Today we drive the rotary shifter go cart on the street! 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 running and driving again we had to do some serious research to find out how to get the clutch working again. This kart is also rocking the 787b Renown livery of the 1991 Le Mans car. While it doesn't seem like much, it took us hours to get everything up to spec. After it was ready to go, we took it out to some abandoned roads and really let it get up to speed! It was definitely the fastest thing that we have ever driven or created so we were blown away by letting it loose! Thanks for watching and be sure to stay tuned for some more ripping this thing! (top speed video coming very soon!)

We're back with the rotary! Thank you guys so much girls help. We work. The rotary was down for a long time, that's kind of why we finished up some of the turbo series, but we are back this little. Six.

Millimeter ball is going to be our solution. We are not for sure, because we couldn't find the exact parts diagram, but there's some KTM motorcycles with very similar clutch designs that had this bearing ball, and thanks to you guys in the comment to the last video, we were able to figure that out. So really it's just as simple as putting this in in between both levers and seeing if it actually works, so we'll install it. Now I put a ton of grease in there, so hopefully it keeps it from shredding itself like before.

Okay, people about two hours later I got all those bolts tightened down and yeah just hit it. A couple of times works. That's a functional clutch, so it looks like the six millimeter ball was a good solution. I don't really trust it yet, but it's the brake repeat so now it's time to just put it back together and send it okay, so we have the transmission all buttoned up.

So at this point, we're gon na just cross our fingers and really hope that it all works out. So now, what we're doing is we just kind of throw the chain on and just read, look up some of our linkages and then we can get to driving this thing all right, so we're out here at her favorite filming location, we've got the rotary out here. Hopefully the rotary reliability doesn't come to bite us again. Cuz we got the clutch fix.

It's running pretty good, since it's kind of hard to push Dart got the c10 bike out here and we're just going to try and pull started. So, let's get started now. Was it sane like five times that was crazy, sorry, tar.gz quality muffler? Unfortunately, the router is a pretty good torture test for that bad boy. Alright guys this thing isn't saying the rotary experience is definitely a unique one and I wasn't even giving it that much gas, but it was just super fun just to have this thing.

Besides you screaming without a muffler, it's borderline unshriven, it's like ear piercing look out, but it was still tons of fun even just putting around. I just don't need to get used to this thing. It's my first time driving it, but you can definitely tell it's a different animal, alright guys thanks for watching this thing is an absolute blast to drive around super insane. Definitely probably the fastest thing we've built so far yeah and we could not be here without your guys's help by the end of the last video we were so down so upset that the clutch was all gone.

We had no guidance, no parts manuals, but with your got y'all's help we had a lot of German subscribers translate and find his parts manuals. We were able to look a couple up that was really really cool, seeing like the whole community come together, but anyways like joe said earlier. This thing is ear: piercing, there's nothing wrong with DG mufflers. It's just the fact that this thing is so hot.
I don't think we can run anything aluminium on it. It actually melted at the seam. So, like literally a tour through the aluminum yeah, the original Hercules bikes have like a double sheathed exhaust cuz. It would get cherry red yeah.

So with that being said, I'm glad you got to hear straight pipe. That was awesome, although it was pretty loud, maybe too loud to drive. So if you like this thing, if you like the 787, be right lively if you are livery, if you're a rotary fan, you should definitely subscribe to us because we're doing a top speed video soon and we have another rotary on the back burner.

    ANY intro music shite that is longer than 10 seconds is a total down vote on youtube !!!. you are NOT CNN etc. 5 seconds would be better than 10 seconds of stupid fucking music and shite graphics would be even better. After the totally shite intro the rest is simply not worth watching as anyone who offers that crap is simply a moron. what a shame, it COULD have been interesting, but, you ruined it at the first hurdle. Typical fucking yank.

  8. Avataaar/Circle Created with python_avatars Piloto Hernandez says:

    Sound great but if you get hard time to turn on maybe need new seals

    Sounds like it's running better without the muffler rotary engines hate exhaust restrictions and the throw back livery is awsome I remember watchingthe 787 and 787b race on tv when I was younger

  12. Avataaar/Circle Created with python_avatars SMART ASSIST says:

    My goodness! I am happy but holding breath….. wonder what top speed was?

    That scar intro music though only cultured people will get it

  15. Avataaar/Circle Created with python_avatars harley pickin says:

    Anyone know where to get this type of rotary and gearbox?

  16. Avataaar/Circle Created with python_avatars Patchouli says:

    Man the 787B livery sells it. Never thought I'd see the day of a dorito-powered go kart, but here we are.

  17. Avataaar/Circle Created with python_avatars J GILLY says:

    Yo be a G and do me a favour and let me know we're imma get everything in the UK for this project including tools or can I buy em in UK straight up

  18. Avataaar/Circle Created with python_avatars Edward Dergosits says:

    Awesome build!! I have owned 3 rotary powered RX cars. These engines rock!

  19. Avataaar/Circle Created with python_avatars Flippie De Bruyn says:

    Not the rotary that's giving problems rather the gearbox! so rotary Reliability is irrelevant.

  20. Avataaar/Circle Created with python_avatars Ryan Braganza says:

    Love it!!! And also love the fact that you coloured it green and red to pay homage to the legendary mazda 787B!!!…….

  21. Avataaar/Circle Created with python_avatars Labbzy says:

    this kart is realy cool! love karts with big or od engines 😀 I have a smc f-kart "road legal gokart" with a 1960s ish husqvarna 250 twostroke engine with around 40hp 😀

  22. Avataaar/Circle Created with python_avatars drift_ boi says:

    A four stroke that sounds like a two stroke… The meaning of life has been found

  23. Avataaar/Circle Created with python_avatars Pablo Jones says:

    The helmet footage made it sound like a kazoo!🤣 great work though.

  24. Avataaar/Circle Created with python_avatars Clifton Manley says:

    it didn't RIIIP, Rotarys are supposed to RIIIIP as stated elsewhere, undergeared is the first thing to fix. Air box, proper exhaust, Rotary engines very susceptible to seal burn out. Put porcelain seals in it when you blow it up. lol

  25. Avataaar/Circle Created with python_avatars Clifton Manley says:

    Rotary engine cars and bikes need a stainless exhaust or it meltssssss………… lol I never did understand the attraction and I've seen every type of

    rotary engined vehicle you can imagine, although this is the first kart… nice job getting it running at all.

  26. Avataaar/Circle Created with python_avatars BLK DNA says:

    Sounds ozom wooooha!Crazy rotary kart.The straight pipe is quite ozom.

  27. Avataaar/Circle Created with python_avatars Alexandertheaverage says:

    Mean 80z intro. Very karate kid. Why no skids though ????? Come on

  28. Avataaar/Circle Created with python_avatars Build Break Repeat says:

    We did it y’all! Thanks for your help! Definitely subscribe because we didn’t even hit 5th gear in this vid and we plan on topping this thing out in the next one!
