- In this video we are building another electric dirt bike, this time we are modifying the dirt bike engine and installing the electric motor into the engine so therefore we can still have the 6 speed transmission and clutch.

I'm an old machinist 34 years in the trade and I have enjoyed your projects for a long time now...and I have been impressed with your engineering skills as well as welding ability but I have watched you wrestle with machining things ...I'm happy to say you have made great strides in that area as well now ...Nice work !
Yes Sir,..absolutly. He is the perfect son in low for a old machinist like me to.
I'm a former tool maker and mechanical engineer who worked as a steel machining engineer. He's not doing any engineering.
I can pee straight up in the are 6 feet and not get wet…some say I wasted my time perfecting this skill but they obviously aren’t getting free churros and popcorn at the county fair like me 💪
@@theupscriber65hmmm..... What is an engineer? Care to explain? Because I found two answer from googling and it's similar but one state "professional" and other state everyone that build, create, or maintain.

Don't get me wrong, I just purely ask. actually there was still a lot more answers from different forum or website, that just makes me confused, so I just want to ask straight from the engineer it self.
As a 2 stroke enthusiasts this hurts but at the same time it's super cool
There are still plenty out there.
@eriklarson9137 where i live, they aren't that common. From time to time, a clapped out will appear for a premium. But still i still like it just hurts a little
Hurts me too man. I am not a fan of this whole electric motor thing and I'll never own or operate anything EV. If it's not running on dino juice I don't want any part of it. But I guess it's pretty cool what he's doing just not my thing.
Hate to say it but with the speed battery tech is advancing now because
of the war between EV car manufacturers for your $ these types of bikes
are the way of the future and i can see most gas bikes gone in another
20yrs or so.
Everyone said that when they rode on a locomotive and threw firewood into the firebox)))
And talked on a wired telephone or sent carrier pigeons
You're not going anywhere!
After all, you travel by train and it is often already electric and there is no dinosaur juice))))
Все так говорили когда ездили на паравозе и кидали в топку дрова )))
И говорили по проводному телефону или посылали почтовых голубей
Никуда ты не денешся!
Ведь ты ездите на поезде а он зачастую уже на электротяге и никакого сока динозавра ))))
My man just flexing on us now. Making his own gears n sheit...man congrats. You're such a pleasure to watch
I'm a gear technician, and I've been machining gears for 36 years, mostly spiral bevel hypoid gearing, but also some parallel axis gears like you're making. You typically want .005-.006" backlash between your gears, and the idler gear is usually adjustable between the fixed axis gears. A sliding arbor on a T slot would work. Good video, and keep challenging yourself!
Love the positivity and knowledge
Лучше вместо коленвала прямой вал, а со стороны генератора зубчатые шкивы для зубчатого ремня. Надёжнее и передаточное число можно выбирать
Цепь сразу на корзину сцепления лучше. Паразитная шестерня быстро износится и будет шуметь
Would you consider helping a french guy in my fast charge etrike project?
I have no idea what you are talking about but machining shit fascinates me
I never imagined it this way, I already think it's fantastic
Also, I just wanted to say that you have come a long way from small jacked up carts super slow to being able to build anything you set your mind to. From fluxcore wire to mig and tig. Also your projects are freaking awesome now. Your ability to work from a shed blows my mind. I can't wait to see you get your shop. I believe you will be limitless. Hat's off to ya buddy.
This was really entertaining ! Electric conversions are awesome and you doing great job, I hope those new gears won't brake apart at high rpm...execellent idea !
You are becoming quite a bad ass fabricator! Excellent work!
I’m loving those 90s style graphics!
I remember about 10 years ago I used to watch a kid on TH-cam who made all kinds of sketchy motorized things from whatever junk he could find lying around. I wonder what that guy's doing now. 😉
(Be proud, you've come a long way!)
All that sludge is clutch friction material. Seems that Bike had the clutch burned up and replaced, but they never change the oil.
that’s how people blow up four stroke motors when the clutch burns up it clogs up the oil pick up tube and all of a sudden zero oil pressure. I’m on my street bike if I ever burn up a clutch pack, I always drop the exhaust so I can remove the oil pan and oil pick up tube. Always end up removing a handful of clutch. Ask me how I know😊
35:00 Love your C.A.D. programme... 😂👍
Harder is always better and this is awesome.....
It will be interesting to see how you maintain the oil bath that the clutch and gears have. Thanks for the videos! 👍👍
That's what I was wondering too!
Very good machining,man👍
Hey man absolutely love watching u work, kind of get mesmerised watching the lathe turning and machining, just a thought have you thought about utilising the petrol tank space to hide/conceal the battery and wiring?
the bits in impact drivers are the wear item.
