Another great video bro. Ive been thinking about ordering from volts. I watch royaljz videos and I love the race and the cruise scene they got going on out west. I'm still waiting to see an old greyhound engine built on here. I've yet to find a video of one and I have a greyhound on my doodlebug and I love it. It's been holding up really strong
I have three Greyhounds. Two are utility engines and one is built for the minibike. They're just an odd clone with the unique side cover and five bolt head. Build them just like any other engine and all parts are available. Studz racing and NR Racing still sells the side cover and rocker cover gaskets.
My Greyhound has been sitting on the shelf since I built a 224. But today I removed my stock Hisun 196 and jackshaft from my second bike and put the Greyhound on it with a torque converter. Pretty strong runner for what it is.
Don't order shit from volts
That’s awesome that you’re helping those kids out!! He seems like a good kid!
You just keep making them faster and faster! 75 MPH minibike love this video!
Thanks!
That Royal JZ is a good dude. I've been subscribed to him as long as I have been a subscriber here.
Yeah he is, I’ve noticed he always looks out for bike buyers !!
Tells you what it’s worth, so you don’t get burned!
That’s what’s up!
Another solid video! I run 40 chain on most my bikes. Primarily because they are mostly off road and 8 inch rims. I like the durability and strength. Also they are forgiving as far as alignment.
Awesome video ! I absolutely love the bike ! I have to be honest , you made me a little nervous when you went across that sand patch in the road . Anyway , what a badass bike ! I e been looking to get one so I’ve been going through videos to see what type of bikes people are building and the mods that can be used . And another thing , not sure where you live but I absolutely love the area too . I unfortunately live in shit hole New Jersey so whenever I see videos of other areas of the country it reminds me to get out of this state because there’s so much more out there ! Thanks for the video and stay safe
Next stop the Texas mile. Great vid and bike as always. Thanks for sharing.
Thank you for watching!
Volts is getting love! If you see this Volts, I need that!
That's badass bro 💪
Love some royal jz, great channel!
Always Watching Sir🙋🇵🇭
Amazing! 75mph😮 Im now motivated to get the ball rolling on my $60 rolling chassis mini bike project. Thanks!!!
I gotta find me a cheap chassis. People are selling chasis for $300!
@chrisz.9974 I was selling mine for 100 decided to keep it after I seen how fast these mf go
Just fell from my little 212cc minibike and fractured a bone. Life is good
Burned tf out my leg with the exhaust header loading mine up 😂
ayeee shoutout volts minibikes in Compton babayyy
Glad you hooked up with Royal JZ and Volts! Good People!
No doubt!
wow like #4....that's the earliest I've ever been!...and this was the perfect timing for this vid as well, I was just contemplating the switch from a #35 chain and sprockets to a larger sized RK Gold 420MXZ
That's a little beast there.
Black your the best rock on
Thanks! 👍
Ohhhh now I know why your bikes are so fast....you have help from outer space.
That bike is so bad ass !!!! 😎
Great Scott
Very Nice!!!
Good video and yes you can make a time machine and the Alien can go with you! 🤣🤣👽👽
thats gotta be my fav build with that chrome flywheel housing BBBeast
Ya, I think it's my fav too...BEAST!!!
@@Black66 hellz yea man !!!!!!get em
All the fast bikes in LA don't run 40 chain they are all on 35 chain all the cruiser bikes run 40...Great Videos!
We prefer 35 chain because it's lighter which equals less rotating mass. The 35 chain is plenty strong too as long as you use a quality brand like RLV. We've used 35 chain on a 40hp GX390 engine in a go kart with no issue.
@@agkracing140thanks I’ve been working on my 212 mod 2 only lacking a cam
and possibly a little bigger valves. Running great now!
What is a good street tire I can get in 6” rims
Thanks for the input !! 👍✌️
35 chain really are to small tho I changed mine to 40 it can handle more power without breaking ijs
Not true 40 is better 35 too small for that power dudes a goof
Hell nah they run on 420
Good stuff
DUDE...! ⭐️⭐️⭐️⭐️⭐️
Come on man! Put a big cam in that monster so we can see it rip some more! Can't wait for a 300 series cam!!
Amazing
Excellent video brother!!!!
