 6222 (BPR5HS) plugs in my 68 XLCH that I converted from mag to a volcanworks distributor. I also found that the BPR6HS plugs foul too easily. I gap them at .040 and use a .060 indexing washer to correct for the difference in reach over the stock 7/16 reach plugs. Plugs work great for me using S&S Super E with .0280 intermediate and .066 main jet.

No it doesn't replace the regular plug washer as far as I know. I just add the indexing washer. They come in multi packs of various thickness up to .060 or .062 depending on the brand.

Indexing spark plugs has been discussed here a couple of times, but not recently. The idea, I believe, is to add one or more spacers to change the direction the spark faces, to get a better burn, and consequently some increase in horse power or whatever

Mick I use copper indexing washers (.060) solely as a spacer to allow me to run the NGK projected nose plugs in an early IH without fear of reach mismatch. It was your posts about NGK's that made me want to try them and they work great. Wish NGK made a projected nose plug in 7/16 reach. All of the indexing washers that I've seen (they all seem to come in multi packs in several sizes between .020-.060) are IMHO really too thick to use for their intended purpose.

Great choice of plug, however I would not use a washer.
As long as the plug does not hit the piston you are good.
I believe it is an advantage to stick the electrodes as far into the combustion chamber as possible as the short plugs sit back in a hidey hole recess. (which slows down flame propagation)
I would only use a washer if the threads get carbon'd up and make the plug hard to remove.

Oh, Drag does not make spark plugs, they are a distributor not a MFG.
And I would not buy plugs that have a colored insulator as that is a compromise, that is impurities in the aluma to make the color.
