Respect the workmanship and ingenuity. Many people believe 2 stroke engine's reliability stems from its simplicity. Looks like a lot of extra things that could fail. Enduro riding can take you miles from civilization, would have a hard time trusting all those electronics! KTM for example a multi billion dollar company, took them years to get TPI right... still the coolest thing have seen today!
wow, unbelievable I cant believe you custom setup the bike with efi. I didn't know it was possible. I really like the 150 efi badging that you designated it as. great video!
Great work as usual Dave .. The only thing missing in this clip is the Horse power achieved .. I was patiently waiting for the pony count .. but it never eventuated .. hopefully next time.
Hi sir just watched your video and repeated twice, saw your passion turning into hard work. Excellent informative video for 2 stroke lovers, as my knowledge it's based Alpha n algorithm map, I appreciate your hard word and thanks sharing Beautiful information, I want to know what CC injector did you use in primary and secondary fuel injection, triggers wheel setup wheel offset angle, and which sensor Hall or VR
This is really great! Any chance you're considering looking into a 250 kit? Sounds like it may just be a different cylinder head, and everything else basically stays the same. You've obviously put a lot of time and effort into getting this system right. I would be very interested in one, of course based on price. Any idea what the commercial cost would be, if you start producing these kits?
The other thing I was thinking depending on the oil Entry. Is if you're running the oil and the fuel through that fuel injectors it's probably why you're having the pop and sound. Number one those fuel injectors are made for fuel only. And it seems as though that fuel doesn't atomize , aswell ,when it's mixed with oil. I would love to help for free, just respond to this comment I don't have Instagram Or any that stuff
This is awesome! Great work! I would be very keen to get a kit for my 125. Have you thought of starting a kickstarter page to gain interest and get the ball rolling?
Nice job. So many questions. Check into a provisional patent. You didn't mention about the oil, injected or mixed. Is your ECU Arduino? Possibly look into changing your expansion pipe for the misfiring or Panic Rev. Also do yourself a favor and have somebody who's way better than you ride that bike. Well done mate
What a kick ass bike. I wish Yamaha would jump on this. The only thing I would add is electric start. Get this beast in the hands of a major publication for a test ride.
@Joseph Quīnque gnarly hill climbs and technical riding. Trying to kick start on a steep, off camber, rocky hill is tricky to say the least, sometimes damn near impossible. On a 6-8 hour ride, kick start can really sap a lot of energy.
Ive tuned many Lectron carbs on the dyno and although they can be made to run very well (like any other carb) they’re not even playing in the same ballpark as EFI.
In interested in doing a fuel injected 2 stroke build, but I was thinking about taking a throttle body from a kx250f and making that work, and using a minisquirt ECU. The problem im facing is i cannot rap my mind around how to do anything with the ECU, How do you time it to know when to inject gas, how do you program it to inject a certain amount of gas? The whole idea totally confuses me and if there is any advice you could give me it would help me out a lot! Thank you.
There are several ways fuel injection "knows" how much fuel to inject. On a 2T you're looking at RPM and throttle position as your two main variables. Air temperature and pressure would be used to make fine adjustments and engine displacement would be your basis for the initial calculations you make to get it in the ballpark and get it to start and run.
@Shaun McGrew Incorrect. More oil gives more power. I'm running 28:1 yamalube 2r in my 2016 yz250x. I have used the same spark plug for the last 125 hours. I have never fouled one. I'm that fast either....mostly trail. Why 28:1? That's what it took to pool 3/16" oil in the bottom of my crankcase which is how you set your oil ratio. You want 1/8" MIN. The pv wipes off clean, at TE change outs. If your fouling plugs, that is a a/f, or jetting, issue, not a oil ratio issue. If your gumming up your PV, your using the wrong oil, probably a race oil when your not racing. Anyway, more oil gives more power, better engine life, runs smoother. Up until the early 90s it was 20:1. Now it is changes for EPA reasons. Gorgon Jennings did a test on a 250cc 2 stroke. After correcting the jetting it made 15% (3.7hp) more power at 15:1 as 30:1. It dosent smoke that much more either. You have to jet for your oil ratio. All modern mx bikes come overly rich with the float usually set too high. Check it out: www.bridgestonemotorcycle.com/documents/oilpremix6.pdf
I have a 29cc 2 stroke that turns over 15,000 rpm running 16:1 that has never fouled a plug. I also have a 3.5cc nitro/methanol fuled engine running over 30,000 rpm. 17-22% oil, or about 5:1 and no trouble with fouled plugs either.
If Yamaha doesn't contact you to work for em. I'ma be pissed... Lol. Need these dirt bike manufacturers to make 2 strokes with efi
No problem. I had the exact same opinion until I got more into trail riding. Now it makes sense.
Has to be the coolest thing I've seen in a long time
What a beauty, really digging the mods and quality of workmanship
Dear god, this thing is beautiful.
id be interested in purchasing one

