So what you're saying is. The fuel pressure regulator failed,too much pressure in the rail and in turn to much fuel being injected in to the cylinders while cranking caused hydrolic lock. Big was lift with excessive fuel in the cylinders. The fuel leaks past the piston rings and fills the sump... how many time did this have to happen to end up with over 8 extra ltrs in the sump.!. I'm shocked that the customer was able to change the spark plugs but NOT check oil level.. I agree with the other's saying you should have done a couple of oil changes and surprised you didn't mention suggesting it. At least the customer was happy it was finally running again 👍😊
Not a mechanic but I believe the FPR rubber diaphragm gets a tear and then fuel can flow straight through to the vacuum hose to whichever intake port it is connected to. The unwanted fuel flow would happen by gravity, with the engine shut off.
Blackbird needs to be up to running temp, switch off and then let sit for 2-3 mins before checking oil. My fire blade is the same and a real pain in the ass. You’ll never get it spot but if you check oil level before you warm it up and it’s on highest dipstick mark, it will be overfilled. I really don’t know why Honda don’t use a sight glass like every other bike manufacturer and make life simple
Absolutely love this sort of stuff. Can relate to everything you did there. Logical, down-to-earth, very competent and super-efficient. Would trust you with my bike, any day of the week. Thanks for sharing and take care.
Well done Steve, hope you dont get a cold after this work outside. Not nice to work in that conditions... Hope to see you in near future again on the channel ! - The old Biker -
Hi Steve I had the same problem with my black bird. It was the fuel regulator valve. And the reason why it wouldn’t start it was hydro locking. I’m sure this has the same issue. 😜.
I had one of the first production Blackbirds back in 2016. At 20 years old, it was still on its original exhaust system. They are a well built machine. The problem with this one I would tend to suggest over fuelling causing it to lock up. PS: I thoroughly enjoy watching your videos.
I'm sure I could smell the petrol from here Steve 😁 great work mate watching all the hassle to remove the fairings etc bet your glad when it's a naked bike your working on .!! Great stuff think you'll need to dig out the thermals for a few weeks .👍👍
You should drop the oil again after warming it up and maybe a run around the block just to clear the engine out of any remaining fuel in the crankcases pal
I've seen a few Blackbirds squirt like that in my time, usually caused by a stiff petcock, they tend to get left in the on position and if they fail you get the same result...
Only a few minutes in, and my carb’d Fireblade did this.. The carb float needles had ethanol fuel corroded/gunged up and had jammed place, filling the engine with the contents of the fuel tank 🤢 I stripped the carbs which were horrific.. I have changed the oil, but I’m going to do it again before I use and sell it this year. I have 6 other bikes to keep me busy, and I need space 🤯😂 Good video 👍🏼 Edit. I now remove ethanol from the fuel in the bikes (& add Stabil), especially stored over winter. 4 of my 7 bikes are carb’d and they suffer even more with ethanol fuel issues
I’m at 1:35 guessing. I think it’s the gear portion sensor got a broken wire. 2nd guess for engine is that the owner took the cam chain tensioner partially off and extended a little, then cranked the bolts down forcing more tension on the chain.
How does the fuel regulator valve failing allow that much fuel into the sump? I would have assumed it would have just affected the running of the bike due to incorrect fuel pressure?
The FPR has a rubber diaphragm inside; the intake vacuum changes the regulated fuel pressure so that the pressure differential between the intake and the injector remains constant. If the diaphragm gets a pinhole or tear, fuel can be drawn straight into the vacuum hose and into the intake. That would make it run very rich on that cylinder but the bigger problem is that there is now a direct path for fuel to flow from the tank to a cylinder.
Don't forget the kneepads Steve ! Crank case full of fuel - somethings up with the fuel management system - injection or carbs which could have bent a conrod etc. as you and others have said.
Great video thanks. I'm curious how the fuel would fill up the engine. Is the bad regulator allowing fuel to bleed through the vacuum line back into the engine?
Did you not get a true oil level reading has its leaning down wards on the piece of wood also would you of been better squirting some oil in the bores to lubricate the rings from the petrol contamination ?
Don't understand How unregulated fuel press. will still get past the injectors. Did this happen just sitting there or while riding? Looks like almost the entire tank went in the engine. Wonder if the injectors now need replaced.
The two 12mm fuel line banjo bolt washers should have been replaced as they are a one time use item. The nut should have been tightened to 16-20 NM. If you have a toque wrench use it, if you don't have one, buy one. You diagnosed the fuel pressure regulator as defective (you did not test the fuel pressure ??) You did not replace it. What up with this?
Hydrolock is a condition that occurs when a device that compresses petrol, like an internal combustion engine, is prevented from doing so due to too much liquid in the engine.
you earned your money with that one steve

Best motorcycle mechanic channel on UA-cam Steve!
Have you not seen superbike surgery..?

