Putting E85 Fuel in 131ci Harley-Davidson!

[@ianm432]

***A HUGE word of caution using pump e85 without a flex fuel sensor!*** not all pump e85 are created equal. Pump e85 can be a maximum of 85% ethanol but as low as 51% and if you dynotune at a low E content and then fill up at 80% the bike WILL run lean! You can get MASSIVE variances from pump e85 even at the same station from one fill to the next. You need to test the ethanol content. Test kits are cheap and easy to use.

[@JCunningham21]

very good point.

[@HashMaster1776]

THIS IS EXTREMELY TRUE ALL GUYS THAT RUN E FULL TIME KNOW TO TEST THE E AT THE PUMP BEFORE YOU FILL. LISTEN TO THIS MANS WORDS OR THAT ENGINE WILL BE TOAST!!!!

[@thehippiedog5956]

Lovin E85 for many reasons (more power, runs cooler, no emissions to worry about) It's a way better fuel. Hatein that it reduces your range so much on a small tank.

[@Diavolo_VRSC]

Should try doing a flex fuel sensor if your software allows mapping based on the sensor. E.g. the sensor will read the % of ethanol and the tune will be scaled in accordance with that percentage. This way, you don't need to switch maps.

[@ianm432]

The dynojet powervision and stock ecu do not support this. Most aftermarket ecu can easily do this, but I don't believe that includes the standard harley plug and play systems.

[@juliovaldes1377]

I been running e-85 on my lowrider for 6 months now, I have a great tuner and mechanic here in Miami and I’ve had 0 issues what’s so ever! Worth the switch. Ofc I can switch on and off with my dyno jet

[@Tubbyonasporty]

You said almost $4 a gallon for gas. In Cali, E85 is almost $4. 87 is $6.49. Really beginning to hate this place. Most companies won’t even ship parts here. 👎 great content, boys!! Keep ‘em coming.

[@donaldsmith6404]

That’s crazy gas is right around the $4.00 mark for 93 in KY.

[@Tubbyonasporty]

Yeah. We’re getting taxed to death out here.

[@g.o.b.2558]

The best thing I did was move out out of that dumpster fire... F Newsom...

[@donaldsmith6404]

Bad part is I bet y’all’s roads got just as many pot holes as ours but y’all pay so much more in taxes.

[@Tubbyonasporty]

I’m in a “small town”. We’re treated a little better than cities like LA or San Francisco. We have Buck Owens and Korn and Merle. They show us respect, Dammit!! 😂

[@justinbailey4603]

Been in the ethanol industry for the last 10 years. Was excited to see this episode! Keep up the good work guys!!!

[@evilwestsidefan9249]

Main problem is with compression and water in the fuel. The water content is why flex fuel cars have stainless components.

[@michaelmiller9966]

Great Job Chris.. another great video, hang on Block!!!! Woohooooooo

[@michaelmitchell5909]

Your bike is sick block....gotta be just an amazing feeling seeing a stainless pipe with your name on it on your bike man....probly my favorite M8 harley I've seen besides the road king special moonshine did for that old dude with the blue trim on it...

[@tommiller8714]

Awesome video with excellent info. regarding the Pro's and Con's of running E85 fuel in Harley Davidsons. Currently building a 132 Cu.In.[all S&S] for my Road Glide ST (daily ridden). From an Engineering perspective and IMO, the ultimate street setup would be a system that can detect [measure] what's in the fuel tank [all E85, all gasoline, and any mixture blend of the two...like the system in the 2023 Dodge Challenger Demon 170], and make tuning adjustments. The alternative obviously is to run a Dyno Jet PV3b ('21 & newer M8 HD; PV3 for '17-'20 M8 HD) with two tunes...1 for all E85 and 1 for all gasoline (91-93 octane pump). Great content!!!

[@mattmeazy9988]

Thanks 4 the info. I've been curious about e85 in Harleys. Thanks again.

