I've built those engines and it has more than enough power for big buggies!! I can't imagine how that feels on that tiny kart?!? That is GNARLY!!! And yes, they are VERY loud lol
Piece of advice for anyone building a shop, build the absolute biggest you can afford because you will find a way to fill it up and you will want more space. We finally got a shop built a couple years ago and at the time I thought I was right at what I could afford budget wise. Afterwards I realized I could have afforded to go a little bigger and wish I had.
That looks like SO MUCH FUN! Also, good job keeping things neighborly with your neighbor. Whether or not he had a right to be upset, kudos to you for going out of your way to be considerate. Go RBG Nation!!
I got a predator 420 in an odyssey fl250. Fastest I've gone in it was 32mph with a GPS app..still gott put the bigger carb jet in it and button up a few things battery box etc.
I've got three different frames I'm going to power. One is a single seat so I figured I would put something mild on it, one is made for two kids so I figured something a little spicier, and finally a larger frame that's made for two adults. I was thinking about putting the 440cc snowmobile engine I have on it but I might build one of these instead. Advantage for the snowmobile engine is I already have a primary and secondary clutch for it.
I hope you talked to neighbor and acknowledge it was louder than you thought.That echo of the poppin and cracklin exhaust says how loud and mean it is.
Mr. Red Beard! DUDE!!! I have to thank you soooo much! The discount code got me $75 off a Duromax 440, which I was thinking of a Predator 420, but this engine has more power and was actually cheaper than the 420, even on sale at $299 I would have had to pay local tax! So $303 for the Duromax 440 shipped in less than a week to my door! Going to put that monster on a Silver Fox cart (very light but 4 wheel suspension!) TEAR IT UP!!!!!
Another great build ! With the different sized drivers you guy are,that adjustable seat is a blessing.Straight pipes are ok for start ups.Mufflers arrest Sparks so you don't set dry brush on fire.Speaking of...Extinguisher on that cart,and you're Garage?
We use the seat's that u have that was on the floor. Cause when ur turning sharp ur not sliding outta the seat. And yes we always wear a 5 point racing harness. Cause we drive the crap outta them. Took my wife's mom for a ride in the Sand rail. And she loved it except when i was doing Wheelie's.
I have a used small buggy frame and a 18 Durmax engine. I’m going to do an engine upgrade like you did with the same parts. What number tooth sprocket do you recommend? And the link for the 1” axel didn’t work.
that test cart looks like it'd be a breeze to add simple suspension to, jack-shaft at swingarm pivot point, couple bicycle coilovers rear, tall knuckles up front for the valve spring setup.
I Like it! Here in Detroit there was a Detroit Hood TV, a bunch of guys at Milan Dragway racing mini bikes and go carts for 18 mi. There was one guy (I think) with a motorcycle engine on a go cart and he hit speeds of 100+ mph ! That's what I'd like to do although I'm in no position to DO it, I'd love to!
So I’m looking for a go cart I will sometimes use in smooth farm fields but mainly on the road, some of the roads are cracked or uneven or have bumps, is suspension necessary? Speed is probably around 35
I’m excited for this bigger shop, do you think it will make it so we could buy some of these go carts from you ? Honestly speaking it makes it nice to see something built and know that the corners were not cut and the work was done right . Thanks for the videos and keep up the hard work!!
You guys ever thought about a central pivot front axle? wouldn't need shocks just a restraining strap to stop it going to far. that would be perfect for keeping all four on the floor.
I just bought a Duromax 18 HP 440cc for a go-Kart rebuild. ( First go-kart ever ) it has pretty large tires in the rear. My question is, how do I improve the takeoff speed it's very slow and take off ?
How do you like that Bauer bandsaw? I got a weird project going on myself. A mule like you did but with sportbike motor. It’s been a challenge designing things to fit
I've built a lot of Honda and predator engines but never one of these, what's the potential power gain that this engine has over the predator 420? Being a machinist I've gotten respectable power from the 420.
I know the bore and stroke of both engines but it's hard to calculate real world power gains, and I've followed RBG for years now and know that they're no strangers to the 420 😁 I wish I was on the RBG team... Y'all need a machinist? 🤣
@@RedBeardsGarage Awesome, so more potential for less coin 😁 I know which one I'm going for next. Thank you for the reply, I've been watching your channel for years, pretty much when you first started and I've always enjoyed your videos. I've told countless people to give your channel a look, some have built karts and engines, a few took their knowledge further and have built/are building engines for project cars, one is building LS engines with me. You have no idea how many people you have inspired, keep up the good work.
Red Beard's Garage, would you know where I can get a 15HP diesel stationary motor from America that will deliver to Australia for a cheap boat project I'm working on, I need 2 of them while using 2x 10.5" mud motor propellers. Sorry I know that boats & shit is not really your thing but motors are, thanks. Mark
I'm planning to do a 30HP kart (FL250/FL350 inspired) and I'm researching engines. Would a Stage 2 gopowersports kit Predator 420 with a Mikuni Carb get me to 30? How many RPMs are you getting with billet rod/flywheel and no governor? I can't find any info online about Stage 2 420 output. I might just end up going with the Duromax if not.
@@RedBeardsGarage Ok, just out of curiosity I did still watch your older Stage 2 420cc build, how much horsepower/RPMs were you getting out of it? Any info I can get will be a big help.
Hi, how are you? What size round tubing is that go kart made out of? I have a older one that I am trying to extend but do not know the steel type. However, it looks like the one in your video.
Hey ! i would like to do a mini bike project, with a predator 420cc or a Duromax, but for the same price i can get an YX 140 dirt bike motor ! What do you think about that ? In France we don't use this type of motor, is that really powerfull ?
RBG I have a Coleman ct200u-ex mini bike that I only had for a couple of months, but recently the clutch has been giving me problems, its been smoking and when I want to take off I have to hold the throttle down just to get it to go, would you happen to have some advice? And also I am a fan of your videos I love how you fix up the bike and go kart engines
@Red Beard's Garage Instead of using a complicated keyswitch on Predator-like engines, you could use an relais, that closes with no voltage running across is, to kill the engine.
Yeah I'm a little worried about the karts being loud because my next door neighbor is a super nice guy buts not a fan of loud and my property runs behind his house. Oh well not like I'm going to be running it at 11pm or something crazy.