Doesn't matter if you buy snapon or pittsburgh, you are going to shatter impact bits.
even if its gonna be cool its sad to see a mint condition bike get destroyed
On another note, it's very cool to see you push yourself out of your comfort zone. Very refreshing
My fave dirt bike of all time is it a 1992 model?.
This was my favorite video you have done. I can see your confidence growing, i see you not worrying as much about what your viewers are going to say. Your tools are getting better, your knowledge and experience is growing. All is all you are killing it. Keep it up. May god bless your future.
one thing I notice is the metal shroud around the motor. you may face some problems with it due to Lenz's law if its aluminum. even though aluminum is not magnetic a passing magnet can induce eddy currents which can cause the aluminum to generate a magnetic field which can cause a loss of performance and may cause the motor to cog/act odd. one thing you can do to prevent eddy currents is to cut slots in the aluminum. I don't know much about Lenz's law but I know how big of a pain in the butt it was for me.
That dude Tom Stanton on TH-cam had a problem with the lenz law on his homemade e bike I completely forgot about that
@mondude9754 thanks I'll look him up. it sounds intriguing. I've not heard a lot of people talking about it even though it can cause such an impact. Something so consequential should not be esoteric
@@zsds8455 yeah it was a real problem on his bike, and if I remember correctly, the aluminum around his motor was only around each end of the motor and the middle was clear yet it still had the issue
As a guy who loves older 2 strokes, could you find a 4 stroke dirt bike to cut up. SAVE THE 2 STROKES.
the bit that broke in the hammar screwdriver. was probably Philips, and the screw was probably japan industri standard. as the story goes the japan one is made different to break philips ans pussi ends. its the angels.
Reminds me of Le Dan U tube builds, where he makes 125cc motors into 500cc using 4 cylinders from junk motors, never seen electric motor cobbled in to one so this should be interesting, don't ever think your going to improve on a gas motor using electric it's not going to happen.
Man do it to a 4 stroke next time, save those 2 strokes, they're endangered.
Wondering if the electric motor spins both ways?
very cool..👍👍
This is both insane and awesome. After watching you run 5 miles of chains, im super happy to see you are doing it this way!
Electric is here to stay, once I see you are tackling more electric projects. Definitely watching this one closely with lots of interest (and enjoyment)
no shit, u gotta be public schooled af. its been here for centuries. literally.
Literally 🌈 @@handendaer
O HELL YES.... He's revisiting the electric dirt bike. 😃👏👏👏
Thank you RBW... 😊👍❤
Edit: A little surprised he hasn't found the Electro and Co 72v YZ85 and YZ250 conversion kits yet... It's the same motor and stuff but they have the mounts and stuff too so it would be easier to convert.
Edit 2: This Old Tony did a great video on gear cutting and heat treating... He gives a lot of good information on how to cut gears, the correct cutters and how to harden and heat treat them, I suggest if you're interested in making gears at home that you check it out. 😁👍
This man’s talent is off the hook ! Most raw talent I’ve seen on Social Media. Leonardo da Vinci of mechanical engineering! Amazing
A little sad to see a 2 stroke die, but project should be awesome
Looks like that motor peaks at almost 20,000w that's 26 HP. that should be comparable to original motor and will probably have much more torque down low.
I run mine at 32kw
those shots of the cog teeth being cut were mesmerizing :)
I'm not to that part yet... I can't wait!
សួស្តី❤🇰🇭🇰🇭
Awesome hear we go ❤❤❤❤👀👌🏴
why not vertical mount with worm gear for 90degree angle?
He told us why he moves from project to project,he gets bored working on same one for long stretches so he jumps around it reinvigorates his creative juices,to start again on old project with fresh new vigor as if it was new.i dont see the problem,hell kinda sounds logical.!!!snooky pa😂😊😊😊

Lol that bike was pretty clean I’d woulda rebuilt it becouse that year rm bring lil money . Nice build but you shoulda got a newer bike like a Honda that isn’t worth vintage money
Man I love the creativity but that old rm is freaking mint...... u couldn't find a junker?
You will someday lose your left hand, pls dont put ur hands close the sorvi when its rolling 🕵🏽♂️ hello from finland
I love the idea of using the gears and clutch. Having a clutch is such a huge part of getting a bike through corners fast. I'm definitely looking forward to this project!
An easier way I would have made this if you have to have the trans is to put a bevel gear on the crankshaft and mount the motor where the head goes? With the motor facing into the crankcase with some adapter? Final result might look similar to stock engine if the heatsink doesn't look too weird.
Brought a tear to my eye seeing a RM125 being pulled apart for a project, so,hard to find any 125 2T bikes now days. After seeing the booger welds on the frame and mounts. Not so hard.
(would love the engine for a kart)
I am not quite sure I understand. make vs buy gear cutter? could you not buy the exact cutter you need?
Really great eatch, every time I see that lathe on action and your ability to yse it improve I thank the generous donation.
