20HP Big Valve Predator 212 Runs!
HTML-код
- Опубликовано: 5 июл 2024
- After installing the aftermarket cam, billet flywheel, billet rod, and porting and polishing the head on our Predator 212, it's time to oversize the valves. We install bronze valve guides and install our new trick valves. Whereas the stock valves are 27mm for the intake and 25mm for the exhaust, our aftermarket pieces are 28.5mm for intake and 25mm for exhaust. We're also using a 24mm flat slide carburetor to help the engine breathe at high RPM, as well as 26lb valve springs to prevent valve float and help this engine rev to 9,000 RPM.
Thanks for Watching!

"I'm just waiting for your parents to come out" I just think of the movie "Step Brothers" these two guys LOL Keep up the great work!
Same.
Ike even looks like Ricky Bobby
This engine sounds GOOD
CarsandCameras everything y’all got sounds good
👏
You guys should go to stateline nc kart track since your so close
Yes
You guys need to do a gas golf cart build
You guys make a great team. I'm glad you two found each other in life and became friends. So that all of us are able to watch all the great things you fellas are able to come up with for small engines. 😊😊😊
You know what I like about you guys? You just go for it! If you sit and read about installing valve guides and cutting valve seats, its enough to scare an amateur wrench spinner off. Watching you guys do it, it brings it back to planet “do-able”. 👊
Them:
Chucks valve guide reamer in hand drill.
Professional engine machinists:
“Loud collective gasp”
And no fluid for lube/wash away filings!!!!!! Super cringe.
Nimbus Nimbus gay as fuck
I want to know what the throat diameter was😉
uh...no. we did not gasp
It'll be fine.
You guys are getting faster and faster at the engine mods. WAY back in the day, that whole process might have taken a week of sweat.
No small job, but damn that was all just according to plan and blueprint. Lookin' forward to seein' this monster on the road.
small engine, but still takes skill. You can't just go hacking the ports apart. Gotta be exact.
These guys have the experience now, but a few years ago, this rebuild would have been many more videos in the making.
It’ll be fine lol
Looks pretty awesome! Love your videos, Ike and John. This build is pretty big. Keep going, always ready for your next video!
You 2 are lucky because, you can feed off one another with questions and answers and of course the how to as your doing. Keep the videos coming. Thank you for posting.
I love the auto subtitles. It says music and applause when it listens to the motor or grinding.
@ 4:34, Actually it's the other way around... The more width you have contacting the seat, the better the valve can transfer heat, which will keep it cooler... However, the wider the contact area, the less flow/efficiency you will have... The 3 angle is all about making the port more efficient around the valve and seat...
Pretty much anything you do to an engine, or anything else, will have a "compromise"... ( like choosing gear ratios, for example... smaller "drive" gear & larger "driven" will give you more acceleration, but will be sacrificing top speed)
I believe that is one of the main reasons that we all have so much fun building our own stuff...
Just friendly "constructive criticism" from my own experience... You guys have done a lot of awesome stuff, and are also very entertaining to watch!! I've been enjoying your vids for years now... Keep up the GREAT work, and thanks again for sharing!
All smiles here fellas. That thing sounds great! Very responsive. Stoked for you guys!
Love the Grin after you fired her up with the new springs installed! Great video as always guys!
love your videos, been waiting all morning.
GEEGAN SQUAD SAME!
I'm ready to see an amphibious Go-Kart or Predator Powered River Boat build.
JeepCollector91 they've already made a short series on an amphibious gokart a couple years ago
+Aaron Johnson
I know. It was pretty much a failure. I am waiting on version two.
I offered them a 1974 Boston Whaler 13' boat if they wanted to use that as the base to build off...
We have a small dinghy donor we're planning on using! Thanks anyway!
watch some "Muskoka Sea Flea" videos you'll get it real quick.
fast build ruclips.net/video/gqTcuUMCwh0/видео.html
2.5hp fast ruclips.net/video/Cek2t4LtbeA/видео.html
go inboard 7-8hp it's gonna fly like a water-kart with the right prop on it.
+CarsandCameras
Great. I look forward to seeing that dinghy build.
If you ever have a need for the unsinkable Boston Whaler you are welcome to it. I'm sure I'll have it around for a few more years. I traded a sailboat mast and sails for it a few years ago so I don't have any money in it. I have the NC title for it so you wouldn't have any issues getting it titled & registered.
I live less than 4 miles west of the Winterville, NC Harbor Freight.
Been waiting all week for this video! Thank you.
