You got the best videos when it comes to rebuilding motors
Thank you sir. We have a lot coming out so stay tuned!
Love the tutorials. These are the kind of videos that started me down my bike build process, and soon to come after, a mini cross kart build. Keep em coming!
only channel that can make a lawnmower motor sound like a drag motor
Damn dude, this is such a professionally done tutorial video. I felt like I was back in shop class with Mr. Brendall watching Top Fuel, lol. Can't wait to see yall send it on the trails.
Absolute beast of an engine. Love it. 🤘🏻
Love these engine build videos from you RB! 👍👍🤘🏻🤘🏻
We have a lot more coming
So much for being able to reuse head gaskets like old times.
I really got the Spike TV power block vibes from this video and I love it!
That think looks like a beast from the factory! I like to check piston to bore and ring gap before I put them back together. Being air cooled and as hard as it’s going to get run, a little extra clearance goes a long way, even if oil consumption goes up a tiny bit.
Dammit Red I always enjoy watching you taking shit apart and putting better back together this is what I want to do grow up to be just like you big red baddddddd!!!! Kudos sir always a fan CR from Lakeland Florida thanks
I hope they are working on Billet flywheel too! I guess that and a cam is next for this engine.
Just love your how to videos. Thanks for sharing the knowledge.
Thank you for supporting and watching!
Great job Red Beard.I never seen this engine before.You made it way faster.
Yuns should build an airbox around that filter!
We are in a later episode.
@@RedBeardsGarage yes I was hoping to see it because that NC mud is fine! I know how yuns like to put it to its limits! Just don't want that to be his limit....
That thing sounds incredible!!! Love the work
It would be great if you could add some sort of bench power testing to your engine builds, even if only to compare output 'power' of various engine projects. A 'poor mans' dyno could be as simple as running a hydraulic pump against pressure restriction @ GPM flow rate (I'd need to think about the setup a little more). Point is you don't need to give actual HP readings, but before/after results would be helpful. "Racing' parts suppliers are quick to toss around HP gain numbers by using their parts, but no one really knows..
That's awesome I thought the 420 460 was the biggest single you could get I'm thinking this would be awesome in a mega Moto bike for a fat guy like me . Awesome videos
I have one on a Mega Moto and it's a stump puller. You won't be disappointed.
good engine build God Bless
I know it makes them cheaper but it would be nice to see roller bearings on the PTO side of the crank like old cast iron engines did, I've seen guys have these kinds of engines on kids class pulling tractors and ruin them because of all the load on a non roller bearing
It would be a lot better. I will see if I can track down some to replace on the 420cc engines and install them in a future video. Great Idea!
@@RedBeardsGarage I thought I saw at some point that the 212 and 420 had aftermarket covers that used roller bearings. I'd love to try one out compared to my kohler singles and twins but the fact that some of mine are belt drive with a lot of axial load I think I would fry the crank and case
Hey red beard this older and better looking red beard. I just wanted to say I enjoy your videos , but i wanted to help a brother out. I've got factory training for a couple major motorcycle companies, and one thing both would castrate you for is using a magnet to remove or install valve spring keepers. They say and I saw it during training the keeper can become magnetized and collect metal shaving resulting in bad stuff happening. Your better off using some fine tip needle nose pliers. Have a good one !
Mo' powa babeh!
Lekker Rooibaard, good video!!
Excellent video friend.
Red Beard garage is the #1
Utube channel for learning how to mod motors and installing hpp up parts and bolt on hop up parts... I have learned sooooooo much from these viddz.. plus I've got parts and tools from the links in viddz..#RBGBESTHOW2HOPUPCHANNEL
KEEP THE GREAT VIDDZZ COMING RBG!!!!!
I love it
Looking forward to seeing this big thumper rip.
Nice engine super beautiful.
Sounds meaner than my wife when I shrunk her favorite sweater in the dryer.
How many Horse powers, this engine make....