My Er5 has the exact same problem albeit with a leaky float valve in the carb. Perfect timing! Great job mate!
Lovely job mate. No messing about. 👍👍

Wow..when that fuel flew out the plug holes!! ....awesome video once again steve.brilliant.
Well done Steve, hope you dont get a cold after this work outside. Not nice to work in that conditions...
Hope to see you in near future again on the channel !
- The old Biker -
Nice and direct Steve, unlike your competition😅
No fuel tap on the injected bird, only the early carbed birds, I had one of each and the carb was a bugger to start when left for several weeks.
Very nice diagnosis. What made you think to check the oil level first?
Hi Steve I had the same problem with my black bird. It was the fuel regulator valve. And the reason why it wouldn’t start it was hydro locking. I’m sure this has the same issue. 😜.
Your best video yet. Props to you and the camera woman for filming in the cold.
Could the neutral light just be the bulb?

Great work Steve and no swearing lol
Great video, good fix and I guessing happy customer. I only ever had blackbirds with carburetors, so didn't guess the issue.
Well that bike was happy to see you Steve! Great video, and a great tip about a common fault.
You should drop the oil again after warming it up and maybe a run around the block just to clear the engine out of any remaining fuel in the crankcases pal
That'll sort itself out as soon as the engine is warmed up, there is no need to sell the customer 2 oil changes
Happy newyear Steve, great job as usual!! Learning a lot of the motorcycle technics , thanks!! Greatings from Holland..(and happy newyear cameralady).
i remember servicing an er 5 for a lad an i had the same thing a face full petrol it stings a bit lol
🎉 Happy new year to you and the 'camera lady'. Always enjoy watching your uploads..
Another brilliant video steve, keep them coming mate. Happy new year.
Brilliant as always pal. Learning a lot watching your videos. Keep em coming 👌

Blooming enjoyed that, cheers!
beatifull machine mate congrats
Because the stand is on wooden block ,oil level will be slightly over ? Initial reading😮
Very useful video, great info if I ever get another SBB 😁
Excellent video. Did you get the neutral light issue sorted? What was it?
Good work.
Top job, great video! 👍
You never see Blackbirds here in the US. Nice bike.

I came to say this too, kneepads thermals and a winter coat!
Never seen so much fluid in a engine 😮
Great video once again cheers. By any chance have you a video replacing a timing chain on a blackbird?
I don't know whether Steve has, but Superbike Surgery has a timing chain replacement video on his channel. Another great mechanic worth a watch.
Cheers, I'll have a look!
Brilliant 👌 what a cracking bike aswell
nice clean engine inside now :)
excellent video with great content thanks.
Great video thanks. I'm curious how the fuel would fill up the engine. Is the bad regulator allowing fuel to bleed through the vacuum line back into the engine?
Pretty much
Good to know. Cheers 👍
Lovely bike
great job Steve. tons of patience. Hayabusa is much better designed for ease of access.
Did you not get a true oil level reading has its leaning down wards on the piece of wood also would you of been better squirting some oil in the bores to lubricate the rings from the petrol contamination ?
But clicked
Leaking fuel tap hydra lock engine
Extreme Bore wash 😂🤣
Bad petcock let fuel flow into the cabs, maybe a stuck float to the air box and engine and filled the engine locking it up.
Don't understand How unregulated fuel press. will still get past the injectors.
Did this happen just sitting there or while riding?
Looks like almost the entire tank went in the engine.
Wonder if the injectors now need replaced.
Hydro locked?

What up with this?
Fuel tap leaking .
It doesnt have a fuel tap. Its an injected model
Why would a faulty component flood the engine to that degree?
yup she's flooded , fuel tap or a stuck needle
i bet you make her sing again
Was the neutral light a red (green) herring?
Ah….destroyed by the petrol contamination….Dedication on show here out in the cold…. 👍
Good job. Well done BUT please use a kneeler or wear kneepads. Take it from an old guy who didn't !!
👍
When customer had the tank off recently to change the plugs he has inadvertently disturbed something to cause this........
Not likely
Lol...needs some more oil i reckon...🤣
I would say it is hydro locked
I would say hydro-locked 😮
How do I contact you to book you in? I've got a 2015 triple 675r with a stripped thread on a plug,
I believe we have already spoken 👍
Hydrolocked ?
Hydrolock is a condition that occurs when a device that compresses petrol, like an internal combustion engine, is prevented from doing so due to too much liquid in the engine.
I reckon before watching it is a seized engine😋
