- Minibike goes 70 MPH/Predator 212
Changed out the rear sprocket on the minibike from a 72 tooth to a 60 tooth to end up with a gear ratio of 3.3 to 1. from 4 to 1, Predator 212.
Did the sprocket change to fix the problem with the chain hitting the ground due to the big diameter of the 72 tooth sprocket.

Beautiful bike my dude, nicely done 👌 one day I will have a bike equally as fast and then maybe one day we will meet up and race lol
Thanks! That would be fun. That's what it's all about is enjoying these things and having fun.
Iv got a 60mph on 8in tires turning 7000rpms on a manco thunderbird mini bike its a 212 non hemi 18lb valve springs sanded short turn 1.3 stamped rocker arms [stock style] just 1.3 ratio stock style carb with mixture screw bigger jet mod 2 cam arc rod and flywheel 32 degrees intake filter and 1in header pipe makes tones of power and has no problem moving a 115lbs to 60mph
@@madness_-yg3lw Nice build!
@@Black66 thanks lot of time and money in that build runs very well and very reliable i use a bicycle brake lever for my gas and on stock carb is very smooth and controlable i plain on posting a short video on what iv done and how fast i can go only probelm now is i blow apart the clutch bushings the brass one i have to install my cvt to solve that problem but i think i might be making to much power for it and will shred the belts my goal is 100mph i plain to swap valve springs and get a 24mm carburetor
@@madness_-yg3lw Keep working at it. You will get there sooner or later. I bet you will reach your goal with a clutch.

Best comment 👌
Damn... my thoughts exactly!!
How does this comment NOT have more likes 😂
Lol. You crazy
I made a mini bike here in old east England 🏴. Made the frame in my garage. Chinese pipe bender. Had local engineering shop make hub for my quad wheels . Got me an engine from internet. Took out restrictions.
Went like a bat out of hell. Meat loaf,. I’m old . Good artist…Cost me over £1000 . Sold it to a guy who cleared out my garage for £ 200. Before COVID . It makes me feel sad now I see your builds .
You have inspired me to make another. F-ck what the wife thinks. My son only likes PlayStation. . Thanks for giving me my life back .
Hello, I'm a retired mechanic and I made a very nice vintage style go kart, It took me 6 months of working everyday to build, I decided this is not for sale, Too much fun to own!
Wow, I'm pretty sure I saw a speed limit sign that said 25mph....Glad you're still alive to tell about it! LOL
I was going so fast I didn't see it lol
@@Black66 Ya think! LOL
That’s sweet. I’m building one now. Haven’t had one for 20 years since I was a kid. 70 on that thing is no joke. Most people won’t understand what that feels like on something with no suspension.
Thanks! Check out the playlist for many more builds and part test. ruclips.net/video/qE-aznzxMrQ/видео.html
You we'll have a Real Fun Time when those tires come apart !!!!!!!!! Have a good day.
Check out this video! I went even faster! This one has street tires. ruclips.net/video/xV8i59aGUao/видео.html
That is a beautiful minibike. That blue sets it off. Your videos are really making me want to get back into this hobby. I built several of these in the 90s.
Thanks! Might as well get back into it. No time like the present.
@@Black66 ya i have 2 of the coleman minibikes the bt200x and ct200u-ex. Trying to figure out which way to go with them. Build for climbing or speed.? I live in the desert now and usually run them on hills. My bt200x is heavier so doesn't climb as well as the ct200u-ex. So i love videos lile your for ideas and inspiration
@@goadmerle Maybe you could build one for speed and one for off road?
@@Black66 was thinking the same thing. The ct200u-ex for speed. Due to lighter frame
The Chuck Yeager of minibikes. Ran outta road!
LOL
Your right! I think it will go faster if I had more road
Man that's a sweet looking bike , love the paint job you did , and love the engine details.
I will soon restore the Ruttman mini bike i've had since i was 12, for the third time . It got trashed in salty hurricane flood waters this time around..
I would probably be most terrified of throwing a chain at those speeds - That would really suck .. be careful bro!
Thanks ! The vintage bikes are really nice . Good Luck with the restoration !
That’s so fast man! Be careful man we don’t want you to get hurt 🙏🏻
Thanks! You guys are awesome! I'll try and be careful
ruclips.net/video/TYp7SgO_FrU/видео.html
with those little tires on thier your lucky to be here partner
That's a slick chain breaker!
Wow. The beginning of video, how it flew by. 😮
Been watching for a while. Always great info here! I have a ct200u-exv and have been doing quite a bit to it. Keep the videos coming. Great channel man!👍
Thanks, I appreciate it. I'm always trying to figure out something to put out there.
RevZilla shoulda used this bike instead of their build to re-enact the dumb and dumber famous scene 😂
Very impressive back in 07 I had a 5.5 champion stock that was putting 60mph.
