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%).

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.

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

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.

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

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

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

This is more entertaining than an episode of OCC.

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

What this bike needs is a Bubble Engine! 😈

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!!!!

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

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.

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.

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.

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

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

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

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

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

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

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

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

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.

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

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

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

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.....;)

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

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.

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🚽🍩

I really hope the OCC guys will see this

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.

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.

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

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....

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.

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.

Everybody is first until the page refreshed

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

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

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

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

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.

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

Jet A is simply super-refined diesel. It burns really clean so if you run it through your diesel-burning engine it'll run very clean, but less oily, so you don't want to do that all the time. Diesel is designed to lubricate parts in your intake. You put that in a gas engine and you're gonna F that thing up royally. AV-Gas is about 120+ octane, and burns super hot in your gas piston engine and is great for keeping your innards clean if you only burn a couple gallons per tank mix w/ reg. unleaded every once in a while. it will scorch your rings if you run it straight for too long. Also you need to adjust your timing, because it doesn't burn like 87/90 gasoline. With Methanol- you can't just pump that through your engine and expect it to behave like gasoline. It's not even close to the same.

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

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

Something I think most people get wrong about OCC bikes is that they were built for SHOW and not necessarily to be ridden. They were designed to sit and look purdy from a distance of about 10ft.

The AVGAS is concerning. It's not going to make more power just through octane. The octane gets more power because the engine can be run at a higher compression ratio (why sports cars want 91 octane, and aircraft try to maximize power to weight ratio). BUT--most AVGAS is leaded (Pb) gas. You guys are likely breathing in lead fumes in that tiny dyno trailer...

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

You make me pumped for this riding season.

I was a jet engine mech in military. Unlike some think, jet-fuel isn't anymore than çleaner kerosene, or deasil. Like unrefined gas. IT will mess up your engine if it isn't reeked and restructured to use jet fuel. You must tweak the fuel mix and or your motor. Go ahead, put straight jet fuel, or aviation fuel in your car or bike while stock. You will gum up , burn up and trash the works. A mechanics nightmare. Alcohol straight , if you don't melt the works, you may blow it. Try experimenting with a mix of clean bonny-light oil with everclear that has been strained. Then you have a chance on a good fuel. Be sure to use goo upper parts that can withstand abuse and heat. Or you may as well pour plain kerosene down the throat and get the gumming up over fast. But don't disrespect an old Harley or Indian v-twin, sacrilege ! Your stuff, have fun.

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.

"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

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

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

"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.

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.

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

I didn't think jet fuel would even burn in a gasoline combustion engine

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

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

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

Be careful on that death trap 😂

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.

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

I'm a army (Gulf War)veteran and would love one of those bikes, I still own a 2004 Harley sportster 883. I'm sad since you just chunk them, can you donate to a good cause. lol God Bless, I've been watching you guys for years. Though I can only grow a gooo Teee. I'm jealous. Be safe my brothers. You guys rock.

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.

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,🛵🚲🛴👍🧨🙂😉

Demonstrating that more “motorcycle” people know SFA about engines and how they work. Refined Jet A-1 otherwise known as refined diesel in a gasoline burning engine? Dummies.

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.👍👍😁

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

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

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

That "LL" in avgas actually mean "Low Lead". Breathing exhaust in closed space from this is not the best thing for you (or anyone else)

Fun Fact: Diesel, Jet fuel, Jet A-Fuel, Kerosene (outdoor camping lamps and stoves) and rocket fuel (RP-1) are all one family of fuels

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

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

""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

Thank you from the UK 👍👍

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

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).

Exhaust flames on tie down strap, brilliant.

Try mixing Toluene with Gasoline (50% Toluene, 50% Premium Gasoline). This will give a significant boost in horse power and may be a little less expensive than jet fuel. I like your show. Keep up the great work. 😃 Daniel in WA State.

I'm at the beginning and I'm guessing this is some sort of joke because jet fuel is kerosene. Aviation gas for piston engine airplanes is the real deal though.

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

Fun fact! 99.9% of military tactical vehicles in the US run on Mogass/JP8 and can easily run on JP5/Jet fuel. The only issue is fouling up the glow plugs.