Another cool approach to maybe consider machining side plates,as crankases to take the original bearings, gear shafts clutch basket, crankshaft output gear, mount electric motor etc.
Estas muy loco!! Cosa que me encanta!!!! 👍🏻👍🏻💪🏻💪🏻
Brilliant attitude and effort. Lets hope this build is reliable and goes amazing. Thankyou for all your time and work and keeping the fans entertained ❤
"We do these things not because they are easy but because they are hard" -John F.Kennedy-
All I know is I would love to donate to a gofundme or something for you to get a real shop with some real tools.
Apologies. Watched more and you covered this design to enable the battery to fit. I didn’t think of that.
a 2t dies for science!!!!!
I get it i really do but it kills me to see that bike being torn apart like this lol long live the 2/ haha
I'm sorry for sounding dumb here, but why do you need all that BS when the electric motor does all those things, clutch, gears, ect.... is that NOT THE POINT to just run a electric motor?
Exactly what i was thinking.
That electric motor might tear the clutch up, we shall see.
Such a great video!! I luv that you push yourself… I like learning and seeing new things. I see some channel’s in this space and they just booger weld junk together and sad enough they have more subs, perplexing. 🤷♂️ I am happy for them but it amazes me you don’t have more!!! Good job brother!!
Your SOOO it's like SUUU of Ronaldo hhhhhhhhh
I'm properly impressed with this challenge! I'm a toolmaker with 25 years of time behind me and the effort you just put into something in order to just teach yourself something is worthy of massive respect. 👏👏👏
I can not envision how you are going to lubricate your new gears without also lubricating your entire electric motor's exterior. And wondering about motor cooling in that thick aluminum tube. Enjoying the adventure though! Thanks for taking on new challenges!
What up early gang?
Prime example of how skill, creativity, science and engineering…. are completely meaningless without philosophy 😂. Taking a proven light powerful method of propulsion and swapping it with something heavier with far less energy density 🤔…yep no philosophy there
Am I the only one who cried when he cut up this gorgeous 2 stroke? Please use 4 strokes!
He used a two stroke so that the oil in the transmission will be sealed off from the crank case
I often wonder why more electric powered vehicles don't include the use of transmissions to maximize efficiency
Not generally needed, the torque band on an electric motor is wide enough without one. They would just add weight and expense to most vehicles. While it will add some utility, RBW is using one mostly to retain the experience of riding a gas dirtbike.
@@mlindsay527 Not true at all, an electrical motor requires 10x the current to start the motor from a dead stop than it does when its running at its rated RPM. They make motor savers for this exact purpose. I don't think there's enough real world testing to prove there's no gains with gear reduction. Such as in a Tesla there is some gear reduction it's not a wheel on the motor hub coming right off the shaft. I'd like to see that same principal but with interchangeable gearing. Low gear to start off and then high gear for highway cruising. Bicycles are a prime example. Why overwork the motor if you don't have to? Could see some real improvements on range imo.
the bicycle is the only vehicle that gets more than whats put in. engine or motor needs 16 tooth with a 44 tooth on wheel. bicycle is other way 44tooth driving a 16 on wheel.
How long until you make an electric off-road buggy? Nissan Leaf motors are very cheap and powerful. If you want to do it right with MUCH more power look into Tesla small and large drive units!
I have an add blocker so I don’t see the add. Instead the screen goes blank for 5-10 seconds while it “blocks” the add. This happens every 2-6 min.
i just skip them in under a second
Insane! Have you considered trying a vesc based controller for this one instead of a fardriver? I just made the swap to vesc recently from fardriver and the throttle response and torque are insane. Only downfall is the price for something high discharge is much more than a comparable fardriver. But they are much smaller in size.
So damn stoked for this build!
very interesting, maybe you will try in the future build some kind of electric reverse tilting trike
More B-reel! You are honestly the most humble fabricator out there.. showing us your mistakes, since we all make them…
Thanks!
Awesome work… your machining skill has blown my mind… great work!
You always keep amazing me Chris. Anxious to see how the gears work.
I did the exact same thing for my electric dirt bike conversion. I had just finished it when unfortunately my shop burned flat. And it was the bike that cause the fire. Well more so the batteries. 😢
i like your projects but... imo, i don't think gas powered engines should be converted to electric... electric vehicles are stupid
te complicaste demasiado en esa adactacion solo teias que quitar la viela y el sigueñal despues poner una barra de aserro donde iba el sigueñal solo restaria poner el angrane mas perque en el motor y el mas grande en el tubo de asero es simple rapido y veras ya ha motos que lo incorporan de fabrica usando las transmision de una 2T o 4T como de combustion sea
Use EN36 pack it in a air tight container with BBQ lump wood charcoal and bring it to red heat for a few hours. After this unpack the container and re heat the part to red heat and quench in water, the result is a very hard steel part, even carbide will not cut it.
