back in the 70s we had zero after-market. sweet thing was, my grandpa and dad had a small engine repair shop. i had a Briggs 15hp tiller engine on my mini-bike. bad thing was, the clutch was also the rap around rope start. something u wouldnt want to get ur leg caught in.. lol later my grandpa took a old dirk-bile clutch and put it on my mini-bike to get ride dangerous rope-clutch. that dirt-bike clutch made that mini-bike way more fun to ride. thanks for the video and ur time bro.
it's like the power wheels they just keep doing the same thing over and over . then they put a bigger motorcycle engine on it's like see how fast we can hit a tree ,, love seeing Red Beard build the engines the way he does ,, it's new ..not a copy of 15 other people .
Bought one of these engines to replace a clapped-out GX390 Honda engine on a Brister's Chuckwagon. Engine swap was quite easy with no mods needed, except wiring for the starter. Very solid sounding engine and incredible difference in performance. Very torquey. I think this will be a great platform for performance improvements.
Sweet. Also see if you can find the gapless compression rings. Love seeing the tear down on new engines. Also I enjoy see tear down of failed engines. See what went wrong.
We just put this engine on an Ariens 1336DLE PRO and it is AWESOME. Super interested in seeing a video on building this engine to be a torque monster but with longevity in mind. We need both for snowblowers and this engine is about the largest size wise, that we can fit on our snowblowers. If you make this video, it will also go viral. People around Buffalo need more for their blowers. Thanks in advance.
I'm having the same problem with my Harbor Freight Max Performance 459cc. I cannot find a Billet flywheel nor Billet connecting rod anywhere eventhough this engine has been on the market for just over a year now. Had I known this in advance, then I definitely would have went with the older Predator 420cc. I am in desperate need for some professional advice from absolutely ANYONE who has the same Max Performance 459cc who is also having some of the same problems thatcgv.,
@@michaelmcevoy7756 I just installed a 34mm Mikuni from go power sports massive improvement! Also the other two compatible parts I bought were 65lbs Valve springs and a .308 Cam from go power sports that’s what I’m installing next, so far 75mph with a 50T sprocket on a ct200u no governor 🤙
I am kinda excited! I haven't worked on any of 212's as they don't need it other than oil changes . Plus I have been busy playing around with my 2013 Dominator 800 . Looking forward to seeing what you guys come up with .
Great break down. Just scored one yesterday for 424.99 with the 15% off at harbor freight this weekend. I’m dropping mine into American Sportworks UTV replacing and old Honda GX390. Planning on doing a swap and review video on it !! Thanks for all you do covering the small motors.
Greg I thought I would pass a tip onto you for notching tubes I know that they are initially expensive but instead of using hole saws get yourself some end mills of the appropriate size they are quicker, more rigid, can be resharpend and lasting a lot longer, like the hole saws make sure you use cutting oil to extend the sharpness and assisting in keeping them cool You also use the same mills used with a MAG drill as well I hope that this will speed up and improve your notching Tony from Western Australia 🇦🇺
I'll be honest, the moment you build this engine the video will go viral. Please be sure to give us the spec on the pushrods that you build as well. I'm really, really invested in buying this engine for a mountain buggy build for this winter so it will be ready by summer. I've got my eyes on supercharging it due to my elevation that can exceed 7000 feet here in the Montana Rockies. I hope you can do this soon. And I hope gopowersports gets building billet parts for this right away. Also, that stock cam looks good as is and will most likely push more torque than a bigger lift lobe. It would be nice to see a longer duration cam for more torque but right now I think that stock cam would do everything I need it to.
Hey man I just came across your channel and I honestly regret not finding it sooner. I had purchased the 420cc a couple of weeks ago. It's been in the box, but I've done the research and decided to upgrade to the 459cc for the price difference. Thank you for the videos and please make more.
Thanks for sharing RB! I just put in an order for it on the HF website. I’ll be highly interested in any parts you get fabbed up for this thing ( minus the fly wheel) my plan is to use it as a surface drive motor on a boat.
