Thanks for all the hard work feeding your subscribers killer content every week.
@@RedBeardsGarage I kinda wonder what your thoughts would be on something like a supercharged 70cc engine build. I hope to try to push similar power on my Honda CT70 that I've got up on my channel
RB, from old guy, from days of Ruppman. The 70's. This is by far the best tutorial I have ever seen on small engine HP upgrade. If I only had this in the 70's with the parts, I would have been the coolest kid in my Detroit neighborhood. Damn good job son. This visual experience will inspire some burgering young gearhead that he "can do it". Possibly inspiring him enough to stay focused and out of trouble. Great Job. God Bless!
Thanks to this video I was that young buck. I recently turned 20 and just finished this build and my friend he did do amazing. I can't wait to continue on this path. It is so much fun to put time and effort into something I truly enjoy.
A little advice from 45+ years of building engines. Running bolts dry into aluminum, (or anything, really) like when you checked rod bearing clearance, is asking for trouble - from incorrect torque squeeze to galled threads. It's good practice to fully torque the rod bolt fasteners as few times as possible - meaning, only torque them to full torque on the mockup install to check clearance, and on final install - 20in/lbs is plenty for the installs to check dipper, rod, cam, block clearances, etc. Running them to max torque every time puts unnecessary wear on the threads and stretch cycles on the bolts. You normally don't want to run the ring gaps top/bottom - this puts them on the thrust sides of the block/piston. They seal better and wear less putting the gaps on the sides of the pistons just above or below the pin hole.
Always the “iN mY 1000 yEaRs oF fiXiNg eNgInEs” it’s not a fucking f1 car where you rebuild it after 1 race. It’s a backyard machine this seriously only applies to min maxing not this…
And there's always the "I can't get a point across without insults and profanity". There are basic assembly practices that apply across the board, whether it's F1 or a backyard Predator. A galled fastener is just a cheaper failure on the Predator.
@@willieshaw2522 100%!! Some people are simply too stupid to understand the theory of "if you're going to do it, why not just do it correctly". You're attempting to speak common sense to people who probably use an impact on their wheels and wonder wtf their brakes vibrate. Good advice, don't let one dipshit with zero sense stop you from contributing your 0.02, sir! 🍻🍻🍻
Back when I lived in Florida I had a cheap old minibike that my parents bought me for my birthday and it came with a REALLY hard starting 5 HP B&S engine and I ripped it off, my buddy had bought a brand new Sun Racing Engines 26 HP single cylinder engine for his go-kart and never used it, so I bought it from him REAL cheap. I put it on my minibike and that thing was ridiculously fast. I was only like 12 back then and I'm 38 now, but I'll never forget that thing. My mom decided she wanted to ride it back when it had the B&S engine on it and she came FLYING around the house on it and rode it into a row of hedges that we had on the side of our house and straight into a railroad tie that separated our hedges from the empty field next to our house and she got folded. Turns out the throttle got stuck wide open and she couldn't shut it off...lmao
When I was about the same age 12 a friend down the street had one of them basic lawnmower engine mini-bike frames. It had a Hodaka Ace 100 engine in it. I think it went about 60mph. His older brother had a Hodaka 125cc motorcycle they called them Combat Wombat. They were full-fledged 2 stroke race bikes. The kind you can't let idle or they would foul the plug. Always had to keep reving the engine. This was in the early 70s. Some engines had two spark plugs. When you fouled one, you pull the wire off and put it on the other plug. That's because it was so common to happen. LOL 😅
Awesome job buddy,I enjoy your all your videos.. I have the Predator 212 hemi. I've got it on a Ct200u-ex. Bought the bike used with engine locked from no oil. Bought the 212 about 2weeks ago and all I've done is mount it. Haven't even rode it yet. I've ordered some upgrades and so far all I've received is my torque converter. Thanks for all your time you give to making sure we the little people know what to do to make our bikes a little better than the rest!
I love this step by step build! So informative! This video is sure to get up there in views as im sure anyone building this engine will look to this video for instructions.
Hey brother I just want to say thank you for your videos, these have helped me purchase the right engine for me and it’s extremely helpful for the builds on the Max Performance I picked up. Awesome work Sir! Thank you again! I’ll continue to share your vids.
