Reach out to Wood Butcher on Facebook.  He has detailed the procedure there.  I'm not sure if he is on this forum or not.

I'm not aware of a how-to for the hydrolock repair, just postings in the forum.

Maybe a good time to start and post one?

I am just wrapping mine up, and have a couple hundred pictures, I think. Send me a message and I'll see if I can share the link with you.

Did you damage the motor or just lock it up?
If you just locked it up pull the plugs pull the bike outside tap the starter it would be a good idea to cover the cylinders with a rag as it will blow gas out many of the holes! 
Check the dip stick if it is high you need to drain the oil ASAP.
Replace the filter and top of the oil I would use the cheapest stuff you can find!  put plugs back in leave the plug wires off tap the starter make sure it turns over freely.  Assuming it turns over snap the plug wires back on and try to start it.  Let it run for a bit make sure everything runs smoothly if it does put a few miles on it and replace the oil and filter again with good oil!

The real question here is why did it lockup and what have you done about it to correct the issue?
If nothing then you need to address this first!  (however I would check the oil and drain if needed)
I had this problem several months ago it turned out I had a bad petcock which I replaced I made the mistake of buying a cheap replacement which I plan to replace again in the near future with an OEM part. 
Best of luck!

A hydrolock requires three elements to line up.

A petcock needs to flow when it shouldn't.

A float needs to fail on at least one carb.

The engine needs to stop with the intake valve open on the cylinder with the failing float.

To completely repair the hydrolock one needs to address the two of these failures.

Thanks everyone for the feedback. Finally had some time today to work on her since the incident (getting married, moving, buying/assembling new furniture, and starting a job really hindered my time  Shocked)

I did as everyone recommended - confirmed fuel in the cylinder and it blew out after removing the plugs and engaging the starter.

Checked the oil and it appeared fine. Starter spins freely. Appears I had just locked it up. Confirmed that she will start now without any issues. No apparent damage.

Going to rebuild the petcock this weekend and do an oil change tomorrow.

glad it wasn't a bigger problem!  I have taken to turning off my petcock every time I turn off the bike. 
Congrats with the marriage plans.

Unless you're busy riding the bike, wait on the oil change till after it's been fixed.

Just because you have gas in your line, doesn't explain how the gas got pass your float.  you need to determine which cylingder was leaking and why. I've gone thru this 3 times, once I found the cyclinder that was leaking . I place a wooden block under that carb and tapped on it a few times to jar the needle valve, sometimes its just dirty lodged in it, each time this happen and it was on 3 different bikes it cured the problem and I hadn't had a problem with any of them doing it again. Don't put it back together and try to start it.  Wait a night with it buttoned up, then pull the plugs the next day and see if it sprays gas, if it doesn't you should be good to go...if I remember correctly I did this several times just to make sure it didn't happen again.
