I can't begin to thank you enough for this video. There are a ton of great MX650 modification videos out there that have plenty of detail in them that inspired me to get a 650 in the first place, but this is the first one that actual shows all the steps that other videos do off screen and then just tell you how to do. The fact that you actually showed how to recess the screws in the motor other than just saying you can do that, has been something I have been searching for and dreading to go in relatively blindly. That part is an absolute necessity that someone trying to become handy, like myself, needs to feel comfortable with potentially ruining their Razor lol. Thanks again for the guide and confidence boost. I can finally put the motor I have sitting around in my MX650 with some comfort.
Thanks for taking the time to comment man, it’s people like you that inspire me to keep putting out videos. Let me know if you have any trouble putting that motor in the bike. They are a ton of fun once they go twice as fast.
@@MarleyJaxGarage I definitely will. Already saved them to watch later. I have an MX650 and a PR200 for my kids and plan to get a couple more as projects. Keep up the great content!
BEST MOST COMPLETE AND LOGICAL 650MX UPGRADE I HAVE EVER SAW, I UPGRADED ONE LONG BEFORE ANY VIDEOS WERE OUT, YOU HAD THE SAME ISSUES AS I DID WITH THE SAME PROCEDURES AND THOUGHT PATTERN, SUPER JOB. I WOULD HIRE YOU.
Great video, man! I agree, lots of partial how-to videos. This is the first top-to bottom, stock to modded video i've seen. Been looking into doing something like this for a while now, thanks for the instruction!
Thanks man, that is great feedback. You should definitely build one of these and let me know if you have any questions. Comments like these keep me motivated to put out more videos.
This is what gets people popular man I've built my first one with this video and sold it and I built a 2nd one with a lil help of this video and a 3rd one which no help outher than that damn side panel lol the on off swich but with the help of the video I got it apriciate it champ
Thanks man I remember you commenting a couple months back. Glad you got everything figured out and can build these now. People sell these for big money around me.
As a guy who learns best by watching once and jumping right in, your videos are perfect! I'm out here tearing into my first of two mx650s. This is all I needed to see! 🤌
Thank you for all the MX650 upgrade videos! I just got it along with all the upgrades parts (1800w motor, bigger spring, lights,..) and planning to do it soon thank to you again 😀. Also got 2 mx350 for my kids and planning to used the 650w motor for the mx350. If anyone here in LA area, please let me know if you willing to sell your original motor set: 650w motor, controller and throttle (need cheap extra set)
Doing this build now!Appreciate the video it helped out!Already pre-assembled my motor and connection then all I have to do is connect the battery when it arrives tomorrow!
@@MarleyJaxGarage For sure I got it all hooked it up and it works...Just one question though I do not have a 3 speed and i have it jumped.I saw you said put it in the middle then high speed wire and i tried the left and right side.Would ether one of those sides be the high speed or will you also have to remove the middle also and just left and right only?Reason being i did test on both amd max speed i got was 22mph on flat.Thanks for the reply!
I would just take a piece of wire and strip the ends and poke them in the connector to test it. It should stay in place itself, but the best way is to put one end in the middle pin; get someone to lift the motor wheel and give it full throttle, while you touch the other end of the wire to the high-speed pin, so that you can see/hear the difference.
@@MarleyJaxGarage gotcha that’s exactly what I did.So you’re saying one end has to stay in the middle correct on the 3 speed.Then the other end in ether or (which ever is fastest) correct?
Great video and detail. Best video I have come across for modding the razor sx500. I’m buying all the parts to mod it rn. Thanks for the great tutorial I really appreciate it!!
Awesome video! I picked up the same kit for my MX650 and once throttle and wiring was hooked up, i realized I couldnt turn it on by switch or key. Might need to watch the e-lock and on/off switch again, but think I might have found my solution. Ty!
Got a free MX650 from a neighbor it need full rebuild, about to order a kunray 48v 45A kit with motor 3 speed keyed volt meter throttle, gonna look for that same branded battery
one option instead of modifying the motor screws is just use a hacksaw and cut the heads off the screws so they are flush with the motor. however only do it if you sure you will never ever need to remove those screws
I get about 90 minutes of mixed riding with this setup. The weight of the rider and the terrain make a big difference in battery life. I am about 200 pounds for reference.
ive been trying to upgrade my bike but have little to 0 of the tools i need. I feel so defeated not bieng able to find a detailed but easy tutorial that works for me.
