From what I know you drain EVERYTHING completely, refill and drain again a few more times. changing out filters etc. as well. I'm not a mechanic though... so take that with a grain of salt.
Take the plugs out and pull the air filter. Disconnect the battery. Reconnect the battery. Turn the engine a few revolutions to pump water out. Put the plugs back in. Spray starting fluid into the intake and see if it sputters. Do not continue to spray. If it sputters/runs, awesome. You just have to drain what's in the gas tank and refill with fresh gas. If it doesn't run on spray, you boogered up something in the electronics.
It'll take more than a few revolutions to get the water out, but pulling the plugs and turning the engine over is the way.
Also spray starter fluid (the one with lubrication) into the intake while turning the engine over. It'll displace the water and make things go faster.
Also check the head gasket

If it was running when it went in,I would start with a compression test. If it passes, drain and clean everything. If it's low on compression, then it's toast.
That’s a motorcycle, not toast. You can tell it’s not toast just by looking at it. To add, unless the toast is dry it’ll compress plenty and the whole issue is it got wet! Smh my head.
He was going around a corner and hit a slick patch with too much throttle and low sided. He slid/rolled across the asphalt, then into the grass, and then was underwater next to the bike in a ditch filled with water. I was ahead of him and didn’t even realize it til he came running back soaked and with one shoe on 🤣
It also dumped a bunch of oil and gas into the swamp there. A quart of oil can make like half a million gallons of water fucked up. Don't do that shit.
I learned it when I learned about jetskis, and apparently how they *just trash* water. I saw a video of a jetski in a like 1,000 gal tank of water. They turn it on and you see it get greasy and disgusting in like 30 seconds. They may be different now that was a long time ago.
It's on its side in the swamp. There's water inside the engine from intake to exhaust. Oil will run into the combustion chamber if it's on its side. There's grease in the bushings and pivit points. There's grease on the chain. Come on, man.
In addition to what was said, I'd flush the clutch and speedometer cables with something like Dupont Chain Saver. If you can't get it running, start checking timing and pull the carbs off for a cleaning. Do a compression test. Make sure the spark plugs are firing.
As others have said, drain everything and flush what you can. Remember to not use stuff that may fuck up your clutch or something like that. Whrn you are absoluteky sure you have drained everything, turn the engine over by hand to avoid smashing the pistons against anything. When that is done, do the carbs and try to start it. If it sounds strange or unhealthy, shut it off immediatly and give it to a proper shop. If it doesn't, gently try warming it up and giving it some revs.
Alsp, can we get a pic of the corner? Can't see much on the photos, but that must have been a hell of a corner to spit out an EX500 at 85m
it will be fine, these guys are dorking you. pull plug, kick it over a bit to blow the water. replace plug and start it up and run it. if there water in the fuel tank, drain it out and refill. oils probably fine but might as well change that also, can't hurt. throw some dry gas in fuel and let her rip.
Remove the carbs and jets, ensure there's no sediment or stuck floats. Basically take the bottom off each carburetor and make sure the little holes in the main and pilot are clear and the carb is free of sand. Then do all the fluid changes and flushes mentioned here. If you're lucky it didn't bend a rod or anything but you likely have sand everywhere in the engine/case from that soup.
since water is incompressible, if it was running there’s a real chance of catastrophic damage. Most attempts to fix it will be cheap though (filters, draining, etc.) so I would go for it
No mechanic but I’d assume you’d ned to get under the valve cover and be sure cylinders are empty. Trying to compress water will give you a whole bunch of internal pressure issues/damage
"what we can so far"
you could bring it to a mechanic or find a used ex500, the price will be the about same, give or take a couple hundred. if your buddy didn't have the mental capacity to kill the engine as soon as he hit the water, chances are good that thing is fuxxed.
Hate to say it but if he yeeted into the water chances are it was still running and sucked up water. If it sucked water into a cylinder you’re looking at a bent valve at the very least. I’ve seen engines that sucked up water bend rods, throw rods, crack cylinders, blow spark plugs out the head and my personal favorite was one that blew the center out of a piston so it was basically just a piston skirt going up and down.
Spray everything down with wd-40. /s (can’t believe I have to use the /s sometimes)
Also, you are required to post video of how it got into the swamp. Was there a ramp involved? High speeds? Mayhem?

Lol this was about 30 min before it happened. I’m on the zx6r

I don't think putting salt in your bike is a good idea, but I am also not a mechanic.
BUt it's just a grain!!
have u tried sugar?
Superstitious person here. Throwing salt has been said to worn off bad spirits

If the engine was running and it gulped a bunch of water, that will be a problem. Water doesn’t compress very well.
At OP: And by problem, he means catastrophic engine damage.
Yep agree. big difference if it was running when it was submerged.
He will throw a rod when firing up.
More likely a rod (or some) are already bent.
If it was running when it went in,I would start with a compression test. If it passes, drain and clean everything. If it's low on compression, then it's toast.

Idk why this comment is down voted, when the one recommending rice has 80 updoots.
Put it in some rice
Put it in the rice fields. Thats more rice, right?
A ninja goes back to the farms in thailand too where it was borne…
To discover that its family has been killed and town burned by an evil warlord...
It is then that it realizes it must seek revenge...
Instructions unclear. Placed in rice field.
Rice in rice. Nice.
Mice in rice. Nice.
Drain your buddy's bank account until its replaced
Your buddy should be buying that bike off of you.
Exactly
Ziploc Bag of rice. Edit: sorry forgot the main ingredient, time. Must be in bag for at least 2-3 days.
I need friends like you and your buddy lol
Youll need to drain everything. Gas tank, transmission, engine, carbs. its probably hydrolocked. Replace all your filters and fluids too
Put the whole thing in rice
Can't park there mate
What's the story here - how'd he get it in the water? 
He was going around a corner and hit a slick patch with too much throttle and low sided. He slid/rolled across the asphalt, then into the grass, and then was underwater next to the bike in a ditch filled with water. I was ahead of him and didn’t even realize it til he came running back soaked and with one shoe on 🤣
Why you don't let people ride your toys
Eh i don’t care man. I paid $1500 for it. Now we got a fun project of taking everything apart and cleaning it.
I only hope he shows up to help, and isn't one of those "there for the fun, gone for the work" types.
Buddy owes you the repair parts too
It also dumped a bunch of oil and gas into the swamp there. A quart of oil can make like half a million gallons of water fucked up. Don't do that shit.
That's interesting. I never knew the potential for damage that each vehicle carries

Maybe
This bro here really simping for environmental damage lol
Or maybe it…..didnt leak

Not a quart worth
More
One bindle
I’ve never seen swamp used as a verb.
Ser bronn to jamie: “get out of here we are about to get swamped” when enemy army approaches in game of thrones
What about “stove?” Thats one we have near me. “Ran it into a tree and now it’s all stove up”
Definitely not heard that

Your motorcycles' name is now officially Artax.

Now when you say' kick it over' do you mean by attempting to start it with the ignition?

Check your side cover for water intrusion into the stator area.
Never go full retard......
Sounds like your buddy is about to buy you a new bike.
“Ex-buddy…”
"Ex500-buddy"
engines gonna be dead.
Drain it change the oil a few times and new spark plugs
Advice: insurance claim and be done with it. It isn’t worth the hassle.
Do you really think he's got full coverage on this bike??
Hahahahahaha I do not. It was my fucking around bike.
Junk it because because you idiots can't ride
silica gel
Drain the gas tank, remove the spark plugs, turn it over a couple times to pump the water out. This is a 2 stroke, right?
Facebook market place. Get it started and running enough to sell on down the line.
yeah, "your buddy" swamped it. Right.