Get up and gone! Great power plant.
I didn't think it was possible but you got me even more excited about the 390 build for my Manco "Farm Kart".
Please,yamaha 40 hp Enduro_ouatboards engine
I know this is from over a year ago but I’d love to see a mini turbo on that
When I was a kid we used to put dirt bike engines in go karts. The craziest (most dangerous) one was a Honda Odyssey with a 490cc Maico engine.
You should build a small oval flat track for those no suspension builds
I have a no suspension kart and I agree lol
yes, easy as pulling a drag around a full day with an ATV or something.
I've built those engines and it has more than enough power for big buggies!! I can't imagine how that feels on that tiny kart?!? That is GNARLY!!! And yes, they are VERY loud lol

for the twin engine you could do an independent rear suspension like rather be welding did on his twin engine
Nice lathe in the corner there. Those are super handy. Once I knock out a couple other projects I'm going to get mine up and running.
Thanks for the Discount Code!!!! I just ordered a Duromax 440CC for my boys Honda Odyssey FL250’ This thing is gonna be awesome!
Make sure to upload a video of it. I'm trying to decide between a Predator 420 and a Duromax 440 for a very similar build.
I got a predator 420 in an odyssey fl250. Fastest I've gone in it was 32mph with a GPS app..still gott put the bigger carb jet in it and button up a few things battery box etc.
Must put smile on your face when you see your boy smiling ear to ear. Nice

Holy Swiss Rolls ! That thing slings the big red bearded guy🧔 around like easy peasey 🤓and that cam is a choppin 👍 nice
I wish I lived closer to Tennessee!! That would awesome to meet you guys, and hang out with everyone!
Sounds loud, but has a lot of power.
RBG you need a compact tractor with a grader blade to pave a measured straightaway to calculate speeds & torque.
I hope you talked to neighbor and acknowledge it was louder than you thought.That echo of the poppin and cracklin exhaust says how loud and mean it is.
Dam y'all from the vid that thing seems like it has killer bottom end. Killer vid yall great job 👍👊
Holy Cow.....I live right next to Elizabethton in Johnson City and will definitely be taking the kids to the meet up.

Man that kart turned out good got so much power for us bigger guys..... can’t wait to see it in person smash the like button people ....
That's my fav kind of kart, small, big engine and ground clearance
My gx390 Baja Minibike had the same noise issue with the neighbors. Straight piped big blocks rule!
that laugh @ 16:11 says it all, shear joy !

