    Looks like there's an increased likelihood that you have coolant entering into your engine.

    I had recently performed a clutch friction plate replacement on my XJ550 and wiped out the crank case ventilation passageways. They were just barely milky and with the condition of my bike overall - very doubtful they had ever been touched. <--attempting to convey that its probably not PCV related.

    Will recommend a cylinder compression/leak-down test once more. After all of your efforts so far, a head gasket should be a breeze. You got this!

    If the head it leaking then you should be able to top off the radiator. Put the bike on center stand, leave radiator cap off and turn the bike over. If you see air bubbles coming up then it is a good chance you have a leak. I know that when I was working on my X, I pulled the head and found that 1 & 2 had small leaks going on. I honed and put in new rings while I was there and checked replaced the valve guides.

    Another "Airhead" way is to remove the coolant and then try to start the motor. If she starts and no smoke, then you know that it likely you have a issue. Compression test and or leak down test should be done too.

    Bottom line, I would mentally get ready to pull the head off and do it right. My X sure was a nice running bike once I completed the hone, rings and gasket.

    I wouldn't want to start my motor with the oil situation Joe described.

    You will have to ride it for a while to get a good plug test, IMHO. You don't have white smile or smoke smell a little sweet? That would be a sign of coolant being burned. As for the one plug not being wet...I would pull the connectors from the back of the carbs to the air box. With it running, I would hold my hand over that carbs air inlet area and see if you hear the bike start to rev a little more. I know you have taken them to church and been going nuts with them, but the plugs are saying there is no fuel there. Putting your hand on the back of the carb will force it to over choke and that way you can see if you are pulling fuel from the bowl.

    If there is no fuel burning in the cylinder, the exhaust pipe will also be cooler then the others. Be careful checking that with your hand use a laser temp reader if you can. But that will tell if fuel is getting in there and you are firing as well.

    So here's what the compression test told me.
    #1 90psi then jumped up to over 100psi with drops of oil.
    #2 is around 130
    #3 is around 100
    #4 90 but jumps up over 100 with drops of oil.
    The bike does not burn a drop of oil.
    And I cannot get access to a leak test.

    you could have stuck rings or worn out rings in 3 cylinders.
    problem here is that if you have a coolent system leak it would also show low compression.

    you may have to go to a bike shop for the coolant leak test.

    is any oil showing up in coolant this does sound like a coolant system issue

    With numbers like that, I would certainly heed the advice of @XJ550H with coolant pressure testing. Might the "brand new" spark plug be number 4? Steam cleaned spark plug perhaps? You are getting closer to the core issue(s)!