All that fun, and you still have to cut the other side of the case. Yay. I was actually wondering how you plan on sealing the areas of the gears and clutch basket so it holds oil.?. You'll get it done. We trust you.
This is a great project, I love That your not afraid to try idears out your skills are never ending and your willing to put the work in so that your projects are a success I love your videos keep them coming man
Love this!!! So happy to see an electric bike build!
much better off to use a nitriding steel for the gears if case hardening is all you want. doesnt have to get anywhere near as hot, no distortion.
case hardening? you still have to heat the entire gear, and that induces distortion. also basically impossible to "localise" to just the teeth.
gears are normally done with a standard high carbon, then INDUCTION HARDENED. you only want the teeth hard.
a standard, common, simple ZVS circuit is sufficient for doing that, albeit you may want to use something like IRF460 for the FETs so you can push the power up and get it done QUICKLY... mount it above a tray of water/oil, get the teeth glowing nicely, then dump it all in, quick. or use a ring of copper pipe with nozzles attached and pump the quenching medium through when ready...
or use an "air quench" steel.
Let’s Goooooo!!!!! Next time a Cvo motorcycle!!!!!!!!!!!
My favourite RM generation, the 1996-2000, this one though with the 1992 graphics installed. I hope the engine you just butchered was sized and broken, otherwise a bit of a sadness...
WTF!!!! This is amazing!! Good job guy!! Only I've a little question, Why do you cut the gear with this tool? It's the same to do the chamfer with lathe? Thank's a lot!! Have a nice day
Absolutely amazing I been wanting to do this for a while now I own the QS165 built a KTM converted to electric with FarDriver ND72680 I built my own battery as well I’m absolutely stunned how well everything turned out wish I had a lathe man I could do so much I absolutely love all of your content I have seriously watched every single episode way more than once keep up the amazing work man. I’m 41 I been doing this same stuff almost since I could walk my brain don’t work any different lmao can’t wait for next clip thanks Man
Ever done any light welding? Shockingly expensive machines, but supposedly awesome results. For conventional welding systems, does frequency make much difference, other than amps? Considering using a gas in the heat treat furnace, something like Argon (if stainless steel)?
What year was that rm125. Dome of them cylinders are unattainable and expensive
Я думаю, что вместо шестерней проще установить двухрядную цепь, и менее шумно получиться
33:43 a DIY (large) sand blaster would've been perfect right about now to clean up the casings before welding.
If you do decide to make one, rather than buying one (IMO, they're really disappointing, you almost never feel like you're getting what you pay for) find a premade tank of some sort as the stepping stone. Maybe something like a large gallon tank etc. Spend most of your money on the actual sand blaster and DIY the heck out of the rest. They're really worth it, and whenever you paint or weld aluminium, they're good to clean stuff up before.
Its your bike, and I’ll watch regardless, but I don’t get running a gearbox on an electric. Gas engines make peak power and torque within a certain RPM range, so gearboxes are made so you can keep the engine in that RPM range despite your speed. Modern electric motors can deliver the power and torque across a very wide range of RPM. So you just gear for desired top speed and you’re done. I’m all for manual gearboxes, but it’s just complex, where the main advantage to electric is eliminating all the complex moving parts.
😮🎉 allsome work from cruzermans inventions 😁👍🦇🎉
I think your arbor tool tightening bolt threaded hole (maybe it's 10mm or 1/2"??) goes beyond the bore of the cutting tool. So, it's trying to break it in half when you tighten the cutting bit. Just a thought, I'll give you a SUB for trying...
This should be on TH-cam trending!
I won’t watch this.
Genuinely confused on how you don’t have sponsors… and help etc.
or how your channel doesn’t get more views.
(Other then you being a wee bit awkward lol)
Not I gotta binge watch your channel for the next 2 weeks!!!
I have the 250 version of that bike sitting in my garage…you’re killing me. You should’ve picked a motorcycle with a less persnickety clutch though.
Saya sangat menyukai konten anda.
Dan saya memikirkan. Apakah kedua penggerak ini bisa d gabungkan secara radial. Dengan menyambungkan as dinamo ke kruk as. Dengan menggunakan gear. Sejauh ini saya belum menemukan konten seperti itu. Dan baiknya tanpa merusak part aslinya..
I know it’s too late now (this video only came up today & it looks like I’ve been unsubscribed) but could you not have made bevel gears? This way you could have used the crankshaft and had the motor mounted vertically, which I’d imagine would make it more efficient plus better balanced?
Don't make your own gears! They're likely a metric 'module' gear, available off the shelf just measure carefully.
(edit) Fair play you made your own gears 😂
This is a cool project!
So cool. Your machining skills has gotten so good. your earlier videos and now Your skills has improved so much. I'm wondering, instead of making the actual part, could you have made a Sprocket cutter that you where missing to make the part instead?
