White smoke, Oil, Power Loss. Help

I know if you leave one of the breathers off you'll get a lot of oil everywhere but that doesn't explain everything else.

One way to see what it is, is taste it, lol.
If its sweet its coolant, not recommended though if its oil, lol.

Coolant wasn`t changed recently was it ?

The pressures you have are a bit high, if that is oil spraying around it's possible that some has made its way into the pots, I have previously seen this and the unusually high comps it gave - the oil reduces the chamber volume and causes the numbers to rise.
Does it run OK when cold? If yes then the problem could be head gasket related, and there's the slimmest of possibilities it only fails to clamp when hot, but I doubt it. Unless another comp test gives much lower figures I doubt there's a problem with either the head gaskets or rings/cylinder interface, if there were then there's no way you'd obtain the numbers you have done so far.

What's the coolant level like?

This may sounds strange - but I just checked the oil level of the bike and it almost seems as if the oil level is going up? Is this possible? Or am I crazy?

Tasted and Its def oil

What's the coolant level like?

The coolant level looked fine. But that was from a visual check in the radiator and the reservoir. is there a proper way to check?

I haven't started it since this happened. Should start it up and see how it runs? What would I be looking for?

I am not trying to be derogitory but you are checking the levels with the bike in the upright position and not when on the side stand. If you have recently topped up your oil is it possible you have overfilled it? are all the breather pipes clear i.e. not blocked internally, thereby increasing crankcase compression.

I am presuming the engine turned over without resistance with the plugs removed when doing the compression test

Theres a point, how do you get the bike to stay upright with no centre stand ?

Check the fluid levels first, be sure of what you're looking at, for instance just because there's a fluid in the oil window don't assume it's oil you're seeing - for instance it could be a mixture of oil and fuel. Take the radiator cap off and make sure the radiator and expansion tank have fluid in them. Again are they contaminated?
Take the plugs out and turn the engine over manually, if no unusual noises or problems in doing so then after making sure everything is connected properly try to start the engine. There will clearly still be some of the oil that the motor has ingested present so don't be alarmed if there's a bit of smoke initially.
Don't rev it excessively, what happens? How does the motor sound? Unless it sounds wrong let it warm up to a reasonable temperature, still smoking? How's the levels?

I started it up this morning. I have blue thin exhaust at idle, and then when i twist the throttle, it turns to thick white smoke -- and I can definitely smell the coolant. Im hoping and guessing that its a head gasket. And it just blew in a way that both oil and coolant are leaking into the chamber and burning. Thats why i cant see a mixture within the oil window. Im going to do an oil change today to see if any coolant made it down to the crankcase.

Any thoughts?

Regarding tearing the motor down - Do you need to replace the Cylinder studs? I've heard that they expand and may need to be replace. Just curious on your thoughts...

No worries - I did an oil change about a month ago and have been riding with no problems. And i've been checking with the bike at level. Not on the side stand.

Thanks again.

They are bolts not studs, AFAIK the manual does not say to replace them.

Ok.
So i removed the engine last night and this morning i tore into the motor. Here are some pictures of my progress.

The head gaskets to me, looked damaged -- but let me know what you guys think. Also take a look at the valve pictures and piston and let me know if i should clean these up. Overall, they dont look too bad, but I really dont know what to look for.
