I have sort of a dumb question, ive been rebuilding motors for a long time, but what is the difference in the cam? What benefits does it offer? no, not being a smart ass here just curious
Only one way to learn im at the same point...find you a spare engine that somewhere...one that you can freely tear down and put back together to better understand and get more comfortable with the process...thats what i am about to do an engine swap and keeping the old one to teach myself
Ive pretty much mastered building the non-hemi 212’s thanks to these videos..Today I bought another 212 and noticed it was a hemi and im a little nervous about grinding the crank journal for the Mod2 Cam, but it really doesn’t look all that hard and it doesn’t look like much has to be ground off anyway. Hopefully all goes well
You do a excellent job of explaining clearly and very thorough ! Much appreciated ❤ Got rid of the 99cc Grabbed a 212, and about worn the engine out ! (6 mo)Running 6000+ grand without putting billet rod I did put a high rpm flywheel! But no rod ! Started knocking , and see a little color ring on my crank. Hope I didn’t ruin it ! 👍👍👍
Awesome build! You should really get a micrometer for checking the crank if you can. Calipers are better than nothing but micrometers are more precise. I don't usually trust calipers for less than .002 tolerances. Keep up the good work!
@THE PEDOPHILE EXPOSING BOUNTY HUNTER it's a small engine not a space shuttle. Taking a slight bit of material off is not going to make the engine "fly apart". You should look into that steel toe to the face.
Love it. From watching you guy’s I know I will be new to the sport. But I will now know witch mini bike and mods to do to mod the trail master mb 200 to me. You guy’s are great so awesome and have inspired me to get into a sport I know I’m gonna love. Thank you so so mutch. Be safe out there.✌️✌️✌️
Thank you for the detailed information on this project. As I'm in the process of building a stage2 on my 212predator. Again thank you for the details 🙏 ☺
You do know that using a clone head on the hemi bottom end is a exact one hp gain on dyno you only lose 5cfm per flow bench.......you can also remove the gear on the front of crank to freen up some rotating mass
Great video thanks and this is how every build video should be done in my opinion. Alot of people do alot of not needed conversation about parts and life stories that take way to long to get to the point. Thanks for the share I will be following and keep up the good work..
Great Video, I will be dropping a +20 Billet rod in my project soon as well. Thanks for the video. BTW, totally dig how you rotated the engine on the turntable at the end of the video at the same speed as your logo rotating on the computer screen... ;)