I would see if you can borrow some tools. There are many people out there willing to lend a hand and this project just needs basic tools. I am always helping out neighbors so don’t be afraid to ask around. Start small and buy when you can afford and need the tools, that’s how I got all my stuff. I buy used from marketplace and yardsales.
Awesome! I'm trying to do the same thing with my daughter's 650.. do you have a list of everything that you bought to complete the upgrade. This is one of the best tourtorials I've seen. Great job!
They must wire up those switches different now in the throttle. Followed your instructions to the t but decided to go ahead and hard wire speed switch and volt meter on the throttle. I have 1 as medium 2 as fast and 3 as slow. It's all good though. It works and that's all that matters. I don't have a piece of wood to mount the controller on. I noticed if you place the heat sink inside the right hand side of the box that it fits nice and tight. Just wondering what i should do to mount it. Thinking about some sticky velcro, or drilling into the side of it and mounting it directly on to the case
Im having the same problem as many here. I went with the exact items liated in the description. Everything wired the same but used throttle that came In the kit rather than the 3 speed. Wired the two elock wires together. Tried every combo of 3 speed wires together. Power is going from the battery to the controller but No response when throttle is turned.....😢 I'm lost. Not sure If I recieved a bad controller or motor?
I recommend using a 3 speed throttle since it is a 3 speed controller. I never used the throttle and it seems more people have trouble with them. Haven’t seen any comments about issues with the throttle in the description.
Do you think you can make a video on the side Panel and show how to do the wiring bc when I was watching the video whatever you used to wire it up it wasn’t on the link for the parts and wires. So if you can can you make a vid on showing what you need for the side panel and the wires you need for it and how to do it that would be great.
@@adamomidvar4519 Lowes/Home Depot or pretty much any home improvement or auto parts store will have the wire in there electrical section. They will also sell all the connectors needed as well. I don’t remember where I got that particular wire from.
Hello I just wanted to say thank you so much for the upgrade tutorial. I’m good on everything but I’m just a bit confused on connecting the battery and controller to the original plastic where you would charge the bike from stock?
i followed along for the whole video minus using your 3 speed throttle. i’m totally stumped. Everything seems to be reading voltage. but when i turn of battery and twist throttle i get NOTHING. been trying to figure out for a couple days now. Hope someone can give me some insight
Read through the comments, a lot of people had been wiring up the 3 speed differently but that it most likely your issue. The only other common problem is an issue with the brake controllers but you could unplug to test that
Ok I have the exact setup and wonder - when you cut and spliced the brake wires on the controller to put the original controller connectors on, which wire did you put to red and which to black?
How was the torque compared to the stock motor .I ride in the woods on mine with small hills . The stock motor with 48 over volt don’t like to pull the small hills that great.
It has way more torque than stock, not really even a comparison. It does pretty good on hills with people 200lbs and lower. It will kill the battery faster but the new motor is 1800 watts vs stock 650 watts
I built this to ride in places that don’t allow gas powered vehicles. The battery upgrade is decent but if your going through all that trouble might as well get the motor/controller setup instead of just over volting the old components. I own gas dirt bikes as well and they all have there time and place.
Can I use the motor alone with my own speed control knob and plug it in? Will it work? I don’t need those other parts. I’m using it for a different project.
Good Video alot of info, I have question, If my battery has its own switch (Ebike battery) can i make a different switch? I want to put my covers back on but need way to turn off and on... (I do have a key also but battery still is on)
You don’t need the junction box it just makes the connections easier. Most of the eBay motors already come with controllers so you wouldn’t be saving much money.
When I had everything set up I plugged in the last two cables to the battery and the on switch and I heard a pop and then nothing worked I turned on and off switch and nothing
Sounds like you might have wired something up backwards and blown the controller. Did you wire everything exactly as shown in the video? Is it the same motor controller setup I bought? Check and see if the inline fuse is blown.