[@harleydamian707]

@OneSikScraper did all the math and put kits together for this year's ago. Glad to see more folks trying it 💪🏼💪🏼

[@travismccarty515]

F#(%ing LOVE you fellas for this! Doing the "I wonder what would happen if..." for us and for science! Killer content!

[@LowRobert88]

My goal is figuring out how to get my bike down to you guys and get it tuned by Chris. Amazing work, very impressive. 👏 👏 👏. Keep’em coming! ⚡️

[@cyberpunk4622]

Next up on the fuel list is: Drumroll.... JETFUEL That's Crazy Science BABY!

[@Ensaumneak]

Interestingly, Jet-A is much closer to diesel than gasoline, so it unfortunately wouldn't work at all in a gasoline engine. You can actually run jet fuel in a diesel engine though.

[@cyberpunk4622]

@@Ensaumneak Well it sounded like a good idea, till you put the facts of truth and knowledge and ruined a perfectly good "SCIENCE EXPERIMENT!".

[@thehippiedog5956]

Played that big fuel game with a big block GTO back in the day. The problem is keeping the gas and JPF mixed. Trying it on my scooter soon...

[@derick-smith]

Chris is real as hell man. Gotta love a guy that shoots that straight. Amazing crew you've got there!

[@badlsxgarage]

I love e85! It’s like adding a power adder. IF you do add a power adder, E85 comes on even stronger and more efficient. Couple downsides, availability. If it sits too long it will gum up the injectors and pump. It’s a trade off. But what a trade off it is!!!! I’ve never done it to my bike but LS and coyote engines love some E!

[@jasongallagher7646]

Official Mac runs the e85 and was saying that he changes the fuel filter more often!

[@jacobowens8020]

Yall are a huge inspiration for me and my son he is 13 and we went and got him a sportster to build for when he is 16

[@sickwideglide]

I look forward to seeing it when he’s done!

[@jacobowens8020]

@sickwideglide I wish I could upload are progress so far ill send them in a message on Instagram

[@likefiftyninjas]

That's a pretty cool experiment. I don't envision this for my riding style but it is great content and information.

[@freedom6919741]

You guys rock ! Great info.

[@RickyRadar0848]

Thanks!

[@keithsmith9889]

Bro! Been waiting to see this!

[@twowheelsatatime]

Great video, loving the content. Very informative.

[@bobbendt1698]

Good to see you guys figure out whether or not it will run on E85. I know my son has his '04 Cobra on E85 and FL is pretty light on E85 stations when we were down there drag racing last Feb. His car has a flex fuel sensor so it automatically adjusts his tune based on alcohol content. Great video and I'd be curious on longevity with E85.

[@mrchopboogie]

Cool to see this experiment. My brother’s got a ‘12 corvette with some engine work and and super charger. His computer recognizes ethanol gas, adjusts, and makes a lot more power.

[@Jonathan-L]

Wow, that light system in the dyno room is amazing!!!

[@ET0000]

Awesome video guys.....a real eye opener!!!! 😎

[@godsmack7734]

I wonder how a Rev Max engine would run E85 🤔

[@the_j_speed]

Favorite video and content avenue yet 👏🏻🏁

[@shane8493]

Here in South Dakota E85 is almost offered at every gas station because we promote it for the farmers. We have 16 ethanol plants in SD. So, if you need E85 we have plenty 😁

[@jeremysartwell7171]

Not west river plus run 100 octane real gas see what makes more power

[@slimalcina]

Alot of timing is the key to making big power with e85. Chris needs to test the e85 to make sure its true e85.

[@kenwright3919]

Awesome as always it seems

[@secondhandbikers]

Chris is the kind of guy that would cause me, (if i was in America) to visit the workshop daily just to mess with him and get on his nerves.. but that's also because i think we're a bit the same.. great channel guys, much love.. and Chris, dont forget i love you..

