One of our most popular builds has returned! The Rotary shifter kart (powered by a Hercules W2000 wankel motor) had been in storage since the last video we did with it of hitting the top speed. The clutch had failed at the end of the video due to the clutch pushrod welding itself to the ball bearings and eating through the lever arm. We had found a hydraulic clutch on ebay for a Harley that had the same size diameter for the pushrod, and it ended up working better than we expected! We also changed the gearing to get us some better top speed!
Thanks for watching, stay safe and stay tuned for the next video!

The rotary just sounds so good in this application
There are only a few engines that sound good. Like this wankel and nitromethanol V8
@@qwertyximan no
@@iamincrediblystupidbut4364 no?
So true
Lmao glad to here I’m not the only one that thinks so
Someone there really needs to learn how to TIG weld for all those small delicate jobs. I think they wil have issue with the short throw of the clutch pedal, the need a master cylinder that matches the slave in volume.
Dan: "I think this will work."
It works.
Also Dan: " I never thought this would work."
Dan is a man of contradictions
Lmfao 🤣
This is definitely the sickest shifter cart on earth
Yeah I don’t think my old 250cc 2 stroke homemade kart could even top this thing
Most def
as a rotor head. I agree
What about the ducarty you think it'll hold up if it was working
@@andrewjohnson442 it would probably twist the chassis again unless they reinforced the frame a lot, would be a good contender tho
This is by far my favorite of y’all’s projects
Get in touch with the freedom factory. I'm sure they would love to see it too.
Bring extra tires. Massive burnouts required.
Great build guys... A Cleetus fella has a track, sir
Definitely take it to The Freedom Factory. There's tons of space there, and Jeremy is a go kart guy too, so maybe you could get a 3 way collab going with Cleetus and Faster Proms. 🤷♂️
@@Snugglez187 Oh dude Jeremy would nerd the hell out over this thing, I'd love to see that!!!
Dont use car oil in a motorcycle engine. Use motorcycle specific mptor oil. Car oils have additives that are to slippery for wet clutches. Its not good for the clutch in the long run. Even some synthetic motorcycle oils arent good for wet clutches. Use a regular motorcycle oil. Like honda gn4 10w40 as an example
That clutch bearing is cooking itself because you have tension on it when you're not using the clutch. Just like on a motorcycle you always have a little slack in the clutch lever.
?what's free play.... lol. Definitely get worn in fast on the tight side.
@@justinsolomon4427 if your cable is tight it will cook that bearing. Just like on a car the throw bearing has air gap to the clutch pressure plate when not depressed.
Correct, which will also possibly lead to failure of the clutch or friction plates
@@justinsolomon4427 100%.
Usually on a motorcycle if the clutch cable doesn’t have a tiny bit of slack your probably actually slipping the clutch even when you think it’s fully engaged
The engine seems like it's running a little too lean, with the missing and blue flames. Could put an O2 sensor mount in the exhaust before the muffler to get some mixture measurements as you tune the carb. Tuning a carb is just make changes and see if it's better or worst.
wouldn't flames out of the exhaust mean it's running rich? there's excess fuel that's not been burnt in the exhaust.
@@dereksumstad6746 The blue color is the concern for me. In a piston engine, a rich back fire has yellow in it. Now, I do know rotary exhaust temps are way higher than piston engine...so maybe a rotary running rich is Blue and not yellowish. We tune 2 strokes carbs by soldering the jet closed and drilling few to the next size bigger or smaller till it 'felt' better. Just my 2 cents.
whoaah all that flamespitting and rotary noises are just too awesome, guys!
Yeah, dudes, reach out to Cleetus McFarland- he has an oval track he calls the Freedom Factory for a playground in Florida. Good weather this time of year! Hope your class scheds will flex- know even college has been a lot of "holding time " lately. Cleet should be finishing up a track resurface by now or will soon.
No
Y'all can get wayyyy higher in the rpms with that rotary
I was just thinking that it sounded like it wasn't getting to stretch it's legs
older rotaries are not that high revving than the newer ones
@@PHUSII that motor should hit peak power around 6000 rpm from factory they definitely aren't revving it hard enough
It hasnt been run in a while so just cleaning it out next vid we will see higher revs
@@shaynegadsden yup, it definitely has more in it, just waiting until they press that has pedal
If I see that Can-Am advertisement one more time im going to the nearest dealership and clogging their toilet
Do it
Do it
By far my favorite kart you guys have built, keep up the great work and keep building this kart better and better
if they are welding together you do not have enough play in the clutch lever they should only touch when the clutch peddle is pressed to disengage power the rest of the time they should not be touching the bearing
I remember when you guys had fun doing these projects. Feels more robotic these days.
Yeah, I was wondering what was off, this was it!
The new lavalier mics we've been using make it hard to talk excited without being too loud, still working on getting used to it. It'll probably get better with time
It would be good to take it to a go-kart circuit to see what it can really do. I love 787b's and go-karts so this is really cool.