@@bryduhbikeguy It needs basically a big stabilizing plate on the bottom aft at the same level as the middle of the prop. It smooths the water flow in a way that you'd get some speed out of it(makes it actually really plane out). Makes it kind of a torpedo like shape in the water looking
Had in issue with one when deleting the governor and tore the gasket so I rtv it and it made the cam seize up put ill loosen the bolts a 1/4 turn and it would free up so I believe you need to use the gasket for the correct spacing due to it riding between the block and that cover
I have one of the new WildCat 460cc. I did exactly the same as you, tore it completely down and went billet everything. Everything in my motor was comparable to the aftermarket world. BTW they now make reverse gearboxes for a 40 series torque converter. I've got one on the way. I can't believe that crankshaft taper is different, just use a 69mm "stroker" crankshaft, I've got several and i work in sweatwater every night. The WildCat block is super beefy and looks a lot like that one. The WildCat has a flat top Piston. It's crazy that the harbor freight engine is a 7 bolt.
The piston being so light makes me think you might be fine removing the governor, despite the rod cap being real thin. Not too much rotating mass so you might could get away with higher rpms
I just bought a dirty max because of the build yall did on it. Loving the full break down. I'm still trying to figure out the best carb and adapter for it. Red Beard, you're a stud. And your beard is magical. Rock on!
Flywheel removal- 2 ball pein hammers. Round ball on one hammer in center bolt hole on the crankshaft & hit it with the other hammer. No pry bar needed.
Can not wait to see how this new engine develops with time. I purchased one to repower. Is there any info out on how much the charging system puts out? Thanks again for all you do with these engines.
Love your videos man I remember getting one of your videos recommended to me, it was the predator 212 Schwin stingray mini chopper and thought it was really neat been into building and learning ever since you’re videos help a boat load when it comes to referencing for help
I'd guess the 2nd 'magnet' location on the flywheel is for a V-twin being built.Hopefully.Your measuring everything was Awesome.Best analysis I've seen on an engine tear down.Are the cam lobes timed correct enough,as the stroke is not the same,and also where the lobes are placed for the lifters in width?Thanks Greg.I'm always learning something.
I would suggest Dyechem on the crank to see which flywheels fit and which do not. It will give you a more accurate fit then paint and isn't any more expensive.
On that balance shaft, I worked in a foundry and rhat window cast into the balance shaft is usually just not cast into stuff as to save on material and it does help a Lil with balancing but just a cost cutting measure
Mr.Red beard , Thank you for what you do for Small Engine Community, ... You've help me in ways can't even imagine, lost brother an Best friend , in 2020 an 2021 an stop working on small engine, an your videos , keep my mind in right place! Have few questions, 1. What days do you drop videos ? 2. Can you drop more videos love your channel ! 3. can you build drag lawnmower ! Please 🙏 Thank you for your time.. God bless
Hey red beard. Can you verify the 670 twin exhaust flange is the same for the 459 single. We have the 459 on a little junior pulling tractor for my daughter and really need to finish up the exhaust for for. The 420 duromax we removed has a completely different exhaust flange orientation as well.
In your opinion do you think you could utilize the 3 bolt-holes coming off flywheel to add an extra belt pulley to power something power something separately other than what you put on the shaft side of the engine
i read somewhere that if u increase the volume between the engine and turbo it makes the turbo more effective on single cylinders because it delays the pulses. but im sure it it's a trial and error thing dependent on engine size.
At 18:30 it would have been nice to have a scale to compare the piston weight. That is a nice stock piston as far as can be seen in the video. I had 92mm pistons in an air-cooled VW with the stock 69mm stroke years ago; it is a very popular mod. ARC needs to build the rod and flywheel so you can spin it up 😏
I don't pretend to be an expert in this. But this new engine reminds me a bit of the old 350 vs 400 cu inch Chevy small blocks. The 400 had a longer stroke and did not compensate with a longer con rod. the rod had a much larger angle from from big end to to wrist pin. The outcome was that the 400 was rev limited compared to the 350. Stock 400s fell out of favor because of this. It will be interesting to see the performance potential of this engine compared to the old 420.
Awesome video. I need a backup engine for my 440 Predator heavily modded gold dredge motor and this 459 should work. I would need an open element air filter on to and a header. How about roller rockers like I have in my 440 hemi head? Would they work in this motor?