Do I need a three speed throttle? I bought all the stuff and realized I missed the throttle so just wondering if I can still make the build, or need to buy the throttle
I'm confused with what you did with old powerport. What is the elock your referring to? Did you remove the stock power port. I did and I plan on keeping stock on/off switch. I planed to use the old power port hole to put new port that is attached to battery. I don't have use for that stock port and don't want to drill any unnecessary holes. Just trying to figure out what the elock is that your referring to. Sorry I'm new to all this and have the same set up you have.
I used the stock on off switch to control the main power between the battery and the motor. The e-lock is used as a key or switch when there is power to the controller. If you do not want to wire it up simply connect the two e-lock wires together. I used the old charging port for the e-lock and then drilled a hole lower down where the charging port for the battery could stick through.
Sadly I tried doing this and it failed to work. I then ordered the same kit again to see if it was because of a malfunction from shipping and the second kit also did not work. Now I'm stuck with a kit that I'm returning and a kit that is no longer returnable. Not sure what to do but thank for the video!
What exactly is going on? I’m guessing you are just missing some of the wiring if it won’t turn on at all. Read through the comments on here and there is a bunch of troubleshooting information. I’m sure you can get it figured out, just need to narrow it down. I have seen a couple good wiring diagrams as well.
@@MarleyJaxGarage It turns on and everything works except the motor doesn't spin. Not sure exactly why but when he hooked up the battery to a different power switch on the razor than the regular one, what is that switch?
Not working for us. bought the controller kit and the battery right from these links. Didn't do the three speed, that throttle with voltmeter, or the elock, just what came with the kit. It wasn't too difficult following your steps to hook it all up. Got it all wired up, turned on the switch - nothing. Then I took the switch out of the loop and wired the black/red from the battery straight into the controller - nothing. All we have connected are the brake wires, the blue, green, and yellow wires, the one pin connector that plugged straight in, the throttle, and the power. Any help would be appreciated in troubleshooting as there could be any number of things wrong (bad motor, bad controller, bad throttle). the controller is a black box, so no way to know what is going on inside, but if there is a way to troubleshoot that I'd love to hear. thanks
You need to finish wiring it up. It will not work unless you wire the e lock together if your not going to use it. You will also need to wire two of the 3 speed wires together. You can look up schematics for these controllers and see exactly what they need to turn on.
That is part of the plan for this build. I have an upgraded suspension on the way with a few other things. Hoping to get a video out on it when they arrive. Thanks for watching.
Thank you. I have not bought any 36v batteries only 48v. My battery has been good so you can probably go on eBay and get one from the same manufacturer. Link is in the description.
So I am running into an issue I can't figure out. My motor is not powering on. Also my throttle voltage meter is not displaying anything. I have verified there is voltage up until the last connection going into the controller. It seems no power is coming out of the controller though. I would think it is a bad controller, but I already returned a controller and motor set due to this same problem. The only thing I can think of is some wiring issue. I can't add pictures so it is hard to show my setup. I have followed your instructions pretty closely. One thing I have noticed that is different is on my mx640 is the on/off switch is wired a bit different. This is the section coming from the battery to the switch in the side plastic and then to the controller box. This section includes the online fuse. There is a red and black wired but there is also a third smaller red wire. I am not sure what this is for.
You can send pictures to my email linked in the description if you want me to check it out. The little red wire on the side case is part of the old charging system. It provided voltage to the controller when it was being charged so you couldn’t drive it with the charger connected.
So I took a half hour and read through all the comments below and I think I found my problem. I believe I have to wire my e-lock wires together to get the controller to turn on. I thought using the e-lock wiring was optional, but it seems like if you don't wire it to a switch, then you need to connect the wires together to keep the controller always in an "on" position. I am hoping this is the fix I was looking for. I am planning on using a 40 amp fuse too. My battery has a max continuous output of 40 amps but the Controller is only 34 amps. I know there is the potential of burning the controller box, but I am wondering about the wiring. It looks like the stock wiring for the switch..etc. is 10 gauge which is rated at 30 amps. Is there a high potential of melting the wire by using a 40 amp fuse instead of 30?
I have heard of people just over-volting the controller and motor but I have never tried it. My guess is that it might be a little bit faster but not much. I don’t think it will fry the motor.
Really? That’s crazy expensive. They go for brand new on Amazon for $650 in the States. I find pretty much all of my projects on FB Marketplace. These come up all the time with dead batteries for pretty cheap.
