Head gasket...... possibly warped head.

How far did you tear it down? Remove head cover (#18)? Remove head (#1)? I'm thinking if you actually pull the head, you'll find coolant on top of the piston. If you've only removed the head cover, exposing the valve train, and you have coolant present there, it could be several things including cracked head, valve guides, etc. That said, symptomatically the coolant has to be entering the top end somewhere, hence the reason for expecting a bad head gasket or cracked head (into the water jacket). If coolant is present up top, in cam area, one of the valve guides could be burnt/worn, and leaking coolant under compression from cylinder into top of head (along valve stem/guide to top-side cam area). Make sense?

You might also want to check your crankcase oil to make sure you are not introducing coolant into bottom end (oil will look like frothy light brown mud). That would indicate possibly cylinder base gasket failure or cracked cylinder water jacket.

Okay, back to square one. You filled up your radiators.
How much coolant did you need to add?
Did you notice any fresh coolant on the ground or on your bike stand?
Can you tell if you are leaking anywhere externally (i.e. water pump weep hole, hoses, etc.)?
What is the level of your oil? Was it suddenly "over-full"?
Was your bike running noticeably hotter than normal before you added coolant?
Did you notice the rad cap allowing coolant/steam to spew out?

I'm trying to figure out why you got to where you are.
Thinking out loud....
Water pump seals / bad impeller shaft?
Water pump shaft inner oil seal failure could allow coolant into crankcase. Outer water pump seal failure should have given you a telltale at the weep hole.

See where I'm going? There had to be a telltale of what started this.

You've most likely overheated (could have been a bad water pump or shaft seal or leaking hose/radiator), toasted a seal or popped a gasket, gotten coolant into your cylinder, and now showing signs of coolant in your crankcase. The reason it's hard to kick over is that the cylinder is filling with coolant. Coolant in your oil could simply be the head or base gasket allowing oil/coolant to mix whever the gasket(s) have failed. The coolant AND oil run through the head. Remember, you have a valvetrain up top that requires lube.

You could try all new gaskets, check your water pump thoroughly, make sure your oil pump shafts are intact and functioning (pumping and scavenging oil), clean filter/strainer, change your oil (should be flushed at least once with any previous signs of water), re-assemble, adjust valves and timing, compression test before firing and/or cylinder leak-down test, etc., etc., etc.

Do you have a shop or repair manual? If not, get one. If you cannot get a factory book, settle for a Chilton or Haynes. At least it will help point you in the right direction for tear-down and re-assembly. It will be 25-30 bucks well spent. Remember, all the parts in your motor have certain tolerances/service limits to make it function and perform properly. You can't guess on what's right, especially your first time.

Or, take it to a reputable shop.

Is this your only ride, or can you take the time and afford the cost to make it a learning experience?