Love watching you guys it’s the perfect mix of good information and science from John and the fun risks from Ike keep up the work you to
*She is Going to ROCK!!!*
It's a runner. That thing is gonna scoot. Great build fellas keep em coming
When your clearancing a crankshaft for the cam, it won't unbalance the crankshaft, I use Jr. Dragster engines which have clearance on the crankshaft, doesn't unbalance the crank. Last year, I replaced the crankshaft in my Jr. Dragster engine and it didn't unbalance it, we took off 1/2 inch on one side of the crankshaft just to clear the camshaft. We also had to clear some parts of the counterbalance on the crankshaft as well. I have worked with these kinds of engines for many years.
Really enjoyed watching you guys. This is the only mechanic show I watch that two guys get dirty and or stay clean. Mugshots just tell you what's going on and you never see the person dirty. Boo boo. I also like the way you guys think consumers need more information you show it less information you don't show it I like that. Not a boring story like most car shows.
This old guy has not missed a video since I started watching a couple years a go. First time comment...You guys rock...
Love the video super awesome you guys are great love everything you guys do keep up the good work love the builds
Cool video guys, thanks for taking the time to make it, and post it. very informative!
After watching hundreds of precision machining videos watching you ream with a hand drill physically hurt my brain. Glad it worked !
I pictured John's dad in the living room watching T.V., rolling his eyes every time you guys revved it up.
...Or his Mom saying 'that little bastard, he never lets US do a couple laps around the yard'... :p
Just a thought, for balancing, you could weigh the crankshaft, make your adjustments, weigh it again and make a note of the difference. Then when grinding the other side, you just take that difference off again and you'll know youve take the same weight off both sides
cncgeneral Yeah, most people don’t have a scale that can handle a crank and accurately measure it.
Jimmy Alfonso Yeah, did you actually watch the video? It's tiny, any small precision scale will be fine
I was thinking the same exact thing
Thnx.I'll do that when I do this.
Hearing it run at the end of the video....but not SEEING the kart run down the driveway is a bigger cliffhanger than The Empire Strikes Back LOL )
Like your guys videos, some pretty sweet and smooth mechanical and engineering work and congrats to you both and hopefully theres no limit to your success. Good job and thats how to live life, love that effort of the team work man.
I definitely think that exhaust needs a support. Vibration will definitely put strain on the head, and possibly crack the flange bolt holes (i think). Nice job guys
Wouldn't the oil contain lots of metal glitter? I would definitely change the oil before the first ride. Damn, that engine sounds good.
Everytime they do cam and flywheel work they always leave the oil in and barley ever change it never makes sense to me I always always drain the oil before any internal work
You guys are super talented and I really enjoy the videos. Keep em coming
Another great build guys!! Thanks for the entertainment!! Merry Christmas You Two!!!
Save a trip to the dyno.. aem and tons more places sell wide band O2 sensors. Buy a bunch of O2 bungs and plugs. Throw the Bosch wideband O2 in the exhaust and read the AFR real time.. adjust jetting as needed and then remove O2 sensor, install plug and on to the next one
Jeremy the thought had come to mind when they were messing around with a turbocharger on a Trike.Trev NZ
Now thats a mean 212
Nice work fellas. I like how snappy the throttle is. Happy motoring
Congratulations guys really cool to see you guys made it on TV
Plz make longer vids btw i still love u guys
Man, I want to come over with my race drone and chase you guys on your track. That would be some great footage.
That is the best go kart motor I’ve ever heard. Sounded amazing for what it is.
always love the vids, especially this series.
WAITED ALL MORNING
2:45 Cringe complation 2018
@13:21 Thank you for providing the clarity on when to upgrade a CARB and what size should be used.
I don't know if y'all are thinkin what I'm thinkin or not but im thinkin four performance built 212cc predators on the awd kart!!! You've GOTTA!!!
I never thought I say this about a 1 cylinder but that thing sounds great. Really hoping you guys can achieve 88mph as planned.
Then you'll see some serious sh*t!
A touch of Nitrous would finish the build nicely. I’m sure the motor would be fine.
Yeah... Like Redbeard did..!?
It Used those little Sparklet's, that Chef's use for Whipping or Rather Air-reating Cream..! It worked okay for 8min's, but I'd o' thort a Doub or Tripple Shot wouldda' hit the spot Perfick..!
Not those shitty little bottles, a proper wet set up with a decent bottle.
these blocks crack in half at 13+ hp. Revving it with no load is fine but once they sit their big asses down and hammer it, it's gonna give.
Should never take metal bolts out of aluminum when hot.
Im as happy as you are! Love the vids!
Absolutely love it guys looking forward to your next video :-)
That engine sounds great. I bet it will do over 88 mph
How many minutes of swearing was there during the cut away for putting the valve spring retainers in with the higher tension springs? :)
Hahahahah. Many minutes Bryan.
Really looking forward to see the new clutch setup installed and this thing running.
Please upload the fails haha!
