Your compression is only about 50% of what diesel needs to run with power. That's why a diesel runs with out a sparkplug. It requires different conditions. I was surprised it ran that well while idling. Great video! 👍
Thanks for watching, I’m glad you enjoyed 👍
so you're saying it needs to be done on a 500 2 stroke next? 🤔
@@DaCodesMan That wouldn't have much more if any more compression, so no
@@DaCodesMan No
@@cane2253 no bitch boy
Most diesels were 2 stroke in the past but with a much higher compression ratio and stronger engine, of course. I love the sound they make. 6/71, 12/71, 3/53, etc
Blowers injection is nice. But I'd rather be blown.
Don't sleep on the commer knocker. Great engine :)
YEA, THOSE SUPERCHARGED 2STROKE DIESELS ARE COOL, SCARY WHEN THE RACK STICKS OPEN!
Detroit Diesels have Hi Pressure injection timed just BTDC .. It's called compression ignition with high pressure fuel injection ..
Completely different principal.
That beautiful two-stroke sound give me goosebumps every time I hear it
Sounds like my childhood
Kinda makes my heart pitter-patter. Weird...
Same
Decades ago I worked for an art handling company in Los Angeles. I rode my 1964 Lambretta (2-stroke) to work every day. I had my own parking spot & kept an extra gas can at work in case I needed to fill up, as there's no gas gauge on the Lambretta. One day a co-worker filled up one of our diesel trucks with gas. Once the truck made it back to our lot my "superior/supervisor" Steve bought some gas cans and drained the fuel out of the truck. He didn't have enough cans, so took mine & drained the diesel/gas mix in to my can. I went looking for my can & found out Steve took it. He told me where to find it, but din NOT tell me he drained diesel into it. I filled up before leaving work & blew a head gasket about 1/2 way home. Had to tear down the engine & new top end.
Next day I was 10 minutes late for work, as my Lambretta was my only vehicle & I had to a get ride from co-worker. The same dude responsible for blowing my head gasket then wrote me up for being late! However, he didn't write up the co-worker who drove me, or the other employees who arrived after us!! When I asked why he's only writing me up, his answer was that he "relies on me more". The next day he was late for work, due to a flat tire (which had nothing to do with me.) ~Instant karma. I asked him if he's going to write himself up for being late & quit that job shortly after.
Long story short. Don't put diesel in a 2-stroke.
Nobody cares
This is the true definition on the more you fuck around the more you find out. Good content keep it up👍
Pretty fun experiment. I didn't actually expect that it would run. I would think that the timing would need to be advanced at the very least to get something more out of it. Then again, diesle has some force when it pops, I dunno. Maybe an instant bent rod? I wonder what would happen if you go the thing up to 13 or 15:1 compression and a glow plug?
Some old tractor engines--you'd start them on gasoline then once they warmed up you'd switch them to kerosene or "coal oil". They had oil sump lubrication. During the gasoline shortage in 1973, I started my lawn mower on gasoline then switched over to kerosene. Did the same with a VW Bug then but ran it easy because might burn hole in pistons.
diesel fuel is apparently 1:100 fuel to oil ratio I would like to have seen you added 2 cycle to the diesel so you wouldnt have to worry about lack of lubrication inside the engine but what I think is there is a ratio and a curve where a little diesel fuel added to the gas may give an advantage you should try one tank with 1/8 diesel 1/4 diesel and 1/2 diesel see how performance varies and add the equivelent 2 cycle to get 32:1 which is what I believe what your bike is supposed to run at
The whole point was to see how the bike ran on just diesel, not with just a little added to the tank. It was just an experiment but I agree with you I think a mixture like the one you mentioned would have ran better
Diesel has plenty of lubricant properties
Why? What makes this worth it? Some things don't need to be tested
@@brownjamie7008 your question is: why?
My question is: why tf not! 😂
If you add just 2% of diesel fuel to gasoline it brings down the octane 1 notch. So I don't see how diesel would help but who am I 🤷♂️🤣
I had a 99' Yz125 that I had a bunch of work done to. I had just rebuilt the thing with a new 1st 2nd an 3rd gears, fresh top end, all new seals. The bike was ported/polished matched, carbon reeds, ignition, fmf pipe w/shorty. The bike rode really well, had mcr suspension under it. I miss the thing all the time, sold it to buy a new Yz250f. I like the 250 a lot and honestly wish I didn't need to sell the 2 stroke. This bike reminds me a lot of the one I had though! Cheers p.s just goes to show these things will run on anything. Great little motors.
