459cc Max Performance Vs Predator 420cc 🔥Harbor Freight Engines

[@MegaDoc1985]

Bought the 459 last week for a go cart I’m re doing. I’m looking forward to the future mods for this motor! Thank you

[@RedBeardsGarage]

Right on!

[@caseymoore9737]

Throw a 34mm mikuni and header with a little stiffer valve springs and you will be happy. The carb alone even without a header makes a huge difference in power

[@andrewely9198]

How fast does it go?

[@clayhunna7357]

@@caseymoore9737 what size pilot and main jet is inside the\your 34mm mikuni ? I just got me a 459cc and want to go the cheaper PWK flatslide 34mm carb route, be awesome to know the jetting size as a reference point to aim for. Cheers

​@@RedBeardsGaragequick question i have same buggy. What rims and tires are you running

[@Parents_of_Twins]

From someone who hurt their back lifting something heavy while bending over, young and didn't think, get your self an engine lift or something like that to put those engines into those frames. I was working as a hod carrier and reached over and picked up two bags of cement at 94lbs per bag and my back has never been the same. I was 20 years old at the time and strong as hell, I weighed 154lbs and could pick up 4 five gallon buckets of mortar and carry them. I started working as a hod carrier for my dad at around 10 and nobody taught me how to properly lift nor stressed the importance of lifting properly. Still at the end of the day it was my decision to move those two bags at once instead of doing it one at a time. Either way I deal with daily back pain now so be smart and be careful with your back.

I purchased the 459cc for a golf cart I'm doing. Haven't mounted it yet, but I'm super excited based on the videos you have up. The one part I really need is the exhaust header! I'm not really going away from stock except to the air intake and exhaust (due to space requirements).

[@brockueda4866]

How did it work out? A friend wants to do the same I am interested to see/hear if it was a good addition.

Just discovered this channel, and man I love it!! Awesome content

[@RedBeardsGarage]

Welcome aboard!

[@TimZ007]

Note the Yellow spring on the rear driven pulley. if it inward facing it would be a red spring. They usually come with red springs but tend to have more clearance when run this way outward. Not an issue with the kit but I have always made my own jackshaft holder for the rear driven because i am cheap lol. Its a pain. and tensioning the belt vs the chain is a pain too the cheap way. always needed a chain tensioner which makes more noise and places to fail and they do.

[@cwgreen1938]

I liked your comparison video. I am really excited to see the videos on the performance parts videos. Thanks. Just so you know, I watch most of Cars and Cameras videos and I think you are far ahead on construction, fabrication, shop efficiency, and almost all respects of a little engine shop. That is one reason that I am a patreon of "Red Beard's Garage".

Found this video while searching for engine replacements for my sons go kart. What a great video. You do a really good job of demonstrating what you're talking about. Question: will the 420cc Predator fit in my sons Coleman KT196?

[@rickburns3918]

I just installed the 459 cc engine in a utility S X S . I need help wiring the ignition switch to the engine and do away with the rocker start switch. Thank You. I love your videos.

[@landonpope7522]

I just bought a 459 yesterday It's going in my ez go gxt-804. Glad i saw this video The original 2 cylinder in the cart was terrible. Best way to run a pulse pump?

[@whopper2king]

Intake spacer that has a pulse inlet on it

[@pancudowny]

As I've said in another video, where the 224 & 212 were compared: I'd say the torque curve was the deciding factor in the results.

[@caseymoore9737]

And the reinforced block is huge, pretty much puts it in the same class as the tilotson

[@grunt11bs66]

224 has a plastic cam gear

[@teflondon1620]

first time watching.. u guys are pretty cool. earned my sub bro

[@erikrohleen339]

Driver is on backwards…. Which people tend to do on the 40 converters. This is mentioned a few times below in the comments and is true. The driver is fine to be mounted “backwards” just shim the driven to line up.

[@bryduhbikeguy]

That just looked like fun rides regardless to the engine.The 459 seemed to really pour on the torque earlier though.

[@drakrazerclaw5146]

I'll be getting a 459 after I wear out the 390 I have, hopefully more will be available by then.

[@nicolec7290]

Those are great tires I put them on everything I have. Carlisle all trail. All kinds of grip. & never wear out

[@joeybobbie1]

Great Video, I think you definitely need to get Rid of the Governor. I have a Brand New 420cc Predator Engine that has sat in my Garage for 3 Years. I need to find a Go Csrt Frame for it. I would love to find a old Honda Oddesy Frame. I would also like to buil up the Engine. Thanks for the Video.

