How did the bike run? I haven't did plugs on my Guzzi and probably won't for a long time. I quit changing the gap on my Ducati GT 1000 NGK plugs years ago. They were always the same. I checked them but never changed the gap. I decided consistency was better. The bike takes 4 plugs and there was never a variance. You can't do that by hand. If you measure with a feeler gauge it becomes a choice. With a wire, it becomes another choice. Whatever floats your boat. It's all good.

.65 to .7 is a whole 2 thousands. Not worth worrying about.
The manual does state 0.7mm and 0.8mm plug gap. the NGK LMAR8EI-7 has a gap of 0.7mm out of the box. The service manual also states that if the gap is outside of specification then replace the plug. So which gap is correct?
Piaggio have a lot of work to do to match Japanese service manuals.
A statement made for decades. You are far from the first. That is what this Forum is here for, for public consumption.
Spark plugs is spark plugs, sorta. All need them to do is 'spark' & fit in the hole, and at least can get to next destination, hopefully.
If doing a service prob want to get the 'correct' ones, which as mentioned about seem to be used on scooters also.
Iridium plugs last 100K km's (apparently), but if just want a couple of 'same thread' / will go in & should work "standard' plugs, then looks like a Yamaha shop may be able to assist. WRF 250 ?
I like to carry a couple of correct spares, but in a pinch, this info may assist: (fwiw this size & fitment seems to be 'rare' (like 26mm axle nuts on a V85TT ). I can't find any 'automotive' fitments.
