2011 EC300 jetting issue

[Rampart]

hi all
Need help with jetting please.
Gas is 100% stock.
It runs at 330 feet, +20 celsius. 170 main and 38 pilot with CCK needle at first clip (leanest)

It runs good from idle to all needle range. But way too rich at WOT. Obviously main jet is too big. Electrode is dark (rich). BUT i don't find examples with smaller than 170 and 40 pilot, so i can not understand - is my jetting simply rich, or i have some other problem?

Interesting, that i was riding two days before with stock needle and 170\40 jets, and it runs good at all throttle range. All that changes - it temperature, it grows from 5 to 20 celsius. It was only two times i ride on new bike for now. So i confused - can it go so rich because of the temperature??