[@liamdtraxxas2011]

When you went up the road and it hit the governor. I would say, it was where the cvt didn't push the belt up quick enough so it was in its lower gear for pulling off thn hit the governor and that split second the belt did it's thing and "changed gear" moved from small on the engine to moving up to change gears and gets smaller on the other end for top speed. On a scooter it has rollers in the variator pully on the engine and you can change the weight of thm witch will change whn it starts moving the belt so you're able to keep it at an rpm where the power band is for full power💯💯💯👍👍👍👌👌

[@Dr.Cypher]

What torque converter do you recommend if I will eventually upgrade the 459 but don't want to buy 2 converters.

[@gavinvetor5450]

Do you have to have the CVT and if you don’t will it make it a lot slower

[@Tacosgalore24]

At the very least, if you're trying to cut down on wind noise while recording, for the go pro, they make a simple foam housing that does a pretty solid job of cutting down on wind noise. Or if you're handy with foam carving, you can make your own for cheap. It's not one of those items that go pro really advertises, but it's worth trying out

[@rangerdanger126]

Hi RBG, just wondering if your still doing any projects with the 459cc? I'm using mine on a long tail mud motor. Been working ok for me, have heard some are saying their mud motor setups with the same engine are bogging down. Is there any performance upgrades you recommend. Anything you would not do? I know for my purpose do not disconnect the Low Engine oil sensor. Thanks Rangers... Lead the Way!

[@jgavinray]

What go cart is featured in this video? I see Maxxam decals, but would like to know if your willing to share. Wonderful content!

[@KJRaycing]

Thank you so much for this!!!

[@RedBeardsGarage]

No problem 😊

[@Nothingmore71]

For a large pressure washer you think it would be worth the extra money for the 459? Or just stick with the 420 I’ll definitely be pushing the limits of a typical 13hp engine with the pump I’m going with.

[@frankcastle7777]

Thanks for the cool videos and GOD BLESS you too man.

[@dyllongeckles2122]

This video really surprised me. I used to have a little 1 seater with a bone stock 212 on it and the governor shut it off right around 40 and it had about the same acceleration as the stock 420 on that cart. It's crazy to see how big of a difference tire size, weight and gearing can really make with these small engines. I'd love to have that 459 on my old go kart lol

[@igokarts4510]

"it's crazy to see to see how big a difference...." ❤️❤️❤️ ❤️

[@CODOutdoors]

Awesome! I'd go with the 459 just for the tourque!

[@mkuhlman77]

459 because it's already in my shed waiting for better weather. Yeah boy!

[@jamest.5001]

You should build a Dyno! You can use a motorcycle disc brake, or a large car alternator, or two, with the output shorted through a heating element, in water. and the brushes powered by a variable power supply, to vary load, the brake disc is the most simple,. And then a load cell and laptop, robot cantina has one, you should build one, or a large water pump, with a valve to restrict flow. About anything that will put a steady load on the engine, that will not overheat.. then you can make videos testing parts on engines for gains! Seems like someone mentioned a diy open source kit or something, to build a Dyno, then you can truly compare these engines!!

[@bradleyward285]

[@RedBeardsGarage]

Nice!!

[@tonyestvik7969]

Nice work! 459 cc 👍Can I use my CVT- 30 plate for the 40- series?

[@anthonyt2955]

That CVT isn’t set up to operate optimally. I know it kinda doesn’t matter since ya set it up the same on both engines. The way you’ve (go power sports) has it set up, the driver pulleys sheath, and driven pulleys sheath, are operating in opposing action. Meaning the driver sheath is moving one direction and the driven sheath another, they should move together in same direction, it isn’t a tav 2 … this is wrong according to comet and physics. Love the videos though.

But after 100 miles non stop your 212 would blow up and my 420 would be running without a problem.

[@r0ckworthy]

How come this new sport is made around torque converters and centrifugal clutches instead of manual transmissions and standard (motorcycle) clutches? Seems like it'd be more fun with a clutch pedal and a 4 or 5 speed manual motorcycle-type transmission. Would be better for hill climbs, crawling at low speeds, and fuel economy.

[@igokarts4510]

In process of installing a 459 in a FL250. I would like to run an oil pressure gauge but need the low oil sensor deleted. Will this be possible?

[@robb1165]

Mine appears to have a pressure switch connected to an electronic circuit that cuts the ignition. The circuit has a short delay to let the engine start. With the pressure switch unplugged the engine runs. You can install a T and keep the protection. Mine has had some issues starting in very cold weather, where I had to unplug the pressure switch to get it started.
