I PUT Jet Fuel in my Orange County Chopper Motorcycle 

I worked as a helicopter technician on a french air base. I used to put Jet A in my VW 1.9 TDI (same flash point as diesel and waaaay cheaper as it is exempt of taxes). It cleans the injectors and pollutes way less so no problem passing the Motor Inspection. The only problem is that it is less oily than diesel, so the fuel pump is not properly lubricated and can deteriorate. I solved that mixing it with 2 stroke oil (about 2%).

This is more entertaining than an episode of OCC.

I always felt sorry for idiots that got ripped off by OC.

Jet fuel contamination is actually a major factor in engine failures in piston aircraft, particularly in light twins where fuelers are more likely to screw up and confuse them for turboprops. Jet fuel will absolutely ruin a piston engine, while something made for jet fuel actually might run (badly) on avgas.

OCC, making $80,000 bikes by taking $5000 in parts and charging $75,000 to assemble them.

Without even watching 5 minutes of this I know for a fact: - Methanol (racing alcohol fuel) requires a MUCH higher stoichiometry compared to gasoline. So simply putting it into a carbureted motor will never run properly. It will be massively lean. You cannot simply "jet up" either. You need a carburetor designed for alcohol. - AvGas is similar to racing fuel but is oxygenated to burn at high altitudes. It's high octane so it burns slower so it can be used in high compression engines. - "Jet fuel" is basically the purest form of kerosene/diesel/heating oil. So running that in an internal combustion engine designed for gasoline is nearly impossible. Also, simply increasing octane without making changes to take advantage of it (increase ignition timing, increasing compression ratio), is rather worthless.

It was cool to hear how that engine sound changed with different fuel types and that new engine looks so much better on that bike

I wish I was there to tell them that JetA/Jp5 is the same as diesel/F-76. It just has antifreeze additives.

People went crazy for those bikes. They were and still are nothing but a high priced TURD... what a waste of money.

Are you selling the old broken Evolution engine? I am looking for one to rebuild.

What this bike needs is a Bubble Engine! 😈

this is the bike we need to see going through the scrap yard shredder

Jet fuel is nothing like gas, it’s more comparable to diesel.

I like that I can actually watch this show with my kids. Nice good clean channel and entertainment

ive missed watching occ because it reminds me of my child hood. thank you for bringing back some great memories Edit: so sad to see an evo motor be wasted but yea that chopper needed way more power

Love this show! As for car building shows Texas Metal is awesome! No screaming and they show their whole process!

This is literally what every episode of OCC should have been. And thanks for not screaming at each other the whole time...lol.

While watching OCC I was always surprised at how often they ran into the same problems making a "new" bike. They never seemed to learn from those mistakes and always turned out (IMHO) garbage.

You guys have a very cool show and I will continue watching however with episodes like this I would appreciate seeing Data comparison tables. Remember, as an audience we see only a small portion of what you folks see during the testing. You can’t assume that we know what you know. Thank you

My dad and I used to run AV gas 100LL in our gtos. Used to pull up to airport and fill up 6 5 gallon cans. Funny, it was like 2.40 to 2.75 a gallon several yrs ago and that felt pricey back then..now it sounds dirt cheap! Our ponchos sure ran great on it and the best part..the smell...can't get enough of it! Like the smell of a 2 stroke, used to go to supercrosses yrs back when 2 strokes were in and would come home smelling like oil n gas PJ1!!!!!....man something about that smell.. So good!!!!! I used to put av gas in my lawn mower even, would also pop flames out the exhsust....beast lawn mode!!!!

OCC the official chopper brand of “hi, I’m an orthodontist”

I really hope the OCC guys will see this

A few years ago there was a guy that had an OCC chopper that he brought up to Schochs Harley Davidson in Stroudsburg, PA. One of the salesman said to the guy " Start it up Let's hear it" the guy replied " It don't even run ". Turns out he was an electrician that did some work for OCC and they gave him the bike in exchange for the money they owed him. Those bikes are for show only. Half of them are never ridden. The Harley dealer was bought out a couple years ago and is now Pocono Mountain Harley Davidson in Tannersville, PA. Ironically Rick Petco from OCC has a shop that was built in the new dealership. He does custom work for their customers when they purchase a bike from them. Now if you want to make that thing run take it to JD Cycles in Nazareth, PA. Dyno Dave is phenomenal with turning a bike.

