Jetting and spark plug experts please help

[nestz]

Hi all, I'd appreciate some help with this. I Recently purchased a brand new 2014 xc300 and ran the motor in over a few hours mainly going from low to 3/4 revs with the occasional wot, then checked the plug and it appeared to be on the rich side (bit oily and darker sort of a tan). I put a fresh plug in yesterday and rode sand dunes giving it everything for an hour then checked the plug. See pic attached.

Im no expert but is it looking too lean? If so where should I start?

Thanks in advance for any advice.