Sure would like to have a list of your build out
Thanks ! Check out the Mega Moto playlist for the entire build ruclips.net/video/wHIKyVU4oxw/видео.html
Just wondering where you got your motor mount spacer. I was think about doing a predator swap on my mega moto 80 and dont really want to cut off the oil drain bolt. Thanks.
Black 66, now those tires are speed rated for a little over 75mph🤣
Yes! LOL
Why do I always laugh so hard when it cuts the the thing blasting by at like 70mph. Can’t wait for spring so I can try mine out.
This this the video I’ve been waiting for just built a stage 3 212cc slapped it on a stretched mega moto and been playing with the gears haven’t found a good one yet. I way 240lb on a 6” wheel.
Switch it up to 10inch wheels n try like 63-68 sprockets on a 35 set up
Something I'd love to see is a Mini Bike frame built around a forklift propane tank.
Genius! I’ll do it!!!
Hey man, where did you get the front shifts for the bike?
Does the Coleman rb100 have a rear axel spacer, I bought one and it doesn't have one so I'm just wondering.
Dig that motor and the builds your doing. A lit of info covered
I've been playing with my ratio a bit. It's a Massimo Baja Warrior MB 200, it came with a 50 tooth on the rear wheel and a 12 tooth on the centrifugal clutch, (I can't recall the sizes of the 2 sprockets on the jackshaft off the top of my head). Initially I went with a 14 tooth clutch but it still would max out the RPM to early and I could only get about 48 mph. Next I dropped to a 46 tooth on the rear which got me up to about 55 mph before valve float occurred and obviously no more RPM at that point so I then installed a 36 tooth rear sprocket which put me at about 75 mph before valve float. I'm now running a 32 tooth rear sprocket, stock jackshaft sprocket sizes, and 14 tooth clutch. I should say that at this same time I went to some 25 lb valve springs which allow the engine to rev out to about 6,500 RPM and I managed to get a two way average of 73 mph (honestly it probably had a bit more in it but I'm still running SunF knobbys and based on watching them free spin with the bike on a lift I think I'm already exceeding anything close to safe by at least 25 mph)
With the 50 and 46 tooth sprockets the acceleration was definitely a lot harder. In fact it was brutally hard. As in wheel spin and standing the frt wheel straight up in the air while spinning the rear wheel. And that wasn't even a full throttle launch. With the 32 tooth rear sprocket it still accelerates very strong. Strong enough that a 20 mph roll on with another Massimo Baja Warrior MB 200 next to me (he's running a 10 hp Briggs and Stratton with a torque converter and a governor delete) I'm instantly 5 bike lengths ahead and adding another 5 bike lengths every couple seconds. It will still pull the front wheel off the ground by about 4 inches if I snap the throttle open at 25 mph. However...I cannot take off hard at all, I've got to wait till I'm rolling about 15 mph and then roll on the throttle. If I try to hit it hard from anything less than 15 mph the engine just completely overwhelms the clutch. I've done a couple clutch mods that made it better but I can still make it glow red hot without any effort. Unless someone knows of a clutch that'll actually grab and hold I'm going to have to go with plan B (I've got a 5 speed motorcycle transmission and clutch setup off a Honda Enduro). The engine I'm running is a Briggs and Stratton Vanguard Vtwin 479cc. Originally it was a 16hp but I've done a governor delete, a Kehein 36mm round slide, 25 lb valve springs, a set of headers and a minor port and polish on the heads. I'm speculating that it's around 22 to 24 hp and probably 25 ftlbs of torque. It runs a 1 inch crankshaft. Any ideas about a clutch that'll handle it, and also some street tires that will match the stock size (19× 9 ×8.50 I think) I'd really appreciate it.
You have any videos of that monster??
