I remember when you built this engine. Was awesome to see how it held up. If possible please do more episodes like this.
These definitely need an hour meter to know for sure what the life is like over time.
No shit sherlock🙄
They're so cheap that a 12dollar hour meter increases the price 15 percent
Love your channel, great content! Those are pretty decent little engines. I have a Predator 3500 inverter generator with the stock 212cc with 10,000 hours on it. I've cleaned the carbon build up on the heads several times. Also had too swap the head/valves recently cuz the valve seats were shot. Wish I had your expertise. I'm more of a hack than anything, but at least I've kept it running to keep the lights on. Keep up the good work, you guys are great.
10k hours is crazy! I have a Renegade 3500 generator with the exact same engine, but it's a 212cc Loncin motor, which is who makes the Predators for HF
Just got my predator 212 msd style from you today and I'm absolutely in love with it and haven't even put it on yet. Thanks redbeard!!!!!
Super interesting. Gold standard in small engine content.
Love the videos bud!
We’re a mud mower group called off-road wheel horse team but your content has inspired me to build my own mini bike!! Few vids of it on my channel but no where near close to being done. Keep it up bro, love it!!
Looks like excessive heat stress fracturing there on the block. Doesn't look like wear and tear like something be hitting it. Just Looks like that is where a lot of heat pressure was building up. Might want to tig or jb weld that spot and give just that side a bit of heat shield cerakoting.
The teardowns are something to keep pursuing, very cool🤘
That's awesome, that thing has held up great! Love your transparency with all the flaws and damage! Good luck to all who hope to win this engine!
The dust comes from the filter adapters to run the big filters. They need a gasket or oring or something. Had this same issue. The adapters just attach with set screws and aren't a tight fit as soon as the filter does its job air start going to the crack cause there is no restriction.
Very interesting and educational video. Especially for someone just getting into 4 stroke engines. Can’t wait to see the rebuild video. Heading to Facebook to start following you there as well. Thank you Sir. Great video.
Thank you!
RB you should be checking your crank rod journal for roundness with a Micrometer! 👍👍🎉🎉🎉🎉🎉🤘🏻🤘🏻
I took the steering off my kart to shave weght. I just lean to one side like a skateboard. Faster than hayell!
Ditch the brakes also, because who needs them anyways right?
I deleted my girlfriend my car goes much faster😂
@@carbide1968 power/weight!
Nice tear down just my opinion, the block down by the oil drain. I would use liquid metal to seal those cracks before they get worse .
Cool video of the teardown! Never seen a bearing break apart like that pretty crazy!
Man would I love that engine! I’ve got a go kart that I picked up cheap 2 years ago that’s missing an engine plate and engine and this would be perfect. Too bad I’m not on Facebook and instagram. No worries though. I still live the idea about breaking these down from time to time and checking the internals out.
good point i gotta check my valve spring gap thingga majiggas thanks man
Allsome work from cruzermans inventions 😁🎉👍🌟
Great video man.
Nice job. It would be neat to see a side by side comparison of a stock engine with similar hours/mileage.
Awesome timing, I was just thinking about getting a 212 to replace the stock 196 in my Coleman Minibike. I waited until I was ready to get the parts for a band brake assembly on the centrifugal clutch, and can do the whole thing at once. Because I live in a bunch of hills and ride downhill a lot, I wanted the peace of mind that I had two brakes. Whatever 212 I get will be to get me back up the hill, as the 196 just makes noise when I start from a complete stop on the hill and doesn't move.
Get a 224cc
@@mauricedavis2905 I was looking into a 8HP motor, but wasn't sure if all the bolts would line up the same for the jack shaft bracket or not. It looks like the 212 is a direct swap with minimum fabrication required.
@@mcdoctorglock the 224 is just a factory stroker HD version of the 212
@@mauricedavis2905 Thanks! I just looked it up a little while ago and found that the nearby Harbor Freight has them in stock- cheaper than the 301 and the 212 Ghost. I'm going to stop over there in the next couple of days and check one out. Maybe I can fab up the clutch band brake bracket and jack chain bracket together and swap out the whole thing at one time. Should I do a direct chain or keep the stock jack chain setup? How do you tension the chain without the jack chain tensioner?
@@mcdoctorglock if the 224 will work without interfering with the jackshaft it would be simpler to keep it(most likely). If not its usually pretty simple to delete if the engine and wheel sprockets are on the same side already. Unbolt it(or cut out if not possible), check sprockets are in line with each-other, run a longer chain and buy or build a tensioner. Im sure theres videos here on how to do that last part
I'd like to see the tip of the oil-dipper.See the dent from the block.To me,the damage on the crank bearing looks like the oil had all baked off while it set,and turning it over ripped the plating off the bearing.You guys started it and there's the damage to the block as the crank tip hit it.
Beard, I would get a new block Hoss. It was flexing.
I like your splatter paint job.
Love the setup
Too cool I have a similar set up based off the build on this engine it's on its second season and still going strong ,I would have never tried if I hadn't found rbg so thanks to rbg family👍
Tachometers are awsome for keeping track of hours. What do you think this hemi was making on the dyno?
Love the videos. Keep it up. Where is a good place to find a mini bike to mess around with?
Aww man I don't have those social media accounts.
I wonder how piston holding up.yea that engine looks really good nice quality parts 👍👍go power sports damn I spoke to soon I guess it still did pretty good from ur clips I can tell it's been beat!