@@MarleyJaxGarage really? What is the go with the batteries are the rubbish? Are they expensive to replace? What do you think it would cost to ship something like that to Australia? Honestly mate if you started an amazon page selling them to Australia I think you would sell a few.. I for one would buy 2 immediately
Would it be fine if I run a 72v 3000w kit with 48v 20ah battery? That way if I ever want to upgrade to a 72v battery later, I don’t have change out the motor and controller.

No I set it up to charge with the port that comes with the battery.

Sounds like you might have wired something up backwards and blown the controller. Did you wire everything exactly as shown in the video? Is it the same motor controller setup I bought? Check and see if the inline fuse is blown.
If I have a 48 volt battery do I need a motor that has a certain amount of watts?
Watts = volts x amps. So yes you need to get the proper configurations.
do you 100% need everything in the description or can i not but the extra throttle and just use the throttle that comes with the motor and controller?
No you can just wire 2 of the 3 speed wires together just need to figure out which one makes it run the fastest.
Did you notice any issues with your battery rated only upto 1500w but your motor supposedly drawing 1800w?
Same question. Thanks
would it work if i got anew battery and mottor but the same control box?
Not sure but usually the motors come with controllers if you get them off eBay.
Do I need a three speed throttle? I bought all the stuff and realized I missed the throttle so just wondering if I can still make the build, or need to buy the throttle
I'm confused with what you did with old powerport. What is the elock your referring to? Did you remove the stock power port. I did and I plan on keeping stock on/off switch. I planed to use the old power port hole to put new port that is attached to battery. I don't have use for that stock port and don't want to drill any unnecessary holes. Just trying to figure out what the elock is that your referring to. Sorry I'm new to all this and have the same set up you have.
I used the stock on off switch to control the main power between the battery and the motor. The e-lock is used as a key or switch when there is power to the controller. If you do not want to wire it up simply connect the two e-lock wires together. I used the old charging port for the e-lock and then drilled a hole lower down where the charging port for the battery could stick through.
@@MarleyJaxGarage how is it still running has it been good to you. Have you had to change motor or still running strong.
what wire did use to connect the power button. the long lead blue wire. i need that
Hey I know this was 2 years ago but will a 2000w motor work too?
do you only need one battery
Does the fuse box come with the bike originally or did you have to buy it separately
How did you do the electric start I can’t do it
Sadly I tried doing this and it failed to work. I then ordered the same kit again to see if it was because of a malfunction from shipping and the second kit also did not work. Now I'm stuck with a kit that I'm returning and a kit that is no longer returnable. Not sure what to do but thank for the video!
What exactly is going on? I’m guessing you are just missing some of the wiring if it won’t turn on at all. Read through the comments on here and there is a bunch of troubleshooting information. I’m sure you can get it figured out, just need to narrow it down. I have seen a couple good wiring diagrams as well.
@@MarleyJaxGarage It turns on and everything works except the motor doesn't spin. Not sure exactly why but when he hooked up the battery to a different power switch on the razor than the regular one, what is that switch?
@@gyattalicious1 you need to hook up the main power as well as wire up a switch for the e-lock. Without those wires being connected it wont turn on.
Ahhh! So if I’m not using the e-lock wires at all then it won’t turn on?
What battery’s is that and how much range do u get
Not working for us. bought the controller kit and the battery right from these links. Didn't do the three speed, that throttle with voltmeter, or the elock, just what came with the kit. It wasn't too difficult following your steps to hook it all up. Got it all wired up, turned on the switch - nothing. Then I took the switch out of the loop and wired the black/red from the battery straight into the controller - nothing. All we have connected are the brake wires, the blue, green, and yellow wires, the one pin connector that plugged straight in, the throttle, and the power. Any help would be appreciated in troubleshooting as there could be any number of things wrong (bad motor, bad controller, bad throttle). the controller is a black box, so no way to know what is going on inside, but if there is a way to troubleshoot that I'd love to hear. thanks
You need to finish wiring it up. It will not work unless you wire the e lock together if your not going to use it. You will also need to wire two of the 3 speed wires together. You can look up schematics for these controllers and see exactly what they need to turn on.