I would like too see a screw on oil filter system .. that way you can check it / cut it open / with out having to drain the engine .. also will the new rod keep the splash knife on it for the oil system ?? also if you did a oil filter system you could add a oil cooler to the system .. what is the inner and outer dia of the crank for the flywheel .. looks like a old B&S apposed twin vertical engine have a few of them flywheels kicking around plus a few others in my barn ,, 40 years of collecting and working on mowers .. great video Red Beard
So it appears the functions of the oil pump are to passively filter the oil through a screen which probably has a decently larger micron rating than the average spin-on, to provide some pressure to the assumed low oil ignition cutoff switch, main and balance shaft journals. Does that sound accurate? I was a little surprised not to see a ball bearing support for the PTO and MAG side of the crank shaft but I guess if it gets supplied with pressurized oil it really shouldn't matter as much in the long run.
Hey mate, Did you find a flywheel and piston rod to fit this yet? btw this look like a Loncin LC192FD 459cc engine which is the same number as the stock Predator piston rod. Coincidence?
This is kind of an exciting engine in that the possibility of 40hp, weight is important as I build ultralight aircraft and run 5k rpm so valve springs and rod strength is important.Looking forward to your modifications on this particular engine. Stripping all unnecessary weight might make this engine a really good option. Any idea of the weight savings with a billet flywheel?
Hey there RB! As always another great informative video! I picked up a 459cc to swap into my Yamaha G9 golf cart. My question is will a 780 primary clutch fit the 459cc as it does the 420cc Predator engine? Also any luck on updates information on what carb and exhaust upgrades exist for the 459cc if any yet? Thanks in advance
After getting mind installed I love the performance. My complaint right now... The motor is COLD blooded and it almost always needs choke to start. And the choke lever does not have an option to mount a remote cable like the GX390 and predator 420 does ... I will need to bust out the 3D printer and fab something up.
Back in the day I was looking for a over head cam motorcycle head to swap on to my flat head Briggs, maybe find a 4valve head, maybe convert to timing belt, along with port work, it should make alot more power, definitely a better rod and flywheel, I also was thinking about swapping to a motor cycle ignition, and rotor, cdi ignition, that would spin up fast, may not idle slow, so mays well cam it up!
Hey red beard whatever happened with this 459 engine and what’s recommended for it to reliably spin up to 6-7k rpm!? Would love to see more video and modifications this platform!
Great video, thanks very much. This is the same engine on A-IPower’s generator model SUA12000E. I got one from my neighbor last week who said it was locked up and wouldn’t run. Only had 56 hours on the meter and looked brand new. Oil level was very low and the crankshaft would not turn over by hand with the cover removed. I’m thinking the low oil sensor failed possibly and it threw the push rod(s) or broke the cam journal? Am hoping to get in there to see what failed and your video was a great help.
Great video! On the 212 when you upgrade the exhaust and air cleaner you have to change the main jet. I imagine that will be the same thing with this engine. Do you know if the air cleaner kits and jet are the same as the 420? will the parts interchange? Getting ready to put the 459 in a golf cart and I'll have a modified exhaust and air cleaner kit, probably going to need to re-jet it. So far I can't find parts listed for the 459, except a complete new carb.
Hey RB I’m building a mud boat with the 459 and I did the governor delete I was wondering the best carb to put on trying to get most power thanks for help hope you get some exhausts for them soon!
Thanks redbeard! Great video. I have already built my exhaust flange and purchased 1. 1/2 pipe and was planning on using my gps silencer. Do you think I should use 1 1/4 instead for back pressure? I know it’s test and play at this point, just curious! Love your testimony btw! I have family in sweet water
Welp I guess I'm getting one of these to replace my 196 on my kart. Glad I waited a year before going with a 420. Now will a juggernaut 40 series hold up to this is my question. I also need to figure out gearing because 25mph is just to slow for the trials.
Does that oil in the engine come from the factory? I've got a Predator 459 sitting in an unopened box that I'm not planning on using. So I was wondering if the engine came without any oil. And I wondered if the inside isn't oil coated if moisture in the air might corode the inside. But if it's already oil coated it should be fine to let it sit unused without adding oil.