Omb says The standard bore on a Predator 212cc engine is 2.756". The Wiseco Piston #11132p94 is for a 2.756" bore, which means it will yield approximately .003" piston to wall clearance. This is right where you want to be, so provided your bore is good and needs nothing more than a fresh cross-hatch honing, it will be good. If your bore is larger, out-of-round, or the engine has already been run for a while with the stock piston, you will need to go with a larger piston. so do I need to get a larger piston for my 212?? It's a few months old and been used a lot.
Thank you for this. I want to build up mine. Where did you get and what is that coil you have? I like the red tubing? And what is the torque for the connecting rod bolts?
great editing and could follow voice instruction in video , but did not include the short bit on piston rings install. Why? is it bottom ring is 12 oclock position and the top ring in 6pm location ?
I purchased everything for a 212cc non hemi predator and installed it flawlessly I had my kart geared for speed to the point where we had to push it up to 45 mph before we hamerered down it went 97.7 average of three runs remotely controlled no Rider
i used to race in clone and flathead classes in gokart racing, 07 tempest for long and less bank tracks and 04 phenom for short high bank, with frame stiffener removed, i would turn my clone at 6300 with a 200 rpm drop for 20 laps and had great luck, verylittle mod, air filter and jets and header, it was fun before they let the builders get in it, now it is ruined for what was intended, budget racing, a person could by a clone from arc for 400.00 and go racing, now they cant be touched for less than 1200.00-1400.00 if you want to stay in the race,
Know this was 4 years ago, but I just had to add, I raced 2 cycle dirt in the late 70's into the 80's. Back then you could do just about anything to an engine you needed to make it scream before the foreign engines came on. It was a money game then, and that didn't take very many years to dwindle the tracks out of business. NOW, I'm 'cobbling' up these 4 'bangers' for the grandkids gocarts as much as I can HIDE from the wife! THANKS Red Beard!
So i had a question or two. Stuck inside like a lot right now. Figured I'd break out the mini bike. Bought a new 212 hemi. Thinking about doing a few things to it. I don't have a shop. I use a garage i rent from my apartment complex. So no work bench, no vise more importantly. So question one is, do i need a vise to set the bearing on the piston? And my second question is. Should i break in the motor before i start adding parts, or can i just do the stage 2 from the beginning before i even add oil? Personally im pretty sure i should just do the break in so i only have to hopefully open it up once. Clean it out and start replacing. But i figured I'd ask anyway since it's easy to just unscrew a few bolts and clean it out. I never know when I'll actually be up to the task of replacing all this, so when i am i want to just do it and get it done. Also i like the videos, its nice to get the proper torque settings and watch it happen all at the same time. But i would like to know what kind of power increases you can expect from each stage? Would help determine what realistically i would need vrs want.
No need for break in. Doing the build up when it's new is a lot easier cause its clean. Totally up to you though. If you want to see what it's like stock then upgrade for better results. Its pretty satisfying to experience the boost each upgrade gives you.
I weigh 240 lbs and a stock predator pulls me around just fine. Even with the Gov still in place which is a top speed thing. All upgrades I did was just cause I can and it's fun but didn't need any of it just to putt around.
what size tap did you use on the governor hole ? mine leaks i just sealed it with a bolt thats too small and gasket maker but it failed want to put pulse pump instead
Really well done video, everything you need and no BS! Just one question about putting the micrometer on the journal where the rod bearings go... I didn't understand why you need that measurement and what to do with it? Pre-fabing the rod and bearing on the vise allows the bearing to seat properly but what is the measurement for?Thanks, RBG's videos are top notch!
Red Beard's Garage thanks for replying so quickly. Awesome, I'm planning on building a mini bike here soon and building a predator motor. Love the videos man, very helpful.
Not sure if you've figured it out in the 3 years since this video or not, but on those type c-clips with the notches in them, just stick a little flathead in the there and twist. A lot more controllable, instead of flinging them across the room while simultaneously jabbing yourself in the thumb with the pick.
That piston was dirty when you initially put it in the cylinder but after the cam was installed the piston was clean and looked new, what's up with that?
Very informative! You just got a new subscriber! Hopefully you respond to your followers that have questions! Btw cars and cameras, and go power sports mentioned many of times.
I'll tell you the easier way. Damn RBG. Making everything so hard haha. Just look at the valve cover. Usually shiny alum is the Non-Hemi. The Hemi looks more dull.
@@1MACVSOG1 Really not a big difference. The Hemi would basically have a deeper grove on the top of the cylinder. The Non-Hemis are usually more universal and easier to mod, however.
Did the kit not have the correct valve springs , or a new crank seal? I guess its ok to use the old tappets with a new and different size cam. I'm starting with a stock 212 predator , Is there a previous video I should have watched ?
That's the Porter Cable impact driver right? That's the one with the quick release Chuck? I have that one and absolutely love it it makes small engine work ten times faster which batteries are you using with it?
Was wanting to know what I needed to do to my predator 212cc along with removing governor? Just change flywheel and springs or was there something else? Just ordered torque converter also so I’m ready to see the difference.
Anyone had success with Makuni carb on mini bike. I can’t get it where throttle response is worth a crap even with different settings on it. It goes faster top end big time but definitely not running right.
Just ordered my stage 2 kit, used your discount code. I have a brand new hemi 212, never fired up. Should I break the engine in before doing this install? Would it harm anything to install stage 1 and 2 before first cranking up the engine?
Cool video, I'm thinking about building one but it's a non hemi, i want to put a .308 cam in it says set it 34 deg btdc do you know what they mean, are there deg marks on the gear? The diesel engines i build do
Nice build! Only thing I would advise is to use an actual micrometer when checking bearing clearance. Plastigage is a good alternative to buying precision measurement tools, but micrometers are fairly cheap these days and if you can get a mic on it you'll get the most accurate measurement (often down to .0001 on a quality unit). On that note; Also remember to measure all your parts at room temperature without handling them too much. Hot parts and/or mics will produce inaccurate measurements. Some of this may be overkill on an engine like this, but good building habits will help you in the long run. How much (ballpark) do you have invested in this engine? Can't wait to see it rip!