@@CarsandCameras thanks for not swearing on camera so I'm able to watch with my sons .
@@Smokeslingerowner you big pussy. Let them hear the words
I'm about to start ordering like a madman from gopowersports now... Thank you guys!!!
GPS sucks, their parts are overpriced and they have terrible customer service. Go to NR racing, they have much more high quality parts, they are priced accurately, and they have great customer service
3 Angle Valve Job? Come on y'all, the kids are watching! Just jaggin', rock on, boys. That engine passes my ear test- NICE.
Yinz have a friend in Pennsylvania. (412) in the House.
#Praise the Lord , son!
It said “Itl be fine!” In the freezer!😂
Ike I would of taped the journal during grinding, I hope it's not pitted. I enjoy CC videos. Have safe ride.
chuck hoyland yep, me too. All three bearing areas.
I couldn't watch. Small bits of hot metal hitting the journal at high speed and welding themselves to it.
Haven’t been here ina while from the looks of it this channel should be called karts and cameras now
Love the vids guys , keep em rolling.
It's like a gear jammer drag car engine of go-kart engines 😂😂😂
*"I'm going to try and balance it out"*
You guys are having way too much fun!!!
This is incredible thanks for sharing!
*HAVE YOU SEEN THE CLEAR VALVE COVERS AT GPS ?????*
they look incredible
did you change the oil after break in?
keith w yes after the first 10 hours of run time
@@conner5611 Conner & for anybody else reading: use a dedicated 4 cycle MX type 4 Stroke oil or Lucas Brand still has the Cam & lifter zinc etc additives that now aren't in most modern automotive 4 stroke take home 4 L pack's, especially needed at break in or if you've Changed the Cam & Lifter buckets - same applies to the industrial Flatheads like the B & S & Techumseh etc...keep the revs up around 1500-2,000rpm for about 20 minutes to 1/2 an hour,then use the old oil for the French etc Freudian slip lol I used to race with Castrol biolube semi-synthetic 2 Stroke & dear by the HP increase but I know Lucas oils has what's wanted.Trev NZ
You guys have really changed gocarts for the better. Thanks
John looks like a mad man at the end fire up of the engine funny as hell
Can you guys bring back all the old builds and do a go kart lineup ???
I met your mom in an airport restaurant, she told me to subscribe :) I'm glad I did! Great stuff! /bradtshortridge
Brad Shortridge how much
Lol...sprung...
You're a very good mechanic Ike. Careful in your movements. To work on engines components is not for all.👌👍
Great videos guys! There's a couple things I'd like to point out: What is said at 4:31 and 5:52 contradict each other. The truth is that you need sufficient width of the contact surface between the valve and the valve seat to allow heat to transfer from the valve to the cylinder head (which cools the valve). Too little and you'll burn an exhaust valve. Also, at 4:17, you're correct in saying that it could bump up the compression just the tiniest bit without that dimple in the valve, but it also adds weight to the valve. I think the additional valve weight would negate any gains from the compression increase.
Again, great videos guys. I just wanted to comment because I'm sure you have a lot of fans (including me) that rely on your information. Cheers!
7:46 did anyone else notice the it'll be fine sticker in the freezer.
5:21 - that's what she said! 😂
VA Outdoors Sportsman Lmfao!
Yep, perfect scenario..!
You're definitely on the right track with the definition of 3angle valve job....the purpose of 3angle valve job is to control the width of the seat ...like Isaac said you want it to be thin .020.is the ideal width ....and also back cut the valves which a lot of people don't do and don't know to ...but it does increase intake and exhaust flow...
Definitely the meanest sounding predator I have ever heard!
Get the literaly FLIPING crank Ballanced AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
The valve uses its contact with the head to dump heat. How does less contact with the head increase cooling?
Do R/C!
Not sure where he got that idea from too.
That's the only time the valve can cool is when closed ,and more contact means more heat extraction. I've had issues in vws,they want about a .120 wide contact area.
Get them much under .090 and watch em have much less reduced life.
Each surface needs to be the same width. By creating two more surfaces youre creating more surface area.
hes actually flat wrong... take it from a mechanic... the full seat is supposed to seat
KanJyro well not the entire seat necessicarily. In a 3 angle job only one angle will seat but definitely not intentionally making the sealing area smaller than it can be.
Probably he mix with valve edges that cant be sharp because it burns of or something. p.s. sorry for English its not my language:D
Another great sounding engine guys can't wait to see how fast it goes.
Sounds absolutely awesome!!!!
you should try to do that to a 670 that would be awesome :) !!!!!!!!!!!!!!!!