@@PAPII247 I've got one I took with my phone strapped to the handlebars that recorded before the carb swap and the 32 tooth sprocket. It's loaded on my FB but honestly the quality really sucks. Between my phone apparently having some issues recording smoothly if I'm moving much faster than the speed of snail, and the wind noise the video looks and sounds very much like I'm reentering the earth's atmosphere and it's not going very well. I'm trying to get some recording equipment to actually start a RUclips channel. The planned content will be mostly how to videos on modifications and repairs on minibikes go carts, as well as some late 70s through mid 90s Honda Xl, SL, XR, motorcycles and some Kawasaki 4 wheelers that I seem to be collecting enough of to qualify as a hoarder. There will probably be an occasional chainsaw (using/repairing) video and I'm sure there will be some firearms content as I have a small shooting range here on my property (out to 150 yards, rifles, pistols, and shotguns). There will be an emphasis on keeping all these projects as low dollar as possible while still getting results that are tangible. I'm no longer able to work a full time job due to health issues and since I'm relying solely on a VA disability check I tend to do everything myself, machine work paint, etc... and I think there are probably some folks out there who may be as broke as I am but aren't ready to give up on having fun, building stuff and riding like an idiot while grinning like a fool. When I was able to work I was a machinist, builder, and mechanic. I have been doing this stuff almost 38 years, spent many years as a engine/performance specialist at a Harley dealership, built engines for some pro drag racing teams (Top Fuel Harley based dragbikes) and spent some time as a research and development technician for Harley Davidson Motor Company, and did a few years restoring vintage raceways. All of this stuff was done with extremely smart and talented men teaching me and I feel that the knowledge these men passed on to me should now be passed on to others who are interested in such things instead of letting it die with me. Of course a significant portion of content will probably involve me doing stuff that's probably not a good idea (like going over 70 mph on cheap minibike tires that are likely at best good for 40 mph, or running myself over with an ATV. That kinda stuff is surprisingly normal in my day to day routine.
So if you'd like to see some pictures and video that is not good enough for a RUclips video my FB is under this same name and my profile picture is my beloved Gracie Doggy (RIP) wearing an olive drab Vietnam era booney hat. I have been recovering from an eye injury so I haven't posted much over the last month or so but hopefully there will soon be a video of me on the minibike doing a 70 plus mph speed run as well as showing off the new paint I did a couple weeks ago.
sometimes its worth reading the comments
you sir,are a creative monster indeed...a vtwin in a mini....you should make a vid of it.
one of the projects i have is a vintage snowmobile engine opposing twin im trying to stuff into a frame myself.
for the clutch,have you considered modifying a snowmobile belt tav setup? they take tremendous abuse being hammered by big cc engines yes?
ive seen smaller tavs setups too?
for the tires,im not sure,im running Dot street tires on 8` solid rims myself,at around 55 mph.
@@PAPII247 I now have a video that is on my RUclips channel.
@@RobsMusicBox I ran one of the generic 30 series TAV/torque converters on the predator 212 that was in the minibike when I got it and I loved it except for one problem, belt life seemed short if you ride hard with sprockets set up for high speed, and the fact that I'm 200 lbs. There are some bigger 40 series versions but after talking to a few people it seems like to get one that will handle the HP and load I'm putting on the drivetrain would be about $400 and I can't swing that on a VA disability check. What I did do was use some parts from a Chinese 4 wheeler centrifugal clutch, and some pieces of the centrifugal clutch I was already running, and ended up with a 1.5" larger diameter clutch that has 3 clutch shoes on pivots and uses a friction material similar to brake shoes. So far no slipping issues and I've put about 300 miles on it. As far as the Snow mobile TAV setups, I had actually considered trying one out but unfortunately where I'm at (south Texas) there aren't many snow mobiles around to pick parts off of and since I know very little about which ones might have parts that would fit where I need them to fit, I was leery of buying anything off the internet just to find out I can't use it. If I could get my hands on some to play with I'd love to try one out. The opposed twin engines are cool, I'm wanting one for a small airplane I want to build, called a "Legal Eagle" it looks kinda like a Piper Cub but smaller.
I would do anything to get my hands on one, sheesh wanted one since 18.

Hey black love the vids where did you get the clutch cover from?
From 3D .Check out the best clutch cover in the world video. The link is in the description for the cover. ruclips.net/video/76ppl4ZmbQQ/видео.html
Hey,
Do this. Take your cylinder head off and send it to David Vizard.
He will do a show on how it’s best modified. He will port the runners and optimize the chamber for area ruling with flow balls. It will pick up port energy and probably get 85 or better from that. Nice job.
Do you put lock tight on those sprocket screws for some reason mines from volts screws got ripped out
What’s a good clutch for a 53 tooth sprocket I got a 224 with a mod 2 cam 18lb springs I have 60 on rear and 15 in front and I’m hitting 55 I wana hit 60 mph
What's best to use as a chain tinchener on the 35t chain please get back to me
Im getting a 212 and a 30 series torque converter for my ct200uex / Good idea???? any worries???
Nice .
