You need to meet my 76 Yamaha 80 enduro shes got a .222 in the head leaks fuel out it but she still starts im replacing the motor this winter to a modern 125cc or 90cc just dont know wat i wount to use its post to be the Frankenstein bike
@@Michaelangelokowski no i think youre a little slow and intoxicated 😂😂😂 think about it "bulletproof" - "proof". Meaning its secure FROM being bulletproof 😮
@@avogavoof course it would because they are the same exact bike made in the same factory. They just slap Honda, Suzuki, Kawasaki, or Yamaha on the side and it sells for $2,000-$3,000 versus $300-$400 with some random Chinese name on it.
It’s a Honda… they make the best motors. The most durable bullet proof. Not to mention super easy to work on. Honda engineering is amazing. Miss old school vtec
@@caboose69 I had my .357 in hand when he did it and it took all I had not to. I lived on a farm and it was a street bike that I used as a dirt bike. 1981 350 cc. My pond had dried up and I thought I would do some mudding and got it stuck. We were target practicing around there when he did it. A few weeks before another cousin that was also his cousin, a friend and me wanted to borrow his golf cart. He was older than us my about 15 years. We were about 15 making him around 30. But I got wired his golf cart with my friend and cousin and we went on a little morning jaunt. We even stopped to fill it with gas but that's where things went wrong. I paid for the gas and donuts while the friend pumped. The cart was a 50 cc Harley engine and our friend didn't put enough oil in it. We got way out in the boonies before the engine locked up. We got lucky and a family on four wheelers pulled us home but at some point it went from neutral to drive and trashed the belts too so I could kind of understand his animosity. He was the kind of petty asshole that may have done it anyway but revenge was his excuse.
Well, water shouldn’t make it into the oil from the exhaust unless something was already wrong. Now, if it was the intake, that’d be a different story because of the crank-case breather.
@@kaidwyermost engines have a decent amount of blow by(from combustion chamber pass the rings into the crankcase) that's the main reason why it has a crankcase breather.
If the valves are open the exhaust will go on top of the piston and water will leak down into the crank even with damn near perfect rings. At least a little water got into the oil.
The shit we did to CRF150’s for supermoto is criminal lmao My godsend of an engine mechanic managed to get one to consistently and reliably rev all the way to like 17-18k and made that thing an absolute ROCKETSHIP
For Sale: Excellent condition, well taken care of, always maintained, gently ridden by an experienced young child, never abused, never raced, garage kept, not a mudder, never snorkeled, washed after every ride, always used a wash plug, never had a hose full blast in the exhaust and water filled the air box so full it ran into the cylinder, never made RU-vid videos showing the durability after filling the combustion chamber with water, always torqued spark plug to the correct specs, will be a great bike for the next owner, I know what I have. Will not respond to “is this still available” nor will I respond to “is this the RU-vid bike that was filled with water” I take excellent care of my motorcycle. Open to trades of other motorcycles but only if they have a snorkel.
The exhaust valve was OPEN. So.... When you kick it... IT PUSHES ALL THE WATER OUT OF THE CYLINDER. Not the same as water ingestion. Water ingested into the intake will be attempted to be compressed by the engine. In adequate volumes, it WILL hydrolock an engine. But the throttle would need to be opened far enough to allow a large enough volume to enter the cylinder. Most water ingestion happens at idle. So the engine just dies due to lack of airflow. Little harm is done due to the low water volume and low engine speed.
Yeah i think the same, try spraying the water from the intake, i bet you get a different result 😂 And also that engine doesn't have a compression release mechanism
As an automotive mechanic that’s fucking wild!😂 I do love Honda engines. Had no idea they had a built in release to prevent hydro locking. Thanks for teaching me something new today!
@@suzysuzuki8865ahh, It did seem weird for Honda to install a feature to prevent hydro locking on a small bike like that. Your explanation makes way more sense from an engineering standpoint. Thanks!
@@ImOblivious yeah but that's why we have research, Google, manuals, manufacturer recommendations. Because reading about a risky thing is better than doing it.
Lived in Asia for a couple years and had a Honda Wave 110i. Riding in the monsoon season and hitting a body of water a bit too deep. Engine shuts off and I'm sure it's done. Take it to the next mechanic and all he does is clear out the water and it started right up. Amazing stuff!
Kudos for not cutting the video. Hate it when people think that cutting the video keeps attention, it doesn't. Even just 1 jump cut can often mean it's fake
Can confirm. Have an XR200 motor that has been fully submerged, lost half of it’s oil when a bolt came loose,and it still runs fine. The only thing I’ve ever done to it was replaced the spark plug. The oil has never been changed or topped off and it runs off of old gas from a can I fill once a year during the winter. Hondas are the Nokia phones of dirt bike motors.