The Vargas brothers over at Angel Motorsports need to tap and bridge port this thing
No
30HP never looked or SOUNDED so awesome.
My 14 year old son races a OTK ROK 125cc and it is very fast. I would love to see this rotary kart up against it. We run C12 and I am sure the rotary would be faster running this fuel as well. I know there is a lot more power that can be had from that rotary. I would love to see you guys continue to fine tune it for more power. The right carburation helps a lot also
Keep it, can't wait to see it on an air strip or big parking lot.
Its fun building stuff, the bad part is finding a place to let our projects run freely. East Texas here and no where to ride either.
That is just so Awesome!!'She's a Ripper'! I'd love to see you each get a couple 1/4 mile times.
you all have such amazing karts can I get one for $230 usd
The best rotary kart I ever seen, love the refresh !
I remember commenting on every rotary vid for yall to do the 787b livery lol
There is plenty of carting tracks you can take it to here in texas, the one in Winnsboro would definitely let you come out
The paint scheme even looks like a 787B. 😎👍badass
it sounds so happy with the regear
Not enough room to open it up to see the real speed.
LOL you never know what will work until you try! Nicely Done Guys!! I would suggest figuring out a metal spacer like maybe some Black Pipe cut to fit with a couple exhaust flanges welded on each end to keep it from flexing at all but other than that the Hydraulic cylinder you chose seems to work like a charm!! That thing RIPS!!
never clicked that fast in a long time 🤣👍
Ive been following since the beginning and love the rotary cart i think the most
Have to Look die an needle bearing Clutch Plate stuff...Happy searching 🙈
Take it to the Freedom factory
Heck ya this is so awesome I have got to get one of my hands on those little engines to cool
We are all here just to see it shoot flames
It sounds like the gatling gun of the A10 thunderbolt. EPIC.
Wow it’s sounds amazing
I think turboing the rotary shifter cart would be amazing.
Did you give up on the electric kart? Is that the reason for "reruns"?
Nah, it’s just more work then we thought. Waiting on a new motor controller. We’re gona upgrade to 500 amp, vids coming soon!
Never saw a go kart spit fire before
I hope you guys get a TIG welder soon. The work adapting that hydraulic fitting was really creative and it was amazing you got it done with a MIG. Another great one.
Yep, working on picking one up and learning! thanks for watching
Joe shoulda worn new shoes for his clutch close up 😳
One of the apex seals may be going bad. It shouldn't spark like that. Only flame.
it's probably the packing in the exhaust.
@@pierre-lucdoiron1325 or that.
Did they ever rebuild the engine with new apex seals? Looks and sounds good to me as he is accelerating
Lots of compression
I love this kart. I think I cheered when it push started. What muffler you guys running on it?
We're running this one from Amazon: www.amazon.com/Motorcycle-Universal-Hexagon-Exhaust-Motorbike/dp/B07SFFCLXG/ref=sr_1_1?dchild=1&keywords=hexagon+muffler&qid=1611112938&sr=8-1
@@BuildBreakRepeat thanks guys!
Yay, the kart that got me to sub to the channel!
It was really fun watching this project come together. The asymmetrical design makes me think of the STP turbine car driven by Parnelli Jones at the 1967 Indy 500. I hope you find somewhere this cart can stretch its legs.
My favorite build from you guys!!!!!!
Wow that low raspy sound 💜
Oh yes, i love this thing, nice job of you guys, i love rotary engines, this is something different for a gocart
As soon as I saw rotary I hit the video😂 I LOVE ROTARYS
Buena maquina 👌
Gotta love the livery
Your friction welding the ball bearings so they are constantly in contact, this is incorrect they should not be in contact under pressure long enough to weld, only when the clutch is depressed.If you set up the clutch to have free play as it should be (on all cable clutches) you will not get these problems plus you will not get slip and /or wear. I know I run this engine in my Hercules W2000 Good work though guys,love that brap brap.
Heck ya it’s going to rip with that bigger sprocket
Alright y'all earned a sub...however I I didn't know snowmobiles had a transmission.
Call Cletus MacFarlane at the freedom factory. I’m sure he’ll let you rip it. 👍🏻👍🏻👍🏻👍🏻
How far are you from the Dallas Karting Complex? They allow owner karts to race. All you dudes, Nothin' but Love!! I'm an old guy who likes to race Arrive and Drive karts for fun. Good to see some gear heads still exist. Cheers. How much to rewire a 1966 Ford F-100 with a 352 V-8?
Will the electric kart ever return with a better gear ratio
Isn't there a gokart track that has some pretty open space in Dallas Fort worth area?
Dallas Karting Complex in Caddo Mills, TX about 1 hour East of Dallas.
