2007 ZX-6R Coolant/Water leaking from exhaust

I purchased a salvaged 2007 ZX6-R to try and work on and try and fix. I ran into some mechanical issues, every time I try to start the bike it shoots coolant out of the exhaust. I tried to diagnose the problem but I can’t get the error code number to show on the dash. If anyone has any ideas as to what it may be I would really appreciate it. I think it’s a head gasket but not sure. Thanks for the help!!

Condensation? or rain collection?

Are you sure it is coolant?

how long have you run the bike and what does the temp gauge do when you do have it running?

radiator coolant level full?

recovery tank coolant level full?

woohoo we are having fun now
Stupid people say stupid things on the internet, so be wary of who those people are. If you solicit advice on the internet, just keep in mind 99% of what you'll receive is not based on fact or science-and likely atleast 95% of it is based on bullshit and bravado regurgitated from some other schlub who also did not experience any of what they claim and are also full of shit. If you don't like my bluntness- too bad. I am not here to please you, so move along, your approval is not desired nor is it needed. So before opening your pie hole and adding more stupidity, perhaps sit back, listen, absorb and learn something. You know that saying, it is better to remain silent and thought a fool than to open your mouth and remove all doubt!

The bike wont turn on it just cranks but won't start. When i put the bike in the on position the fuel pump turns on so i don't think that is the problem. The radiator coolant level is low just below the minimum line on overflow reservoir bottle. i uploaded a video of it on youtube not sure if this is allowed or not but i will include the video address.

You wonít get a code to tell you if your head gasket is blown! Or any other reason you would have coolant entering the exhaust flow...

I just watched the video....yikes! I see an engine tear-down in your future....

So from the research I have been doing i think I'm going to need a new head gasket because of the coolant leaking into the exhaust and I'm pretty sure I need to find a company that can check my carburetor because i found some fuel in the air box and from the post i have been seeing online that usually means there is a problem with the float and needle. Also thanks for the info on the bike not having a code for head gasket lol I"m still new to this so any information is welcomed

Just remember- if there are carburetors there are 4 of them!

But your bike should have throttle bodies and be fuel injected. So no carbs! Meaning no floats or needles....

Did you ever figure out how the water was getting into the wrong place?

Well when i changed out the oil there was gas in it and when i took off the exhaust headers water came out :/ my assumption is my piston rings need to be replaced which from what i have been seeing people just replace their engine.

That doesnít make sense to me. The water either came from a bad head gasket, or from a crack/break in the metal structure of the engine cases. Youíre going to need to disassemble the engine enough to know if it is rebuildable, but you are correct: it tends to be cheaper to buy a running used engine than to professionally rebuild a bad one.

Is there any chance that the bike was stored outside and the water you saw coming out of the exhaust was from rain accumulation? I still canít imagine how rain could get into the exhaust headers, though... lím reaching here...

Ya i do believe the water must be from some sort of flooding because it did not have any coolant mixed in with it and i stalked the previous owner and it was in an area that is known for floods. What confused me in that when i drained the oil all i could smell was gas and after doing the compression test i saw a lot of posts that suggested it would be the piston rings. I found an engine that is an 07 with 7k miles just need to save the cash to buy it and then swap it out.
