Today the rotary moves under its own power for the first time! This rotary go kart is powered by a 1975 Hercules W2000 motorcycle and is a complete monster for this small go kart frame! In order to get this thing moving under its own power, we needed to add brakes, throttle, clutch, fuel system, battery box, ignition system, and a chain tensioner. While it doesn't seem like much, it took us hours to get everything working properly and doing its job. With this, towards the end of the video we were able to start this engine for the first time on the shifter kart frame and we are more than excited to get to ripping this thing!
Stay tuned for the next episode where we drive this thing for the first time!

Yeah, it's been a hard time to do it so, as can be, while this heart might look like it's pretty much ready to go, be completely done, there's still a lot of stuff left to do and are usually kind of the more time-consuming pieces of the build And that's going to include brakes battering boxes gas system. We have to do an electrically operated ignition system for this rotary motor. We need to run a clutch. We need to get the throttle all hooked up, so a lot of little things.

We also need to do a lot more frame reinforcement, as you guys remind us in the comments made out of chain tensioner, so this video is going to be getting to as much of that as possible. I would love time the clutch setup in the throttle, so we can at least do like a little rolling test drive just to see this thing move under its own power. So we have a lot of stuff to do a lot of really nice parts amount up. So I think it's our best bet to start with the ignition system in that gas.

That way, we can see this motor run on this frame. So let's get started so I just finished up the battery box. I didn't really like how it fit anywhere, so I had another bar here and I actually think it held the cemetery of the car a lot. This is made out of a go power, sports clutch cover and chain guard, so that came in really handy to make something look pretty smooth on the side here.

So now we're going to mount a gas tank. This is a go power. Foot tank, it's beveled! So your legs can fit on either side. So if I put that right up in here, it'll be super easy because the nuts are already imprinted into it.

So we say to Millie we're now gon na monarch oil. We have this pipe. That perfectly fits the koala right here, so there's kind of little section like that. There's your mouth, so we needed a brake pedal.

So I just cut this piece of metal and bent it to match kind of the general shape. Of these other pedals got a pedal. Second, they all line up really. Well, that's a tough news, though Germany, Ghana, that's the summer dude study abroad in the toy study abroad for about two months, but I'll be back in July's 50.

Then yeah we'll see you Joe okay. Well, now we're gon na get the shifter on we cut down the shift lever and I kind of run it out of it. We got our hole now, connect right to the tire lookee there I got a shifter see how it feels yeah, it's not very hard to get in now, yeah we're starting to stack a bunch of stuff up in here. Well, oh yeah, she's toasty! There we go.

Oh dude, that's me, it's pretty close to you can count me yeah. I think you feel just like up shifts yeah and it's nice, so we use a spindle right up in there. So it's gon na have very little side-to-side movement. It's just all forward or backward especially tell you everything go so we're gon na cut it to length, and I think we're going to put an eight ball and it just that one so yeah this is an actual height, so we'll patch in it trim it right.

At the height of the wheel, drill an eight ball and we'll be rockin yeah. How deep that is! Well cheese. Watch the camera. That's pretty good! Let's see alright guys.
This actually looks so cool. I mean you got. Ta have some kind of some random stuff, just lights up the build a little bit we're going to install it. I think that's really good hand.

Height super close to the wheel, he'll just feel like click it back like that, super easy, don't get it all bolted up. Then we'll move on to the next I made this bracket here. It looks really good kind of took. My time is right with beveled with the break.

This is super easy. It's just gon na go right on here. It's nice. As we get to reuse, a super nice will would Pat caliper should be able to lock up the brakes and pretty much any speed.

But this super thick metal is just going to get welded right here, that's great the clutch setup. I've got the cable in and we're having a little bit of problems. Oh yeah, so, okay, we got full throw-in and now you shift in the first yep. Wait! That's wrong clutches in and we're still spinning, even if you hold it, it won't give in.

We hooked it up to the chain to to test it. So what we're going to do is we're going to take off this side. Take a look at the clutch basket and see if the contact pads are furrows or something like that, so we're able to figure out these discs right now. The clutch is fully engaged, so here push the clutch it.

So our plates are good they're, not sticking to each other or anything. This clutch is actually very little wear it's awesome and what I did was I just put the ratchet on this and I turned it over the fan, not a lot of force at all. So you can see our clutch is working properly, so now hit it right now I can't overcome it, so I think you just need a little bit of force to get free because it's kind of goopy in there like there's a lot of old fluid. That kind of just got yeah, it feels goes up.

Yeah gummed up that's weird, but well throw the cover on there and we are back in business, remove it in the mouth, for the master cylinder and now, since our brake gun was way too short, and we have all the tools we're just gon na put in Some hard brake line so we're just banging this up right now and we'll just get this to go to billow this mount right here and what you done got it. These foot players come in there yeah, so we kind of did this out of inconvenience at first, but now it's actually really sick, yeah plenty more of our brakes like this actually thought I was gon na faint yeah. There we go, we are going that'll do right in able to get the rest off okay, so we've got the chain tensioner I'll weld it up. We got tons of adjustment, so we can do it every one with that and we got the fuel tank yeah.

So I think all we're gon na do is we're gon na run fuel on we're gon na try to use to go power. Sport pulse pump, so hopefully that can supply enough fuel to this thing. Yeah home stretch guys okay, so we got a throttle. Hooked up works real nice, so, along with that, we have all the fuel system done, got all the wiring yeah, okay, guys so we're going to do now is we're going to test our basically the pulse pump to see if, while it's running, if it gets enough Vacuum to like actually work it kind of works, sometimes when you're convenient, but it I don't have to just stop working a little bit figured out how the choke works.
We've got the throttle thick, so we cannot have as high as it with an oil. Let's go to shop alright, so we just got ta make sure that okay, we need. We didn't put that DG silencer on there yeah she's allowed as hell. This is that's law yeah, dude yeah! No, I mean that rolled forward.