That was a fast bike! Especially a 5.5
When I was 12 I had doodle bug with a Briggs 3.5 that did 93mph... In the back of a truck...
Im your real pops!
Heck ya buddy you we’re flying out there super cool
That's freaking flying. Awesome 👍😎
You just need to do a "Rollie Free" for that last couple of MPH.
70 MPH 🤯🤯 You should do a video of a steering stabilizer going that fast!!
U dont need one if u have no speed wobbles
Awesome man i bet that one hell of a rush. It feels fast doing 50 on a Baja warrior fans imagine 70 on that little thing! Be safe tho man try to upgrade those brakes also when doing fast runs like this take somebody with you. Just incase anything happens you can have immediate help. Keep up the great work
Thanks!Good advice for sure. It's crazy, anything over 60 on that small bike feels like 100 lol Definitely does need tires and brakes.
YOU GOTTA TUCK DOWN !! At that speed, it matters.
Check out this video ruclips.net/video/xV8i59aGUao/видео.html
Bro that’s sick you should come down to Compton California and race it with other mini bikers they race every Sunday
Bring your full body armor!
Bro you had me scared half to death on that first run thinking you almost couldn't stop please take my advice next time don't pick a dead-end street LMFAO 🤣
Did you see the video were I actually went off the end of that road on the Doddlebug ? LOL🤣
@@Black66 no I didn't please send the link in this comment I am also currently investigating red beards garage on what exactly a stage 5 build is according to him he's using a predator Ghost engine on methanol interest in build indeed waste of money on the block though
@@spikemandan ruclips.net/video/6XT8DwdXvqM/видео.html
Good looking bike!
Thanks!
Very cool, I have been riding old Harleys most of my life ( I'm 75) now I still ride a 1949 Cushman motor scooter with a 14 HP Subaru Robin engine. I recently bought a Coleman CT200U-EX for Shi--t s and Grins. Just finished putting a torque converter on it and that tripled it's speed from the original Jack shaft. I'll probably stop there. Old bones don't heal as fast and young ones. Besides I've been riding for over 60 years. Keep your knees in the breeze and the shiny side up and the greasy side down.
Thanks! good advice! I have an EX I put a converter on also. Video coming soon.
ive got an old junky cushman eagle frame im gonna put a v twin briggs on.
@@frigglebiscuit7484 Yes!
Anyone else noticed the cow standing in the road at 9:35
Awesome!
my guy was FLYING
That is fast for that little bike. Nice job!
All right so I ordered a 14 tooth clutch for my 208cc Troy-Bilt with electric start the bike originally has a 36 tooth rear sprocket so 14 to 36 teeth the link you sent with the calculator calculated 53 mph hopefully 14 to 36 is okay and will work I have a nine and a half horse carburetor and a straight pipe I'm going to put on it
you have a drum brake and no secondary brake on a mini that you want to go 70mph. Good thing you are the test pilot.
Here you go! I went over 70 on this one. It has disc brakes. ruclips.net/video/xV8i59aGUao/видео.html
Absolutely amazing channel! You inspired me to build my own Mini Bike! Baja Dirt bug with custom plastics, lighting, and it's yellow. Goes a lil over 60!
Thanks! Baja Dirt bug is an awesome bike! Sounds like yours moves out !
what mods do you have on it ?
@@ducttapeandwrenches The links for the mods are in the description. Thanks for watching the videos!
@@Black66 thank you. how important are performance cams? i bought billet parts and was wondering how far i can go without a new cam.
@@ducttapeandwrenches you would probably want a camshaft for either low end torque or high end power
Just found you and subscribed. Awesome builds . 🇬🇧
Thanks!
What about bigger tires? Or just the rear, you'll get even more top end
Ya like some 33’s, just joking 🙃 definitely bigger rear tire for sure!!! Definitely cool little minibike
Agreed
14 inch in the back he would of gone from 66 mph to 84+
You've done a great job on that mini bike. I've watched you from the the start. Good tutorial.
Thanks!
That thing is insane
That's got to be terrifying
It is pretty sketchy
Wow that’s really fast.Great job.
Thanks! Fun little bike at that speed.
Thats fast for a mini bike. Be careful with those small tires. I've seen them tank slap out of nowhere and buck people off.
nice build. I like the gas tank.
Thanks! I made the gas tank out of a car reservoir tank.
We need you to put a wheelie bar on one of your bikes
Very impressive and is absolutely cool!
Thanks!
I ride my 2 stroke 70s mopeds to 60mph scary as fuck but u my friend u have balls of steel 2 ride that thinking bike to 70 mph that's sick b safe out there god always greats channel I love the way u test and tune no bullshit real numbers in the moped community every one is full of shit call out insane mph and no on board video keep up the good work I had one in the mid 80s when I was a kid so much fun enjoy
Thanks! I remember the mopeds . Those things where fun back in the day. Going 60 one one would be scary!
