- Time to LEVEL UP your predator 212 cc non-hemi engine from harbor freight with performance mods using budget parts and the right tools for the job!
This video details some less expensive parts, why I chose those parts over alternatives, a few tips and tricks on a performance build for a 212cc non-hemi harbor freight engine, and the tools you would need to do a performance build go kart or mini bike riding engine kit.
The engine used here is a predator 212 which is a 212cc performance engine. This engine build is one of the least expensive builds you can do with your harbor freight engine whether it's for your race kart or a mini bike. I'm using one of these in my race mini bike, one of these predator 212 performance engines will be used in my racing go kart, and one in my race wheelbarrow. This can be considered a stage 3 engine by many and has no part work done to it. You can pick up this harbor freight engine for pretty cheap and I've blown up a couple in testing so it's nice to grab a new one quickly and near me. This is a 6.5 predator engine and the 212cc to hp rank is 6.5hp out of box. When you upgrade your predator motors to a 212 stage 1 you are opening flow. When you add further 212cc predator engine mods with performance parts, you are opening up to a much more powerful engine!
This performance engine build will go on a race kart for oval track dirt track once ready. With the performance carb, most signs I see call this stage 3 build. However, some people call it stage 2, and I even saw one person call this a stage 4 build of which there was only that 1. When you're ready to take your game above the stage 1 mini bike or off road kart engine kits then you can expect to spend at least close to $400 on parts to up your game.

I still need a few more racing parts like the cam .This is a great video I have to watch it twice.
We call 'em "cheater pipe", or "breaker pipe". If you have a heavy duty floor jack, you can use the handle to function as one. Thanks for the vid. Modifying my 100cc now, so much fun.
I thought that's specifically what floor jack handles were also for lol
Parts and tools for a quick predator mods and a performance build, nice 👍
Childish Concepts!!! Dan is a Beast! He is the truth. 100% good guy!
The Make It Loose Now Darn It Bar... is called a Snipe.
Shims eh..this is new knowledge
Love childesh concepts, great help from very knowledgeable guy.
That tube extension is called a “snipe” around here. You can get fancy and add a length to the name. People here use electrical conduit. EMT 1/2” x 1’, 3/4” x 2’ and rigid 1” x 3’ are in most guy’s mechanics tool set.
Be sure to de-burr the ends. Slipping off is not unheard of when those things come out. I add hockey stick tape to both ends. I sure you can buy it in a minimart where you are.
Cresent Wrench is an adjustable Wrench, you have open end or box Wrenches.
Thank you for this video... we appreciate you putting everything together and sharing.
Love watching these videos man and helping me know a bit more about my 212 build!
do you have a video explaining the gas cap vaccum and drilling a hole 5/32 to help prevent the vacuum? My bike bogs wot with my gas cap fully closed and when I unscrew it a bit it doesn't bog anymore but I run the risk on my gas cap flying off mid ride.
I'll also recommend Dan and Childish Concepts, go kart motors and parts, also 1200 open motors for Legend Cars as well!
Hey I bought the predator ghost 212 and the ultra light flywheel didn’t fit . A builder installed a billet non hemi flywheel on it . He said that the engine is a non hemi . Does this make any difference or will it cause problems?
Bro. U def deserve more subs.
Good parts list for a predator 212cc build!
I want to see this engine on an off road kart with a Juggernaut torque converter. Would probably be crazy!
Venting the engine can be done without a catch can. You just drill out some hole in your lower valve floor area.
Then vent with a one way valve out of your valve cover.
Venting the engine prolongs the life of the engine
Remember to make them fast and make them last...
A BREAKER Bar ! That long tool.Trev New Zealand 😇
Box wrench is that side of the wrench. Crescent wrench is the box wrench that is adjustable with the wheel. You could break that with a cheater bar but you are unlikely to break a standard box wrench.
Dans the man! Childish Concepts is one of my favorite places to order from.
Genuinely enjoyed this video you got my sub
Really interesting on how you mounted your catch can, I have the same exact one. Does it make a difference running it how you did rather than how it’s supposed to be?
Most would buy an adapter/lift for the valve cover and run the line from the crank case to the valve cover and then into the catch can - but I swap engines frequently. This keeps it all contained in one place for demo purposes.
@@megoingfast ever since I seen your video I've been running mine like that and it's a great idea 💯
@@MoneymanRome is there a how to on mounting it or you just went off how it looks?