We sank a mid '90s Yamaha phazer snowmobile in 60 ft of water for over 30 days in winter broke through the ice. Once we got it back on the ice and pulled it over a few times, it fired right up. The gauges were screwed and the seat was messed with all the water and ice that froze inside it. But other than that water doesn't kill an engine.
I have a 2005 Honda CRF100F and I went for a 15 minute ride one day on the road before I was gonna do an oil change on it. The ride went well but from the moment I started it I noticed it was chattering a louder than usual. When I got back I let it cool down and then I took the drain plug off, but only 1 single small tiny drop of oil came out and that was it (now would be a good time to mention it burns oil HORRIBLY.) I freaked out and refilled it with oil, went on another ride and it ran just fine. That happened about 3 years ago and it’s still running just fine to this day and hasn’t been rebuilt. Yes I plan on rebuilding the top and partially the bottom end very soon, it DEFINATELY deserves it. but that’s why I’ll never not buy a Honda.
I can’t for see rust being a thing unless it sat with water in cylinder, as long as it runs after and goes thru a heat cycle I would think all water would be gone from cylinder. Imo.
Right but if you run it after getting it out of the water, it'll push and cook the water out and the 50:1 applies a new coat of oil to the now clean surfaces. It would be bad to NOT run it after getting water in it.
I don’t know what compression release he is talking about but compression release valves are for reduced compression to kick or crank over faster to start a high compression engine. Even a C. R. only reduces compression temporarily until an engine can fire off. However during the compression and power strokes of an engine the valves are all closed therefore leaving no room for anything solid, liquid, or gaseous to escape therefore trapping it in the combustion chamber. Water being non-compressive in nature wouldn’t be able to compress and during the compression stroke would damage the engine if enough water was trapped potentially causing valve damage, head gasket failures, con rod failures or bending, piston cracking, ring failure, a cracked head or automatic head removal, head stud failure, spark plug thread failure. Some may be unlikely and you might get away with no damage but if the engine and exhaust are full of water, there will be no where for the water to go once the valves close locking whatever’s left inside. If you care about an engine simply pull it out of the water, remove the spark plug, remove the water from the intake, cylinder, and exhaust as best as possible, crank it over a couple times, and replace the spark plug to start it easily and safely.
If water only enters through the exhaust, that means that the cylinder(s) will only take in water if the exhaust valve is open. That would be during the exhaust stroke and once the engine is turned over, it should push nearly all the water out. I might be missing something though.
@Braapman_ You said an awful lot for not having a clue how the compression release works on this Honda. It does exactly what it's called = the engine doesn't (CAN'T) make "full compression" (let alone hydrolock) until it actually starts or "turns over faster than it can be kicked over", so it "can't and won't damage any of the parts you listed". This compression release holds one valve open "a tiny bit" (again) "until the engine turns fast enough to disengage the compression release". And just FYI, it's pretty much impossible to damage valves when they're "almost completely closed". Yes it will start sooner, easier if it's kicked over with the plug out first but this guy showed that it can be started without doing that...
I did this when I was little with my first dirt bike washing it and thought I killed it. My buddies dad just kicked it like ten times and then turned it on and kicked it and it fired right up and I had about 10 more years out of that engine
The engine is not on the compression stroke because the water is coming through the exhaust valve and into the cylinder and out the spark plug hole. So when the bike was kickstarted all the water exited the cylinder in the exhaust stroke. The engine would have hydrolocked if it the cylinder was filled with water at bdc on compression stroke. I am not an expert and interested in what other people say.
i also have no idea. but i guess if you try to kick start it and it feels locked up you could just pull the spark plug off and push the water out that way.
When i was a kid i had a buddy who was the most fearless person ive ever known to drown a bike. It didnt matter how deep the water was, he wouldnt even check first before barreling off into it. And surprisingly, a KX125 will run for a surprisingly long time completely submerged. If it drowned, wed drag it out, kick it over a few times and brap brap it was back running just like that.
Their car engines are solid too. Had a 97 civic that I never changed the oil on, sold it in 2012. Only ever topped up the oil never changed. Sold for parts due to body damage :( great car
@@PGP_TO no money at the time, car I bought for 1.2k so it was already pretty old by the time I got it. Didn't need topping up much and seemed happy enough. I was going to drive it into the ground since it basically only had scrap value at that point, just wouldn't die 😂 had other issues like electrical and rust so didn't want to put money into it
@@guser436 oil will pay for itself in the sense that it keeps your car going for a lot longer. Putting money into a car isn't always about "value" but can be about the utility it has in your life. Driving you around for a couple more weeks or months is definitely worth $20
Happens all the time in boats and jet skis. They sink, they capsize. Cracks or gasket failures can cause exhaust and intake manifolds to leak into cylinders. Even rain water under the right circumstances. If you try to crank it with water present it can hydrolock. You can damage starters, ring gears, bend valves and connecting rods. Can't compress a fluid. Get the water out, correct the issue, and run it. If engine ingests water while running, it can damage the engine. That's when you want to shut down right before it goes under.