Hey red really enjoy your channel, i never use any cerakot on anything so i don't know much about it, anyhow seems like that would have messed up the valve seats. There's a good way to check and make sure there seating correctly, put your value springs on and then spray the bottom on the head around the valves with soapy water, then take a blow gun with a long tip and put it in the and blow through(90 100 psi) good value job you won't have any blow by. I hope this helps, thank for all the how to videos 👍👍
Man you got me on this, I snap my 212 cam shaft today on my wood chipper. I might have to go get this engine and rebuild my old one if it's not chew to bad. I was thinking diesel but I'm doing this first
I'm curious how long the coating will last on top of the piston and the inside of the head and valves. Be nice to see ya pull the head after a few hours of run time and see how it's held up.
Man this stuff is so great to watch I have the money to buy the stuff but just don't have the tools or the time to put them together, with life throwing blows left and right this year I don't even have the time to ride my stock minibike, my downtime I'm working with RBG playing in the background you guys rock!
What impresses me is 20hp from an air cooled pushrod engine Sure, lots of motorcycles makes 20hp from 150cc, but they usually use DOHC water cooled engines
Your mechanic skills are real professional. You just do everything right no matter how long it may take. I’ve seen some guys just not have the patience and rush the build. Awesome work man. New subscriber here.
This is quite the build. I don't know if I could of tackled something like that. I think, personally, I'd have gotten the Predator 670 V-Twin and called it a day. But that's just me. I'm lazy like that.
There are others doing builds. But none this extreme and in depth of what problems to look for and how to solve them. I waited for yours after seeing a couple of videos that just isn’t as good.
I just finished my engine build thanks tot his tutorial and i am so grateful. The detail was impeccable and well planned. I greatly appreciate how much time and effort you put into it. I definitely plan on building a vtwin now that i have the 224 running. Id love to show you my project thanks to you. The relief of it running as well as it did is all thanks to you. One question though, with your vaccum lines why not just run the one instead of 3? I get one is for pressure relief and one is for fuel. But why the 2nd pressure relief?
Dang, that’s a cool little engine. That cerakote is pretty awesome too. I’m probably rebuilding my oil cooled GSXR engine this year (if I get my shed built) and they’re a ridiculously hot engine. I’m going to look into cerakote for the pistons, valves, cases and cylinder block.
Wish you would put a loop in the exhaust system behind that cover. It would really give a deep tone to it. Would take some cutting on the old briggs racing exhaust but it would sound so good 🤣👍.
@@bradensmith888 look up a briggs and Stratton hoop racing exhaust they give low end torque and make predator engines sound way different. But modification is required to get them to fit because how the exhaust ports are different angle from briggs to clone engines
I did a non hemi predator build,arc flywheel - rod - mod2 265 cam Mikuni carb- pipe n swear I double Hp,n governor deleat,had to make wheelie bar because at 20 mph just gas it n your riding a wheelie 🔥💕
I’m late on watching this video and am not trying to put anyone down or start an argument but from what I’ve learned from building and working on many performance engines grinding the block for clearance would be the best option when you grind on a rod crank or cam that messes with the balance and could cause vibrations and possibly failures just something to think about.
Thanks for the video's. I think Im going to build a super engine for my son's Cycle Kart. Normaly the club runs 5 hp 212, but my boy is big, and I want him to be able to complete with the other Cycle Karts. Thanks again,
Curious to know what the compression ratio comes out to with that much material take off the head + flat top piston? 🤔 still on pump gas or is race gas needed at this point?
I can understand the build if a person were to do it in stages and can appreciate all the cool parts but in the end you have around 20hp for 2K in an engine that I would not consider reliable compared to other options for the same money.
Just curious about something, is there any issues with balance , after you having to clearance the crank,rod , and cam ?? I thought those would all be balanced from manufacturers? Just curious
I'm building a 224 and I'm using champion rockers. I want to get billet retainers to switch to automotive style with keepers but I'm not sure if I need to run lash caps on both sides? Or not at all? Any info would be greatly appreciated! You're channel is one of the best tools a small engine builder can have. Can't thank you enough man just for giving me the confidence to open up a predator and doing internal work. Thank you
very impressive build and i enjoyed the video. Did any of that grinding mess with the balancing of the engine or does it not really matter that much with an engine of this size?
Awesome video!!!. I don't know Predator motors. What was the hp to start with?. Looks like a really good build with really nice parts. The only thing I didn't like was the grinding for clearance part. No way to do it and keep balance in your home shop. How much did this build cost?.
Man you are such a expert..I think I missed when you put the piston and rod in witch way it goes..( I know but did u say ?) And when you showed the lash cap did you say what is and what is for ??? I am not judging you..my grandson 10 years old watch the video and asked me..your so good he says he can build one to just by your instructions.... thank you with all respect sir
Rod is oriented with the dipper on the cap at the bottom of the crankcase. With that orientation, the piston is installed with the arrow pointing down to the bottom of the cylinder. Hope that helps you. Now go build a screamer.