@@ethanduke813 I have a video on my channel with how I mounted it, you can either tap the governor hole for a relief with a hose going to the valve cover and then a hose from the valve cover to the can, or you can tap the side cover or get the billet side cover and do the same thing. It helps a lot for cams with higher spring pressure to relieve the block. I cracked my first 2 blocks not knowing it.
@@MoneymanRomealright thanks ill check it out
Can I run mikuni carb, billet flywheel, governor removed, header pipe and 22 pound valve springs? Or do I run the risk of my rod exploding 😂
Can you use 26lb springs instead of 22 then not have to use a shim?
Subscribing and liking ONLY because of the intro. Just kidding thank you so much for this video
That tube extension for wrench is called "leverage multiplication tool". I have several & all are labeled like that :)
That's a good one. Sounds smart!
Ok so I think I need new rockers because they keep getting loose on my 212cc hemi.It has a bullet flywheel and a mikuni carburetor. I’m learning a lot on this video. I’m tired of adjusting my value lash setting.
Do you ever check the valve clearance, I got a feeler gauge at oreillys for 5$ they had 3 options make sure to get the one that goes to the smallest sizes
I like all the details you include 🤟🏾💯 great video. Wanna run against mine 😈?
Just making sure that aluminum flywheel can be used on a non hemi predator ? I’m trynna make fast bike on a bugdet
Hey man, I am doing a complete rebuild for the same exact engine and decided to do this build. I was making my list and at around 4:19 you said a part that I couldn't make out very well. It was right before the spark plug. If you get to this, could you let me know which part it is and possibly give me any advice on the overall performance and experience with this build? Thanks
7/16" bolt, for tapping into the oil sensor hole. The engine has pretty good performance, and is a setup for some pretty decent power as is - that you can take even further to stage 4 level with balancing the crank, honing the cylinder, porting and polishing the head and a few other steps. The cs grind cam is a 265 lift cam similar to the popular cm grind and hot 265. If you do not shim 22lb springs, you can change to 26lb. This is a fast build that is inexpensive that kicks out power giving a great engine build experience. The catch can can does not have to be bolted to the engine, that just made it easier to contain for me. Many people prefer to buy a spacer for the valve cover and run the crank case vent into the spacer. Jet size will vary on a few things, you may want to run between 120-135, depending so having a kit helps.
@@megoingfast Wow that really helps, thank you. I've noticed that some parts are out of stock in your links and the main part that I can't seem to find is the Mikuni carburetor specifically in 24mm and for a 212cc engine under $100. Would you have any alternative suggestions for a cheap build like this?
@@ayolz1588 kyn, black motorcycle, all-carb, ysmoto... Pretty much the same carb just different brand. Search "24mm carb" on Amazon.
@@megoingfast Ok cool. Thanks for the feedback and communication. I really appreciate it
@@ayolz1588 Hi...You Could use a bike Carb a used one of Feebay designed for a Honda 175 or 200cc it'll run perfectly & cheap as French fries..it's a Kihien carb your looking for & the Chinese bullet noppled on the end of most throttle cables hook right up.NO jetting changes required !. Goodluck .Try Craigslist or Feebay for a used carb from a parted 90s- 2200 bike.
So you said the valve shims were .060 What is the rest of the dimensions because of light search that size shim there's multiple dimensions
Stage 4 predator...why does it spit and sputter at wot? I have 22lb valve springs but seems like it valve floats at high rpm range..do I need heavier springs?
Hey man ive got the 28mm pwk i got a 120 already installed in it do i need to do anything else exept tuning do i need to lower the needle thingy?
Also I have had to clearance my crank shaft when installing performance cams. Billet rods not the problem.
I hat about alcohol or E85, tried it?
so do they sell just "plastic gauge" or do we strip it off a wire? What gauge wire do we strip it off? I imagine you can throw a big fat gauge on there or else itll squish out really wide and go off the comparison chart.

Wouldn’t duel springs help better then single springs?
Question
Needle postion ?
Main jet size?
Pilot jet size?
What size carburetor should i buy? And i got a 224cc predator.
Those catch cans on a mini bike are bs to me. Run all vent hoses together into a large id hose and up to a high spot on frame with a filter. Ive never had oil come out. I'd add a flat top piston to that build. Lighter too!