I had a 2000 YZ125 with a RPM motorsports 139cc kit. It was a really strong 125.
Install a constant glow plug..and try it again..?
@@gentrynewsom2080 glow plugs are only for starting a diesel they turn off once it’s running
0:37 that was perfect
Interesting, I believe 2 things where happening.
1 Lots of smoke because not enough compression to really fully burn the diesel. Diesel engines are usually 17 to 22 to 1 .
Second, running lean because the diesel is so thick it doesn't flow through the small jets in the carb.
It wasn’t running the best that’s for sure
17 to 22 to 1 . (17-22:1?)
You must mean the air/fuel ratio. (Stoichiometric ratio). Gas is about 14:1, so if he needs more air or less fuel to get 17:1, he should be running rich now. The viscosity is a factor too, but I don't know how much. The smoke does indicate a very rich mixture, with raw diesel probably blowing out of the exhaust port,---and probably soaked into his silencer packing. lol
@@EarthSurferUSA he means compression ratio not air fuel ratio. Diesel engines have a higher compression ratio than gas engines
I have a jetless lectron carb, half tempted to try it on my gas gas to see what happens...although my maintenance has been so poor as of late it runs like the diesel with 2t gas 😆
@@EarthSurferUSA no he’s correct on compression ratio being at least 17:1 to 22:1. As for AFR 14.6:1 is Stoich but a diesel engine runs from 17-70:1 AFR depending on where it’s at in the load map. Diesels use a Cetane rating vs gasoline using Octane. With a diesel you want ignition to happen as soon as possible since it’s direct injected whereas a gas engine needs knock resistance. Sorry for the long reply 😅
I was expecting it to foul out and possibly not start. Of course I'll be 60 soon and I still think in terms of convental ignition.
I didn’t think it would start or run, I was honestly surprised myself. Smoked like I’ve never seen before though. Thanks for watching!
That bike is old not sure what your point is. It has a conventional spark plug like any other bike.
The fact that it ran makes me want to bump up the compression, (a lot), maybe advance the ignition, and make sure I get the jetting good, (research it and try). It sounded on the gasoline that the bike has a worn out top end, low on compression,---and diesel can take a lot more compression than gas. With some research and work, it might run pretty good.
@@EarthSurferUSA If I'm correct two strokes run better with low compression and the best way to add power is by adding a turbo.
@@wsbill14224a turbo in a 2-stroke won't happen, as a turbo requires pressure-fed oiling to lube its shaft and to provide cooling. A belt-driven supercharger OTOH may work, as it can have a separate oiling with splash-lube instead of pressure-fed.
Sounds pretty crispy for Diesel and starts surprisingly well.
A friend and I pulled an old 2 stroke Lambretta scooter from a scrap metal bin that was to be melted and recycled.
Mixed some Kerosene with gas (not as bad as straight up Diesel) and made that thing run for a whole day before it quitted on us.
Those were the times ! 😁👍
K1 runs better in heavy equipment in the winter then Diesel does lot of guys switch over or add it in during the colder months!
@@tammyforbes2101 oh ? Never knew ! Thanks for the tip. 🙂👍
you should have put 2 stroke oil in the diesel, nice video man!
I thought about it but truly wanted to see what straight diesel would do! Maybe next time lol
Should of but it didn't matter too too much because diesel acts as a lubricant too
Diesel is an oil
Was thinking that too
Diesel is a little rich
My dad had a 4 stroke cub cadet weed eater that of course ran straight gas. One day he accidentally put diesel in the tank and either he had it already warmed up or had one hell of a time starting it but either way it ran perfectly fine, maybe just a slight bit sluggish. Otherwise there was no obvious sign it had diese in it. Well he kept using diesel after that because he thought it ran better. Although every time I used it I found it very difficult to cold start. But it would eventually.
Definitely much harder to start, the bike ran terrible on diesel and I don’t recommend it. Stick to pre mix but it was a fun experiment!
Done the same with my bandit 600 , ran lumpy and it smoked for a good couple oh week , even with petrol in it but it eventually cleared ,
I peed in my Bultaco 250 and it wouldn't start
@@Crosshatch1212 I did personally do it to our lawn mower and it randomly let out a huge puff of smoke at one point and after I switched back to gas it smoked so badly it was unreal. It was like as if you through 50 smoke grenades around the tractor and it never came back from it. Had to get rid of it. I’m still not sure if it was directly related to the diesel or not. But the timing was spot on.