We have a track membership nearby, they just don't allow crazy shifter karts. We've brought 2 stroke karts there and we'll be bringing our electric gokart there soon
I was talking with my brothar about rotary engine on a motorsport chassis Kart-Car. I said to him: -Man...I'm gonna look in TH-cam to see if somebody has already done it. Oh, boy... I respect you!
As I said before I owned the bike back in the day and I think if I remember right, the listed top speed was either 80 or 85 (90 maybe...I don't remember). All I know is that try as I might I could never get the damn thing over 78 mph. I'd like to find another bike if I could. Or, even just the engine like you guys did and put it on a different bike frame. My current bike is an '88 Honda Hawk GT.
Hello
I do not understand very well what you are saying because I am French, I would like to know if possible the following elements:
-Cylindered engine
-Approximate power
thx
Just here to remind you that rotary engines love turbos...
Stop touching OIL with your HANDS!
Why do these you tube mechanics not know this???
I’m a bit disappointed with the clutch line. I did brakes with an lines for my go kart back in the day and used -3 an lines. I know there are banjo adapters since I did something similar to what y’all did, and I would’ve appreciated that extra quality.
That said, it works. If it ain’t broke, don’t fix it.
You boys would do well to learn how to use a damn angle grinder! Always blow the sparks generally towards, but not directly on yourself. This way when the grinder binds up, which it will eventually, it will pull the grinder AWAY from you. Those things can literally kill you...
Look up torrington bearings from a KTM. They use the same kind of hydraulic clutch setup with a rod.
You guys should build a shifter cart with a cr500 get ahold of cleetus mcfarland he has a great track I know he's in Florida but he probably wouldn't mind have you guys there
The Drag is to dangerous it blows up the tires. They get too hot on top speed. A good friend of mine has a rotary kart with 70 HP. It's hell to drive.
Okay... I used to play around on a custom built 250cc two stroke shifter kart and it was pretty insane. Can imagine this thing is off the hook fun.
I would use motorcycle oil that's JASO approved if you don't wanna burn up that clutch
Your steering wheel is upside down just saying 😬
Love wat you guys do, would love to see a turbo on there
That motor can rev up way more than that. You should give it some more beans. You are shifting at around 5000 to 6000 rpm but it can do more than that without breaking a sweat. Try going till about 8000 or 9000 before you shift.
Dallas kart racing facility is calling your name. Royce city DKC... Check it out!
What area yall in? The stunt bike community usually uses freight shipping yards after hours. Try finding a local stunt crew they will know alot of large open areas.
Ima simple man ,1. Get notified of a BBR vid 2. Click like 3. Watch vid 👍🏾😁
I know this comment is late to the game, but you should avoid using car oil in that thing - use motorcycle oil since it has the right friction modifiers in it. Car oil is too slick and it'll cause the clutch to burn out - ask me how I know. You need an oil that has the JASO certification.
Looks like an interesting build, what power is that engine putting out???
Im tempted to do something similar, i have a kz450 race tuned bike and a spare gokart chassie i think would create an awesome death machine. The only reason i havnt built it yet is because ive no idea wtf id drive it. If i did do that engine in a gokart though id definitely buy a vw camper totrod body ive seen on ebay as i think a mini sized vw bus with 70hp and gears would be awesome to race against a real sized one.
I'm not 100% sure, but the balls could be welded maybe because they were mounted the wrong order?? Other engines don't go in that way
finally i'm seeing some proper intro for the video, i straight up hated the previous one, just was wasting my time, thank you for changing that
I really enjoy the show but certainly could do without the insert of music it’s not necessary or Appreciated
The camera is always blurry, not very good for the video. But the kart is really cool.
should of mounted the clutch master cylinder on the frame in board and used a rod and linkage, the master cylinder and pipe will make a great crash bar.
Would a freecoaster style hub from a bmx help with the rear axle and rolling in neutral/clutch engaged
turbo it
You should do some more work on the exhaust pipe system, put 2 snails and 2 performance exhausts, then it will reach the real power
You can still rev higher bud . 9k rev's is possible. Nice work !!
maybe a side exhaust like the 787b its looks to me a great idea with the flames schooting from the exhaust
Ramy RC uses that same tune in his build video's... such a nice tune! (he builds rc planes)
Loving the "Renown" livery. Make it more true to the og for serious style points
All fun and games until that front end pushes on those cold tires and polished concrete. Good times though. Not much like a shifter
I think that engine will beat a highly modify honda gx200 or whatever
11:25 Is the kart dumped in 1st to start? Because it would be easier to start in 2nd or 3rd gear, and it would jerk as much put aside the driveline stress
13:04 Holy crap, this scene with the exaust flames in the end! And the noiseeee!!!
Race Jeremy from fasterproms shifter kart down the 1/4mile
did that rotary have gbox factory or have you made 1 to suite? the mate has a couple 1 in a gocart no gbox and 1 on a dirt bike