*( Paul's karts lifan 420) this guy knows his shit he is not famous yet but he is building a world record mini bike out of a trixed out stroker 420.. ck him out you will be glad you did..he answers any questions I have withen 6 hours of posting very helpful and knowledge base. tell me I sent you
hey red beard question I have a coleman 100 and 200 and a predator motor just got.. should I just modify 200 I mean everything and then modify predator and put it on coleman 100?? what I wanna do..make it faster....have two good bikes I mean air and governor and putting new belt clutchs on both..what ya think?? thanks
I would go with the predator on the 100 frame if it was me. Since the other one is already there why go through the work. Modify both engines and have some awesome bikes.
thanks red just what I thought..so should I take governor outta of them or just bypass the?? what is speed difference between leaving them in our out even with all the other mods is it worth it??? thanks red I appreciate any input...
If you don’t grind down the crankshaft ears would you get a knocking noise when the engine is running?...I just did this install but I did not grind down the ears on the crankshaft & now Im getting a knocking noise in the motor. I opened the engine up twice but didn’t see nothing wrong
I’m putting a predator 212 on my mobility scooter because the battery pack and the motor are dead what encouragement can you give me? Should I go off-road tires or go karts slicks I will be driving this downtown as a mobility scooter also. Thank you and keep looking up.
Red Beard's Garage Yeah, I reckon that would be a tad bit pricy. Lol. Those little engines have always amazed me, so i thought i'd ask. Love all y'alls videos Brother!
Hey Red beard or does anyone know, what size cup washers did you use for this 212? I'm ordering a whole kit and want to have the parts ready for my build.What's a good place to order the cup washers that you'd recommend?
Let me know if you like the video. Hope this helps someone out in there installation process. Keep on build!
It helps! Thanks Red Beard!
I have sort of a dumb question, ive been rebuilding motors for a long time, but what is the difference in the cam? What benefits does it offer? no, not being a smart ass here just curious
The Bearded Outdoorsman pretty sure it allows the valves to open more for more flow which means more Rpms
It lets the valves open longer and at different times in the timing
Red Beard's Garage check out smallenginecams. com
Started my new hobby this year on small engines and minibikes. Gonna stick with my hobby. Wish I would have did this a long time ago
You going to love it!
The display,layout and editing were all top notch on this vid ... Good Job RBG
Plus 1
Id trade the fancy editing for a start up after doing the build
I was just gonna buy the stage 2 kit and put it on my engine but after watching this video, idk anymore lmaooo, you make it seem so complicated lmao
Only one way to learn im at the same point...find you a spare engine that somewhere...one that you can freely tear down and put back together to better understand and get more comfortable with the process...thats what i am about to do an engine swap and keeping the old one to teach myself
Why did you not replace the valve springs or mention it? When adding stage 2 is that not important?
Ive pretty much mastered building the non-hemi 212’s thanks to these videos..Today I bought another 212 and noticed it was a hemi and im a little nervous about grinding the crank journal for the Mod2 Cam, but it really doesn’t look all that hard and it doesn’t look like much has to be ground off anyway. Hopefully all goes well
I am nervous to grind the crank also let me know how it goes
@@andrellebeverly6340 not a problem…it worked perfect.. 👍 i just used a dremmel and took a little off…that’s all it took..
How much did you take off? I'm gonna grind mine today n don't want to grind too much
You got this 🇺🇸❤️
You do a excellent job of explaining clearly and very thorough ! Much appreciated ❤
Got rid of the 99cc
Grabbed a 212, and about worn the engine out ! (6 mo)Running 6000+ grand
without putting billet rod I did put a high rpm flywheel! But no rod ! Started knocking , and see a little color ring on my crank. Hope I didn’t ruin it !
👍👍👍
Wow dude. That was a beautiful install. 10/10 can't wait to see it unleash some power!
Its on the little red 2.0 video
Awesome build! You should really get a micrometer for checking the crank if you can. Calipers are better than nothing but micrometers are more precise. I don't usually trust calipers for less than .002 tolerances. Keep up the good work!
One of the best tutorial video i've seen on this. Great job!
I'll be using your video to build my hemi! Best video I've found. Thank you so much!
Man your work just keeps getting sweeter and sweeter. Man keep up the good work.
Your my go to garage for my new Hobbie with a 212 predator. Vids done very well. Not to busy with over-kill of info on subject of vid, nice
Awesome build, anyone else notice the new piston pop into the video at 15:20? Just thought that was funny, great video Greg!
Loved the way you torqued that flywheel nut to 54 ft lbs.
It's good enough
Just found your channel, great learning videos, good music. Other channels should take notes. I can't stop watching them. Thank You T.
The instructional videos and ones with Lonnie's Mom are my favorites.
+Noah Wolcott lol
Very well done. Watching your video even I could do it now. Thank you Red beard
someone who actually knows how to film a tear down bravo dawg
This video is going to help me out a lot, I had no idea to grind the crank shaft down to fit that cam, I just bought the kit
Some times you have to grind the center rod of the cam a little too cause the rod connects too.
when you grind on your crank for clearance for cam, you are affecting the balance on the crank. don't you get that re balanced?
@THE PEDOPHILE EXPOSING BOUNTY HUNTER it's a small engine not a space shuttle. Taking a slight bit of material off is not going to make the engine "fly apart". You should look into that steel toe to the face.
If I were to spend that much time and money, I would definitely rebalance.
@@chancewindham1718 facts bro
These engines aren’t even balanced from the factory what’s a little bit of shaving gonna do not a single thing
I think it was already unbalanced
Very detailed oriented, One of the Best videos I’ve seen so far. Keep up the good work!
Love it. From watching you guy’s I know I will be new to the sport. But I will now know witch mini bike and mods to do to mod the trail master mb 200 to me. You guy’s are great so awesome and have inspired me to get into a sport I know I’m gonna love. Thank you so so mutch. Be safe out there.✌️✌️✌️
Great video. Just wondering if grinding on the crank caused any imbalance at higher rpm?
Building a stage 2 predator hemi today. Thanks for the great channel, and great build videos,red beard keep up the good work!!
You are the best when it come to understanding my mini bike and what it capable of I love how you take your time to explain everything!!!😎💯🤞🔥
Thank you for the detailed information on this project.