@@fredmitchel1236 must not piss high octane.
Did the engine actually seize up? If not, then you just need to clean the spark plug to get it going again. You may also need to clean out the carburetor.
you are the reason the internet exists and I fucking love it.
I love how you sprayed diesel all over the jug and ground like a complete savage, then pointed at the I did that sticker with all the dilligaf in the world 😂
Why would you ruin a perfectly good bike
👌
@@anthonymartinez9005 cause it's gonna ruin itself eventually
people rebuild 2 strokes all the time
it's just part of riding that type of bike
I doubt it did any real damage anyways
@@Kerosene682 "Blown Up" means that the Spark Plug refused to fire. I would bet that no damage was done to the engine at all. I'm with your comment on this!
i'm just afraid it's gonna wreck the crank case and combustion chamber because there is no lubricant
Diesel is a lubricant
@@powerslide000 But it's not enough, if it's lubricating enough then most diesel engine won't need oil and oil pump. It's only as good as a frying oil level of lubrication. Therefore you'd still need to add premixes/2-stroke motor oil
Your compression on a good top end will be about 180 psi. Diesel needs about 300-400 psi. The diesel will also mix with your pil in the bottom end of your motor. Striping the lubrication from the moving parts and eating some seals. It will plug up the spark arrestor as well. Flush your crankcase and neutralize it for acidity. Then replace the crank oil. Replace your spark plug and netralize the carb and the cylinder. P.s. dont do that again.. you can find fuel neutralizer at any chainsaw store. If you really want to kill your bike, put in alcohol and dont re jet the carb. It will sit and burn up the piston while warping the head and you wont be able to shut it off.
"oil in your crankcase" ???
It's a 2 stroke.
Do you know why you put oil in the fuel of a 2 stroke?
Maybe watch some videos on how a 2 stroke engine works (small engines, not the giant V4 diesel units that power "hook and ladder trucks" and such).
Once you understand that, along with reed valves, etc. then you can make comments that make sense. 😊
You know exactly what’s going to happen 😂
Try aviation fuel/diesel/lub oil mix and re jet to get a better fuel to air ratio. In the UK winter, buses use a aviation fuel/ diesel mix to prevent low temperature waxing of the diesel. Evaporation of fuel through the carb will lower its temperature and 'freeze' the diesel in the carb.
For a carb., the jet's needed to be resized, maybe the metering rod had to be re-located &/or replaced w/ a fatter rod(?) & the air screw needed resetting. I agree w/ a previous commenter, show the tear down & analysis of the engine. You're going to have to go through a lot of experimentation w/ jet's, rod & air screw to make this worth while. Since you're imitating the smoke from a forest fire, maybe switch to a thinner base & head gaskets to up the compression a bit but that won't be similar to a 15.0:1 static c/r. The main feature w/ Diesel is that it's much more difficult to light off from an electrical spark then what gas does. Thanks for the video.
The carb on a 2 stroke dirt bike has reeds and not jetted/metered like a normal 4 stroke carb.
@@neilgelinas9926 I thought the reeds were supposed to function as a 'one-way' air flow valve? I've seen 2-stroke carbs & they have similar jets & rod. An Electron carb doesn't have jets, everything is controlled by the rod if my pea-brain serves me. The bodies are different between a 2 & 4 stroke.
@carmiethompson2676 lectron carbs have one jet with a metering rod and a dial tune on it some what like a air/fuel screw but adjusted by "clicks" a 2 stroke is jetted like a 4 stroke carb accept it has a air screw as turning it out makes it leaner where a 4 stroke carb has a fuel screw and turning it out makes it richer
from what i understand, you'll need to be closer to around 16-1 compression ratio to be able to use diesel reasonably. i would suggest watching temps, and if it doesnt get too hot, see about increasing compression.
The biggest problem is the detonation becouse you get a spark at ~25-32° tdc and the diesel fuel ignites to early ... it can run but extremely ineficient also the compression is to low .
First thing I noticed was it was rather dark outside. I wondered: "is this morning or evening?" I skipped ahead and realized it was morning cuz it got lighter as things went on...so Kyle's out there @ 5:30 am pissing off the neighbors.....so this test doesn't count. 😄
I still have a 2 stroke street bike I bought new in 1985. It's almost mint. It's a Yamaha RZ500.