@@MarleyJaxGarage I found that info later in the comments. Did that and it worked! Thanks. It was not knowing about the controller that was the pain.
get a 'DNM" 165mm coil shock on the back. much much much better shock. they swap right in and can even add some height.
That is part of the plan for this build. I have an upgraded suspension on the way with a few other things. Hoping to get a video out on it when they arrive. Thanks for watching.
Do you have a link to the one you bought?
the 30amp fuse wire that comes separate on Amazon correct
Great video. Thanks!
Can you recommend a good 36v 20ah Li-ion battery?
Thank you. I have not bought any 36v batteries only 48v. My battery has been good so you can probably go on eBay and get one from the same manufacturer. Link is in the description.
Thank you! Do you leave the battery charging overnight or it's not safe?
@@ddpmusic I try not to do that but I have left it charging overnight a few times without any issues.
why did you need to counter sink the screw holes? just wondering as im waiting on the bike to get here to throw my 80v battery/3000w motor on it lol
They were hitting the rear swing arm and would not mount up correctly without counter sinking them.
@@MarleyJaxGarage thanks!
Do you know how fast it will go
So I am running into an issue I can't figure out. My motor is not powering on. Also my throttle voltage meter is not displaying anything. I have verified there is voltage up until the last connection going into the controller. It seems no power is coming out of the controller though. I would think it is a bad controller, but I already returned a controller and motor set due to this same problem.
The only thing I can think of is some wiring issue. I can't add pictures so it is hard to show my setup. I have followed your instructions pretty closely. One thing I have noticed that is different is on my mx640 is the on/off switch is wired a bit different. This is the section coming from the battery to the switch in the side plastic and then to the controller box. This section includes the online fuse. There is a red and black wired but there is also a third smaller red wire. I am not sure what this is for.
You can send pictures to my email linked in the description if you want me to check it out. The little red wire on the side case is part of the old charging system. It provided voltage to the controller when it was being charged so you couldn’t drive it with the charger connected.
So I took a half hour and read through all the comments below and I think I found my problem. I believe I have to wire my e-lock wires together to get the controller to turn on. I thought using the e-lock wiring was optional, but it seems like if you don't wire it to a switch, then you need to connect the wires together to keep the controller always in an "on" position. I am hoping this is the fix I was looking for.
I am planning on using a 40 amp fuse too. My battery has a max continuous output of 40 amps but the Controller is only 34 amps. I know there is the potential of burning the controller box, but I am wondering about the wiring. It looks like the stock wiring for the switch..etc. is 10 gauge which is rated at 30 amps. Is there a high potential of melting the wire by using a 40 amp fuse instead of 30?
What is the AWG of that adapter that you used for the battery
God bless you 🙏
Thanks for watching.
Can you send a link to all of the connectors that you used? I know you said bullet connectors but I didn’t catch the names of the other ones?
I just got a big set of connectors on Amazon. The 2 pin connectors I used are linked in the description.
@@MarleyJaxGarage Thank you for the response.. much appreciated! Thank you for taking the time to make these videos!
How can l do so and keep the kill switch on the brakes?
If you plug the brake connectors in like I did than it will work just like before.
Can you do this but keep the stock motor? or will the extra voltage fry the motor
I have heard of people just over-volting the controller and motor but I have never tried it. My guess is that it might be a little bit faster but not much. I don’t think it will fry the motor.
Bro where do you get these things I can’t see anywhere here in Australia that sells them for under 2 thousand dollars
Really? That’s crazy expensive. They go for brand new on Amazon for $650 in the States. I find pretty much all of my projects on FB Marketplace. These come up all the time with dead batteries for pretty cheap.
@@MarleyJaxGarage really? What is the go with the batteries are the rubbish? Are they expensive to replace? What do you think it would cost to ship something like that to Australia? Honestly mate if you started an amazon page selling them to Australia I think you would sell a few.. I for one would buy 2 immediately
Would it be fine if I run a 72v 3000w kit with 48v 20ah battery? That way if I ever want to upgrade to a 72v battery later, I don’t have change out the motor and controller.
I’m not sure, I would think so but you might want to message the company selling the kits to confirm.
48v battery will run on the stock controller
Did this need any soldering?
