Thank you for useful stuff .I'm new to 2 stroke and this really help!

Excellent explanation of the oil mixtures. I didn't even put two and two together. I open the manual and used the recommended oil ratios. I didn't even think it "really" goes my the oil manufacturer, not the KTM manual. But, I still fell in the correct range for the AMS Oil I have been running! I will be looking into the Saber convenience. Thank you! Go KTM

Loving your work my friend. Thank you for information. 👍👍

Thanks fella, I've been Youtubing for a decade at least and had never noticed the little bell, lol, great vid'. I remember when the 'garage attendant' would fill up for you, and add the correct amount of Castrol.

I was using Yamalube, and 32:1 and because of your videos I wanted to Try Amsoil SAber.. Well I was cautious about running 80:1 or 100:1 so I mixed the oil 60:1 to start. I tried starting the Bike and Immediately fouled the plug and the bike wouldnt run. So I mixed the gas at 80:1 changed the plug, and the Bike runs Great.. Your Videos on (WHY) the oils are mixed at specific ratios are awesome. I had no Idea before why there were different ratios. Now I know.. Thanks

you could just save the bottle?

This is a good start, just bought my son a Suzuki 85 2018, brand new first time with a two strokes dirt bike. Not my first rodeo. My first son had a Honda 80 4-stroke. But this one is a whole new world. Gas mixture is very different, not only by with the recommendation specs for for oil from of the manufacturer. I want to find something that works overall and this is definitely is a good start. My neighbor who did Motocross with two strokes said have lots of spark plugs 🤣. you have to become a chemist at some point but don't let it over welm you.thank you for your video.

Good Info, thanks Kyle!

There aren't enough dirtbike lovers out there Kyle. You deserve way more subs. Quality content.

Thanks for the vid! For my street legal CR500 I usually pre-measure out Amsoil Dominator oil at 3.2 fluid oz into 8 oz. plastic bottles (easiest to find locally for me). Carry 4 with me in a ziplock bag inside my backpack. Ratio comes out to 40:1. I only have a 2 gallon tank so this is convenient to separate out by each gallon. I just have to stop about every 30 miles and add a gallon to make sure the next gas station won't be a problem. I have found a few 3.2 oz containers of weed whacker grade 2 stroke oil that I use as well. After I use it up on the whacker, I refill with appropriate oil for my CR. I do the same thing with pre-measured Klotz octane booster too. Most gas stations around me only offer 91, which runs fine, but I feel better giving my bike a little more octane.

Hey Kyle, can you incorporate more maintenance/ project videos in your list for future videos ? Then maybe like a similarities and differences video for 2-strokes and 4-strokes, for example: Gear oil/ trans fluid for 2-stroke compared to just motor oil in a 4-stroke or engine rebuild differences between 2-stroke & 4-stroke. Things like that. Basically shop talks. Love the channel.

As a 10 year Amsoil Dealer and a Saber user myself, I want to that you for explaining this better. My chain saw and weed trimmer run great at 80 to 90 to 1.

Dont have a 2 stroke but this was very informative, thanks :) by the way, you could calculate the cost of the oil needed per gallon and refill those amsoil bottles with the most economical option, just a tip

Good video Kyle, When I first bought my Beta 300RR I used mogul at 50:1. I saw videos from yourself as well as others racing about Amsoil Saber. I did tons of research before trying it, I was really nervous with the suggested ratios. I started using it with 10 hrs on my bike and now have over 60. I love this stuff, super easy to mix with the little bottles and I keep a couple 1.5 oz foil packs in my pack. Each pack works perfect for 1 gal of fuel in case I need to top off and don't have mixed fuel with me.

From the Motul 710 datasheet: RECOMMENDATIONS Mixing ratio: from 2% to 4% (from 50:1 to 25:1) according to manufacturers' requirements. Adjust according to your own use. take note it says "RECOMMENDATIONS "

KYLE,IN THE 60S I WAS RIDING A GREEVES 250 ,I USED AN OIL CALLED POLY-OXIDE,IT LOOKED JUST LIKE ATF FLUID,I MIXED IT 40 TO 1 AND NEVER HAD A PROBLEM OR A FOULED PLUG..IT WAS O GREAT BIKE..HAPPY NEW YEAR KYLE AND FAMILY..GREETINGS FROM THE PHILIPPINES

I like 32:1. Working on old chainsaws and such that originally was 16:1 gives it good lube with newer formulas. And have seen many scared up cylinders from those using leaned out 100:1. Plus it lubs things that have been sitting around for years better.