These guys are geniuses especially Craig I wish I had a Craig next door for any mechanical issues lol

I'm all in on a whole channel that buys OCC bikes for 1/10th the original price and run them into the ground with 91 octane and simply running them to vegas. Subs can guess what mile marker it will fall apart.

Everybody is first until the page refreshed

Thank you from the UK 👍👍

That's nice but I have been using a small pellet of semi enriched plutonium-239 in my 1992 FXR Superglide and she has been running great for the past 27 years. I converted the combustion chamber over in 1995. My two cylinders and heads are solid lead. So far so good.

I was dead when Sean grabbed the left handle to twist the throttle. Edit: My apologies camera tricks when your chilling on the porcelain throne🚽🍩

The episode where Shawn learns that jet fuel is high grade kerosene

I hope you guys had good ventilation when running with the avgas, organic lead compounds are not good for your health.

I had a Honda 750 motorcycle with a custom built engine bored out to 950 and had a cam. It was a strong running engine. I used av gas in it almost exclusively. I never had any trouble with it and the av gas made it run sooo very good.

I worked in an airport. The fuel supplier, (Buckeye Pipelines) explained to me the jet fuel was basically diesel with a higher Sulphur content.

Now we need to get our hands on some rocket fuel next.

Looks like be great for winter on 50/50 mix keep your foot nice and warm

The best part of this is way better than OCC is yall are not SCREAMING @ Each other 😁 I like this channel just saw it & y'all are trying to figure a cheaper way to gain Horse Power and lower fuel price. I use to watch orange county choppers those 2 would like remind me of my dad & my oldest brother all ways disagreed on little to nothing while chewing each other's azzes out till where I'd get scared till one of them leave and that'll be my big brother it got so bad that my big brother moved out as a teenager to live with my grandmother my dad's mother but never did they punched one another that I know of lol but yep Sr and Jr didn't get along good while I was around except when they go bowling in a tournament so as a child remembered this I gain a whole lot of respect to myself when my first son came into this world I've learnt how to not have the same relationship that my dad and brother did my first son is a Jr I'm Sr he's 22 going on 23 I've just turned 56 we have a good relationship with each other. Not once in his life time under my roof and out from under me on his own had I ever had to give him a spanking 😁 we got along great as much as I hated the way I had to see how father & son didn't get along good at times but it was a learning experience for me. Thanks for the video you have a subscriber

As long as their screwing around with kerosene they should try running it on citronella. Then it will keep the bugs away.

jet Fuel is high purity Kerosene, can't see that being a good idea in reality.....;)

American chopper was an amazing show though, just to look how they work, someone I know always told me Choppers are show pieces just to stand there look pretty, and this video and the last one proved that point xD

I've run Grey Marine (GM) 6-110 diesel engine engines on an oil barge with kerosene and kerosene/diesel fuel mixtures. Except for some additional sparks coming out of the stacks they ran fine.

Senior built that chopper; he was having a senior day while buying cheap parts made by Daewoo!

I can't fathom spending 80k on any bike, let alone one with a stock evo! Some people have more dollars than sense I guess....

Ten your old me was the biggest OCC fan. I had the toys,shirts, even got the OCC pedal bike for Christmas. So i will give them credit for getting me into all things mechanical. So ill still show them love . Even if there stuff is muxh more for static display over performance

Exhaust flames on tie down strap, brilliant.

I used to mechanic for a amateur bike racer in the U.K , we used to mix standard pump fuel with avgas , it gives a better burn and runs cooler , important when you have a skimmed head , polished ports and all the other things to try and wring the neck of the bike for whatever you could get out of it

All the pilots watching this cringing just thinking about putting jet fuel in this gasoline engine? Or is it just me?