Friend of mine swapped the forks off something modern, like a gsx600 and had the braking and suspension of cutting edge technology with a triple two smoke under him. Not sure where it is now but a great project
@@jeffreystroman2811 My brother had a Kawasaki 2 stoke triple.
If it is mint (or otherwise), it is a gold mine.
What a unique way to say: "I am an idiot!"
Pretty cool to see that when deisel is added to a yamaha 125 you get a 70s era hodaka powerband
Ran a sedan with a V6 with 95% diesel once. We were stranded and that’s all we had. Ran great, smoked a little. Oh, there was gas in the line and because the engine was hot, it fine. Drained the tank and flushed the lines, before we filled it with gas.
I think it's going to run fine but smoky until the plug fouls from the excess oil. Of course you did show a little preview of it running.
I love the way a two-stroke sounds and smells it is great
I've rebuilt engines, 4 stroke and 2 stroke, and I'd especially like to know exactly what happened to the cylinder walls and pistons/rings. Did it lean out and score? Was it enough lubrication without thr 2 stroke oil? I happen to know a two stroke is very dependent on that oil because it sucks in through the bottom of engine (crankcase) and ultimately lubricates everything in the stroke process. Critical... Are all tjr gaskets okay? Crankcase or head gasket okay? I think you could make an excellent update with s full examination of what happened in that motor even if you have to get an experienced 2stroke mechanic to lay out thr details. There are a lot of people that would love to know, see, study this because not many people are willing to experiment in this way 😉
It "BLEW UP."
This clown didn't blow anything up...... As the cylinder/piston heated up and expanded the UNLUBRICATED rings the cylinder walls scored and the engine seized.
Dump some machine oil through the plug port, rock the bike back and forth in gear until the piston moves, and light the bitch up with clean fuel........
It won't run as well as before but it will run.......
There should be a follow-up video of a top-end rebuild to show the damage.
Would have had to do a tear down first, none of the results would be viable
I'm sure you have a fresh wiseco top end laying around before you decided to give this a go 😂. New sub from me man. I enjoyed that.
Thanks man, I’m glad you enjoyed. You won’t be disappointed… I’ve got some more crazy stuff in the works!
@@kylecorbett sweet look forward to watching!
Mate topped up Petrol into half a tank of diesel by accident, He drained it when he got home, I took it off his hands and run it in my old Ford fiesta, It run well on a 50/50 mix. No mods, just a old carburetted 4 stroke/smoke.
On my 50cc Honda scooter you can put 3/4 GAS and 1/4 Diesel mixed into the tank and the torque is increasing, this mixture is daily working fine.
You on your bike chilling might be the coolest thing I've ever seen. You hopping on it and your 2 stroke going BBBBBBBBBBBBBBZZZZzzzzbzzzzz.
Saw that coming! Diesel is meant for way more compression. Hope the video at least pays for a rebuild!
I wish!
@@kylecorbett He is right, and you can modify the head for more compression. You might be surprised the rebuild may only cost you about $150.00.
If the cylinder plating is not worn out, pretty much just a piston/ring kit and top end gasket kit. Take some scotch brite pad to the plating, if the plating is good to remove the old tarnish, clean it up, and put it together. I just spray some WD40 on the piston and cylinder walls a bit for some lube for the initial start up, and to help seat the ring a bit faster. If you plating is worn out "US Chrome" in Wisconsin has replated cylinders for me, and do a excellent job. It has been a while, but the last time I had it done was about $150.00 also. This is where you are very happy,---you are not rebuilding a 4-stroke.
I have found though summers in Michigan of riding a lot and racing, a crank lasts about 3 seasons, so measure the rod slop, (research it, and the owners manual may have it in there), while you have the cylinder off. And of course, a good practice if having the crank rebuilt, is putting all new bearings and seals in the cases.tranny. I am anal about maintenance though,--but in 10 years of racing, I never had a mechanical failure. :)
@@EarthSurferUSAIt can make more compression but that will also stress-out the crank.
Im pretty sure desiel fuel needs a higher compression to auto ignite as i believe they use glow plugs to get started but dont need spark to keep going.
probably bog down and choke at first but if the plug is hot enough and ignition strong it'll probably run until she blows . hell of a video idea man hahaha. You got my sub 👍
Thanks man I appreciate it, I’ll do a teardown video to check out the damage!
this video is actually really good way to show people what pinging sounds like.
