I fab all day 5 days a week you gentle man are doing a fine job u could make a slick tensioner out of a skateboard wheel and one of those tiny gas shocks for holding open the back window on SUV never needs adjustment just a pivot point
I think if you use some of the Gopowersports little triangle gaucets to stiff the bearing holders on the "brake rotor" side, that would keep it from bending whenever you do any launches. Also, what about a "loop bar" that help you addding some strength to that "brake rotor" side and also work as a shield for any sudden turns
gussets. and yeah great idea, just ask for a chunk of 1/4 inch thick steel to a local metalworks shop, anything between 4 to 12 gauge and over 2x6, maybe 8 inches will do. gussets can run across and reach the other side. reinforcing the bar that holds the seat might be interesting too, since the torque in these areas has nothing but the chain/brake bearing tubes to travel on to the rest of the chassis. since karts are meant to flex forward towards the sides, and not side to side, it's not dumb to relieve the bearings a bit. finally, you guys have a bump steer problem to address. otherwise the kart will refuse to turn under braking or behave dangerously.
Just add a bar across the back to tie all the tubes in the rear together. To clear the brake rotor, you'll need only weld in another inch or so of tubing to what's there now. That'll look a lot cleaner and will also serve as a push bar/rear bumper. leaving the tubes open like that will otherwise make it look a bit unfinished.
Looking forward to this getting finished, hope you have some heat shielding between you and motor and as another person said some rubber mounts for the engine :)
Im doin a similar build with my bridgeported sachs km24 with keihin carb putting it on a tonykart race chassis. Will be a lot lighter and wont have to mod the frame as no gearbox just a race clutch. Will handle mint. Drifts on! Good work tho guys, im definitely watchin this space
Great work team, you guys are a huge inspiration. I have a sachs km48 rotary that im in the process of rebuilding but sadly lack of funds and a couple parts are holding me back, but I plan to do a similar build some day.
Looking good guys. I know you all didn't have a choice in the carts width or length but it looks almost as wide as it is long. I know most shifter carts do. Funky!😜

Put an adjustable idler sproket on the bottom/slack side of the chain. I would use a threaded type adjuster not spring loaded since it will see tension the other way when you downshift. Spring loaded will whip like crazy if you bang a downshift.
Did you guys get the turbo friendly version of the ecotrons kit. You know it needs the bigger injector and the 2.5 bar map sensor. If not you might have some tuning problems with the turbo and just that a small map sensor and injector.
You will need to have your axle so it can slide back and forwards for adjustment or on some kinda pivot point like the chinise quad bikes. Also a spring loaded chain tensioner. As you will be changing chains just about every ride
That looks absolutely terrific! I can't wait for the next episode. But, I'm really concerned that that engine case is a structural element, under stress from any tortion in the back of the frame. As much work as you've put in, would you please make an effort to isolate those forces. I mean, it might be better ratings if you don't. And, honestly I'm curious. So, nevermind. Let's see if it breaks and you can repeat it. But, all that work building the motor...
A center axle support might be a good idea too. Depending on the torque and surface it goes on. I know rotary engines aren’t exactly torque monsters, but this engine isn’t a 400cc general purpose thumper.
Sick video lover your stuff guys looking forward to the next part. Not trying to be a safety troll but you guys need to get some ear protection and a mask those grinding fumes going to cause you serious trouble in the long term ! Keep up the awesome content tho 👍
@nallen100 If you want to go faster on your ten speed, the rear derailleur puts the chain on a smaller sprocket. If the guys in the video put a sprocket on the rear with twice the number of teeth, it will take twice as long for the sprocket to go around, thus cutting the speed in half. Really hoping your pulling my leg here.
@nallen100 KK I'll try one more time, then if you still don't understand, then maybe try googling this stuff. Their cart has a 1:1 gear ratio, meaning every time the front sprocket turns once, the rear will also turn once. If they put a sprocket on the back with twice the teeth, Then it will make half a turn for every 1 turn of the front sprocket. This would be a 2:1 ratio, and would cut their speed in half while doubling their torque. Not really sure how I can make it much more simple.
THE sickest go cart project I've ever seen! Huge rotary fan, and longtime subscriber-watched and thumbs up every *Build Break Repeat* video, all you young guys have great potential and are going places, with a successful RUclips channel on your resumes! Your video editing skills are on point, best around really. May I ask which editing software and cameras you use? Have an excellent day.
@@BuildBreakRepeat I'm going to invest in that equipment then, I use a ZTE Blade Z Max as my cameras (2 of them) and Power Director Pro (Android Mobile App) 😂---so I have been wondering as I want to upgrade. Excellent channel thank you for the response.
I'd rather own a rotary shifter kart than any other shifter kart with a motor you think it'd be possible to put a 1 rotor 13b engine on a shifter kart?
I'm still waiting for you boys to turbo that rotary for shit's and giggles and to see the terror in your faces when you get on it and the turbo spools up
What sprocket ratio have you gone with? Rear sprocket seems way too small (think motorbike.. You have a few gears for more speed, don't need a 1:1 sprocket)