""The nectar of the gods"" I love it! 🤣 Which 2 stroke golden spectral mix and diesel fuel is the real choice of the gods! Lol

nice show thanks guys.

It's like the pimp my ride bullcrap they pulled, looks cool but mechanically just garbage.

You make me pumped for this riding season.

Wow what a bonus the Revtek motor and Baker transmission

AVGAS has LEAD (LL = LowLead) ! Dont breathe the exhaust fumes!😳

This is why I watch your channel, Sean! I love it! Y'all are always doing some next-level crazy stuff on here! Love it! haha

its so awesome how fast your channel has grown this past year.

I hadn't seen my bud in years. When I traveled to see him, both of us now married with kids, apparently he wanted to impress me and put aviation fuel in his old 54 pan chopper. (very cool bike in the day). It blew out oil from every seal and gasket. Much more than usually LOL. After a couple hours of hymin and hawin, troubleshooting, he fessed up changed the fuel and spent the weekend riding like back in the day.

Jet A is basically something between #1 diesel and kerosene. I know a guy who accidentally filled up with diesel in his twin cam and cracked the top off both pistons. Don't exactly know why but it did.

Awesome vid,thanks for taking the time and expense to do this,I always preferred Jesse James,West Coast Choppers,surprised the old evo hung on so long,obviously at the time built to look at more than ride,cheers,best wishes frm Auckland,New Zealand,🛵🚲🛴👍🧨🙂😉

We use Avgas 100LL in our 2 stroke dirtbikes as a source of non-ethanol fuel, since we can't really buy non-ethanol fuel at the pump except in racegas (VP Racing) formulation and the AvGas at $5 a gallon is 1/2 the price. It runs absolutely fine, though I'm always thinking of driving one state over to get lower octane non-ethanol fuel to mix since higher octane fuels don't burn as well as lower octane fuels when the engine doesn't need the higher octane due to compression reasons.

Be careful on that death trap 😂

Try the 2 cycle Ttufuel. It's high Octane and a mix for the cylinder Lubrication for the rings. After those runs might be a good idea to change the Oil.

7:20 is like when you watched your dad talk to another dad about something you dont understand and you just stand there listening

My 61st birthday is today and I get a Bikes and Beards video to celebrate. Also, a bible verse, thank you Bikes and Beards.

It's a testament to the Evo engine that it didn't blow the fvck up immediately. Those things not only saved the MoCo, they were pretty well bulletproof. Had an Evo powered bike for 13 years, and that engine never let me down once.

Your "Chopper Motorcycle" ??? Yeah, thanks. That Chopper part had me Confused 😂

"Jet fuel" is high grade diesel fuel, NOT AvGas !!!

Did any of the Tuttle’s chime in in the comment section? An OCC chopper is still a better value than one of Hunter’s paintings! ROFL

50 / 50 putting out good looking flames

I remember how awkward it was when the original owner asked them to make the “Corporal Punishment” seat. Perhaps the most homoerotic moment in a long series of highly homoerotic moments for OCC.

As a pilot, the very *thought* of trying to run jet fuel in a piston engine (or gasoline in a turbine) makes me very uncomfortable. The NTSB database is full of wrong-fuel fatal aviation accidents. Smart pilots *always* either fuel their own aircraft or supervise the person doing it for them. I recently read one report where Jet-A was loaded into an older aircraft with turbocharged piston engines by a line fueler who, mistakenly, thought the aircraft had turbines. For quite some time, the FAA has required that fuel inlets have different throat sizes and that fuel nozzles have matching spouts for the correct fuel to prevent this sort of thing. The typical accident profile has the airplane taxiing and beginning takeoff on the good fuel and then abruptly losing power on takeoff as it is exhausted which is a nightmare scenario with low survivability.

Wait there is gonna be a Harbor freight motorcycle video That sounds sick

Liked watching this , my hope is He irons out all this Bikes foybles an makes it better.