40 years ago, my neighbor mixed fuel for his Rupp Nitro L/C at 32:1, but he mixed his 2 stoke oil, 1 qt of Castrol 2 stroke oil, to 1 qt diesel. Thing always ran out hard.
I can imagine!
"hear what it looks like" nice good one let me just add that to my senses
7:18 look at the bottom of the engine, it has some blowout on its downside..its blowing out some exhaust fumes on that spot ^^
That’s completely normal
With the gas in the beginning, I think you need to rebuild the top end. It runs like an enduro. Low on compression.
You can make any engine run on almost anything as long as the fuel air mix is correct for the vaporization and density of the fuel. You can even run diesels on straight alcohol, but the pump has to be built to withstand the lack of lubrication.
Good point
Sucks Nitro. Max the Blower last of the V8s.
you could run it on coal dust or finely blended charcoal.
@@grisher111 You could, but Union Pacific found that engines don't last long with such an abrasive fuel
@@grisher111 Indeed! During WWII, Germany was using coal dust as the fuel for their pulse-jet engines (V1 "buzz bomb"). The large gas turbine engines in electric power generation stations are often run on coal dust...
any hydrocarbon can be made to run in just about any internal combustion engine.
I once put diesel in my Ducati by accident. One mile later she stopped. I called my neighbour, he came out with an empty can and one of fresh petrol and spanners to drain the carbs and tank. It took a while to do but she has been ok since . Did your 2 stroke run on pre-mix petrol or oil injection?
Looks like a good way to get home in case of emergency.
Shouldn’t do any real damage but might smoke for a little while. I’d be interested in seeing the spark plug afterwards.
Maybe I’ll make a follow up video of the bike… take the head off and show piston and spark plug..
Man, you are crazy I give you that, just hope it doesn't carbon up your piston rings. However, there're a lot of 2 stroke diesel engines out there though.
Would be awesome to see a tear down video. I think the comments mentioning lack of lubrication is what killed it.
A lot of people have mentioned a tear down video, I’ll have to do one
@@kylecorbett I did not watch the vid much. But if it stalled, probably a fouled plug, (pull it after it stalled. Is it wet?). I think you need to replace the piston and ring, (if the plating is OK), anyway, but I doubt you had a lubrication issue. My bet is you will find the piston and cylinder covered with oil. But I never ran diesel before, so you tell us. :)
Diesel is a lubricant...
@@kylecorbett
I always have my bike idling at 5000 rpms
It's the lack of octane. There's already way too much oil in diesel, hence the smoke. Try lighting diesel on fire with a cigarette lighter. It needs to be hot to burn. Versus petrol which ignites if you look at it the wrong way.
Old tractors had change overs after it warmed up you could switch to diesel but not good power and they were five to one compression.But a two stroke is very sensitive on jetting
i will give reply later on this info called TVO Tractor Vapour Oil and parriffin washing issues needed frequent oil changes
$3000 FIRM, no low ballers I know what I got. Runs great, just needs a carb cleaning.
🤣
Diesel fuel is super low octane. It isn't rated that way, but it does tend to explode instead of burn.
Considering you changed nothing but fuels It ran better than I would have thought.Larger main jet hotter plug some 2t oil it might even work.
Curious to know if it took out the crank bearing or the piston stuck to the cylinder.
I’d prefer to see a donation ,to some one who can’t afford a bike..
@@badlyniceness2315and the other way around for someone who can
The diesel looks like the stuff that turned the turtles into Nijas. lol
Diesel is just like really thin oil, i used to run my diesel car on cooking oil with no problems whatsoever 👍
Is it still feeding 2 stroke oil in via a pump.Or are you running on just running on diesel?
Fun fact… You could run diesel in a gasoline engine, but you cannot run gasoline in a diesel engine. It seems counterintuitive, but it’s true.
You most certainly can run a diesel on petrol especially if it’s an old mechanical indirect injection diesel
@@LR90_200TDI Problem is the ignition temperature is higher for petrol (flash point lower ) so the cylinder temp may not be high enough to ignite petrol . Diesel genny at work got filled with petrol and refused to run , would nearly fire but not run (direct injection ) , also petrol would soon wreck pump as no lubrication
@@LR90_200TDI Thats interesting the recycle frech fries chip oil brigade use about 5% gasoline and cooking oil treated with methanol to get cetane ratio to 55 and run old direct injector type diesels on that fuel Same engines run Kero no problems but might wear out fuel pumps faster from lack of lubrications for fuel pump . modern inline diesel best left alone to costly to fix
With diesel Compression ignites it adding a spark plug is going to cause some rough uncontrollable combustion as we found out through your video. Cheers
Its 40 octane and mostly oil vs 90 octane and 1% oil.