Just noticed your tire shelves; very nice👌

Maxima K2 40:1 in my 300 and 70:1 in my trials bike. Also 100 octane VP. These mixtures work perfect on both bikes

Exactly right. This guys got brains!

Thanks -good info that made sense

Great Video!

I found out it also depends on the type of riding.Motul (or Putoline) 50:1 - 40:1 When I take my 300exc to a motocross track and max 60:1 when I'm messing around on rocks and hard/slow stuff. Otherwise the sparkplugs tend to foul up.

I race A-SSR. On a 2002 ktm 300 , run AMSOIL Interceptor 80:1 for 10 years on the same bike. 1 set of rings so far and my compression is 190. With Factory jets and have never changed the spark plug. 2 strokes are awesome. I never mix it in the tank. If i had to, i would shake it up a lot before opening the petcock. I like the crisp throttle response and less smoke with the lean mixture.

I run Klotz, in my bike and in my R/C nitro. That Klotz smell with the nitro is heaven.

you answered my question. Great video

Love that you’ve had to make a video justifying your decision to use Sabre, lol. I’ve used Amsoil in my bike at 85:1 for years with zeeeero issues. Cylinders, pistons, bottoms ends having always been mint when I open the engine up. For me.....Sabre is by far the easiest, most cost effective high quality oil you can run. The small 236 ml bottle is perfect for mixing a 20L gas can.

It'll be good for about 1 1/2 years! I just put Sta-Bil in anyway (most of the time), that way you never get the dreaded "green float bowl", especially on the generators! : )'

Hey Kyle, love the channel! FYI, from what I understand, you are correct that a richer fuel oil mix (32:1 vs. 100:1) will result in a leaner fuel air mixture, however, in all practicality it's not because the mix becomes harder to pass through the jets. A richer fuel oil mix contains less gas molecules in a given volume (because oil is occupying or replacing the gas) and as we know, less gas per a given air volume equals a leaner fuel air mix.

After a long period of techical stuff, we got out in the open desert. He is a fast rider and started going fast.

You ever try dumonde tech oils? Not many people outside of Washington know about them. It's a company based out of Washington state. Their oil is really good! I run their full synthetic in my yz250's at 40:1 with a 50/50 ratio of pump gas and race fuel. My bikes have never ran so good. And it's a damn near smokeles oil. Perfect for my woods bike. I used maxima 927 for years. I never cared for the synthetic stuff until I tried dumonde tech. They make great gear box oil too. They also make a semi synthetic and a bean oil. Try it out, you won't be disappointed.

I run a full synthetic with 20% bean oil in the summer. Maxima Castor927 or Klotz Super TP. I think they are fairly equivalent, but I find better prices on occasion for the Klotz STP. These are not said to have good cold storage or off season corrosion resistance, so in the fall when it gets cooler I switch to the Amsoil Interceptor. Amsoil CS says the Saber is for garden tools, though I don't know why it would make any difference. Maybe it's just the same stuff marketed differently. (I've used the Amsoil 100:1 (@80:1) in all my two stroke implements for many, many years with no problem.) The Dominator is said to be race oriented and does not have the off season corrosion resistance that the Interceptor has. I run a CR500 with no exhaust power valve at 44:1. The Dominator is also said by Amsoil to be more for racing all out, and can lead to more crude build up on the power valve in other applications. I believe they recommend the Interceptor for power valve applications. As for smell you can't beat the 927 or Klotz STP, though the Amsoil injector oil I ran in my TS185 smelled pretty good as well.

More oil is better then no oil, I'm just gunna fuckin send it

Running a lectron 38mm HV with Amsoil Saber 100-1 98 Ron fuel. Tried 91 Ron ran like shit actually it didn't want to run and 95 was ok but 98 made it run cleaner idling and during starting.