I was going to suggest throwing a little premix in when I heard those 'dry cylinders.' That was before the insanely low compression figures. Wonder what it was beforehand... Can't believe after all that money and 'custom work' that they would run a STOCK h.p. motor.. Why?!?! I used to make my own homebrew race gas by mixing toluene with some 93. You can get it at a store like Sherwin Williams. There is a chart floating around online somewhere with the ratios on it. This is only useful if you can tune/ advance the timing to make use of it and obviously it doesn't apply to everything in that sense. Otherwise it'll just keep it from pinging. In the end its cheaper than something like CAM2 or VP, but not as high in octane. You can get around 100 octane or so with the toluene/ super mix. Love the old Wurth cabinet! They make some AWESOME products. Nice pics from the scope as well. Thanks for sharing this.👍👍😁

i put racing fuel and my push lawn mower. i could hear the rpms picking way up i was so excited. then bam connecting rod went through the side lol

During the compression stroke of the engine (due to physical laws) the temperature of the combustion mixture increases. Due to a certain octane number, the gasoline does not burn spontaneously until the spark plug ignites the mixture. Diesel engines have a fundamental different injection system. Jet fuel is chemically close to diesel and will run well in diesel engines, but really not well in a gasoline engine.

RAZORBLADES ... ha ha ha h Danger is the New Cool !! lolol

It would be interesting to see the afr on all these runs 😃

I know a guy that bought a OCC chopper the welds was shit and even the engine wasn't what they said it was they are frauds

Jet fuel is basically kerosene... this won’t end well. 😂

Yummm avgas god I love the smell of lead in the morning. Guys have been using that stuff in two strokes for a long time

AvGas is basically high grade diesel. I'm speaking of jet fuel you can put jp8 in a f-18 hornet and then also fill up your Humvee

They went in to kill the EVO but EVOs never say die.

"So we dumped kerosene in there" wasn't as good of a title, eh? Also, the number of folks in this thread that don't understand that Octane is the measurement of the RESISTANCE to burning is too high.

I enjoy these videos. I’ve always wanted a bike. Maybe one day I’ll get one. You pick the best verses. I enjoy that most!! Come lord Jesus, be our guest in our hearts.

Have you ever trayed laquar thinner..I did on a big block 442 dodge...wow

it didn't work becouse alcohol is for drinking trust me on this

" yea there is deffinatly more " even if you pulled another 20 hp out of it, it still will not be as fast as the persons ego rideing it

Avgas LL100 has a higher anti-knock power than gas normally on the market. For this reason it's possible to stand a higher compression ratio and getting as a result more power. Burning LL100 without any modification offers little help

I used to watch this show back when, and I did think it was odd that a show about custom buildings things, used so many parts made elsewhere. I think 25% of any episode, was them making the fuel tank, the only real major custom part.

Jet fuel is essentially kerosene, IIRC, and alcohol makes an engine run really really lean, you have to give it a lot of fuel. Burt Munroe found out the hard way at Bonneville, burned several pistons (or so I read).

I know nothing about bikes but I enjoyed the show because the bikes looked so cool to me. Here in the UK we just don't see choppers anywhere. I always thought the bikes looked flimsy though like the weren't engineered to a high quality especially the fancy decor. Now I am shocked that the devalued so much. They must of made massive bucks during the craze...lol

I used to get AVGAS from our refueler for my car, it cleaned the carburetor nicely.

So whats wrong with an EVO motor? I've got one on my chopper. If 65hp cant get the job done on a 600 pd bike or so then there is a problem. I mean just how fast are you wanting to go on a bike?

Wondering if there was valve damage after this experiment

I like how 60hrsprs can still make Nice pops and bangs

They where motorcycle stars I liked watching it o well

That exhaust Brandon put on looked so bad ass, way better looking then that little stump of the original

man sees fire. "wow!!!! look at that! look at that!"

I think at 60-odd HP, the engine just doesn't have the compression for big gains, hence not being able to handle its alcohol.😛 And: why didn't you throw any chairs or garbage cans around?

I love all the backhanded OCC comments.

Yeah that's aftermarket,moded, dope
