Hi guys,

I'm not a plug reading guru by any means so looking for some info from people that know what they are looking at.

These 2 different plugs (first copper, 2nd iridium) are new out of the box and 3 passes old (couple of minutes of wide open throttle, then turned off straight away and checked)

Motor details -
Tohatsu/Nissan 50hp (700cc 3cyl 2stroke)
Shaved head
Ported
Tuner
Reeds
Standard airbox
revving to 7000rpm

I think they look a tad lean?

Thanks in advance