How should we paint this thing! Also, any good names?
Dorito dasher
Paint it a sexy shade or orange and call it the dorito dasher
What about a Nascar theme!
Renown livery
Paint it purple or yellow and name it after one of the Mario karts
Its gotta be the 787b renown livery
THIS
Yes!
Fuck yea
100%
best gokart build on youtube HANDS DOWN..., im tired of those dam 212s already ROTARY POWER!!!!!!!!!!!!
You could always add an idler pulley for chain adjustments :)
geoffreyjones2000 Yeah, we are thinking of adding one anyways to take out the slack
Search Amp Link chain adjuster

WHOA! It looks like a jet turbine on the side of your cart! Thats beast AF!!!
This thing's going to be insane. I can't wait to see what it can do.
Do a spring tensioner with an idler pulley to keep the chain somewhat tight
Awesome build guys! Its great seeing young fabricators nowadays.
The steering wheel is upside down, love the build. Rotaries need to be in more builds
It probably would benefit from some rear bracing to help prevent the tubes that are holding the axle in place from bending
Yeah we are thinking of putting a bar right under where the axle is
Just add a bar across the back to tie all the tubes in the rear together. To clear the brake rotor, you'll need only weld in another inch or so of tubing to what's there now. That'll look a lot cleaner and will also serve as a push bar/rear bumper. leaving the tubes open like that will otherwise make it look a bit unfinished.
Ready to see this beast running
Welds look nice guys. Coming from me that's saying a lot as I was a welder fabricator for over 25 years.
I love the front of that engine, it looks like you have some kind of jet engine on the kart
Love it! You guys are kickin' butt on the build! Cannot wait to see it run!
those welds are looking a bunch better than a few months ago!
sick build, will follow.
finally a gokart build i can enjoy
That bad boy will need a decorative rear plate with "Wide Load" on it. Lol
Love how the quality improved! Shoot for the stars!
Call it RX-3.5
What I do for an axle:
Go to metal store
Get 1 inch shaft
Go go machine shop
Get a key way put in
I think you will need a bigger rear sprocket, are you going for 200 mph.
I can't wait to see it rip!!!!
So cool ! Please polish the front of the motor that would be dope !
This is gonna make you guys famous I think
Wright William? I hope it gets big bro
Build Break Repeat yeah, you guys are smart, and you have awesome ideas for builds I don’t see how you couldn’t.
Brazil is LIKE!
Looking forward to this getting finished, hope you have some heat shielding between you and motor and as another person said some rubber mounts for the engine :)
Hell yeah Rotary Kart LOVE IT!

Why isn't this kid have more subscribers? This dude has real builds!
Great work team, you guys are a huge inspiration.
I have a sachs km48 rotary that im in the process of rebuilding but sadly lack of funds and a couple parts are holding me back, but I plan to do a similar build some day.
Looking good lads!
You need to gusset you bearing carriers otherwise they will bend under hard turning conditions. Gussets must be added.
Yes...they could use the scrap material they cut off from the original bearing hangers to fab up something similar.
Dont forget premix for the fuel so you burn up the Apex seals
Looking great.
Watching this build cause I really wanna hear that rotary engine fire up must be some crazy sound
Nice welds
Should add a spring chain tensioner if you are worried about it being to loose pulling the bottom of the chain down can't wait to see what u do next
Cannot Wait To See How That Go with Rotari Engine
Awesome job, ought to definitely not tip in a corner its sorta formula 1 wide (but dang it looks cool), be fun to see when it gets a rip.
great channel, great team together! God bless buddy's!
Hell yes this thing is amazing. Grate work guys
Looking good guys. I know you all didn't have a choice in the carts width or length but it looks almost as wide as it is long. I know most shifter carts do. Funky!😜
That engine looks like a turbine! Cool
Make sure you use a pre stretched race chain so that way you don't have to worry about chain stretch
Nice bro.
Oh, and ......AWESOME!
Looking good guys, can't wait to see it in action..... And Hi from the UK.
COOL RIDE GUYS! YOU SHOULD PAINT IT MIDNIGHT BLUE.
You're gonna want to bring them front tires in or you will have a wicked push.
Im doin a similar build with my bridgeported sachs km24 with keihin carb putting it on a tonykart race chassis. Will be a lot lighter and wont have to mod the frame as no gearbox just a race clutch. Will handle mint. Drifts on!
Wow! You guys have come a long way in a short span of time since I've commented on your last build. Keep up the good work!
Where's the turbo at?
Rotary power 😈😈😈