You do know that using a clone head on the hemi bottom end is a exact one hp gain on dyno you only lose 5cfm per flow bench.......you can also remove the gear on the front of crank to freen up some rotating mass
Do you mean having a hemi block with a non-hemi head?
Great video thanks and this is how every build video should be done in my opinion. Alot of people do alot of not needed conversation about parts and life stories that take way to long to get to the point. Thanks for the share I will be following and keep up the good work..
I forgot to mention as well. I will replace my flywheel though. I’m putting in a Baja Three Magnet with a coil so I can run a light bar on my go kart.
Great Video, I will be dropping a +20 Billet rod in my project soon as well. Thanks for the video.
BTW, totally dig how you rotated the engine on the turntable at the end of the video at the same speed as your logo rotating on the computer screen... ;)

Did you clean the top of the piston ? It's pretty clean now .

I like the turntable the motor is on? Maker? And as has been said already many times, another great video.
I'd like to see the technique used for the paint job on the flywheel cover. Looks good.
@ 5:02 illuminati confirmed
Ah ha ! ;-)🤙🦈
I don't get it?
J MAC rectangle with hole looks like Illuminati symbol
Good video, but why does the piston change from time to time, meaning it's new sometimes and used other times?
What kind of coil or plug wire is that? Looks a lot better than stock
It's a msd one I made. Should fire a little better
So i had a question or two. Stuck inside like a lot right now. Figured I'd break out the mini bike. Bought a new 212 hemi. Thinking about doing a few things to it. I don't have a shop.

How many RPMs is a motor prepared like this good for? Very impressive work....
7000
Thank you...
In a lot of other Mod2 cam install videos, I noticed no one grinded the crank down, just you. Is it necessary to?
+Andrew Swensen you have to when installing on a hemi engine
Red Beard's Garage thanks for replying so quickly. Awesome, I'm planning on building a mini bike here soon and building a predator motor. Love the videos man, very helpful.
you make it look simple to do the build the other channels make it look complicated
Not sure if you've figured it out in the 3 years since this video or not, but on those type c-clips with the notches in them, just stick a little flathead in the there and twist. A lot more controllable, instead of flinging them across the room while simultaneously jabbing yourself in the thumb with the pick.
That piston was dirty when you initially put it in the cylinder but after the cam was installed the piston was clean and looked new, what's up with that?
little brake cleaner doesn't hurt haha. Makes it look shiny when you put it in so you can see how much carbon built up till next rebuild.
Editing 🤣

I put stage 2 performance on my 212 i never took measure mints of the billet rod and I used a card for the fly wheel
Everything still running good
You need to adjust the valves so they will work with the new cam
Yep. This cam calls for 3 thou of lash
On both the intake and exhaust
What happens if the clearance between the rod and crank journal is not good?? Do you need a new crank??
You would either have to get a new crank or thicker bearings. If it's too tight you can get the crank turned at a machine shop
Red Beard's Garage ok thanks for the tip 👌👌
To add a makuni carb do the governor have to be removed.
Yes
How do you know if your Predator 212 is a "Hemi" or not? Just bought one from HF, didn't know there were Hemi options

Was this a kit or did you by the peace’s individually
2 different kits. You can get them in the links below the video
This was one hell of an *AWESOME* video!
If possible though, please please do a classic flathead Briggs next!
I have a few I need to do something with
great video i just got the same parts for my honda gx160 and a flat top piston, what kinda hp #s do you think?
That's the Porter Cable impact driver right? That's the one with the quick release Chuck? I have that one and absolutely love it it makes small engine work ten times faster which batteries are you using with it?

