mini bike fuel comparison which will run better?
Tested the 212 Predator Ghost powered Azusa mini bike with 87 octane gas from 0 to 30 and then re-tested the bike with VP 110 octane to see if there was any difference in performance.

Wow you are awesome for this content that you show us your fans! Your always keeping me inspired with your work thank you so much and please keep up this great content 👏👍🏽

[@Black66]

Thanks for watching!

[@FLORIDAMANIAM-he2lz]

High octane fuel just allows you to run at a higher compression without damaging the motor. In japan the average fuel is about 110 octane because alot of their engine desings require high compression to get efficient power out of small motors.

[@Black66]

Yes, thats what I was saying at the end of the video, I might do a follow up video with more compression and timing . Thanks for watching!

[@billbalke7572]

You need more compression to see the performance out of the 110

[@FLORIDAMANIAM-he2lz]

You mean the 110 would allow you to run higher compression

[@dennispage5333]

You do a great job, Thumbs up.

[@Black66]

Thank you very much!

[@Gazanova85]

This video was very helpful. Love you black66

[@Black66]

Glad you enjoyed!

[@dmann1209]

Excellent comparison and content. I use the 90 ethanol free fuel in my vehicles and powersports. It has been said it is stable and will not separate. If you choose to make those adjustments, I will definitely watch. Thanks

[@davidpearson8043]

Do you do mini bike tune ups in AZ? Love the videos!

[@jamesgravel7755]

You should just try E85. You need a 30% larger jet. Or get 5gal of E90. That race gas is only really gona help with a really high compression motor. If it runs with out detonation on 87 the fuel isn’t really gona help much. Smells better. Lol. But E85 yeilds about a 7-10% increase in HP on most engines. On the boosted applications we built it was more like 30% more HP.

[@Black66]

Yes, that is what I mentioned at the end of the video. We have run methanol on many race karts. Pics are in the community tab.

[@mikeashbaugh7773]

Love your videos, been watching for a few years now, I have built a couple of mini bikes but nothing great, what is a good start in your opinion for a drag bike, just a fun knock around on a budget?

[@racerothery2716]

Bro guess what I did… I was hunting and searching and praying on how I was gonna extend my swing arm from 14 weak little inches to something atleast 4-6” longer. Well I randomly landed on an EBay listing for 08-12 Kawasaki Ninja 250R Swing arm and pivot bolt and axle clips… everything. The swing arm looks exactly like mine but it’s 21” and same spec on everything else. It’s an amazing win for custom built bikes everywhere. No cutting and welding anything but the shock mounts to fit my set up.

[@jaybones614]

Advance the timing on the 110 and see what happens. You will be surprised. Helps with high compression motors as well.

[@Black66]

Check out the playlist. I have quite a few timing videos.

[@WyFoster]

You want to burn the fuel in the engine your engine was designed for. If you put a high octane fuel in a low compression engine. You will lose power do to the slower burn rate of the higher octane fuel. You end up having to dramatically advance the timing to take advantage of it and this is just further increasing the inefficiency of the engine. The lower octane, and lower ignition timing you can run, the better. That means you have faster flame propagation pushing down on the piston at the point of most leverage against the crank throw. Hopefully I did a decent job of explaining it.

[@randywelch55]

I've run the same experiment as this on my minibikes. I found that the higher compression and bigger duration cams really respond better to the 110 octane (leaded) vs the slightly modified engines with 265 cams. I didn't see any benefit using higher octane in the smaller modified engines myself as your experiment shows. Now I've used 104 Unleaded in my bigger modified engines and they really like the 104 vs 110 but I do get a gumming build up of the piston and cylinder head chamber from the unleaded 104.

[@janicefullerton6201]

I would love to see you put the stock cam from the ghost inside of a stock 212? 🤔 see if the 0-30 is better and top speed is faster by how much?

[@Black66]

Just did a video on that today. it will be out soon!

[@ianfairbanks1318]

Would love to see you do a back to back 0-30 with stock hemi cam vs. an aftermarket cam. @@Black66

[@NubsWithGuns]

Seemed to not run as smooth on the 110. Might be just me being silly idk.

[@ianfairbanks1318]

I thought the WD40 was the best fuel ever? 😂

[@Black66]

lol

[@scottwiley]

The "smell" is the lead.

[@Samuel-ib6ze]

He's gonna get lead poisoning

[@racerothery2716]

What’s crazy is idk where I would even buy gas like that here in Oregon. Maybe a motorcycle shop or Motorsport shop but no gas stations here would have that. I have to put in Premium pump gas (93) and add octane booster to it to get it to 108.