The lash caps go on the end of the valves. They are hardened and will take the pounding the rocker arms will give them. I was more concerned with all the "clearance work done" That is a lot of grinding and not for the faint of heart.
I knew witch way it installed ...was just trying to point out the way it went so RB could add it for the inexperienced builder RB is a damm good instructor just thought he missed that part. ....from now on I will keep my mouth shut
@@toddmeanie6003 I'm sorry if I came off the wrong way. I genuinely thought you didn't know and were asking. It's cool. As for what I said about building a screamer. I was referring to you and your grandson getting out into the garage and putting one together. Make some power dude. Small engines are a great way to learn hot rodding at an early age.
Curious if you gave feedback to the manufacturers of the cam, connecting rod on those clearance issues… most don’t have that cutaway hemi cover to see those interference issues and would have had some head scratching to find where it was hitting… thanks!
'We're going to rebuild a predator engine to make if faster... so first we're going to replace the cam, carburetor, piston, connecting rod, crank, block and jug with aftermarket parts. Then we're to use an aftermarket head and port it and replace the valves, valve springs and lifters. walla, we made our predator more powerful.'
First of all.. im really impressed with the build quality you do for all your project.. :-) How much would an engine like this cost after the upgrade..? Can it compete with the high performance CT70 style engines where a 20hp engine cost around $1000..
You wouldn't happen to know of a readily available belt drive transaxle that would work for a golf cart? I bought a duromax 440 to swap it but it's a 2 stroke ezgo so it uses the motor/generator to operate reverse. I've got a OG dingo and thought about robbing the open diff out of it with a reverse box but I'm torn. Excellent work as always man keep it up. Hopefully you guys make a trip out to Johnson City this season. Buffalo Mountain is awesome in a SxS.
hey, I'm in the process of building a 224 right now and have seen a few things about needing to mess with the timing key for the flywheel. just wondering if you just used the stock key or had to find one that worked?
@@byker283 all engines "huff and puff" as the piston/pistons move up and down so the crankcase is subject to constantly changing positive and negative pressure; particularly at high rpm. I had blow-by issues with a bored out VW flat four, ran a piece of tubing from valve cover to valve cover and cured it. This 224cc IS vented to the atmosphere, straight up and has a filter on it; I route mine to a "catch can" on my BT200X an early 224cc built at 72mm x 55mm.
@@frederickwoods5943 I understand that, mine is vented as well, but why put it back into the valve cover just to vent it out of the cover? Mine comes out of block to a vent on the frame with a 2 foot piece of hose. And why is their 2 vents coming out of the side cover. Once should be sufficient.
@@byker283 I agree. I've seen guys "vent" from the side cover right to the rocker cover. Are they trying to get extra oil into the upper valve train? The sump area of the block is already vented through the block and head into the upper valve train internally. Extra venting could just be done from the top of the rocker cover into the atmosphere. Or like you have done with an open vent right out of the block with a long hose.
Hey, RBG, how would this motor survive being used to push a small boat with a long tail mud motor kit attached? I've seen a couple of people {perhaps even yourself?) say that stock motors work best for this purpose, and that performance-built motors used like this don't live for very long . Apparently it is because of substantially higher sustained RPM's being involved. 🤔 Any thoughts? Thanks for the video. 👍

I’m late on watching this video and am not trying to put anyone down or start an argument but from what I’ve learned from building and working on many performance engines grinding the block for clearance would be the best option when you grind on a rod crank or cam that messes with the balance and could cause vibrations and possibly failures just something to think about.

Curious to know what the compression ratio comes out to with that much material take off the head + flat top piston? 🤔 still on pump gas or is race gas needed at this point?
depends on the cam. Static vs dynamic compression
Can you go over pricing for a build like this? I’d also like to see you drill and tap the relief venti holes and install tubing
I started adding up the build cost on this engine build and quickly surpassed the cost of a used cbr1000 running engine.
I can understand the build if a person were to do it in stages and can appreciate all the cool parts but in the end you have around 20hp for 2K in an engine that I would not consider reliable compared to other options for the same money.

Awesome video!!!. I don't know Predator motors. What was the hp to start with?. Looks like a really good build with really nice parts. The only thing I didn't like was the grinding for clearance part. No way to do it and keep balance in your home shop. How much did this build cost?.