Where do you suggest buying a good solid clutch from that’s gonna last an I’m not talking 300 one lol
How I get volts to ship my sprocket it’s been 2 weeks and has been ready to ship for a little and nothing is happening can’t get ahold of the have even emailed them
Nice Stuff I'm surprised by the absolutely Steady Solid ride what Tires are you using ? what is the outside diameter ? Beautiful Toys and Great Location for it too Enjoy it 👍
04:23 DUDE!...... the Filthy Frank Alien in the background!!!!! lol
hey black66 what was the shipping time on the volts minibike sprocket and clutch? I ordered a clutch and sprocket 3 weeks ago and still haven't got it. I tried calling, emailing, dming them and no response back.
That is one sweet mini bike @Black66 I think its about time for you to open a shop and do custom builds. I feel confident that you would have a long waiting list from day 1! Now this is off topic however in my quest to reach speeds like you I am plagued with one problem which is out of round/balance wheels. Because you have done so many builds I wanted to ask you if you have ever had any stock wheels that were out of round or warped? The bike that I have been building for way too long is almost complete but my wheels are out of round, even when spinning them by hand it is pretty noticeable. My bike is a Realtree RT200 which is the same as a Coleman RB200, and nearly identical to the Mega Moto 212, minus the front brake and factory torque converter. Coleman sent me out 2 replacement wheels and they seem to be just as bad as the originals. I have replaced the factory tires with some SunF tires and replaced the cheap stock wheel bearings with some quality Japanese bearings but the wheels still wobble bad. Is this a common problem with factory coleman wheels or could I possibly be doing something wrong, or is my luck so bad that I have 4 wobbly coleman wheels?
I've had a couple wobble a little ,but nothing too bad. I did replace the Coleman CT200U-EX wheel with a MB200 wheel from GPS when I did the disk brake conversion on the Coleman. That thing spins true. Maybe you could put some nice aftermarket wheels on there?
Oh my word!!
Check out the Mega Moto playlist for more combos with this bike. ruclips.net/video/VbcpA0jdSIw/видео.html
I got a old rupp and my cousin was saying I could make it straight up chain drive, instead of the torque converter, but it goes pretty fast with just that, might have to check something like this out later
Check out the playlist. I have many torque converter and straight chain videos.
Man that bike scoots! Seems like the 40 chain handles lower power levels with high efficiency.
I love your channel but i just dont understand what the different size chain does. I do get the gear ratios and i always cant wait until your next video sir. 👍🇺🇸😎Roger
Let me know when you get that time machine built I’ve got some unfinished business to take care of 😁👍🏻
I found both of you guys at the same time lol
Have you checked out the Ducar 212 engine yet it seems better than the Predator or the 212 tolston
Where can I get the exhaust pipe
grandson has rb100 new wont start, suggestions?
checked kill switch, fuel, plug, air, not sure where to go next on the bike
Black 66, did this gearing setup seem really hard on the clutch at take off and lower speeds?
Yes it will, you will see premature clutch wear, with this setup you will want to get going at like 15mph pretty quick if you want it to last
So for this video that he uses does he use a 40T back sprocket and a 10T clutch sprocket
Does Black66 mod people’s mini bikes on the side? I’m on AZ I’d love his help and expertise
I like it
What forks are those? Is there a option with the stock 6 inch wheel and disk brake mount up front?
They are GoPowerSports forks. I don't think there is an option for the stock forks, but it wouldn't be too hard to fabricate a bracket. Check out the Mega Moto playlist for the entire build. ruclips.net/video/VbcpA0jdSIw/видео.html
I have a 212 hemi and its right out of the box .. when I tilt it back and forth higher sound coming from the side of the engine I don't know what it could be it sounds in between bits and pieces of something engine or something is supposed to sound like that I have no clue
can you shout out what type of brakes you got? i have a mega moto just like this one with a 212 predator but i need to add better/ hydraulic brakes and a front brake disk as well
Check out the Mega Moto performance playlist. It shows the entire build . There is a video in there with the front and rear brake install. The parts used are in the description of the videos. Thanks for watching!
Can u make a video about making the 420 predictions fast?
Yo what do u use to record the top speed while recording?
I use digiHUD on the phone along with the camera GPS and a Dragy performance meter for 0 to 30
Will 459cc fit on my coleman ctu200u
Very informative video PlehBOi! - 🤘🏽🇺🇸🫡
How do you deal with the vibration from going so fast ? Running into this problem currently and trying to find a good salution
This bike is super smooth at speed. I think it has to do a lot with the street tires and the balancing.