Your plug is probably fouled but the rest should be fine. Just put normal 2stroke back in it and give it a hiding.
Diesel doesnt have a Octane rating...

Reminds me of that Project Farm channel where he throws all kinds of mixes in lawnmower engines to destroy myths.
Thanks for watching. I’ve always been curious what would happen so I went ahead and tried it!
I'm surprised it ran at all! Even more surprised it blew up! I was expecting the high oil content to protect the mechanicals. Great vid! Learned something today.
I’m shocked it even ran!
It's not close to the oil content as 32:1, I run 40:1 VP 2T and that's pretty dang lean... Ktms are 60:1, diesel is the equivalent to 100:1 which is 100 parts oil to 1 part fuel, which also has cetane rather than octane. I'm surprised it had the compression and sprayed a fine enough mist of fuel to combust.
Diesels still rely on oil for the valves and everything, just like a 4 stroke or gas powered car.. if a Diesel relied solely on it's fuel for lubrication to prevent grenading like a 2 stroke, it wouldn't work either.. in Canada during the winters I run kerosene in my heavy equipment, it's like a thin less oily Diesel, similar to fuel in helicopters/jet engines.. works great in winter, will over heat in summer if you forget to drain it.
Jells up in cold. I used kerosene also instead of the diesel.
@@yamahakid450f 29,000 psi high pressure pump on common diesel is lubricated only by diesel seems to me is must be a pretty good lubricant " were do you get this 100:1 figure from ? "
Gretta is done sewing your Voodoo doll together.
Least we can do is give you a thumbs up, as you did blow your bike up for us, poor bike! 👍🏼
Jetting the carb is going to be needed as well as milling the head for more compression.
Frankly, I think the fact that you had some two stroke mix and then added diesel, still enabled the petrol component to initiate the spark and the moment the diesel got hot, it too ignited easier why a spark.
However, the pure diesel showed its reluctance to combust BUT when it is hot enough it does.
Don't try that the other way round i.e DON'T try and run a diiesel engine on petrol; that will destroy the diesel engine as it will introduce very high physical stresses by combusting far too early.
That's not the problem with running a diesel on petrol. It's the lack of lubrication through the injection equipment that destroys it.
I'm quite sure gasoline is combusting later ( than diesel ), leading to higher physical stresses(A more violent detonation from the more fuel present when the fuel is finally ignited).
The less ignition delay the better.
Fun fact: I ran a 95' YZ80 for 2-3 years with nothing more than 87 pump gas.. With intentions of blowing it up to do a big bore kit aaand - Never happened! Bike ran Great the whole time I owned it
Are you saying you ran a 2 stroke with no extra 2 stroke lubrication and if so hiw many miles roughly example 10000 miles
Pretty shocked it ran, as diesel doesn't ignite that easily. CDI ignition for the win I guess 😆
I’m right there with you I was shocked lol
It's the high compression ratio that caused it to run
Accidentally filled my road legal yz250 with diesel, it wouldn't tick over but ran at high revs, it got me home though😃
What a great video btw! I am surprised it ran. I think the lack of 2 stroke oil was the only problem though - it would have been interesting to see how it would of ran with a diesel 2 stroke mix!
Thanks for watching! A lot of people have said that so I might have to give it a try!
try it on an air cooled 2 stroke and take the head gasket of and replace it with a very thin bead of ultra copper silicone or if you can find one a super thin gasket and tune your carb super lean after you get it started and i bet it runs like a champ. for a while
A higher heat range spark plug would help.
30 years ago we did it every day on old small engine bikes , runs good never blow no 2 stroke engin with diesel or dilute diesel and gas. I am surprised how easy stalling, only way to stop the engine off was to cover intake with my hand.
You know you have no compression when you can start your bike in crocs🤣
It’s a 125, they have no compression to begin with 🤣🤣
@@kylecorbett Ik I’m fw ya I gotta steel sole can start my kx250 in my slip ons🤣
I start my rm250 with only 15 hours with crocks
Try 50/60 mix then 40/60 it will have less snap but torque will be at the slower rims. I know from experience. Got some deisle put in a tank that I didn't know about. Didn't hurt any thing
Ain't no way dominator is better than 927
I’ve personally not run 927 but have ran everything else out there. Dominator is superior to everything I’ve tried which is why I’ve been using it for 10+ years now. I might have to pick some 927 up to compare.
