I could watch this video over and over and never get tired of it
very nice video! I love the little window you added so you can see the flywheel! I always hated how those beautiful flywheels just got covered up.
+MacroMachines that's exactly what I was thinking when putting the stock side cover on. That's why I did it. Lol.
+Red Beard's Garage i saw a comment response where you said you would make a " Mikuni carburetor tuning" video.. has that not happened yet? or was I late to that party haha..Thanx
Youre doing a great job! Taking you time and oiling everything up instead of bashing that thing together like many others do.
Thumbs up!
We had a few mess ups on this video. The valve springs you should use in this build would be 65lbs from go power sports. Also do not oil the bearings before placing them into the rod as this can make you spin a bearing. Thanks for watching!
Oh, you caught that. Sorry, I had already posted before reading the posts.
Oh yeah I am posting as I watch. Do not oil the bearings if you are using plastigage. It will give a false reading.
In most areas you can use cam lube or high temp bearing grease for initial breakin lube.
This is an excellent how to video. Forget the kids, it makes me want to build something me....hahaha. Can't wait to see this monster in action! How about little red kart 2.0 ? Too much motor? This motor with a Duster 94C/90D set up would be scary fast. I think 3.5:1 ~ .78 overdrive. With a 5:1 final drive you could still get 60mph top end and have stump pulling hole shots too.
Red Beard's Garage what torque converter can you use on this or honda gx390 ?
I'm totally blown away , Top shelf build all the way through and a nice attention to detail start to finish................Okie.
+OKIE CHOPPER thank you brother
Red is the Man. Best Videos around closeup and in HD. I learned everything from these Videos. Awesome
Thank you sir
Dude I have never seen such a well put together video, The manufacture couldnt have done better A-Plus my friend!!
Thank you for watching sir
What a great how to video man! Very detailed excellent job!!
That's one beautiful engine! I love the splatter effect on that cover!
Thanks man
Dang that engine looks nice. Awesome video! Thanks!!!! Love the splatter paint, too.
Thanks man
Awesome video! Great editing, wonderful attention to detail, and the paint on the cover was a sick touch! TWO THUMBS UP!
i didnt know there was so much development you could put into this engine wow
Yo BIG UPS and many blessings to you and your . This was one inspiring video. Really cool can't wait to heard it to run❤💛💚
This thing is sweet! Can't wait until it's on something!
Excellent job dude. Very professional.
That blower housing looks awesome with the paint splatters.
Great job and description of the job being performed. Thank you.
All you haters knock it off this guy saves us all a lot of money and time . Thanks Redbeard your a star!
Awesome build, been watching your channel for a little bit and just realized I’m not far from you over in the Sevierville area. Keep up the good work.
YOur Tutorials are absolutely EPIC!
valve lash checking has always been a favorite for me
Best how to video I've seen yet! Very good. Thank you sir!!
Rather watch this then Powerblock Episodes. Very detailed and very well put together video.
Thank you brother
That has got to be the BEST video I have seen on this subject!!!! VERY WELL DONE!!!!!!!!!!!!!
Thanks man more to come
I seen u on the ARC live stream glad to see u getting serious with your performance builds keep it up
Amazing vid,kids these days dont know how good they have it.............I'm not that old but we had to figure this stuff out on our own when I was doing it.
Very few would share what they knew to gain horsepower...
I have watched this video so many times and I can never get sick of it
Well thanks man
me to
nice... great lookin 420... now can't wait to see it on the kart
Dude that engine is soo clean it looks like it belongs in a really clean car 👍😎
great video, I have a small tip when you put the valve keepers in the valve spring retainer, if you put a small dab of grease inside the keeper it helps stick them to the valve holding them in place until you get the other one in and gives you time to make sure they are in the right spot before you back out the spring compressor. I hope it helps keep up the great work!
this is the video iv'e seen on your channel and omg the content is such high quality and bloody love your videos.
Your step by step vids are bar none the best on the tube thanks man
WOW what a quality video. i watched the whole thing
Thank you man. The engine is somewhere over 20hp. More mods to come
thank you man for answering me i'll be here for the next vid that's for sure
Cool video, very thorough explanations of everything.
Dude that cover with the sight glass is freaking sick!!
+ttali211 thanks man
These motors are extremely easy to take apart and put back together.
This video was so good to learn the OHV engine.
Great detailed video. Was a little unsure about using valve lapping paste that close to a crank seal. However changing a crank seal looks a hell of a lot easier than changing the starter motor.
If you took the rotating assembly to a machine shop that does balancing and have the crank flywheel rod and piston balanced you could get more rpm out of them without disintegrating and a trick to keep valves from floating is go to a hardware store find a spring that would be just a bit more than the tappet in closed position use a washer against the block to prevent spring wear on the block this trick will get you more rpm before you reach valve train limit.
As always, bad ass vid and very detailed RBG, thanx again man.
Thanks for supporting us man
Beautifully presented video! ave has an interesting video on removing bearings such as the balance shaft bearing with greasy rags and a hammer, the procedure has saved me a couple times. Keep up the great content.
I tried that method on this engine with no luck so I used my welder
ooooo look at all the shiny race parts !!!!
Love the shroud
That's freaking awesome
Awesome build
that cut up side cover is brilliant. Im gonna copy you.