You don't have to do the flywheel and billet rod but it is recommended. I did a video on what you need to remove the governor
I highly recommend a billet connecting rod if you do the governor delete

@@jeremyclayton6579 might need to be rejetted....
I like your gas tank model, where can one get it from?
Was watching these videos and had an idea. Every build should show the motor running at the end so we have an idea of what it'll sound like.
Just ordered my stage 2 kit, used your discount code. I have a brand new hemi 212, never fired up. Should I break the engine in before doing this install? Would it harm anything to install stage 1 and 2 before first cranking up the engine?
+Andrew Williams I would break it in after with some high zink break in oil
Is it OK to knock the governor gear off the crank I have seen it done on other videos you’ve done
Yes, take it off.. it's less rotational mass..
Cool video, I'm thinking about building one but it's a non hemi, i want to put a .308 cam in it says set it 34 deg btdc do you know what they mean, are there deg marks on the gear? The diesel engines i build do
When seating rod bearings, do you have to pick the bearings while seating.
Also do you oil bearings when installing into block.
I see now when you installed. You oiled them. So do you oil when Seating them?
Nice build! Only thing I would advise is to use an actual micrometer when checking bearing clearance. Plastigage is a good alternative to buying precision measurement tools, but micrometers are fairly cheap these days and if you can get a mic on it you'll get the most accurate measurement (often down to .0001 on a quality unit).

Nice work. Love it. I do have one comment though. The music didn't sound the best because it was just looped
Wouldnt you need to upgrade the side cover to a billet one ?
Was the governor removed in this build. Did I miss something?
definitely remove your governor
Is it worth though? Does it go faster then a 420cc stock? Cause u can get a predator 420 fir like 300$

hey red beard question I have a coleman 100 and 200 and a predator motor just got.. should I just modify 200 I mean everything and then modify predator and put it on coleman 100?? what I wanna do..make it faster....have two good bikes I mean air and governor and putting new belt clutchs on both..what ya think?? thanks
I would go with the predator on the 100 frame if it was me. Since the other one is already there why go through the work. Modify both engines and have some awesome bikes.
thanks red just what I thought..so should I take governor outta of them or just bypass the?? what is speed difference between leaving them in our out even with all the other mods is it worth it??? thanks red I appreciate any input...
If you don’t grind down the crankshaft ears would you get a knocking noise when the engine is running?...I just did this install but I did not grind down the ears on the crankshaft & now Im getting a knocking noise in the motor. I opened the engine up twice but didn’t see nothing wrong
Im sure it would cause quite a bit of noise.
If you grind any material of the crank your bearings will wear quickly because your sending the crank out of balance
I’m putting a predator 212 on my mobility scooter because the battery pack and the motor are dead what encouragement can you give me? Should I go off-road tires or go karts slicks I will be driving this downtown as a mobility scooter also. Thank you and keep looking up.
How do you brake in your engine? , do you do it after new parts?
Hey Bud! Will you ever build an alcohol racing engine?
+Bryan Wayne probably not anytime soon
Red Beard's Garage Yeah, I reckon that would be a tad bit pricy. Lol. Those little engines have always amazed me, so i thought i'd ask. Love all y'alls videos Brother!
Lets see it Run. Thats what I was looking forward tooo
Hey RBG, love your videos. What do you use for lapping compound on flywheels?
When doing this stage.. should I also add chormoly pushrods??? What about rockers??.
Hello, I have a question, why do you have to run in the rotor since it is still mounted with a key?
Is this for the hemi or the regular. Also does this video go with the stage 1, 3, and 4 videos?
I just replaced my stock carb with a mikuni, do I need to also install a billet rod or will I be fine?
No you dont have you done anything else thoe?
Daniel Mariscal thanks so much and no just the new carb so far
@@arcticturd4969 you are good
Can you swap out the stock flywheel in a predator 212cc for a billet flywheel but leave the stock cam and stock rod and get a faster bike??
So it did not show governer removal, also at first you installed the old piston, then put a new one?
Hey Red beard or does anyone know, what size cup washers did you use for this 212? I'm ordering a whole kit and want to have the parts ready for my build.What's a good place to order the cup washers that you'd recommend?
check out the amazon link in our description and you will find all the cup washers in there
Thanks Red! I didn't see a specific link to them, and I didn't think to check the you amazon section... THANKS MAN! Keep up the awesome videos!!
Is this pretty close to the same procedure on a Hisun 196?
Do these kits work on a non hemi?
15:19 What happened to the Old Piston ? All of a sudden it's Shiny and New looking