You have the cleanest Azusa I've seen yet dude.
Also what sized tires are those? They look like 5's. I want to ride 5" but I'm 6'4' 250 lbs. lol
Thanks!! I'm trying to keep it looking nice.
@@bigmacmillerlite8775 Ya, they are 5".
It is a small bike. They have a replica Azusa frame on this website that you can get with 6-inch wheels. Here is the link gokartsusa.com/mini-bike-kit-6-inch-wheels-2.aspx
@@Black66 Thanks for the link, but I'm going for the Cali style bike. Waiting for the GTS frames are back in stock and then going 5inch tire kit, Scrub brake, and Tilly 212R.
Once everything is in stock that is lol.
@@bigmacmillerlite8775 Right on !
I like the scrub brake stuff . Nice bike
Awesome build bro that fast on a mini bike
Thanks! Ya, it feels faster than it is on that little bike.
I bet it does bro
You're crazy the dad 😂 be careful of the cow! Lol
Did you saw the cow? lol
Every thought about adding a clutch band brake I'm going that route with my bad dog
No, i haven't thought about that. But that is interesting...
@@Black66 thier pretty cheap and stop really good my 62 golden pony had a scrub brake I added it and stops on a dime
Why do you not have a million subscribers
When I was 14 got my first mini bike 5 inch tires ,and it had a 11hp Briggs it was sketchy
This is incredible! I want to reach that sleep with a bicycle and I’m thinking of getting a 29 inch wheel bike. In order to increase top speed do you opt for more or less teeth? For the bike I want there is a 36, 40 and 44tooth sprocket. Thank you very much in advance!
That is insane
Check out this one, it got faster ruclips.net/video/xV8i59aGUao/видео.html
what's the frame you used on this bike? I love how open it leaves the center for anything you wanna upgrade.
Floyd and harry would of loved that!!
Arizona is beautiful!?!
AWESOME VIDEO
Those tires at 35 are fun, at 70 they should be the life of the party. I grew up riding a 330 go-kart with those.
That's what makes it fun. Doing something that shouldn't be done. My dad had a kart shop back in the '80s. Back then we went 30 mph with a Briggs 3 horse. Good times.
Death of the party more like it. KENDA tires at the least. I have a 3 horse flathead and I am hitting 45 anytime of the day. Used to run cheap tires ONCE until I had a rear tire blowout at 35 mph. Skill goes out the window because everything happens so fast before you realize it you are scraping yourself off the asphalt wondering where your bike disappeared to. 70 mph on them tires? No disrespect bro but you are ignorant. No other word for it.
@@cravenmoorehead5636 Yes! Need a good exciting tire blow out!! 👍🏼😀
That's insane bro 70mph on a mini bike. 🔥 I remember as kid having to fix links in chains. It was a pain in the arse lol All I had was a bench grinder to grind the brad down. I got good at it after a while lol That breaking tool is the trick. With out that good luck 😆🤣
Cool vid That thing rips 🔥👍✌️
Thanks! Ya, the chain breaker makes it a lot easier. Check out this video of this bike doing 72+
ruclips.net/video/xV8i59aGUao/видео.html
@@Black66 Cool checking it out now. 👍
For sake of stopping power I would go with a air heart disc brake, then get either a torque converter set up and use a belt of only 5/8" wide that way it will give you take off power plus a greater top end speed!!! I have been custom building mini bikes and karts for the last 47 years. I made go-karts and mini bikes go up into the stupid speed level. I used a 440 cc twin from a snowmobile with the compression so high that she preferred 113 octane and It was fun.
Thanks! I have quite a few other videos on the channel with torque converters and different setups. I like testing different combinations just for fun.
This bike won't have the combo it has on it for very long. lol I can't leave well enough alone
Help my mini bike guy's
I swear officer,your gun must be miscalculated this thing will never go 875 mph,it wont even go 45 mph,hohohoooo its not christmas yet is it
I just bought a Azusa mini bike kit. I got the 8” wheels and tires.
Sweet! Nice bike!
I'm surprised you let the old one get so dirty lol
I clean it really quick!
Real nice seriously my doodle bug db30 is hitting 46mph with a modified predator 212cc can't wait to reach those speeds
Doodle bug is a sweet bike!
I'm new to your channel, and you are a maniac with this ultra-fast mini-bike ... and that's awesome! Liked and subscribed! BTW, what kind of frame is that? Did you build up your mini-bike as a frame only, then chose all your parts by yourself, or did it come with an included engine, wheels, etc.? It's nice looking frame and a great color. BTW, yeah, you could've gotten up to and maybe past 70 MPH. You still had some top end left when you hit 68 MPH -- that's awesome! Way to go!
Thanks for subscribing! I bought the frame only . It's an old Azusa frame . One of the earlier models with the straight bars. I put it together in stages. There are quite a few videos on the channel with the different combos.