Hey Kyle, great video. You didn't get into the big big bore. I run a 89 CR500 mostly in the woods, no racing. What do u recommend? Thanks

I guess you could always just get a bunch of small bottles and pre-measure whatever oil you wanted to use to get the same convenience. Would probably save some money that way being able to buy in larger containers.

Kyle, I wanted to take a moment and thank you for thought provoking videos. A while ago I caught your video on 2 stroke oil premix. You and I had an email dialogue. After our dialogue I began doing a ton of research on 2 stroke premix. I would like to say this is what I found. A couple of extra ounces more or a couple of ounces less will have a negligible affect on gasoline viscosity. You claim that the reason you run a higher ratio of gasoline to premix is due to the lubrication properties of the premix. This isn't the major reason you have success running less premix to gasoline. The greatest reason is the RPM's at which the engines spend most of their time. What I learned was that even the new fuel injected KTM's inject almost zero oil premix when idling. Then as the RPM's increase so does the amount of oil that is injected. This is to protect the engine parts at extreme temperatures and force. Now in a dirt bike that requires you to premix the oil and fuel, you don't have the luxury of variable Oil to fuel ratios, so you have use a ratio that best works for your bike/conditions. Since you're doing a great deal of single track riding the engine isn't spending most of its time in the upper RPM range most of the time. The engine isn't screaming nonstop like an MX bike does. Albeit the ratios you run work for you and your bikes, it isn't as much a condition of the grade of premix, but more a condition of the type of riding and RPM range you run at. At higher RPM's you need a thicker film of lubrication on the bearings, rings, etc. When a manufacturer recommends a premix ratio, the engineers select this premix ratio based on max RPM and insuring extending engine life. In short you're able to use less oil with strong results due to the lower RPM's your engines mostly run at and not the type/grade of oil you run. The other thing to consider is how well the rings seal especially at higher RPM's. The premix plays an important role here. The less oil in the fuel the thinner the film of oil on the cylinder walls/rings and that reduces compression especially at higher RPM's. Anyway, I wanted to share what I learned, and I did all of this research due to you getting my brain going. Also AFR is AFR, Running a thinner fuel or a thicker won't change the amount of lubrication. I say this because if the engine begins getting more fuel, or too much fuel, you'll need to lean out the fuel air ratio. If the engine is getting less fuel or too little, then you'll have to fatten up the mixture. At the end of the day the ideal AFR is somewhere between 12:1 to 14.5:1 Air Fuel Ratio. You can't run leaner without melting something down and you can't run richer without affecting performance negatively, You can't run a "thinner" fuel and believe you're getting more lubrication. The volumetric efficiency of the engine is static for arguments sake. That said, you'll need "X" amount of fuel for each revolution of the engine to maintain a specific Air Fuel Ratio. The mass of the fuel is more important than the volume. XX parts per million of air to YY parts per million of fuel. That said the volumetric efficiency of the engine is static, so you'll always need "XX" parts per million of fuel. The only variable is air density. The greater the air density, the more fuel, and vice versa. You'll reduce your engine life in no time running less oil to fuel regardless of the brand of oil premix if you let that engine scream. You're not getting additional fuel in the crankcase with a "thinner" fuel, unless of course you're running a fatter fuel mixture to air. I hope this makes sense and am happy to have further dialogue.

hey Kyle I was wondering with oil injection how would this work then? can you adjust it on the bike or is it able to adjust itself. honestly have no idea. great video never knew that about 2 stroke oil

Running Klotz 42:1 and the scent is like heaven

the castor oil?

Thank you-you legend

Running rich means a higher fuel to air ratio and is determined by your ecu, mix your fuel and oil as per the instructions on the bottle and u won’t foul plugs, every brand of two stroke oil can be a little different. Motorex is 60:1 Racing plugs won’t foul as quick as well, put a good quality plug in it

When my KX250 gets out the shop I plan on running Maxima SuperM with 93 octane gas from Shell at 32:1.

I ran my kx250 at 50:1 with no issues at all. The piston and jug still looked like new after a year of hard trail and road riding. I used golden spectrum oil