[@gavincarrico7126]

Hell yeah love that y’all are starting to make your own products! You should call them the block headers

[@MichaelBertini]

1. Awesome tests in the name of science! 2. You did it on that expensive bike (Goldzilla) 😂🍻🤘🏼

[@donbraham411]

Awesome man it sounds sweet

[@philvale5724]

Hi 👋, BlockHead . That was very interesting, incredible amount of power increase, and I’ve noticed, and I think you said about your exhaust, his way way too short, I do not know anything about the dynamics. Exhaust building know about engine tuning, especially when it comes to electronics., but as saying that I had a stock 1999/2 Deuce, 1450, Then put a big bore kit on it. I’ll change the cam, carburettor, ignition, module, oil, pump et cetera, and I tried at least three different exhaust systems, I ended up with a DD what I think was called a boom can, I’ve even tried approaching them a few months ago to see whether I can still purchase one of these. I just did not get any reply at all. , I think it might of been a one-off in some respect as it was for a magazine I think easy Rider, can’t remember, put the pipe seems to be a lot longer than what’s on your bike. The end of the cone goes well past the centrepoint of the rear wheel, and is a lot bigger in diameter, I think from what I can remember is around 5 inches. diameter. Ha ha size does matter, and this is when it’s cold😂, So am I right in saying that in a few increase the length of the pipe and the diameter of it, you will get more power on the top end , ? . Of course, the intake manifold could probably be either lengthened or shortened to either give you more bottom end, torque or top and talk . I presume you are doing a service on your bike before you doing this , change and oil et cetera , each time, Very interesting subject, engine, tuning and performance, where you gain on one side, you sometimes eventually end up a loss engine blow, Good luck for the future. Look forward to watching and listening. Ha ha to your next performance update. , Stay safe ride free , Phil from the moulin France.

[@feedrate1]

I use e85 in my f150 luckily the gas station up the street from my house sells E85 . It's cheaper the ether gas and you can tell the difference. This was very interesting good video 🤘🤘🤘

[@LJSiar]

I put about a gallon of E85 in my Dyna Low Rider S on the way to Sturgis, didn't really notice much. Why? I was in BFE and almost out of gas. As as I recall my mileage did go down. Glad I did not damage my baby.

[@icebrakernh]

I run from E85 cause of its low energy properties. It takes more E85 to make the power of 93 octane. But to explore is what makes things better.

[@darrenschneider9722]

Some small towns in northeastern Colorado only have E85 at times I have no choice but to put it in my 103 ,same with Nebraska.

[@brucemacneil6356]

Yall need to make a full length for a twin cam!! I would buy it immediately

[@hemi398]

Always enjoy the direction and candor offered in your videos. No buts. However I hope the audience understands that normal operation lives below 4,500 rpm 90+% of the time and someday you ARE gonna POP that sucker good and let the smoke out. I think Mr. Shelby said something about never having tooo much horsepower, but not finding enough traction is the real issue. Stay safe and don't burn down the shop.

[@pistonburner6448]

I don't understand what you mean by that. Pop what, let the smoke out of what and why? And what's that about traction? And why would the shop burn? You seem to be expressing multiple different concerns, but you're not actually saying which concerns and what to do to avoid what you're warning about.

[@ecrusch]

In the name of science! For the community! (My inner 12-year-old STILL gets thrilled by seeing my name on that fairing)...ha ha Thank you for everything you guys do to help us out. Peace. Eric in Kissimmee.

[@Big88Country]

Good stuff gents!! Appreciate y'all!!

[@tommyjusz]

up in Chicago E-85 is almost 50cents cheaper than 87 octane, and its quite abundant

[@berlow7]