Port match the intake? After installing keepers I like to give a little tap tap on top with hammer to make sure they seat.
That's going to be one peppy buggy.
That rod looks like the 459cc rods with slanted rod .. wonder if that would work head looks close to same too
To hell with youtubes ads!!!
Any word on cams or billet flywheels coming for these at some point? With such large ports and a big bore, a cam could really make a massive impact.
Performance 670 got one to do some testing but are waiting to make sure they are sticking around before putting time into it.
@@RedBeardsGarage how you think plastic oil pump gear gonna do that’s something I’d definitely I’d be leaning on someone to make but think of the possibility oil cooler piston cooling jets then timing could be higher and with an oil cooler could add more oil then keep motor cooler more power
Sounds like that big dog is ready to eat.
Are you gonna use a billet flywheel?
Unfortunately there isn't one on the market for this engine yet.
@@RedBeardsGarage Oh ok because I know that you really stress that when you do upgrades on motors
Who sells a billet rod now that Vegas carts no longer does?
Do you think a bullet flywheel and piston will ever be produced for this 620 zongshen engine 🤔 its the only thing holding me back from buying one ,curious what rpm your running this at whats your working powerband with this setup, you have come a long way 👏 congratulations, btw,
Its around 21-23hp stock and after this build should be 30-35hp
That piston is huge compared to the engine size holy crap.
Sounds like you might want a bigger main jet
It actually needs a smaller one. She is black after a few minutes of riding.
Are these engines better then the 670. Building my off road cart
So when are you going to make the next video I'm patiently waiting
The turn table.
Hey, where did you get the taper shaft adapters for the PTO side clutch?
Billet Rod link is Dead. What is the 625 Stock Valve Sizes? What is the Stock CAM Specs? Is there a cheaper Alt Oil Filter?
I'm feeling a little cringe about exhausting directly into your intake. Was there no other way to route the exhaust?
RBG - What engine do you think performs better for the go-kart the 625cc or the 677cc harbor frieght?
what is the crankshaft size is it a 3/4 or 1 inch or is it bigger this motor in stock form could be a good replacement a TrailMaster Hurricane 200X it has 21 HP with 42 Max Torque and tune the Idle Speed to 900 RPM'S and upgrade the jackshaft to run and handle a 780 Driver / Driven Combo system and do a frame stretch or lengthening and reinforcement if needed with stage 1 performance upgrade Intake and exhaust only.
Where am I able to get one of these engines, I have a 99 CC, GX160, Predator Tillotson 212, Tillotson 225 Champion 420, Predator 460 stroked, and a 492 Stroker. I would really love to have a 625cc mini bike along with all of my others
Even HF isn't shitty enough for a plastic cam gear.
I have to say I was disappointed in that when I opened it up.
i wonder if i can govern my my as much as i want until she blows?
I just got two Chinese go karts. They had it listed as 45 mph top speed but I only get 30. What can I do to make it go faster with out spending to much money. I was thinking of changing the CDI but a lot of reviews say that don’t make a difference.
Really curious about the black box the throttle cable comes out of. Is this drive-by-wire from the pedal to that box?
What's the stock HP and the modified HP? Do you have a dry weight? I checked out the website but those figures weren't listed.
Its around 21-23hp stock and after this build should be 30-35hp. I don't know on the weight.
@@RedBeardsGarage Thx!
Is it wrong to say id love to put this on my mini bike?
Hey Bro can you Use any Boot for the Carb I have a Honda Flathead G400 and the Koso Carb don't fit on the Adapter and I still haven't found a Compatible Mini Bike yet for that Giant engine
Is the camshaft compatible with a "gx390" style cam?
No it is a lot larger. I think there may be some aftermarket parts coming out soon for it.
Any reason to get this motor over building up a 670 vtwin? They’re about the same price but I’d have to believe the twin gives way more torque out of the box.
Lol any go power sport coupon codes👀👀👀😝😝
Another solid video. Question: Harbor Freight is coming out with a 223 engine soon. Will you be getting one and doing a comparison or something with it. Curious what is different.