Man you are such a expert..I think I missed when you put the piston and rod in witch way it goes..( I know but did u say ?) And when you showed the lash cap did you say what is and what is for ??? I am not judging you..my grandson 10 years old watch the video and asked me..your so good he says he can build one to just by your instructions.... thank you with all respect sir
Rod is oriented with the dipper on the cap at the bottom of the crankcase. With that orientation, the piston is installed with the arrow pointing down to the bottom of the cylinder.
Hope that helps you.
Now go build a screamer.
The lash caps go on the end of the valves. They are hardened and will take the pounding the rocker arms will give them. I was more concerned with all the "clearance work done" That is a lot of grinding and not for the faint of heart.
I knew witch way it installed ...was just trying to point out the way it went so RB could add it for the inexperienced builder RB is a damm good instructor just thought he missed that part. ....from now on I will keep my mouth shut
@@toddmeanie6003 I'm sorry if I came off the wrong way. I genuinely thought you didn't know and were asking. It's cool.
As for what I said about building a screamer. I was referring to you and your grandson getting out into the garage and putting one together.
Make some power dude.
Small engines are a great way to learn hot rodding at an early age.
Bad @$$, Red! Sounds so strong!
Curious if you gave feedback to the manufacturers of the cam, connecting rod on those clearance issues… most don’t have that cutaway hemi cover to see those interference issues and would have had some head scratching to find where it was hitting… thanks!
The video wasn't sped up he's really just that fast
Great build !!!
oooooo that sound. love it
try a backcut on the valves next time it helps flow as valves start to open
One word SICK!!!😎😎
'We're going to rebuild a predator engine to make if faster... so first we're going to replace the cam, carburetor, piston, connecting rod, crank, block and jug with aftermarket parts. Then we're to use an aftermarket head and port it and replace the valves, valve springs and lifters. walla, we made our predator more powerful.'
Road to horsepower-can’t wait! How soon?
First of all.. im really impressed with the build quality you do for all your project.. :-)
How much would an engine like this cost after the upgrade..? Can it compete with the high performance CT70 style engines where a 20hp engine cost around $1000..
around 2000 dollars
You wouldn't happen to know of a readily available belt drive transaxle that would work for a golf cart? I bought a duromax 440 to swap it but it's a 2 stroke ezgo so it uses the motor/generator to operate reverse. I've got a OG dingo and thought about robbing the open diff out of it with a reverse box but I'm torn.
Excellent work as always man keep it up. Hopefully you guys make a trip out to Johnson City this season. Buffalo Mountain is awesome in a SxS.
How many hours do you expect that engine to last? If you're pushing it?
One question can you use the 212 predator billet parts for this engine ?
hey, I'm in the process of building a 224 right now and have seen a few things about needing to mess with the timing key for the flywheel. just wondering if you just used the stock key or had to find one that worked?
I personally used the stoke key
Yip true 20 hp is a lot of power for sure 😊👌 cool
RED BEARD IS TOP NOTCH💯 PERCENT
Do you have a video where you cover the crank case venting? That’s what I was most looking forward to in this build.
I will make one sir.
Yes I would like to see that and why is there two. And why are you not venting to atmosphere? Thanks!
@@byker283 all engines "huff and puff" as the piston/pistons move up and down so the crankcase is subject to constantly changing positive and negative pressure; particularly at high rpm. I had blow-by issues with a bored out VW flat four, ran a piece of tubing from valve cover to valve cover and cured it. This 224cc IS vented to the atmosphere, straight up and has a filter on it; I route mine to a "catch can" on my BT200X an early 224cc built at 72mm x 55mm.
@@frederickwoods5943 I understand that, mine is vented as well, but why put it back into the valve cover just to vent it out of the cover? Mine comes out of block to a vent on the frame with a 2 foot piece of hose. And why is their 2 vents coming out of the side cover. Once should be sufficient.
@@byker283 I agree. I've seen guys "vent" from the side cover right to the rocker cover. Are they trying to get extra oil into the upper valve train? The sump area of the block is already vented through the block and head into the upper valve train internally. Extra venting could just be done from the top of the rocker cover into the atmosphere. Or like you have done with an open vent right out of the block with a long hose.
I'm amazed your engine, what is the size of your piston? and how much is that engine setup?
Would you go any higher on cam lift and duration with the 1.2 rockers? Trying to figure out if I should get ratio rockers or not for 275 cam
do you think this could work on my BT200X
Hey, RBG, how would this motor survive being used to push a small boat with a long tail mud motor kit attached? I've seen a couple of people {perhaps even yourself?) say that stock motors work best for this purpose, and that performance-built motors used like this don't live for very long . Apparently it is because of substantially higher sustained RPM's being involved. 🤔 Any thoughts?
Thanks for the video. 👍