Def either put a gm flex fuel sensor in there to monitor ethanol content and do a full flex fuel tune to have it adjust on the fly based on ethanol content or spend $10 on an ethanol tester and don’t fill up under what it’s tuned on. E85 can legally range from e70-e90 and can affect AFR’s. For us in states that have cold weather we also get what’s called winter blend with can be even lower than e70. Ethanol is a corrosive fuel as well and shouldn’t sit in lines or injectors too long. You could get gunk built up under the tips and could clog passages from being gunked up causing a flow issue which could lean out. Ultrasonic injector cleanings on a machine annually or bi annually is a good idea or don’t always run it to let 93 clean out the tips. I run ignite red and buy barrels of it for consistency. I would be very curious to see what Goldzilla would do on one ethanol r. That’s a killer fuel. English racing does a very good video tuning an evo full flex fuel where they do a full map starting on e10 and pouring in 10% more ethanol and doing another map so there’s a map on e10, e20, e30 etc and gained like 600hp throughout the tune with a gm flex fuel sensor and it will be able to switch maps on the fly based on ethanol content

[@KeViNMCMXXCIX]

Hehe that's some nice gains! Goldzilla rips.

[@araxavionfinnie552]

Basically e85 runs cooler which is where the up to 20% bump in power comes from but with forced induction you want e85 since it increases your ability to increase compression without causing detonation due to its high octane levels.

[@gasman6922]

I like science more and more every episode!!!

[@119topdawg]

Interesting, didn’t realize using E85 would be that dramatic an increase, with the appropriate changes of course. Good job.

[@TimBarnett-pl9kd]

I did a milage study on 03' FXDX comparing regular an high test fuels? Motorcycle ran fine with no damage. Effects were slight decrease in both milage an power, but almost unnoticed. I have an oil test machine an have tested major oil brands too. Octane is measured in tenths. So, if you read label increasing octane by one point, that does Not mean from 85 to 86 octane. That means 85 too 85.1 octane. My 88' GW, with Honda car motor is designed to be used in a car with regular fuel. So operating in lighter motorcycle is ok to use regular fuel! Two thing will happen with too much octane in fuel. Pre- ignition on deceleration exhaust pop, an reddish coloration of sparkplugs. Deceleration pop is my indicator an I don't care about reddish colored plugs,!

[@estebansantos7314]

I need that exhaust ASAP

[@ALPHAFTUCK]

BEAST!!!! What about once you're tuned for E85, can you run Premium after without retuning? In Alberta Canada and noticed E85 isn't at every fuel station....

[@tex9280]

BIG G'day guys from Down Under 🇦🇺 Love all the science 👨‍🔬🖤🧡🖤 Chris telling the truth & calling out BS is awesome & don't change ❗💪💪💪 May all your days be Harley days🖤🧡🖤 Safe travels 🙏♥️🐾🐾🇦🇺

[@40indyuk]

Think his alleged bullshitters are from Oz

[@AlittleBitOfFun]

Here in Australia we get premium 98 octane with no ethanol at every station, I run it in my bike for the cleanliness and longevity of the bike, I've been told the m8 with only a stage 1 won't see the benefits above 95, but in my experience all my engines run better on it. Interesting story, my parents blew a head gasket in their car (due to leaving the radiator cap off) and although the car had 200,000+ kilometres mileage the engine was still squeaky clean and perfect inside due to only ever being fueled with 98 premium

[@someonesomewheresomdeday]

98 octane in Aus is the same as 91 octane in the US. The formula used to calculator the isomers is done differently in different regions.

[@robbierussell9536]

You're the MAN CHRIS!!!!!;

my guess is 6 hp and tq.... and I was close.. keep up the fun work yall cheers.

Bad ass! Thx!

[@RickyRadar0848]

This is great info~bad ass

[@Manonymous108]

Watched other videos of bikes built for E-85. The only drawback is it seems to clog the fuel filter in the tank, and you end up replacing it every 10-15000 miles.

[@ariellepascale]

That looks fun to ride on E82 , now you guys should try nitro methane

[@2remaynSPorter]

Can’t wait to meet you guys, master tech be keeping it 💯 and block “you the man 😎 “

[@thehippiedog5956]

Get a old carbureted scooter, get a extra carb and a simple toolkit, rejet the carb for E85, carry the original gas carb for when you run out of E85 (and you will). When that happens... Find a gas station... Screwdriver and wrench the E85 carb off the bike and replace it with the gas carb in your saddlebag. Then kick it and go... 1/3 the mileage with E85 ya know :-) Bike trailers? Pull one and you won't leave home without it.