Whatever happened to the Kohler command? I lost track after the first video lol
Super video
Where do you get the Allen head covers and is a ghost a hemi head I’m getting ready to build one for a junior dragster
Can you link to the blue side cover bolts you use? Thanks for the great videos.
Was the oil dipper on the rod hitting the block?
When you have that many crank shims how do you know the rod journal is even centered to the cylinder?
How do you know it would be centered to begin with? Its a cheap china motor lol. now you have me interested in measuring this
With that many,I would've divided them per side too.
Because they go in front of the crank and not behind so if the crank is fentered but has play adding shims between the side cover and crank will stop play
That predator 212 looks like it makes 25 horsepower and 30 foot pounds of torque and and I would like to put that predator 212 on my four-wheeler and I can't afford a predator 212 I subscribe and ring the bell and like this video
Hello great video. Love watching your videos. Do you have any golf cart frame's for sale. Looking for 3.
I could use that 🔥
That’s awesome! You mention hour meters , I’m sure you know they are relatively inexpensive and easy to install. I grabbed one off Amazon when we got our new engine (stock) and have been using it to log my oil changes and other major maintenance. Whoever gets the kart after us will have service records 😁 You should start adding those too
No shit Sherlock
Something else inexpensive staying in your lane keeping that trap shut nobody gives a fuck what you got to say.......
@@motorman1873 wow quite cheerful of you there 🤦♂️
I own and operate a Vapor Honing (and small engine) company here in Jackson Mississippi. I’d be happy to vapor hone your block and head (and even flywheel) for you if you’d like (free of charge). Andrew @ Mississippi Vapor Blasting and Fondren Small Engine Repair.
I knew tillys we’re tough. But 500 hours. How many hours should one of these go with proper oil changes ?
I was thin king the same thing......way too many hours.
I wanna put that on my mud boat
When will this motor be given away RED?
Can you take Tig wild the block it looks like the rods is ready to go Through the block
There has been one thing that bugs me when you talk about rocker arms “ratio” means the amount it opens the valve verses how much the cam moves all rocker arms are “ratio” rockers but in the aftermarket you get “roller” rockers where all the pivot points have roller bearings so the upgrade is “roller” rockers
yup i agree
👍
Red what is different in predator 420 hemi to not hemi just the head 🤔
cant i tell that my piston is at top dead center just by lookin in the spark plug port to set the lash on my ducar 212
I'm not an expert, but I believe it's supposed to be TDC of the compression stroke and not TDC of the "exhaust" stroke. He probably was looking at the flywheel(where the rusty part signals the spark generator to fire) and the piston position. If that helps?
hey fast ? i have a stock 200cc gokart i bought from redfox power sports (junk!!) anyways my belt on the torque converter keeps burning up!! i want to upgrade to a high end converter and what ever else needed to stop this problem also would like it to have a more power! what do i do and what should i order from go power sports?
How do you know when you should replace all of these things?
Are you modding that 999cc yet?
500 hours seems a bit steep even if the engine was assembled perfectly and the oil was changed every 3 rides. Dudes can burn an engine like that in a few races.
That's what I was thinking......see my post a few minutes ago.
We’re the pushrods stock length?
Hey Red Beard I have a question about the Predator Ghost. Is that engine stock comparable to a stage 2 212 Predator Hemi? You are the only one I can think to ask that would have first hand experience with both of these engines/builds :)
All you have to do is look at the performance parts they used on the Ghost. A PZ20 carb and 252 cam. I think they may have used low tension piston rings but big deal. These days I'm not sure why anyone would get a Predator 212. Any of them.
@@Deucealive75what would you recommended instead of a 212
Ummmmm did you post the other video yet I don’t really care about the giveaway I want the knowledge plz but I want to build a cross cart something with either independent suspension or the rear half with the suspension but idk i figure something out
Let me get the old coil and drain line, how much
Free just pay shipping. Email me at greg@rbgkarts.com
Come Red Beard.......500 hours? I have trusted your word for years but this is unlikely. I did some math........if you ran this engine for one hour per day, everyday for a year and a half that would be 534 hours.
It seems high for a modified engine as a whole. The block could possibly but at those rpms under duress I would think the rod bearings, rings and wrist pin would have been changed.
Unmodded these Predator/Loncin 212s can run for thousands of hours, but you have to be strict on changing the oil every 50-100hrs and keeping the valves in check every 250hrs.
Someone mentioned having a 10,000hr 212cc Predator in a generator!
How does the top end get oiled? You don’t keep a build sheet?
When its revved up the rod “scooper” slings it toward the top end past the pushrods
Tặng mình một con được không bạn yêu
i can upgrade but i cant afford for buy this machine type im fisher man and i want type of machine but i am poor😟😟
Rod was TO tight 😳
Nah my cousin got a predator 212 that thing knocks so loud he has the stage 2
That thing was running rich!! I'm not sure why an Iridium plug lasting 3 years is surprising?!?. They run over 100,000 miles. So the cerakote on block is purely cosmetic. I like some things there channels do with builds, but hate all the "snake oil salesmen" crap. You guys push useless "upgrades", that don't serve any purpose, wether performance or longevity. I know, Go power sports, appreciates the plug from their sponsor.... But seriously.
best is listening to Red not being able to pronounce oil or coil...he says it so it sounds like "oyow" for oil or "coyow" coil.. that evil "L"