Why add extra crankcase ventilation?
Great video keep it up ! 😎
What’s the best jets to use for the nibbi
Why are you wearing that Helmet During Conversation??
Where does the low speed tube go.
How does a engine stock cam so 9k?? I have 22lb valve springs stock cam no govonor was removed and capped off but 6550rpm wide open on go-kart geared heavy 4.90 ratio. Stock carb with .38 high and .20 low
CS grind is a .265 lift.
I fs gotta sub that intro
hey hey nice video, do i need to get a other valve cover for the rocker arms got a honda gx160 let me know thanks :)
Depends on your adjustments. Possibly. If you are worried, then get the riser for the cover that has a built in hole for any future needed oil inlet and you'll be one step ahead.
Hey brother love your video ! I wouldn’t go with 8degrees timing on that PVL since it’s already time advanced . Besides that I love everything else keep it up God bless & childish concepts 🙌🏻
I belive the pvl fly wheel needs the 8deg but the billet flywheels do not
What size vinyl hose?
What was the total cost?
I have done a stage 4 kit on my predator but now my problem is my current clutch keeps over heating and keeps sticking.. any advice or ideas for a good high torque SS clutch???
Drum clutch the hilliard inferno fire can take some power but getting sprockets is a little difficult. Best for most mini bike applications. For disc clutch The gofasthp.com clutches are hand made and you can get help for your build. Actually may be able to get help and the right parts for either setup. Last clutch I bought from them, best prices out there other than a 2 disc from childishconcepts.com which is also a great place for help on a specific build.
@@megoingfast I bought a 3500 rpm Max torque clutch, and now have no problems...
i’m not sure if your going to see this but can you please do a parts break down video of everything to chose to have the most power for a predator 212cc non hemi engine cause i want to do the stage 4 kit but idk what to chose and there’s no video talking about this
Most power bored and stroked with welded billet head running on alcohol can run $3000 and get you 30hp. Once you hit stage 4 you have a lot of options to take it past the 20 hp limit, however these crank cases usually blow up at 25hp and need a lot of reinforcement. If you're looking at stage 4, the crank case from a tillotson 212r is much more recommended once at this level. Most all power upgrades for that build are custom fabrication and metal manipulation.
For a purchased kit build, Red Beards Garage RUclips channel has a build video. You will likely need to further research high compression heads, balancing your crankshaft, boring and stroking the engine, and port work on top of that. It's a lot more work than just 1 video. 😉
Searching thru amazon i came across the nibbi air filter carb manifold kit for 120 will that work even better on a non hemi predator 212 or does it fit different size engine ..let me know asap thinking about buying asap
Yes-ish for better. It has better reviews from people I know who run them in regards to tuning. Fits same engines, based on size you get.
DId you ever get it running? What was the outcome?
Not sure what you're talking about. I'm thinking I put the video together wrong or people are not watching it the whole way through. I shimmed the springs like stated in the video, works great. I've made more than just the 1 of these. This was made after running these guys. This is a base for a larger build and information on how to build higher output engines. Shows part names, list, tools, etc. Build ideas, etc.
@@megoingfast I just assumed you would show it's performance on a kart. I looked around at your videos and never saw it.
@@Toid makes sense. I made the video to answer people's questions they were asking me about what tools and names of parts to use when going above stage 1. Guess I really just stopped after answering the questions.
@@megoingfast I understand that. I've made similar videos. I was just curious, because I was getting ready to work on a predator 212 to put in my go-kart. I never heard of childish concepts, but I think I'm going to go ahead and give them a call sometime and talk to him about some performance upgrades. Keep up the great work
Should have used a colder plug, like a 6 or even try a 7. A 5 seems like it'd be too hot for this.
Unless you use ngk plugs..the lower the number, cooler the plug..
How much hp does this make
Struggling with jetting, got the same basic setup what pilot are you running?
37, needle middle position, thought I have that in the video. Been a while.
@@megoingfast you did for sure have a 38 pilot and 120 main. Thing is impossible to start. Took an hour of tugging to start., any ideas,
@@ratrodcourier8576 I just checked the carb to be able to answer the question since I forgot if it was the 35 or the 37 in there.
@@ratrodcourier8576 if you were able to get it to start, but very difficult to begin with, raise the needle up.