[@D--5]

Some car dealerships carry race fuels. The local Ford dealership here in Central Kansas has several race fuels they sell.

[@D--5]

Keep in mind that octane boosters list their octane gains in 0.1 octane point increments. For example, one that lists it'll raise your octane 12 points will actually raise it 1.2 points.

[@COlson-rh3dg]

We used to go to the airport. They would sell us 100 octane airplane fuei. That stuff would take your skin off.

[@D--5]

@@COlson-rh3dg av-gas is also leaded

[@QuattroGP4]

Where do you get chains and sprockets for these predator 224 motors? Have a 12T clutch but cant seem to find a chain and sprocket combo to match

[@FLORIDAMANIAM-he2lz]

Gopower sport is where everyone goes for the most part. They got the best shit till to get into machine work.

[@Cereal_Killr]

Im not an expert, but the fuel would benefit most with timing adjustment and would allow a higher compression engine. Cool video! Thanks for showing us that high octane is not more power, high octane ALLOWS for more power.

[@Dachshund-Nator]

Question: I have removed a 5HP Briggs out of a tote gote and put in a Predator 212 with stage 1. With the extreme low gearing of the bike, is there a point where no more beneficial power will actually reach the ground? In other words an example of 10 HP versus 20 HP, as an extreme exaggeration example. I don’t intend to change any gearing, sprockets, pulleys etc.

[@lucassarchet6712]

Ive had a few gotes and similar bikes. No real benefit in more power as they are built for torque. Now, if you change gearing than yes more power is a good thing for such a heavy bike.

[@Dachshund-Nator]

@@lucassarchet6712 Thanks… for the reply. The clutch pulley on the crankshaft goes to a big pulley that says “power matic “, is that considered a torque converter?

[@lucassarchet6712]

@@Dachshund-Nator yes, it's a torque converter. A 20 series style.

[@Dachshund-Nator]

@@lucassarchet6712 Thank you… now I have to try and find out what I have. I’ve not yet found any pictures on the internet that look like this bike.

[@dallasjames97]

I FEEL LIKE the only fair way to test this is to again put lots of timing to it

[@Black66]

This test was mainly to answer the question on the average mini bike.

[@dallasjames97]

@Black66 Thank You for all your hard work! But....what happens if you DO put lots of timing to it wink 😉 lol

[@johnk6346]

Splitting hairs 🤠

[@Dachshund-Nator]

Interesting video. I’ve believed for a long time now that you’re throwing money away running higher octane on normal engines under normal conditions. Are you in the California high desert… IF you don’t mind me asking? 👍

[@Black66]

Thanks! Arizona

[@FLORIDAMANIAM-he2lz]

High octane fuel is for high compression motor. Its the motor that desides the power not the gasoline. Low octane gas will destroy a high compression motor.

[@Black66]

Yes, I pretty much concurred at the end of the video. Check out the playlist, I have gained quite a bit of performance out of swapping fuels in different bikes due to the stored energy differences in a given fuel. Thanks for watching! @@FLORIDAMANIAM-he2lz

[@6628guitarhero]

Sound like a run for no head gasket an +4 degrees of timing lol

[@dylanpicquet8149]

Your speed Spomer hit 60

[@eyehearther111]

Wow! So it really dosent matter what fuel you run. 🤔 interesting lol.

[@EBell-bh3gh]

Build a Tesla mini bike self driving 😂😂😂

[@Black66]

That would be a fun video!

[@Tyresong]

&3.50 a gallon? let me work this out... 3.785litres /$3.50= $0.925 per litre... compared to our $2.779 per litre... and "Americans" complain about the price of fuel? Race gas can't make more power without the engine being tuned for it. If you put an engine on a dyno and carefully worked up to the maximum possible output, and then did the same on race fuels, you'll be changing jets, possibly needles, fiddling with timing, and discovering more power, but it comes from the ability to tune it harder, not the fuel (and the benefit of lower emissions to create the exact same amount of power, like the EPA actually cares about saving the earth more than creating jobs for themselves!)

[@D--5]

Americans also drive a lot more than most Europeans (assuming you're from europe). My wife and I drive around 800 miles per week just going to and from work and it's not uncommon for us to drive over 2,000 miles when we take a trip so even though our gas is under $3/gal it still hits the wallet pretty hard.