I had a p90 Yamaha hydrolock in a creek. 2 smoker. It sheared the flywheel key just enough where the bike engine ran backwards 😂 we had hell of a time trying to ride a bike in reverse. Omg it was hilarious
They dont even sound bad running in reverse. Pretty cool fact aboout a 2 stroke. Ignition will be retarded though. Thats why when you sheared the woodruff key yours ran easily in reverse
Believe it or not, a lot of boat motors have a reverse cam in them so that they actually run backwards like the old 305 Chevy blocks Marine cam would make the engine run exactly backwards than a motor and a car... And since a 2-stroke off and has reed valves and stuff like that and not a cam it can run backwards and it's not that hard to do
Wait then how does the engine get the air fuel to ignite on top of the piston? I get it now it fires below the piston and it causes the piston to travel up the cylinder rather than how when a four stroke fires it pushes the piston down. I learned a lot today thank you!
THANK YOU! I'm so tired of hearing people say don't shut it off under water. And "water will get in through the exhaust." So what?!? Reality it probably wouldn't be able to get up that far unless left a really long time. I was thinking the wet plug might leave you hanging, but that bounced back quickly.
My old 85 ATC125 got swamped literally floating in an irrigation ditch for 15 min. Pulled it out choked it and it fired up after a little bit of cranking, bunch of white smoke but she ran and cleared out, got me home no prob! Miss that three-wheeler
Remind why I bought all Honda vehicles? Oh that’s right… 😂 one brother has a Ridge @ 200K miles NO issues, one brother has a Chevy @ 70K miles and a bad transmission. Lifters next. Dad’s on his second Ram @ 90K miles. Do the math 🤷♂️
Eventually it'll hydro lock. Let me ask what part do you think the snorkles helping. As of right now the snorkle just allows air to engine submerged or not your proven that point. Simply just getting lucky till you don't
@trashhousecycles actaully it can have you taken engine classes. When water goes into your exhaust the only places it's not going is to your oil. But till you bend a ring the water and oil will mix. Other than that you've got intake and exhaust valves therfore defeating the purpos3 of the snorckle. I'm telling ya your luck will run out. But at least it's a cheap bike
@@krichtainswanson1931 two stroke doesn't have valves or an oil system the same way a 4 stroke does, the oil is in the gas and flows through the moving parts before combustion to lubricate
@HammerSurgery yea but this dudes bike is 4 stroke. And your wrong about the valve. Intake and exhaust. They have to be there 2 stroke or not. And we all know about the differences between 2 stroke and 4.
I sunk an atv before. It started right up and a couple oil changes to get all the water out and it was fine. It worked perfectly for 10 years before I had a problem. There was corrosion where the ecu plugs into the wiring harness. Cleaned that up and it's still working.
My dad got a 1984 250cc honda quad like 20 years ago, he has had that thing under water and bouncing down cliffsides several times, it always rides. Kicking is easier to maintain than a battery power starter.
A compression release cam is the greatest thing since sliced bread. It lets you start your mower without the pull cord ripping itself out of your hand when you hit TDC on the compression stroke.
My friend and I were riding my crf 50 in my backyard, and my friend ended up in the pool with the bike. After we got it out of the pool and drained the water, it still ran fine for years after. Hondas are great little bikes!
Both of my sons have had Honda dirt bikes. Honda xr 80s,100s, crf 80, crf 100, and they have all been through hell and back. I have a 1990s cr 80 put up for my grandson in mint condition. Great bikes
If the engine stopped at TDC this would work. If it’s at BDC and the whole cylinder is full of water no compression release is going to let all that water out.
My Accord sucked up water last winter and started hydro locking while driving. I pushed the gas pedal all the way down and didn't let the car stop for about 5 miles. Car ran great after all the water got out.
My dad rode an XL 100CC off a bridge at our property (accidently) it stayed upside down in a river after bouncing off a tree for 1yr.. i dragged it out & had it running in around an hour.. old honda engines are just something else
Starting it will pump all of the water out. It's basically a pump... Though yeah, as mentioned, it's not great for the engine, because you will leave some water inside which will get evaporated and leave some mineral residues, those may damage the cylinder seals, but also slowly get flushed out by the gasflow and heat 👍
I had a mate who tried showing off by doing donuts when we went camping in 2011. We were camping 3m (10ft) above the river, the river had a cliff like drop. He got grip at the wrong time and shot off the cliff straight into the river. My other mate and I jumped down the embankment, I yanked the bike off the rider while my other mate pulled the rider up from under the water. His step dad had the bike running again in 45 minutes. 13 years later the bike is still being used on the farm 👌
I rode a Harley Super Glide as a daily driver for a couple years and there were more than a few times where it got drowned when I got caught in a storm and the front wheel hit standing water. It seemed like it was almost designed to cascade puddles right into the intake. Bumped the starter a couple times to clear the water and it always started right back up. Put 40k more miles on it after moving before I decided to put bigger cans on it and another 12 before selling it.