@@megoingfast I'll give it a shot. Think it has timing issues. And flooding on start up
Every time I buy a cam with a target rpm I can never get my bike to reach the target because I weigh 240. I have a cam that’s good for 7500 RPM I can’t get it to go past 68, I have a brand new 308 Cam that I’m afraid to put in it because if it doesn’t do anything, it was a waste of time.
Gearing
Kobalt makes a universal socket that works great for piston rod torquing
Exactly where I found mine on my first engine build 😅 I was looking all over the place and needed that day.
I’m looking to get a PVL flywheel for my Non-hemi Predator 212. I’m scared that it will not fit my Predator. Please let me know!
Search "non-hemi pvl flywheel". Lots of them are listed as non-hemi/clone.
@@megoingfast thank you!
Does anyone know what size oring he is talking about at 4:30
HEY MAN IM FROM THE OLD SCHOOL.
THE "LEVERAGE MULTIPLIER " IS
ALSO A
"CHEATER"
"POWER PIPE"
"BREAKER BAR"
LIKE THAT🤗🤗🤗🍺🍻🍻
I've found that I can do what I want to do with 6500 rpm, a Juggernaut CVT, and gearing and have a long lasting dependable engine that'll last for years. 55 mph on a 135 lb. minibike is plenty fast enough for me and no clearancing is involved with dropping an EC Carburetors .265 Bansai cam into a Ducar 212/Tillotson 212E block with a billet rod.
Can you show me carb install I ordered all parts I have a ct200u-ex v with full billet everything torque converter and slot of parts I just can't find anything to show install of carb
You mean the cable?
We call that a breaker bar where I'm from
hello, are these predator 6.5hp engines better than the cheap ebay type 6.5 hp engines
Depends. Lots for sale on there. Some are good, some are not. Some are Honda clones in full and easy to mod, some not.
Where did you get the carb at
Can you put the link or give me the link to the cam thanks
the billet fllywheel is the better option for hemi versions (for price) but for the non hemi pvl is better
Why is that? I’m about to order one of the other for a build
hey did you have to change the slow jet?
Nope.
good vid and info brOski
Breaker bar or cheater bar is what I call the tube extension on the wrench.
I also call it a cheater bar
We call the bar a snipe here in alberta canada usually on a 36 inch pipe wrench and the fattest guy around to stand on it
snipe, I like it!
Omg the intro songs is funny.I have a 212cc that I hooked up and it’s faster than the 420cc go karts.
Thank you
I always called them a breaking bar because it breaks the nuts loose
Why the helmet?
Chris fix but small engines version
The pipe you're using for extra leverage is generally called a cheater pipe. Could be other names for it but that is what I've always heard people in my area call it.
What size carb is it the link has multiple sizes?
The one shown was 24.
What size is the air filter?
50mm
How much are we polishing the piston?
Knocking off most of the texture of the surface, does not have to be 100% smooth. You are not taking off more than the texture. Not sure why they chose to texture the surface of the piston.
Thanks man love the video
Nice !!!!!!!!
Hey Question what valve lash did you use for the rocker arms?
.003
Cheater bar, also great vid man!
Is it too much power?
never enough
The Helper, or Breaker bar
Would 5.26” push rods work with the champion rockers
If you pull the guide plate.
Let's call it, help my algorithm in the comment section bar?
I subscribed cuz intro
How many ponies are stuffed into that thing?
First time. Got me with the intro.
It's a snipe.
Thats a break it bar
Cheaater bar
he sounds like engineering explained lol
I need help with carb plz
Cable install? Jet install? 38 low, 120 high, needle kept in middle piston depending on elevation for starts and temp. Throttle cable fit for slide carb. Slide manifold
@@megoingfast tuning mostly and all the ports on the carb do the 2 vacuum ports on top need to be plugged
@@chadpolozola8516 helping tune a carb remotely is something I can't help with. The ports themselves however, are not all open. Look inside, most dead end. The ones that don't dead end, put a clear tube on.
I built this motor abs itsv the craziest thing I've ever ridden on before I put the big carb it did 50 then I put carb on was popping wheelies at 30 I was scared to go full throttle plus it was bogging
@@chadpolozola8516 after running it for a bit, look up "how to read a spark plug". It might steer you in the right direction, but will not tell you which part to tune just give a base insight. Stay safe and have fun!
a snipe
That device is called a "cheater pipe".