I’m gonna say weight to power ratio this is gonna be your best build to date
yeah i agree..i was thinking the dragster was fast for power to weight ratio but this little 212 sounds really horsey and by the looks of it very responsive to the throttle cracks..ought to be quick fer sure
You haven't seen the Ducati cart then lol
Enduro_Xr150l they literally just shoved that motor on the frame, I’m talking ground up build
Enduro_Xr150l I also said nothing about most power to weight ratio
A tip when using the reamer, I HIGHLY recommend using thread cutting oil when reaming the hole. It will give u a smoother finish and smooth equate to more power even in the valve guides.
Man, I thought the video was really informative. And cool. The one thing I can say as I've watched hundreds of mini bike builds, mods etc...u guys had a good shop and all the tools.
This is cool and all, but that engine setup costs over $1000! One Thousand Dollars! Now I know it is cool to have a built 212, but that is not a lot of hp for the money in any way, shape, or form. It must be nice to have sponsors haha.
Yeah, MMmmmmm Sponsor's...
Iron Ridge Outdoors people build 212s because of the size most of the time mabe like on minibikes they dont have unlimited space and for this gokart it was built for a 212 I assume.
For the same effort/money you could have thrown on a cr80 engine, a yamaha cart engine and a variety of snowmobile engines. All of which will fit where a 212 would with minor fab that these guys have done many times in the past. Don't get me wrong a built 212 is cool, but I'd never even consider it at $1k. So many better options. Different strokes for different folks I guess.
Buy a used 125cc dirtbike two stroke engine with 35hp
Iron Ridge Outdoors it’s most likely because the place that supplies them parts doesn’t supply them with dirtbike motor parts like cr or crf or every other brand
That thing sounds NASTY
Great video, looking good guys!
I've watched lots of videos on hot-roding 212s and everyone grinds off the flashing on each side of the throw, you are the only ones I've seen grinding the cam shaft. It doesn't hurt the crank to grind off and smooth out that part, and, you can grind a little off the counterweight to restore the crank balance. Grinding 25 or 30% of the cam is asking for a catastrophic failure
Spring for the 3 year warranty? Haha
i Like IKE
You 4 Real.!? Who couldn't Like Ike & John.!?? An Taylor an the Dad, and Ike's Bro, Boss, an o course Dem Pesky "Chiiiiken's.!???"
Esskit Esskit
Wha bout John?!?!?!?
Thort I'd mentned John..!?
"I like Ike," was Eisenhower's presidential
slogan, when he ran the second time.
Since his Veep was RMNixon, "I like
Dick" would have been in poor taste.
steve
Ike is awesome......cant say the same for john
I love the back to the future movie so props
17:11 Jon looks genuinely happy here 😂
You guys need to buy a lathe. If your going to keep building this motors
I agree, they need a mill and a lathe to do more accurate work.
Larry - a well set up mill will do most of the work a lathe will do.Trev NZ
Whatever happened to the turbo kart you guys built?
Steven Barnette You mean the drift trike? I miss that build but it was kinda a disaster
They
Steven Barnette garage
the pure happiness on Johns face when engine starts up is just too funny 17:11
IKE is a master at solving unsolvable problems
Gets 100$ engine, spends like 7x more on parts. Logic!
3X the output, and it's still small and lightweight
Minibike time!!!
Weight + power = money in anything bro. Guns, bows, cars you name it performance equals money.
Do this vs 3x predators on a gokart, geared differently obviously (Itll be full of torque, not hp)
I meant the 3x Predator 212s would be a torque monster.
20 HP is an overestimate for a 212cc GX engine. 12-13 HP would be appropriate. Even a 210cc Cg motorcycle engine has 12Kw(15.5 HP).
its not. a stage 2 makes 16hp and this is a stage 4... might even be making more than 20.
Wow it sounds really good guys great job!
Tip: If you don't have a freezer handy, get an air duster can at Wally World, turn it upside down and spray it on the item you want to shrink. I use it all the time removing and installing bearing races in axle housings. Easy peasy.
You can also use a paintball CO2 bottle. which is what I honestly would use. Those air duster cans leave a residue from the bitterant they put into them.
CO2 doesn't have the same kick as dust off.
Liquid CO2 does. Turn a paintball CO2 tank upside down and vent it. It sure as hell has more kick than dust off does.
co2 is heavier than the atmospheric air for one, and for two, co2 is actually painful to inhale since your body doesn't want it. You've clearly never messed with CO2 in any meaningful capacity.
Boys, boys! Play nice! Cheese Whiz!
SMASH THAT LIKE BUTTON 👍
Go Karts or Gone Fishin
In the face, LIKE A BOSS!!!!!
You think 26lb is hard try doing 80lbs even with the tool that’s like a lever I have to stand on the table and push down on the lever to push the springs down with my foot
Sounds natty. Can't wait to see how it runs. 🚀🚀🚀
Sounds like a BEAST!!!!!!