It becomes a problem if the engine ingests water during the intake stroke. Because the next stroke the engine tries to compress water, which causes bad things to happen. If your exhaust valve is open when you kick it over, it pushes the water out before it can hydrolock. That's why it works in this case. How do I know this? I was a Honda motorcycle mechanic for 4 years, and saw plenty of these smaller XR"s and CRF's ruined by going in the drink.
As long as the water doesn't dilute the oil too much, but even with water a few drops in the oil, some of it can be released as steam with the oil hits temp. Arm chair mechanics need to put down the keyboard and pickup a wrench. Great video.
I rebuilt this Honda GX200. It was completely locked up when I got it so I wondered why. Took the head off and it blew the valves through the piston. I wish I could post a picture on here because it was a glorious sight to behold
Nothing like washing the oil off your cylinder walls before you start it. I’m sure it has scarred rings and cylinder walls now. But he did prove his point.
I rolled into a bog with an old honda 3 wheeler years ago. Completely submerged. Saved it and myself. Thing still started after about 5 kicks. I miss that thing.
As someone who sells these and other brands for a living, I can tell you that this is a Honda for ya. I have customers with 90s models XR’s and CRF’s that have never had an oil change and they still run like new. When it comes to N/A low compression motors, Honda does it the best.
Filling the cylinder up with water when it isn't running isn't the issue that people are pointing out. Hydrolock is a real thing, and it can damage a motor. Sure, if you are idling in the water with an engine with that low of spinning mass, you may get away with it. But that doesn't mean you can't damage the motor if you ingest water.
I got a honda ATC that went though the ice one winter. It got left in the pond while we got my buddy warm and dry. Late spring when the water warmed up enough we sent him back out there with a hook and a rope and we winched it back onto shore. Cleaned the water out, fresh oil and gas and it fired right up.
This brings back memories of when we built an 8-foot high dirt ramp on the edge of a lake (with a friend's Bobcat) and then we took turns ramp-jumping a Honda ATC 110 into the water😁 We only jumped the girl's 3-wheeler that we knew I was going to rebuild afterwards and we also took turns with who the tow-starter (and ATC) was after each jump. We abused those Hondas beyond belief and the only one that failed to ride home was because it had a broken axle...
@@KCadbyRacing one of the most awesome stories I’ve read out of all the comments I’ve been getting 🤟. That’s what I hope all this makes more people want to go out and do instead of staying inside
I think the thing I was always told was not to let up on the gas while under water past the exhaust. I can't remember being around anyone that ever took that theory past that point without a snorkel kit.
I fooled a buddy thinking I drove through the water, it was 6’ deep. Told him to get a run and pull the front wheel up a bit so he doesn’t get soaked. He went straight in a disappeared. When he came up we pulled the bike out. We all had a piece of garage hose in our handlebars in case we needed to siphone gas. We used it to suck out the fuel and water. It fired up on the second kick.
my 150f was totally bulletproof absolute beast in reliability started up first crank literally every time ,and when it was cold it started up 2nd crank , waterlogged it atleast 20 times, i just changed the oil after and took the plug out and cranked it and boom start right up
All of my personal small engine equipment that I kept because of how reliable they are, generator, pressure washer, lawnmower and tractor had engines that were stuck from water in both the cylinder and crankcase with one common brand name. Honda. I’ve been doing this long enough to be able to tell what seized by the pull start. A little movement is rings rusted to the cylinder wall. Zero movement is the coil rusted to the magnet in the flywheel. Obviously both can be true but I’ll get it running because Honda engines are just built from better quality materials. Usually it’s the fault of the company that used the engines with their accessories like the air filter box that acts as a funnel for water like both my generator and pressure washer had.
I had one too. Looked like a mini bike with a clutchless 3 speed transmission. My throttle cable broke so I drove it around with one hand on the bars and one to pull the cable from the carburetor. Boy would my arm be sore afterward. Gear shift was stripped so I had a small vice grip for that. Had a lot of bikes since but never with the compression that thing had. Kickstart went through a cheap pair of Walmart shoes once and bruised my foot. Don't make them like that anymore.
Did the exact same thing to my dad's bike when I was around 7 or 8. He took the plug out on Monday morning, kicked it over, put the plug in, kicked it over some more. Stared at me, then went and got in the car and headed to work. 😂🤷♂️
That only works because your expelling the water. Under water you can't expell the water and the back pressure from the sealed exhaust will stall the engine. You'll Prob get it working again after, but it will stall UNDER water.
