    The bolt covering the clutch oil jet seems to be seized. Any tips on how to get it loose? Already soaking in wd 40 but fear destroying the head when trying too hard.
    Torch is not an option I guess?

    heat can help. Make sure the head is cleaned out and your allen key fits well. Penetrating oil works much better than WD40 fwiw.

    Have you tapped it with a small hammer. Rapping it pretty solidly several times directly down on the bolt may break something loose. Also have you tried tightening it before switching the ratchet and loosening it. Sometimes just a small movement of the bolt in the tightening direction and then swithing to loosening helps with any seized bolt.

    Have you ever had he bolt and the jet out in the past? If not when you get the jet loose and if it doesn't come out directly I found that I had to use a quick shot of compressed air to get the jet up out of the hole. I thought of using sticky substances (silicone, grease, ets) on the end of a probe but that didnt work and I was afraid of getting the substances stuck in the hole. One quick shot of compressed air and the jet came right out.

    If you can ,maybe ride the bike first and get everything warm.Try shocking it first with a bolt or punch ......good luck.

    The bolt is out here, but this is where it goes. And, the tools shown here were, for me, the easiest way to unscrew the jet.

    A sharp knock with a punch and hammer usually does the trick, you have to do this with the KTM EXC's as well.
    Having the engine warm may help as well.

    Just grab it with a needle nose vice grips. It will snap loose easy.

    soaking in anti seize oil right now, next: tap with the hammer. If that doesn't help, vice grip.

    Riding it hot is not an option at this moment... bike is apart for maintenance :huh

    Has been out a few times before, until now, it was never stuck...

    You could always cut a slot with a small zip wheel or hand saw with some patience. After slot is cut just use a big regular slotted screwdriver.