Finally figured out the Patreon site! Took forever( probably cause I'm old). Left a comment today on yesterday's live stream video, but I did get to see most of it last nite. Packing to move so didn't get to see it all.
Well man thanks for watching and supporting us
Night*
Great Video! keep it UP!
Well done young man. Cheers 🍻 from England
Thank you sir
I liked this vid, I ordered that spinning base and the colored bolt cups.
That is a great video i watch it a thousand times!!!!
Thanks for always watching man
Turned out nice.
Best looking 420 I've seen
Thanks man
Weird this would pop up in my feed today, I was just eyeballing this engine in my harbor freight catalog this morning. Can't believe how inexpensive these beasts are. Definitely want one now
That cutaway clip at 14:10 got me. Sub'd and everything. Amazing detail and info red beard. You are a TH-cam hero for me and my little brother. We've been binge watching for a few hours.
Thanks for sticking around man. Lots coming so stay tuned
Dude thanks for making this video
Your the best builder I’ve seen on youtube
Well I appreciate that man
Man, this almost makes me drool. Looks so good.
I probably won’t have one of these for a while but man this is cool
cool work brother
Awesome, build...!!!😎
VERY well done video!
You make this look easy peasy
Great Video with great information
Very informative well made video!
Great job
Fricking sick splatter paint man
+Zachary Fromm thanks man
Awesome thanks for the great video!
Once again great video!!
Badass build
Amazing my friends
Thx for video you saved me some money
I liked this build. What I would like to see is someone take the time to do a progressive build on a 420 cc predator. First Dyno a bone stock engine. Record power at all rpms and length of time to reach full speed etc. Then as you make performance changes re-dyno the engine at every change recording the same categories as the first Dyno. That way we could see which improvements would give us more bang for the buck. I know it would be a tedious job and time consuming. I am sure many of your viewer's would be interested in knowing the same thing as me. I realize you are probably strapped for time, though.
Really great video I learned a lot.
I will probably never get to do this kind of tear down and build, but I still watched the whole video. Great job. Your video should be required watching before posting a "how to" video. Very clear, concise and interesting. Now where did my ex-girlfriend hide that Predator motor I had in the workshop.
Cool ,smooth stage by stage explanation easy to understand for us mechanics like u in another country.
In our country most of our best mechanic never had experience to study at a decent school..
In short.. Cannot understand english.
Crap Mr. Beard! The least you could have done is let us listen to it run lol. Nice build there RB. Very informative and professional. I like working with ANY motor but the small ones always peaks my interest. I ran a 44mm MickyRooney (Mikuni) years ago on my 1948 H-D Panhead..nice carb! I am now looking at a circa 1964 Briggs 5 h.p. from a Simplicity Snowblower that was my Grandad's back in '64 lol. It started to get tired about 20 yrs ago so my bro and I kind of refreshed it. New valves,a set of rings,light hone and a breakerless ignition. It runs well,just needs something to be bolted up to! That chasis on the '64 Simplicity is made out of pure steel and ways a friggin ton! Keep up the good work man!!
Great work from Australia
Nice video! Amazing content!!
Thanks man
Red Beard's Garage I love your channel I watch like all of your videos :) I have always wanted to get a go kart there amazing your are so cool :)
Looks so good! I wish I could afford to build an engine like that. Can't wait to hear it rip! FYI those auto lite plugs only last for a few hours of run time. I have gone through about 5 of them on my predator.
Ngk is what you want
Fried Chicken where can you find them?
If you are young cut some extra yards in the neighborhood. Save and get you one
I would think you have to adjust your mixture. Any spark plug other than those chinese cheapos should not foul that quickly, or at all really.
nice new clean motor. i'm jealous.
looking good my man. love to see you hook up with a motorbike dyno shop and do some in depth videos on carb tuning/timing etc. as I'm sure it could greatly help a lot of your subscribers. Just a thought!
+Jarrad Powell I will see if I can find one close to me
+Red Beard's Garage oh I forget sometimes you are living in a relatively small town! maybe if you can't find a dyno some tuning with a home made O2 sensor can be just as productive and gives an awesome understanding of what's happening with your fuel/air adjustments!
Awesome job as always. So informative, cant wait for the street kart redemption
That motor looks nice
Thanks man
Im 1st time in your channel...big thumbs up 4u sir..i'll subcribe
IT'S A BEAUT!!!
GREAT VIDEO
Thanks
Never in a million years would I have imagined the time, effort, and money that could be invested in one of these little engines..... Not my flavor, but dang impressive.
Nice video and guide
It's very nice.
WE GET IT YOUR RED!!!!!!!! 👿
I like this channel, good man is red
Men youre good thank you for share
Best build vid to date! Jody at ARC would be proud.
+Doug Smith thanks man.
Nice 🙌🏾👏🏾👏🏾👏🏾👏🏾👏🏾🏁
Awesome 10
I like the flywheel cover I always thought it was a waste to hide such a cool looking part good idea with the window view may try something like that on my kart
Omg dis is a beauty
Good job, and modified it
It would be nice to see it fire up. But very professional and informative video. I did like And subscribe can't wait to see more
Thanks man we got a video coming out soon on this engine on a kart
