puke Blue smoke! help!

I noticed that I was blowing a bit of blue smoke under throttle (burping) when i checked the oil before my ride today.. Nothing major - but it was enough to make me notice -
The we started down the WET trail and i got mud up to the airbox - and a bit got in. I made it through the mud but i wanted to make sure i got the small amount of the mud/water OUT - so we stood the bike up on its back wheels to get a little bit of mud out...
Then we went to the track and under high rpms - the bike initially seemed like it wanted to puke out on me at the top of any gear... I just kept going and thought the air filter may still be a little wet - no biggie right?
Well, we continued riding but another rider stopped me to alert me that i was burning oil...Sure enough when I get on the throttle you can see blue smoke, you can also see it when decelerating... Not so much at idle... Once I had to turn around on a trail and go where I just came and the whole trail smelled of burnt oil. Rear tip of the exhaust definately looks oily.
Maybe this is from standing the bike up on its back wheels?
Should I be freaking out??? Vavles? Seals? Guides? etc? OR should I just change the oil and clean the filter and see how she acts?
My 700xx is not stock. It does have the "big 3"

Buy/borrow/or rent a compression tester. Look up in the manual what the psi should be. Pull the spark plug and install compression gauge. Turn on the key and open the throttle all the way. Hit the starter and hold it as the motor cranks until the gauge stops increasing. Check that to specs. If low, then remove the tester and poor in a small amount of motor oil in the spark plug hole. Repeat the test. If compression goes way up the rings or cylinder wall are bad. If not, then probably the valve seals. Start with that.

if the smoke doesnt clear up after standing it up to drain it then you got a prob, either bad rings or valveseals maybe time for valvejob and piston and rings and may have to bore or get a cylinder works kit

Thanks for the responses! Do you think this is a result from any water getting into the airbox? Does water cause these issues? Additionally I never had the 10 hr service. I just keep good oil in it and go!

Do you think this could be a direct result of my "big 3" addition? Never tuned or dyno'd...
Ordered my alba programmer to go with my full exhaust and vortex filter.

It's possible. Our quad is a bit lean from the factory and adding the big 3 without a programmer will make it run even leaner. Running lean will make you run hotter and can cause damage.

I've always been all about keeping things "bone stock" in the past but a friend talked me into doing the "big 3"... So now I have these issues? I put them all three on at the same time. Would you say that there is a level of possibility that doing anything other than stock could lead to this?

I think you got some dirt in the cylinder and ate up the rings and/or valve seals.

Too much water coming into the cylinder will create huge compression increase and will blow out something. Head gasket if mothing else. Generally is a catastrophic ending. Don't think this is the problem.

Sand in some water being sucked in could have caused rapid ring seal failure though. Definite possibility.