Smells great too, nothing quite like that old-school MX castor oil smell on a cool morning to remind me of my childhood in the '70s~'90s

Nope 😂😂

Believe it would never run right again any way.
@@bigdaddybruce757 Surprisingly after a new plug it runs great!
Im surprised that it ran at all. Cool experiment dude!
The desire of been in RUclips is too powerful.
One time i had absolutely no 2 stroke oil. I was at a friends house many miles from home. We mixed 10w30 with gas and the 1977 rm100 ran like a champ all the way home about 20 miles
I ran 30W motor oil mixed with gas in weed eaters and chain saws for years and never had any failures. I mixed it to the correct ratio for them but used 30W non detergent motor oil instead of 2 stroke oil. I noticed zero difference in performance and everything started right up and sounded perfect, every time. Never tried it with a bigger 2 stroke engine but it sure worked perfect in the small engines for a decade. Got the 30w in bulk for other equipment and it was cheaper/easier to use it for the 2 strokes lol. I figured it would work fine in a pinch in a dirt bike and sounds like I was right at least with that bike anyways. I couldn’t believe how well that ended up working out but now I use premium 2 stroke oils and fuel like your supposed to 😂. Man if you have some gas laying around in a can for the lawn mower and 30w or 10w30 motor oil your definitely gripping it and ripping it!!! I only used the motor oil/gas mix because of a guy a used to work for in his 70’s that swore by 30w motor oil and gasoline for two strokes and it’s all he ever used and none of his stuff blew up on me and worked mint 😂 I doubt it did any harm to the RM100 only running it 20 miles, but like I said I strictly used detergent free motor oil like the older guy I worked for did. I was pretty skeptical of it for awhile and always expected whatever I was running to grenade at any time but it never happened. It even smelled like a worn out 4 stroke but it worked.
So the trick is like hey its in motion and not static. 2 stroke oil suppose to blend and stay blended with fuel but alwYz good to give the old snowmobile a good shake if its not oill injected whoch went away decades ago on sleds. Regular motor oil will settle and somewhat separate especially heavier oils like strait weight 30. Thing is lubercarikn is , slip and slide. 4 stroke oil and gas im sure must leave more residue behind? However i have turn many a 2 strokes down with rings cooked with 2 stroke oil all behind them in ths ring grooves so rings could no longer float as they should. Alwayz good ro run good synthetic 2 st oil in a machine value that u want to last. They are getting a much harder workout than a weed eater and much more time to rebuild them. All my sledz oil injected and i still mix 100 to one in the tank for insurance and never fouled a plug
@@charleslentz1673 Absolutely and I always ran premium fuel and 2 stroke oil mix in ALL of my dirt bikes, snowmobiles, quads Etc for those reasons my whole life to be clear. I’ve never even tried 30w/gas mix in anything other then small 2 stroke engines and happened to see your comment/story about you doing it successfully to make it home. I was assuming you took it easy and limped it home the 20 miles as I probably wouldn’t want to ring it out too much and pull higher RPM with the wrong mix and I only used 30w and gas mix in weed eaters and chain saws/small 2T engines only and like I said before even in those I still basically expected some kind of failure but after a good 10 years everything still ran mint. I upgraded to better equipment and started to use the right oils in the fuel when I did that and was no longer using a $99 dollar featherweight Walmart weed eater and poulan chainsaw that where basically throw aways so it’s pretty impressive that the cheap junk lasted so long on motor oil/gas mix.
@@OFFROAD-REVOLUTION well the thing is i was in a bind. My 77 RM100 got me away from thenplace i hated most, being home with the disfuction. Being hard working poor white trash i would use the train tracks to fo see some friends. In a bind and fingers crossed it worked. One horse town that didnt have anhas station a lifetime ago in Wisconsin, i was 13. That 77 RM100 was surely one of the best bikes i ever owned, the old honda elsniors where great to. Just like my current xr250r, bulletproof unlike all this crap now a days with pancakes for pistons. I have road this XR pinned at 70mph for hours on the highways and been on many trips. Incredible bike, they called it the super enduro 96-04. I used to ride that RM in the snow in Wisconsin before i got a junker sled. I would take like 6” peices of old motorcycle chain and bailing wire them about every 6-8 inches, she cut some groves
@@charleslentz1673 exactly what I used to do growing up, I rode every single day because of the freedom it gave me to get away from the house and see my friends. I rode to all of my friends houses as a kid and spent all my free time out riding or just at friend’s house hanging out so I get that to a degree and I’ve never heard too many bad things about the RM100’s and there used to be a few around the area when I was a kid that people rode the heck out of!