I know this is an old video but I'd like to know what the 1/8and 1/4 mile says. thanks
you get your catch can
Here is the link www.studzracing.com/product-p/coffinstyleclamp.htm
Where can I buy one of those chain tension kit that is on this bike
Dude, on my way to Aspen- I’ll trade you my Van for that beast!
Are you going to ride the minibike home? 😀
Wow a mini bike that nice needs electric start
I got a old Honda GX 390 it still works I want to make a mini bike with it we’ll see how it goes
I'd really like you to put a torque converter on that and with the gear ratio from the torque converter see how fast it would go
So with the 14 tooth clutch and 36 tooth rear sprocket with my 208cc engine bike will barely take off hits about 40 mph sounds like it's at idle when it's doing 40 and won't really gain above that unless you go a mile so my gear ratio is not good at all with my brand new clutch I want my bike to do above 60 mph I have a 208cc engine what clutch and rear sprocket do I need with a 10-in tire and 150 lb guy also if I put the bike on a stand so the rear tire spins freely the bike will rev out and spin the tire seems like 50 mph but not when I'm on it going down the road after half throttle it doesn't react
Wow nice build! Very fast and clean! I have a question for you. May I ask what specs are in your motor. I’m currently building a drag bike and went 60 mph with a 55 tooth sprocket with a 18 inch tall tire and a torque converter. I just changed it for a 70 tooth sprocket for 330 foot drags. The motor is mild but built extremely well with lots of precision. Everything is measured and clearanced to spec. But I’m at a point where I’m running out of motor on the top end. It has stock length billet rod. Stock crank. Flat top piston. 265 hot cam. Stock valve train except valve springs. Custom ported head. Stock valve size and all. And 24mm nibbi carb. The motor is very mild. I’m assuming with the stock valve size and camshaft size I have extreme bottom end and I get out on everybody by a bike length or 2 but catch me. Your motor seems to be built well no break ups through the curve. So my question would be is what specs would you recommend. I have a good chunk of money saved so I’m willing to spend. Thanks for reading through all this and great video.
Thanks! Your bike sounds pretty sweet! This one too is a mild build. It's like yours with the stock valves but it's running a 14cc chamber GX160 head with mild port work, a .012 thick head gasket with 1.2 ratio Rev rockers and 26 lb springs. I don't know if this head flows as well as a stock head even with the port work but with this mild build, the compression bump made this thing really snappy. It pulls pretty hard for what it is. I would like to try out one of Pauls's Karts GX 14 cc heads with his cam and carb. His TRINITY package. I think that would wake up our bikes lol
This one had the same cam you are running, the 265, but in this video, I changed it out for an even smaller 252 rattlesnake cam with the 1.2 ratio rockers just to try it out. It has a.020 ARC billet rod and an ARC billet flywheel. a Mikuni vm22 26MM carb with a header pipe. Nothing special at all. But I guess it's all about the combo.
@@Black66 thank you for reading my long paragraph and the quick response! I was looking into getting the trinity package. Seems like a sweet deal and I might wait for it to go on sale. Maybe I’ll try and get into contact with him and tell him my application. But great video once again and I love the bike. I have subscribed and will be looking for follow up vids. I’ll be experimenting with different combos and let you know the results. Keep up the great work. 👍
@@Black66 I have a question when you install the ratio rockers is there anything else you need to replace like pushrod length I'm building a motor now I a very mechanical inclined just don't know alot about the ratio rockers and push rod length
Sweet!! Nice work!
"It's scary on that little bike"?🤣🤣🤣🤣🤣 40 scary on that little bike, I can't believe you do 70🍸God bless you. Excellent work, you make some pretty awesome content.

2. What's the average range on a 1 gallon of fuel
3. Do you build & sell, if not where would be a good place near Long Beach, CA
Thank you in advance...
Cool.....
Yeah it definitely had a little more in it I believe with enough road you would be in the 73 mile an hour range that's crazy on a mini bike shit rolling down the highway in the 18-wheeler and see a mini bike pass me
I have the same sprocket problem on my cc100x if I turn too sharp.
I like it! How does it feel to be on that thing at 70mph with no suspension?
As long as the road is smooth is ok, but one little bump feels pretty scary to me lol
Love all your videos brotha... Could you do a video one day with a Briggs and Stratton 5hp (vintage engine) no one has really done anything or any videos comparing how a Briggs 5hp stands up to a predator 212. I personally have a few Briggs raptor engines that I'm buying race parts for and I would love to see how fast I could get it... Anyways keep up the good work brotha!
Thanks! Yes, I would love to do a video on a 5hp Briggs. We used to race them back in the 1980's with Horstman billet parts and Tillotson double pumper carbs on methanol. Good times!
Could you do this to a go cart with a 212 cc predetor on it?