Question : with all those spikes and saw blades sticking out, what does your insurance say when you are involved in an accident with physical or material damage they can argue is a consequence of these spikes ?

Used to work at an FBO. I'd pull my bike onto the tarmac and throw 100LL in it all the time. Smells awesome, runs more efficiently, better for your engine, and it doesn't contain ethanol do your seals don't get rotted. Used to have guys buy it all the time for their snowblowers in the winter because it's way better than gas.

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?

This was pretty obvious (the outcome) before they did it. "Jet fuel" is kero (kerosene.) Many say "No, because you aren't allowed to just put kero in a plane..." That is because jet fuel is kero with so many additives to disperse water/stop freezing etc etc. But it is (base) kero. But there are jets and jets. When they hang them off planes, (and to most civilians) they are called jets. The industry that fixes them, and when they are used in the military, they are called gas turbines. The LM2500 gas turbine is used on planes (for example, 4 x LM2500 on a Jumbo). But they are also used for power generation plants etc. The Navy (my Navy, Australian) use them to propel ships. So an Anzac class FFH uses an LM2500 to push around 4,000 tons of ship. On the ships, they run them on deso (diesel fuel), not kero. A GT will run on almost anything that burns. On planes, kero is the best compromise between performance/fire risk. On ships, deso is better. Similar power output, but also common fuel for diesel generator/propulsion engines. The ships DO carry AVCAT jet fuel (kero) for the helo. They CAN (and DO) burn AVCAT in the GT occasionally if they have helo fuel coming up to use by date. These engines create 25,000 hp, mostly running on kero. So, run a petrol engine on kero, lower volatility. Wheras AVGAS is just higher octane petrol (aviation gasoline). Any normal car/bike will run on that, but no gain unless you change comp ratio/timing to exploit it's anti detonation properties. For example, I have a Dolomite Sprint car that has had the head shaved too far. It has another head now. But when it had the head I bought it with, I had to retard the ign otherwise it would detonate with 98 pump fuel. I tried AVGAS in it once. I could then advance ign to correct value = more power. But just tried it once. There was ONE garage that had it, and it was expensive. Alcohol fuels burn far slower (less volatile) and again are used to exploit higher comp ratios. In a standard engine pointless. I took home three 44 gallon drums of AVCAT to run my heater. Because it is kero. It was past use by date for our work helo (navy version of Bell 206) and "had to be disposed of". Here in Australia, many had "oil heaters", so called because they used to run on the old "dirty crude oil" (ships ran on it, called it furnace fuel oil), but they cleaned up, so it disappeared. The oil heaters then ran on deso or kero. I didn't tell anyone "how I would dispose of it" because people's mindset is "car is x horsepower, jet engine is FAR MORE horsepower, therefore, jet fuel = FAR MORE VOLATILE!!!!!" If I told anyone I ran my heater on it = "Idiot/blow yourself up/heater will take off and fly to Bali" Heater ran fine, exactly as usual, because................................................... jet fuel is KERO. The moral of the story is (and most know) use the fuel your engine is designed for. OR if you have to use a different fuel, modify engine to use/exploit that fuels benefits. But many still have the "makes a jet fly/it will make my bike/car fly as well" idea. You can't tell them otherwise. SoI am off to drink some AVCAT, so I can fart and fly to Bali. 🙂

here in Brazil alcohol is a common fuel and can be found in every gas station: most injection cars and some bikes are "flex", you can use [and mix in every proportion] gasoline and alcohol (biggest bikes aren't flex, though, and I don't know why). As far as I know, alcohol needs 30% more fuel compared with gasoline: it means 30% more open time for injection engines or 30% bigger jet size for carburetor engines (worth to mention that brazilian gas already contains at least about 25-30% of alcohol). Alcohol is slightly more powerful than gasoline.

I'm adding razor blades to my bike as we speak. Left em in a rain barrel so they rusted up too just like uncle Joe n the boys used to do it.

" 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

I am so glad I couldn't afford a OCC bike back when they were on TV, it's simply obvious they build trash. Now that I can afford a custom Chopper I am going to Count Kustoms, Shannon Aikau builds a real man's bike.

Wow what a bonus the Revtek motor and Baker transmission
