Going to try some NGK iridium plugs in my 74 t150. #7's or #8's?
Otoh, I've used NGK's exclusively since about 1979 and never stripped a thread in any head, Triumph or other. Mind, I also always fit plugs with a little Copaslip on the thread, after cleaning any thread on a plug being reused.Opinions are a dime a dozen,
$8.19 each at Advance Auto here in NY, between $7-9 from all the other discount stores online...You're getting a deal...I've been running NGK BR8EIX plugs on my 73 T150 for years. I pay $3.50 for them at Advance Auto. Bob
I did not know this, I’m searching for the 13/16 long socket and feeler gauges now.A larger gap may help with off idle hesitation..
If the engine goes slightly lean off idle it may help...Hi Truckedup

Oh I believe it... There is some talk that fine wire plugs have a smaller spark kernal than a conventional plug..I'll see if I can find the info..It seems to make a difference in stock bikes and bikes with minimal mods like air filters and exhaust. There are measurably less hydrocarbons suggesting a better overall burn.
I do know it made absolutely no difference in sohc Honda’s any way I tested it.
..must be a chamber design thing.