[@miguelsaucedo6248]

I volunteer to let yall do it to my sportster, lol.

[@jproper]

I'm gonna wait to buy an exhaust for my 21 FXST until you guys re-launch. Polished or chromed pretty please 🙏 😂

[@freyatilly]

Ugh! Not E85. In UK we do have 85, but also 97 and 99. For the 85 there are aditive boosters and protectors. My next search is for Ethanol free, leadfree for domestic vehicles.

[@jamesco0329]

How are you still running a stock drive train? I have a stage 1 set up. And toasted my compensator. I'm no where near your herseper, in a Goldzilla. Great video again, I'll stick with pump 92 octane. Have you experimented with nonethanol?

[@williamlouis4981]

Was hoping thundermax would come out with a way to monitor ethanol content and tune for it on the fly

[@mickmicko2720]

I get 86 extra hp atws using e85 in my 2004 custom sti ;)* though im only tuned on pump fuel now my computer couldn't handle the flex tune, always playing up! In my opinion e85 only good for racing.

[@roncoburn7771]

great video how do you guys drain the old fuel out of a m8 fuel injection i have tired with no success didn't want to turn the tank up side down ?

[@fleetkorrelljr3651]

Flex fuel cars have plastic fuel rails and plastic fuel pump components due to the corrosive nature of the fuel,and I have run it in my daily driver that's not flex fuel and it idles and starts alittle hard cold but runs ok otherwise

[@raykarr5633]

When’s the gold Trask coming? Let me get some short block head ends for my Aprilia with the left and right block.

[@keithsmith9889]

About maximizing.. e85 is ideal for boost! Just gap the 2 top rings and could probably run 20 poundds of boost. But seven pounds now it would probably be ok and north of 210 hoarse power

[@JBronson]

You mentioned you used recluse clutch plates in Goldzilla, what exactly did you do to the clutch? Plates, basket, springs etc?

[@Cypress9090]

That's huge power 🤟🏼

[@kenzistoen6668]

Not knowing. But you guys are just now getting e85? Up Here in MN we've had for 10-15 years.....

[@someonesomewheresomdeday]

Did I miss where the timing changes were addressed? How much more advanced did you go with the ignition timing? That's the real way to take advantage of the motor octane of e85.

[@2remaynSPorter]

Yeah let’s F around and find out!

[@CraigSmith568]

I would like to see the results on a bone stock bike. I'm thinking there would be little to no advantage. Just like running race fuel in a stock bike that doesn't need the extra octane it actually hurts performance. You really need to build the bike for performance to take advantage of the e-85.

[@joeplem5329]

I want Justin to ride Goldie to see how fast it truly is!!!

[@lifeofjustinjames]

👀 funny, I’ve never road Goldzilla yet 😮

[@27jazman]

If you are tuning with a flex sensor are you adjusting the bias so you can run either pump or 85 or even a percentage mixture that we have been doing with cars for the last 15 years. its not new technology and been around for a while. please advise.

[@Twk888]

Hey what would you guys recommend for a - 107 m8 road glide and I’m putting in a 124 power pack S&S kit What do you recommend for a Intake and throttle body ? Do u suggest 64 mm ? I think I’m going to do a recluse clutch but wasn’t sure about the rest

[@jasonkimble8926]

Just hard to find it. Good for racing. It does burn dirty, change your fuel filter every 3000 miles.

[@stangkillinS10]

I'd like to see the fu sportster on 85

[@cfmartin568]

I’m curious how much timing were you able to add or did you get those gains with the same timing? Most people that gets gains from the e85 is from timing

[@MorganPerrine]

Hey, I'm in NYC and need to get my bike tuned. But I can't seem to find great reviews or good info on tuners in the tri-state area. How do you find the best tuners? Or if you happen to know anyone in a few hours of NYC, would love that info too.