Amazing how much time some people have, in California working full-time with the traffic you can't even do one errand
It might have worked if you could hook up a blower to it.
I'm building an air-box with a 7" 3000 CFM ebay fan.
I will control the boost by controlling the speed of the fan.
It's going to smoke like crazy. And have not much power and likely foul a plug. We used to shut our old snowmobiles down on diesel to stink up the exhaust to discourage mice from moving in over summer.
I did this in 1977 on my Honda but I was running trick fuel 110 octane premium gas and diesel. It made my two stroke run like a bat out of hell! You’ll need to bring a spark plug wrench to clean it off but it does work👍
I honestly didn’t think it would work, I was pleasantly surprised!
Seems to run like a half-dead (low compression) diesel. Fun project.
i love hearing what things look like.
That was hard to watch . Don’t get me wrong very very entertaining but I was having a panic attack for you lol 😂
Wow that’s a clean 2001, iconic look
So on a 1998 yz 125 you can run a 1998 cr125 piston and it increases compression. I learned this from a Yamaha factory team back in 1998 that actually ran Cr125 pistons in their race bikes. On to the subject of diesel in bikes. I ran a 50/50 mix of gas and diesel in a four stroke KTM RFS engine for years just to see the results. Many fouled plugs was the only bad outcome. The bike actually ran great until I rode on single track in the woods and the plugs fouled. But riding it hard, the Carbon build up was non existent in the exhaust. I figured it would be gummed up after a couple of rides but it was almost like the exhaust carried it out and even the spark arrestor was spotless. I have yet to explain the out come. I tried it again in a Honda four trax 300, the atv stated much easier until the spark plug got around 40 hours on it. The idle was much smoother and throttle response was insane. I do work in the petroleum industry and tinker around with different mixtures of fuels for kicks and giggles. So I tried adding lubricity (which is a type of of detergent added to diesel) and that was the kicker. Every machine I had ran much better with lubricity added to gasoline. They run like silk. I could imagine anything with emissions would be gummed up from running lubricity. But adding a little diesel I can confirm will add longevity to your outdoor machinery. You will go through more dork plugs but they are cheaper than buying more engines and machinery.
thanks
So did it put a hole in the piston or break the rings with all the extra compression? 💚💛❤️
I did that with a Ryan weed trimmer when I was about 15 I found it ran pretty good with a little premix maybe 10% .
My kid did this with his kx85 and it ran for a good hour and then started knocking because the lack of lubrication took out the connecting rod bearings.
Sweetest sound I ever heard was a 78 international paystar with a 2 stroke Detroit Diesel engine. They sounded different than every other truck on the highway
i think if you tune the carb to use half as much fuel to air ratio it wwopuld run great
I think that's enough probably should run 2-stroke mix in it I really hope you didn't do damage to the engine.😊
Lol smokin out the garbage
Sharing some love with the family.
I add 2 stroke oil to my diesel to combat the ultra low sulfer in my Cummins. Wouldn't put diesel in my Kx's. Good video
Thanks bro
Thanks for watching bro. I will have to try the 2 cycle in my powerstroke to see what happens.
No don't put 2 cycle in your power stroke. You can prematurely plug the DPF filter
@@scottw2157 02 04.5 cummins Pre DEF no cats straight pipes muffler only been doing it for 20 yrs. On my excavator also. Lubricates the injection pumps and upper cylinders. Screw that DEF racket. Complete nightmare.
@@scottw2157 But yeah your completely correct if you have a newer diesel fuel system I would recommend not doing it. Sell it buy a older 5.9 or 7.3 those will last forever..
That’s good enough for a pinch in an apocalypse with no fuel just diesel left with 2 stroke of course..
My 2stroke bike with the aluminum bore ran sweet with diesel, but the 2stroke with the cast iron bore seized when it got hot 😮 I thought it smelt a bit like burning plastic or something synthetic.
interesting what cc was the alu head and what cc was the cast iron head