How did it feel I mean? I was being super, slow and really careful, but the clutch felt like normal yeah, it's all our gon na any other clutch. Okay, it's pretty solid yeah. I think that's gon na about wrap this video up. I mean she's just about ready to drive now we're gon na do is we're tearing apart the entire thing, and then we need to do a lot of bracing, so we have taco this frame so sweet.

This thing is building up to be one of the coolest videos of us driving ever stay tuned next week should be the first driving video of this thing early Sunday. I want to see a good notification squad, so let's get it for the rotary anyways. Thank you. Go power sports pretty much! Everything is from this thing as on go power stores.

If you do get stuff from go power sports, that's on this car! Try to go through the links in the description that actually helps out a lot by submerged. We have some rotary power. Shirts that'll help us out a lot as well, and then we also just picked up a little spoiler. We picked up a 30 horsepower electric motor and all the batteries and stuff the guy was actually doing it for a motorcycle swap so with similar horse powers.

The electric versus gas versus, like it rotary that smokes a lot and stuff it'll be a good little rivalry. So stay tuned for that definitely subscribe. If you want to see some of that action, thanks for watching, see you next time.

    I'm loving the series also, it doesn't matter about looks it's about quality and efficiency! 😉 I'm also a nine year old who's really interested in Wankel rotary engines like the R26B Mazda 787B engine, which is my fave car, and y'all just inspiring me to build my own go karts and your building up my hope to become a race car driver! Keep it up!

  2. Avataaar/Circle Created with python_avatars Jose Morales says:

    Hi, where can I buy a engine like that one, please if someone know let me know

  3. Avataaar/Circle Created with python_avatars Russell Barnes says:

    Hey guys what's the intro music? It's friggin great!

  4. Avataaar/Circle Created with python_avatars Jesse Fex says:

    Rotaries get hot. Might want to add a shield between the driver and the engine. Just saying.
    I got a km24, runs hot

  5. Avataaar/Circle Created with python_avatars NeoIsrafil says:

    "Built of gopowersports clutch and chain guard" so you could say that gopowersports came in……….clutch? Lmao

  6. Avataaar/Circle Created with python_avatars 3V0 says:

    As much as i like the idea, and as cool as it really is, that kart is wayyyy too close together. making it wider wouldve given you more room to work with, and it would handle the speeds better, and it would drift easier.

  7. Avataaar/Circle Created with python_avatars Pedro Chavez says:

    This ain’t no go kart. This is a fully gutted FD! That’s been imported here🙏🏻

  8. Avataaar/Circle Created with python_avatars Patrick Ramsey says:

    You don't want the coil in that piece of pipe. It can make it hold heat and also transfers vibration and it's a big ground.

  9. Avataaar/Circle Created with python_avatars Melvin Yosten says:

    Always wanted one for a 4wheeler. But a gokart? Sooo cool

  10. Avataaar/Circle Created with python_avatars Dr1ver says:

    “Ready to rip”
    moves 10 inches under its own power

  11. Avataaar/Circle Created with python_avatars Luke Willmot says:

    The tensioner should be spring loaded so as under acceleration it gives a little and does not break

  12. Avataaar/Circle Created with python_avatars Andrew Halliday Music says:

    who's song is that intro saying " now i can fall in love" with the life you make me live" or something to that effect

  13. Avataaar/Circle Created with python_avatars James Exploring Online says:

    Im fairly certain those coils need to be able to dissipate heat, Setting up a smaller mount bracket may have beneficial results for the setup.
    Just a thought.

  14. Avataaar/Circle Created with python_avatars bigliftm says:

    guys you have no idear how RARE and valleuble that hercules wankel motor is… if you new you would put it in your bed next to you sleeping with a shotgun guarding it.

  15. Avataaar/Circle Created with python_avatars Bryan Roupe says:

    That's sick. What did the engine come off of ?

  16. Avataaar/Circle Created with python_avatars Dominique Dourneau says:

    Think my Rx use to rev up to 11000.. so easy does it

  17. Avataaar/Circle Created with python_avatars Dominique Dourneau says:

    Am an old guy..but you guys rock..and rotary is the bomb..

  18. Avataaar/Circle Created with python_avatars Siddhesh Mundhekar says:

    I was respect to rotary engine most powerful… but you gays making different, like that like from India 🇮🇳👌👍👍👍

  19. Avataaar/Circle Created with python_avatars Presscrete says:

    If you don't know who Ben Kelley is, who races off-road motorcycles, look him up, could be your twin brother.

  20. Avataaar/Circle Created with python_avatars Technie87' says:

    Is there a reason why most people go with steel to build their go carts? Im sure aluminum wouldn't be a whole lot more expensive yet a LOT lighter.

  21. Avataaar/Circle Created with python_avatars Matthew Chandler says:

    Speechless! I want to hear see and hear this completely wound out on track. Amazing!

  22. Avataaar/Circle Created with python_avatars Slicklickz says:

    I thought it was going to be a Rotary valve 2 stroke until I saw it.

  23. Avataaar/Circle Created with python_avatars Joe Kizonu says:

    If you get a chance hit Vasily custom builds. Dude could use some well wishes

  24. Avataaar/Circle Created with python_avatars Brian Rivera says:

    Welding the frame with all the weight on there? If there is any sag or stress you are welding them in permanently.
    I'm not saying it isnt square and flat but it's just good practice to weld without a load on the frame.
