Good evening everyone, I'm new to the forum so please forgive me if I have posted this in the wrong section or it has already been discussed.

I have an 08 zx14 with 9500 miles that I bought last year with 4200 on the clock. Here's my issue. A couple weeks ago I brought the bike out for a quick spin, got to my destination with no issue. Later that night I went for a 50 mile ride with the fellas and began to spell coolant on the way there. Reached the destination checked for leak and found about 5 drops on the ground where I parked. Could no locate the source. Not paying too much attention to it we headed home. I opened her up to about 145 to catch up to the lead rider and when I slowed down, the bike gave off a violent vibration throughout. I immediately Pulled her over at a rest stop and sent to give her a look over. Saw a minor leak of what smelled like coolant but looked like my oil(royal purple full synth). Could not locate the leak so I decided to start her up and head home slowly. I got about 30 feet and heard the infamous "metal bang". I hit the break and shut her off immediately And got a tow home.

A couple days later, I drained the oil looking for metal shavings and found nothing. Please note, the oil drained seemed considerably less than the required 4.5qt. I refilled the oil and started her up. I initially heard 1 metal bang and then nothing else. Instead the whole bike vibrates, even on idle and increases as I throttle up. Had a couple mechanics come take a listen and one said spun bearing the other was not sure but doubts it's a spin bearing.

As of now we have removed the clutch basket and all looks fine. Plugs and could replaced and nothing. The next step is to open up the case unless one of you great folk on the forum have any suggestions. I took a video of how she sounds after the oil change maybe this will help. I wanna thank you all in advance for any help or advice you may have. Sorry for any typos.

Here's the link

Im not a mechanic but that does not sound good. I would not run it anymore and bring it somewhere for a motor tear down. I am guessing but sounds like its skipping or running on two or three cylinders. Maybe a spun bearing or blown head gasket.

I appreciate it. The only time it's started was for this video. Yea that's the next step. I'll keep u guys posted

I ran my busa on 2 cylinders when I had a connection issue withe Bazzaz. never noticed anything unusual about the sound or even the performance in a low speed test run. It really sounds pretty normal unless you are listeniing for something wrong. Yeah, I'd say it's missing a cylinder.

could be that when you checked it, you smelled coolant which had overflown from the overflow tube and you saw oil. It was leaking both?

I'm guessing you didn't check the oil level before operating--no insult, I do that pretty often. If you could see the oil in the sight glass, even if it's low, I doubt you ran into oil starvation. You obviously have a leak though. Check the valve cover gasket. You'll see oil running down LH side of motor if it is severe enough and you will need to look under the rubber blanket that they use to conceal this very common problem with the gen1. I had the leak. Saw one 14 that had drpps on/under it. Very fixable but I fear you may have a bigger problem with that missing cylinder.

Crank = Vibration. This is a live and learn scenario. The moment it leaked, tow it home. It takes seconds to destroy the engine, not a ride home was began to eat parts, expensive parts. The bike is about to match what a runner is worth vs. rebuilding the engine. You are at a crossroads of your generic throwaway bike. Unless you can do the work, cha-ching!

Sorry to see/hear. Sucks man cause no matter what it's gonna cost you. If you wrench at least that's something.

Agreed this is serious. If you've heard big clanks something big happened. IME normally spun bearing is more of a knock (like hammer against an iron block sound) than the sounds I'm hearing.

You could start with some basics before pulling the engine. Checking the clutch area was a good idea. Remove the valve cover and check your timing chain and cam sprocket alignments and tensioner. Remove spark plugs will allow you to rotate the engine. Go to HF, or if you have a mechanic friend, get one of the remote cameras to peer into your cylinders. IF at that point you're not seeing anything probably need to go into the engine.

If you get into finding problems you're probably better off just buying a used engine than rebuilding it. Open your filter and see what's in it. If you're engines not full of shavings it might not be past the point of repairing.

I wouldn't run it again until the issue is found.

Hey guys and thanks for your speedy input. ROOK, you are 100% correct as I didn't check my oil level before pulling her out. A mistake I will never make again. And I'm not sure if it was leaking both. All I know is that I touched the few drops that hit the floor and it was purple Royal purple oil. The texture didn't feel like oil tho.

In foruntate to have a ton of mechanic friends and they all seem to say something different. Only time will tell. VIC THING, that is the next step. But may I ask, what is HF? Yea I was considering the used engine route but the engines have been few and far between. Guess people are still building T-Rexa. I looked at the filter and nothing. No shavings anywhere. The weather is gonna suck up here in New York this weekend; so hopefully we can get Aaliyah if diagnostics done.

Thanks again guys.

I got a bad feeling you have a spun bearing or a partially thrown rod. Good luck and please keep us posted.

I didn't want to say it right away but was also thinking possible oil mixed with coolant ....since you indicated it smelled of coolant but looked like oil. I was hoping it was an oil leak accompanied by a small coolant overflow. So if you touched it and it didn't feel slippery enough to be oil and you smelled it and it smelled like coolant and you looked at it and it looked like Royal Purple....sounds like internal oil leak. Oil's getting into the cooling system.

So, there's these two cavemen traversing the tundra and...

Lots of oil in the cooling system, I could see that causing a small overflow even if it didn't cause an overheat (you didn't mention seeing the temp go to 6 bars or the overheat code flash on the meter). If this was the scenario, I would expect a few warning signs before the situation became critical. 1)Oil level/pressure drops way low--definitely check engine light came on LH side of dash. You might not see it in the heat of the moment if you were going fast. 2)high engine temp--you might have noticed the engine temp bars go to the top but this again could go unnoticed if you were focussed on riding. 3) Coolant overflows---surely you would not have missed the overflow icon flashing on the meter. If you had none of these warnings, sounds like you overflowed the cooling sytem because the fluid capacity was far exceeded but not overheated. It could have been a rapid inflow of oil to the cooling system and you did not see the check engine light come on from low oil before the oil overflowed the cooling system which was functioning normally. I'd take the cap off and check the radiator filler neck for Royal Purple.

Hey made bell yea that's what I'm thinking. Rook, nah no overheat, no lights on the panel. fI flickered for a short second.

Yes sir, sounds fuckered to me. Being that it's missing, and you see oil/coolant with a bad vibration, Id check the front of the engine case for a hole.

No holes or even a crack in the case @nastynotch

HF = Harbor Freight. I'm pretty sure they have a few names, maybe Northern Tool in CA or other parts of hte US. They have a fairly inespensive video/remote camera probe thing. I was thinking of this or something like it just to peer into the cylinders http://www.harborfreight.com/catalogsearch/result?q=camera

OH--BTW, the Warning light is on the LH side but there is also an oil light on the RH side. Both are the top lights.
From my video I made a few years back, looks like both the warning light and the oil come on when you switch the key on. Warning light goes out after a few seconds. Oil light should go out pretty quickly after the engine starts.

Good evening all.... No real updates. I picked up a used motor and swapped it out. When the weather worsens I will definitely have my mechanic crack open the motor so see how much damage I did. Thank you guys for all of your assistance.