Make a burnout kart. That would be Kool
awesome thanks redbeard!
Looks like a blast
Bruh, the off throttle stroke echos through the woods tells you how LOUD it really is! And i thought my buddies Stage 1 420 was LOUD lol 😆
mine was throwing flames om the exhaust it hasnt run in a long time tho
Which torque converter

Elizabethton is a few miles from my house! Unfortunately I'll be on a trike run in nevada that weekend. I would very much love to come to a meet!
Is the duromax 440cc better than the predator 420cc
Where did you get those tires and rims? I have the same frame and would lime to get same set up. Thanks.
Did you find out
🧔 Red Beard drag that roll of chain links fence over those ruts grates em down like cheese, add weight if ya have too, your welcome 🤓
Red Beard have you thought about building a 4x4 version
I would but it would need a roll cage. We actually have the stuff to do it just need to get other projects done first.
That cart is great. Thats what i would build
Braxton's squeeks of glee say it all!! Lol keep up the good work guys!
I instinctively turn my head every time he starts to weld.
No camber, no castor, no faster than 25.
lol 👍😎🏁
neighbors have no fun unless calling on you for having fun.
Will that DuroMax 440 fit where a Honda GX200 was? I’m upgrading a Coleman KT196. Want to know what fits.
Love it! Loud and proud👍👍
So I’m looking for a go cart I will sometimes use in smooth farm fields but mainly on the road, some of the roads are cracked or uneven or have bumps, is suspension necessary? Speed is probably around 35

An cheaper then Harbor freight but you get quailty too. Man thats a hell of a deal.

That motor is stronger than buzzard breath!

RedBeardGarage: What wheels and tires are those?
What would you prefer in a bone stock configuration between this 18hp and a predator 420 for performance and reliability
Shout out to all our TN boys
Yessir
How do you like that Bauer bandsaw? I got a weird project going on myself. A mule like you did but with sportbike motor. It’s been a challenge designing things to fit
You should put suspension on it I know it's just your tester but I think suspension would be a good investment
After this ride it for sure needs it
That thing is badass!👍
Dude! Way crazy! Love it, ya better get some insurance!🤣🤣
Which spindles, front hubs and rear hubs did you use? Wheels and tires? I looked on each video to see if it was listed and I didn’t see it.
The neighbors are planning a huge party after yall move! Hahaha

I didnt know you were so close! I live like 30 minutes tops from elizabethton, outside of jonesborough
This isn't a real redbeard video until you jump the driveway in it!!!
Looks dangerous af. AMAZING.

Sick cart looks like that thing is going to fly. Great job bud really awesome
Where did you buy that speedometer? I'd like to put one on my go kart I'm building
Bike stockiest do lots of different ones.
I was gonna put one of these in my King Midget 3. The factory engine is a 12hp Kohler, with a top speed of 50 this is probably a bad idea
Awesome!!!
Side note: what model everlast welder is that? And how is it holding up?

Hi.what cvt did you use on the 30hp please?
Fun vid, fun build! Why not plumb the overflow back to the tank?
WHERED you get the torque converter plate
It is lined below the video.
what kind of break set up you have
This thing sounds like a blown ear drum to me lol. Keep up the great videos!
Didn't catch the size of the torque converter or the pricing or where you got it thank you

I'm surprised that you guys haven't mad a 4 wheel drive go kart for mudding. That would be sweet. Lol
I guess the discount code is no longer valid for Generator Factory Outlet which is a shame
I think it needs a turbo and e85? Maybe who knows
No shock ?
You can hear that 30 hp comin outta that lil engine😂
I prefer a quiet intake. That burp sound lol
Top speed run ?
it probably doesnt need a torque convertor. But it would be more fun with one so.
Yeah I'm a little worried about the karts being loud because my next door neighbor is a super nice guy buts not a fan of loud and my property runs behind his house. Oh well not like I'm going to be running it at 11pm or something crazy.
Whats better predator 420 or dueo max 420
So it’s been a year , what’s the update on the 440cc on its reliability compared to a predator 420cc
I know you're busy with the garage but I have a question about a project have a Carl Heald tryke I'm looking for a good motor to put on it
Hi RedBeard, I've got a 35hp vandguard twin, what size clutch setup do I need???