Incredible bike. I would love to see a riding video
The Best Channel!!!The most Underrated Smart Guy in UA-cam 💯 for Dave from Australia!!!
I would definitely order a kit if you make one in the future 👌🏽
Great work as usual Dave .. The only thing missing in this clip is the Horse power achieved .. I was patiently waiting for the pony count .. but it never eventuated .. hopefully next time.
40 hp he said it on Facebook
You are seriously onto something. Sell kits for the 125 and 250!
Yamaha! Please wake up and see this great technology, runs very crisp. Would like to see it in a YZ300X if you please, with lots of torque down low.
Awesome bike man! Can you say what brand ecu you're using? I always wanted to try this with a microsquirt ecu on my old banshee
I owned a KTM 200, it is a 125 with an extra 75cc. Best dirt bike I’ve owned sense my PE 175 Suzuki.

This is great, I’m so impressed, where are you, I’ve an engine I’d like your expert view on regarding fitting injection.
VERY IMPRESSIVE!, definitely gives me a ton of confidence in your KTM ECU/Head Power Kits.
Your rev issue (missing) may be averted by having the injectors in the transfer ports?
Beautiful bike brother.
Want to ask if what materials you used, planning to make one
BEAUTIFUL BIKE, DUDE!!!

This bike is so great. I Love it. Great work!
Yamaha doesn’t care!
Very well executed! That is so cool!
I just bought 94 YZ250 with EFI conversion.where are you located?
Very very cool. New sub here. What ecu are you using. Something like micro squirt or custom?
Amazing content, thanks for the videos.
Hi, what ECU are you using?
Riding video should be done to see if it works.
Very interesting
How much difference is there in the 144 over 125? Positives and negatives?
Yamaha - Hire this man!
sexy build, can you share any info on the pump? is it a standard automotive thing or some other stuff?
jnuxca it’s a standard pump that’s fitted to many ktm 4 stroke models.
@@TwoStrokePerformance thanks for the info
What are you using for power for the fuel pump and ecu power? A total loss battery system?
That's awesome. Good job.
amazing work
This is sick dude how much?
Super rad. Why do you have a 19" rear wheel on there?
Because it’s an enduro bike motocross bikes have 19’s
@@honda8192 reread my question
Wdym Enduro has 18 inch
It started as a std 125
If you don’t mind sharing, what ecu are you using in this application?
Amazing great job 👏🏻
Brilliant
Future-millionaire
Andy VonBurg haha lets hope so!
Two Stroke Performance i wanna buy a complete bike!!
id be interested in a "universal" kit!
Clever dude
Do you think this package would be practical or beneficial for motocross?
Brendan Adams 9:10
Did you have to alter oil fuel mix.
Mark Lupprian no it runs 40:1 premix through the injectors.
@@TwoStrokePerformance single oil injector single fuel injector ?
A Lectron carb would be much more convenient and simple. But really nice job piecing this thing together with the efi
Ive tuned many Lectron carbs on the dyno and although they can be made to run very well (like any other carb) they’re not even playing in the same ballpark as EFI.
@@TwoStrokePerformance so the efi has more power and better throttle response?
@@TwoStrokePerformance imagine efi on a banshee..
Two Stroke Performance Are you in New Zealand I would be keen to install into my project 250cc two stroke quad how can I contact you?
Is it alpha n only?
Hey can you send me the link to the parts please?????
But a bigger down pipe on it on that bends round like a DTR or YZ 250
Not enough Mad Scientists in Australia
Well done
Next level stuff! Cool channel all around. Sub'd
Sweet
I want this
The oil mix,how do you do it?
André Ferreira mixed into the fuel same as a carby
@@TwoStrokePerformance great work,congrats!!

I wish yamaha would do fuel injection they can do it like to see them take it to ktm
1 2 5 😂. Just say it’s a yz125
Kt100 manco
Hm
32:1 is as lean as you want to go on a 125.
Depends on fuel-air mixture
Ktm says 60:1 from a 65cc to a 300cc lol.
I agree though. There is no benefit to using less oil except using less oil.

Colossal waste of money... if it’s not TPI.