Yes sir already have talked with them and we should be getting one soon
Plastic camshaft ??
Yeah it was disappointing to see
Wait .. aren't there supposed to be bearings on the rod and rod cap? Did I miss something or am I just way far behind in technology?
Most of these 'honda clone' style engines do not have rod bearings from the factory
What happened with that SEMA Kart build, will you complete that?
I'd like to know what the temp difference is between stock and upgraded.
Is there a billet flywheel that can replace the stock plastic one?
There isn't at the moment. Hopefully performance 670 will start making parts for these engines.
I wouldn't mind seeing a custom long tube intake on an engine... Especially if it was built for low end torque
I use the agk manifold on small blocks. It's got a great runner length
What hp are these engines before upgrades and are they reliable?
Did you not put on new valve guide seals?
Whats that valve compression tool u got a link for that
My go kart is a KD-200GKM-2 what performance part do you recommend to get a faster speed???
No billet flywheel?
What would be best size push rods for 212cc hemi predator?
When they gonna bring the rod back for this? They quit making it. Not worth buying if you can't replace the rod
Now, I can honestly say that I don't know enough about this kind of thing... But *theoretically* a connecting rod for an engine with the same stroke length, wrist pin and crank diameters could work if the rod's widths are the same. Again, *STRICTLY* theoretical.
I know the carb. Has rubber neck. But it seems as thou it doing a lot of vibrating on video.
We're did you get the spacers for primary clutch
So your saying the Stock 23hp@3600rpm with these Basic upgrades is 30% more hp? 23hp +30% = 29.9hp@3600rpm! 625cc turning 3600rpm making 23hp Dials in at 85% VE. 85% + 30% = 115% VE = 30hp@3600rpm. These Engines should be able to be turned up to 5000-5500rpm with the basic upgrades. 625cc at 85% VE at 5500rpm = 34hp, and at 115% at 5500rpm = 47hp. Max hp and continuous use hp is different. 47hp@75% = 35.25hp. 625cc at 115% VE used at 4100rpm = 35hp, use at 4500rpm = 38hp, used at 5000rpm = 42hp. What Size is the Stock 625 CAM? With the different Engine, Ceramic, Moly, Heat Dispersant Coatings, you could turn it to a higher rpm. Try one of them Cheap Laser Heat Guns next time you build one and see what your CHT & EGT are. Used at 3600rpm these Industrial Engines are rated for 1000hrs. These 625 have an Oil Filter so I take it has an Oil Pump also. Wouldn't a Billet Rod with the finger to Splash Oil like most have be better? Using the Hybrid Crank Ball Bearings, Steel Races with Ceramic Balls which needs less Oil, last 3x, Run Cooler, but do Cost more.
Just don't know if any Rubber boot would work that can handle Gas
Do they offer a steel cam gear?
What's the hp/tq on these babies stock?
18.8hp and 31ft/lbs of torque.
This is a proquip engine 20 hp engine sir right?
Yes, it is the same engine. Zongshen GB620
Where did you get that engine spinner?
Where did u get that spinning table top.
It's linked in our amazon affiliate. amazon.com/shop/redbeardsgarage
What size is the output shaft on this 625?
What was the cost ?
Does anyone know of any aftermarket cams for the 625cc?
What is the safe rpm range?
how do you order the manifold?
What is the base engine?
34mm carberateur and we put on our 125 2ts 41,5mm so they can work correct😂
На русском бы посмотреть. Где брать такие запчасти?
It’s so quiet
Dyno run
Yikes!!!!! Plastic cam gear!!!! Oh no!!!
I thought the same thing too.
Hate that plastic cam gear
I am very interested in this engine for a paramotor quad. I know I can get the engine but cannot find a billet con rod. Vegas carts stopped production. Are there other con rods available? Also is not having ball bearings on the crankshaft a big deal? Also are there camshafts available?