Little too wide but awesome. Would have mounted the engine a little lower myself. Keep it up.
This Gokart is so cool!!!
Are you concerned with chain stretch?
Your welds are beautiful, mind telling me what welder your using?
A center axle support might be a good idea too. Depending on the torque and surface it goes on. I know rotary engines aren’t exactly torque monsters, but this engine isn’t a 400cc general purpose thumper.
Isnt that a weak, thin axle?
Sick video lover your stuff guys looking forward to the next part. Not trying to be a safety troll but you guys need to get some ear protection and a mask those grinding fumes going to cause you serious trouble in the long term ! Keep up the awesome content tho 👍
Put a seperate chain tentioner on it.
Btw the best go carts out there
Get a chain roller for the chain cause it’s gonna stretch. Nice build 👍🏼
Keep up all the awesome content guys
Put a floor on it under the pedals so u accedentally dont get ur foot stuck.
You can run a chain tensioner so you don’t have to worry about slop in the chain when it stretches
Chain tensioner will help you adjust chain "snuggly" lol
Axle sprocket way too small. You plan doing 300mph?
@nallen100 Taller sprocket on the rear will decrease speed. Go look at your ten speed.
@nallen100 If you want to go faster on your ten speed, the rear derailleur puts the chain on a smaller sprocket. If the guys in the video put a sprocket on the rear with twice the number of teeth, it will take twice as long for the sprocket to go around, thus cutting the speed in half.

nallen100 you are an idiot and have absolutely no idea of what you are talking about on gearing.
Great job guys . You should use ear protectors though . Tinnitus is not nice .

Congrats on 90k
A chain tensioner might be a good idea as well, something along the thinking of a belt tensioner in a car
Subbed and Liked for rotary power :) hype to see where this goes boys
hey, what's the reason to make the engine not down as possible?
What happens when the chain stretches with all that power . Might need to add a tensioner to take out any slack.
Just wondering if the 1:1 sprocket ratio might be too high? What was the ratio on the bike it was in originally?
if you're worried about the chain getting loose you should add a chain tensioner
I'd rather own a rotary shifter kart than any other shifter kart with a motor you think it'd be possible to put a 1 rotor 13b engine on a shifter kart?
That rear sprocket is extremely small. What made you decide to go with that gear ratio? you could easily weld a chain tensioner to help with and slack
Y'all need to give us an update on the Turbo Kart! I wanna see what it'll do with the new live axle! And the beast of an engine...
Kartssource Yeah man it’s going good, we will be getting back to that build after we get the rotary driving.
You should put the side pods on
Also the same thing with the front tires raising happens to me on my rotax max crg kart when you lock the steering wheel fully its kinda annoying
But it doesn't affect performance
Hmmm... How do you adjust the chain tension? Spring loaded chain tensioner?
WTF? I'm seeing double. LOL!!!! Your videos are getting even better. Keep it up.
You guys should really slot the bolt holes for the motor mounts
Gonna go about 453 mph with that gear ratio
J’adore t video
He says he loves the video in french
Sachsonette Rotor-Shift X ;)
I'm still waiting for you boys to turbo that rotary for shit's and giggles and to see the terror in your faces when you get on it and the turbo spools up
what chassis did this engine come out of?
What sprocket ratio have you gone with? Rear sprocket seems way too small (think motorbike.. You have a few gears for more speed, don't need a 1:1 sprocket)
Cool
RotorKart. Just an idea for the drive chain maybe a tensioner of some sort.