Super informative and interesting. You're telling the people what they wanna know. You could waste a lot of money buying part for the previous 420 thinking they'll fit and SOL. As far as performance mods and such i think it will be awesome to see you discover and inform others of what parts ya need and what all you gotta do to achieve maximum performance whilst keeping a relative longevity. I like seeing what you can get from these engines its basic and simple keeps it fun, not to mention alot of motorcycle engines don't have a great aftermarket support not to the extent of predators I mean considering the 212 makes 6 hp and you can build em to 20 hp+ pretty easy thats crazy gain
Biting my nails over here waiting for more 459 mods. Just picked one up this week. Keep us updated please brother.
What did u end up doing to yours
back in the 70s we had zero after-market. sweet thing was, my grandpa and dad had a small engine repair shop. i had a Briggs 15hp tiller engine on my mini-bike. bad thing was, the clutch was also the rap around rope start. something u wouldnt want to get ur leg caught in.. lol later my grandpa took a old dirk-bile clutch and put it on my mini-bike to get ride dangerous rope-clutch. that dirt-bike clutch made that mini-bike way more fun to ride. thanks for the video and ur time bro.
It’s pretty cool that predator is making new engines!
Words come out of my mouth when I talk!
pretty sure that "predator" is not making any engines and they buy and rebrand ones from chinese brands (loncin, ducar etc)
Umm nope. They are built in California
Any updates on the Rod and possible flywheel replacement? Thanks man keep up the good work
“Always sucks pulling apart a new engine” I agree. Every time I do one I think…. This may never run again…
But it sounds like they always do since you keep doing it!
But when you start it when finished man what a prideful feeling
Thanks for doing all you do with these engines, I have been repairing small engines for a long time but I always learn something new.
I appreciate your stance on using engines like this instead of motorcycle engines.

I wish the aftermarket would catch up. All i want is a billet rod and a cam tbh.
Can't wait to see what can be done with them before buying one. Thanks for the tear down comparison
Very informative, can't wait for the aftermarket world to catch up, people like you are a driving force for it. Thank you
Putting stock 459cc in a golf cart. What carb do you recommend for this setup? Governor has been removed
I am REALLY impressed with this engine. The piston looks like an f1 or sportbike piston.
Thanks, Red! Great video! And really appreciate your enthusiasm and innovative ideas for more HP.
I’ll usually drill an oiling hole in the rod cap on those predator engines, and polish down all the casting marks and flaws. Rlly helps.
Greg I thought I would pass a tip onto you for notching tubes I know that they are initially expensive but instead of using hole saws get yourself some end mills of the appropriate size they are quicker, more rigid, can be resharpend and lasting a lot longer, like the hole saws make sure you use cutting oil to extend the sharpness and assisting in keeping them cool
You also use the same mills used with a MAG drill as well
I hope that this will speed up and improve your notching
Tony from Western Australia 🇦🇺
It definitely gets good lubrication. I mean it has an oil pump and a oil dipper from the rod for even more
The oil system in my opinion is the biggest merit of the redesign and something I think the .224 desperately needs.
I'll be honest, the moment you build this engine the video will go viral. Please be sure to give us the spec on the pushrods that you build as well. I'm really, really invested in buying this engine for a mountain buggy build for this winter so it will be ready by summer. I've got my eyes on supercharging it due to my elevation that can exceed 7000 feet here in the Montana Rockies. I hope you can do this soon. And I hope gopowersports gets building billet parts for this right away. Also, that stock cam looks good as is and will most likely push more torque than a bigger lift lobe. It would be nice to see a longer duration cam for more torque but right now I think that stock cam would do everything I need it to.
I'm still waiting on parts to come back but I'm ready as soon as they get here.
Who should I send a stock casted connecting rod to, in order to have a custom Billet rod made? Please let me know... I appreciate you and Thanks
Will you still be doing this build ?