What size screws are the in the spocket
❤NICE VIDES THANKS FOR SHARING… Where can I get that style hoist? Or did you make it Thanks
Thanks! not sure about the lift I bought it used.
what engine mount is that? would my 224 predator be able to use it on the same frame? my after market carb doesn’t fit
Yes, the 224 will fit. Check out the Mega Moto playlist for the build video on this bike. ruclips.net/video/CyOjHi-WEdA/видео.html

what exhaust is on that i have been looking for a center stage that will fit on my mm80
It's a cut F@ B pipe. Check out the Mega Moto playlist for the entire build and the exhaust video. I think GoPowerSports has a center exhaust for this bike. ruclips.net/video/VbcpA0jdSIw/видео.html

So this beats the ebike. Looks like you could use taller handlebars. It appears they almost hit your knee pads. Are the lower handle bars comfortable?
This bike is comfortable to ride. I'm a smaller rider . The bike fits me pretty good,
This is sweet! I’m looking to get a good Minibike, but I’m not super handy, so I want to try to find a good one, do you have any recommendations?
@@Black66 I found some good ones on tractor supply co. Are you able to mod any of them, or only specific ones?
Nice job, I believe this bike is my fav.
Since you have been doing this much longer than I ,,I can use some help, I only have money for one and I want a stage 2 kit. (No more)what bike do you think is the best , to built on for speed/power?
I’m thinking the mega moto
I’ve had a Coleman there good, I just think the frame could be tightened up a bit.
Any input would be appreciated greatly!!! ❤
Thanks! The Mega Moto 80/105 is my favorite modern bike. I like the way they handle and ride. Especially stretched out a little.
Yes they are on the small side but you can still fit big power in the small frame with a small block engine or even electric.
@@Black66 what electric mini bikes motor + ESC would you say is good? I work with high end esk8 motors a lot.
@@quinnfoster1234 I have only built three e-bikes. A QS90, QS120 and a Kunray 3000w . The three e-bikes are on the e-nike playlist if you haven't seen them already. The QS bikes had EM controllers.
The QS stuff works fantastic for me but I like the new controlles coming out from electro and CO. The TRUMOTO Noisy Cricket.
How many teeth on the rear sprocket and front clutch
How did you mount your gas tank
Question I got for you. I have Baja warrior trying to max it out what parts I need for wheelie and hit 70 to 100 mph Cruise bike
you cant do anywheres even close to both unless you use a belt driven Tav.
even then your stock warrior will go 52 mph.
start there,and work on a engine build for later install.
get used to riding it with the stock engine then swap and really FLY.
Please be safe and wear a Helmet.
Your shit so helpful man love to ride with you one day it be a dream man
Thanks, man! Happy I could help .
I have a centrifugal clutch for #35 chain and want to switch to #40 chain but want to keep my clutch. I can't find any sprocket that is for 40 chain but will also fit my clutch that is for 35 chain sprockets

@Black66 thank you, I will watch the series. I appreciate your help
I need another opinion. My mini bike hits around 45mph (its a doodle bug with a 212) and it feels like valve float is hitting. How big of a difference will 18 lb valve springs make? I also am wondering if anyone knows where I can buy a 50 tooth rear sprocket for a db30
@@MiataMatt I heard the 22lb would grind the cam lobes down more than 18lb.
I do long distance riding, so I don't want to get a new cam for it if I don't have to.
What setup do you have ?
No torque specs for sprocket bolts ??
Hey all, I just got my 1st coleman B200r. Wanting to engine swap. Was looking at the predator 224, 212 with a stage 1 kit, but recently saw a 301cc and got curious. What say you?
Can you do a video on installing hydro brakes
There are many videos on the channel about hydro brake installation. Check out the playlist. Thanks for watching! ruclips.net/video/VbcpA0jdSIw/видео.html
Someone please answer because I’m confused he says 75mph with one mod is tht one mod being 40T rear and clutch upgrade because from the looks of it he has plenty of mods done to it from the billet valve to billet crank cover, so I’d imagine he has billet parts upgraded cam etc? Is the “parts list” the parts that’s in the engine ?
Would this set up fit my Coleman 200cc? I just purchased the predator 212, and came across your video