Back in the day I was looking for a over head cam motorcycle head to swap on to my flat head Briggs, maybe find a 4valve head, maybe convert to timing belt, along with port work, it should make alot more power, definitely a better rod and flywheel, I also was thinking about swapping to a motor cycle ignition, and rotor, cdi ignition, that would spin up fast, may not idle slow, so mays well cam it up!
Hey red beard whatever happened with this 459 engine and what’s recommended for it to reliably spin up to 6-7k rpm!?
Would love to see more video and modifications this platform!
The rod is a bit shorter but the height of the wrist pin holes on the piston might play in the difference Maybe?
Great video, thanks very much.
This is the same engine on A-IPower’s generator model SUA12000E.
I got one from my neighbor last week who said it was locked up and wouldn’t run. Only had 56 hours on the meter and looked brand new.
Oil level was very low and the crankshaft would not turn over by hand with the cover removed. I’m thinking the low oil sensor failed possibly and it threw the push rod(s) or broke the cam journal?
Am hoping to get in there to see what failed and your video was a great help.
Hey have you built up any V-twin diesel engines? There’s a Winsun 20 hp V-Twin diesel that looks like a good engine to use.
You've come a long way big guy...
What would you do to it for a club car precedent and would it work
Great video! On the 212 when you upgrade the exhaust and air cleaner you have to change the main jet. I imagine that will be the same thing with this engine. Do you know if the air cleaner kits and jet are the same as the 420? will the parts interchange? Getting ready to put the 459 in a golf cart and I'll have a modified exhaust and air cleaner kit, probably going to need to re-jet it. So far I can't find parts listed for the 459, except a complete new carb.
Do you think it will have more power than 18 horse 440 and torque at 15 hp ?
Should have measured the piston to head clearance to see if it we can close the squish gap to raise compression with a longer rod
Any future plans or updates on the 459?
Hey RB I’m building a mud boat with the 459 and I did the governor delete I was wondering the best carb to put on trying to get most power thanks for help hope you get some exhausts for them soon!
Is there any parts yet for this motor
U could probably get some stuff but nothing to really build it
I have noticed HF has been stepping their marketing game up the past couple of years.
I'd give it a year or so before aftermarket becomes available.
He won't, he needs the views to generate more revenue from youtube. To buy more useless crap and pay for the big fancy useless shop building.
Think I just found my future engine for my Owasso Trike
6622 adjustable timing might fit, just need to take off the charging stator
Thanks redbeard! Great video. I have already built my exhaust flange and purchased 1. 1/2 pipe and was planning on using my gps silencer. Do you think I should use 1 1/4 instead for back pressure? I know it’s test and play at this point, just curious! Love your testimony btw! I have family in sweet water
Short skirt piston looks really good. How long it last is the million dollar question?
Any updated build on this?
Welp I guess I'm getting one of these to replace my 196 on my kart. Glad I waited a year before going with a 420. Now will a juggernaut 40 series hold up to this is my question. I also need to figure out gearing because 25mph is just to slow for the trials.
You know where to find a 40 series juggy? That would be sweet.
@@igokarts4510 I'm thinking of going with the 780 kit that normally is rec for 670 engines because I plan on upgrading my engine.
@@mkuhlman77 good choice
I’m sold. I’m gonna get me one for my buggy build.
For some reason go powersports has no interest in making any performance parts for this engine. I dont know why, its an awesome engine.
Does that oil in the engine come from the factory? I've got a Predator 459 sitting in an unopened box that I'm not planning on using. So I was wondering if the engine came without any oil. And I wondered if the inside isn't oil coated if moisture in the air might corode the inside. But if it's already oil coated it should be fine to let it sit unused without adding oil.
Super informative and interesting. You're telling the people what they wanna know. You could waste a lot of money buying part for the previous 420 thinking they'll fit and SOL. As far as performance mods and such i think it will be awesome to see you discover and inform others of what parts ya need and what all you gotta do to achieve maximum performance whilst keeping a relative longevity. I like seeing what you can get from these engines its basic and simple keeps it fun, not to mention alot of motorcycle engines don't have a great aftermarket support not to the extent of predators I mean considering the 212 makes 6 hp and you can build em to 20 hp+ pretty easy thats crazy gain
Have you came up on a lumalm fly wheel yet
I have not
