- MASSIMO MB200 Re-jet equals more speed?
Baselined the MB200 mini bike for top speed and zero to thirty and then Tuned and changed the carb jets to see if we could gain any performance.

I learn something with every video. Thanks for the production quality!
Thanks!
I have this frame. It's currently fitted with mostly stock internals 212 hemi minus a governor. I've only added an intake, header, 22lbs valve springs, and a go power sports stage 2 stock appearing carb. I've coupled the engine to an ebay 30 series torque converter but added a juggernaut and a nice rotary belt. Running a 10/60 420 sproket set on the stock 19in tires. The motor is old and tired, has the original spark plug in it, and was on this bike when I got it, a year ago! I've beat the hell out of it. She still manages to pull (in north central Florida) a constant and reliable 45mph! But now, I have a brand new predator 224 sitting on the bench....
The MB200 definitely sounds alot better with the re-jet, Awesome video dude!
By the way, Nibbi has a flanged carburetor for the standard VM22 intake. In sizes 24mm - 28. I got a 24mm off of Amazon and it rocks.
Great info .........thanks for the schooling....gotta love AZ we live there also ........
Thanks! Check out the playlist for many more bikes on the channel. czcams.com/video/jHf9yJmaZLA/video.html
this bike is sick!
Yes finally the mb200 video I am so happy😊 💪🙏
Thanks! There is more coming.
I bought that same carburetor but it idles to high.I’m going to have to do what you did.Great video.
Crazy I bought my mb200 off Facebook off some guy it’s currently topping out at 51 😭
Your new neighborhood is nice. Curvy streets, some undulations. Not much level road for speed testing, though!
I don't usually do speed tests in the hood unless its a slow bike and doesn't need too much room to get up to speed. I have some nice flat areas that are out of the way that I go to for speed testing.
Where is this bike now? Just picked one up and have been following your coleman build but its really cool to see the exact bike being built.
I have the same bike with a straight chain to 60T sprocket and a stage 1 kit. Got 50mph hour out of it with a 5 sec 0-30
Damn you have a lot of bikes
THIS 👌👌👌
Perhaps that engine has a rev limiting ignition coil....I have never personally encountered one but supposedly they are becoming more common and I was told there is a way to visually identify them
I have heard people talk about those. I think you will like the video coming out today. The MB200 gets faster.
Hey lemmie ask you a question. I recently changed out my stock cam for a mod 2 cam and added 18 pound springs and changed out the stock 50 tooth rear sprocket for a 44 tooth. Now I knew once i swapped sprockets it wouldn't have the same get up and go as it did with the 50 tooth but yesterday when i went to test drive it for the first time with the upgrades i did it took off really a lot slower than i expected. But not 100 percent sure the sprocket is the reason for it alone. I noticed i was leaking gas from the fuel line where i had clamped off the line at one point to remove the carb. The teeth to the locking pliers ripped the line so i wasn't able to floor it without it sputtering and wanting to stall out. Atleast i'm assuming that's why it was wanting to stall every time i tried to floor it ? I ordered new fuel line and it is on it's way in the mail but in the meantime i wrapped the ripped part of the fuel line with that white plumbers tape stuff in hopes it would atleast slow down the leaking enough for me to ride lol. Would a rip in the fuel line cause the engine to want to stall even if it is a slow leak ? Also the center bolt directly on bottom of carb bowl doesn't fully tighten anymore cause the threads got stripped so there was a leak coming from that bolt hole as well but i added an o-ring around that bolt to try and stop it from leaking. So that's really 2 seperate places that gas is leaking from and i basically slapped bandaids on the leaking spots in hopes it would temporarily last until my new carb comes in the mail. I'm hoping once new carb is installed it will run fine without the leaks. But yeah i just wanted to know if you think the engine wanting to stall could be from those fuel lieaks i mentioned or is it something else like i need to adjust the air/fuel ratio on the carb better or something else ? I want to feel the real power everybody talks about when putting in a better cam and springs etc but now my bikes slower than before i did the upgrades and that is disappointing lol.
Literally same thing happened to me did a stage two flywheel rod cam and springs and lost like 4 miles per hour and I felt so lost went from a 50mph bike to a 46mph bike :(
Yes, fueling can cause it to run bad. if you modify these things and dont have the extra fuel to support the mods or the bikes can get slower. You have to have a tuned carburetor and header to go with that cam and you will feel the extra power. A smaller gear will usually get you more top speed, but if you are using to small of a gear the cam wont get into its optimal power band. Some can get away with a smaller sprocket because they are lighter weight, have lower profile tires etc. Watch the next Coleman CT200U video and you will see what I mean. Or the Next Mega Moto video. I add a bigger rear gear and actually go faster because the engines are more in their optimal power band with the new cam.
if my mb is eating belts, is something not alighned properly or the chain is too tight? or wrong direction?
No valve float more rpm I'm running 22lbs on a stock cam & head. Am I hurting it? Eh, may be. The stock rod and flywheel haven't come out yet! I keep beating on it and it keeps running and running.
No, I would run it that way! Check out the next video with this bike . I do something Similar .
I really like your videos. I have the same bike. were you able to install a front brake on yours? If so where did you get. I don't need more go, I need more stop. Let me know.
Good vid boss I'm vext my brand spanking new 15.x5.00-6 street tire caught a bubble in the middle of it I bounced of my porch an apparently it had too mucho air in it smh any tips to get it put and or do u think I shouldn't drive
If that thing has a bubble it could pop while your riding
@@Black66 dang ok thanks I'm gonna change it back to the small city sLicker
Hey bud I have a question , I have a stock internal predator 212 with a vm22 and a exhaust , governor removed. I can’t get it past 42 , right now the needle is on position number two (from top to bottom) I’m assuming it’s a factory jet , I watched your vid on how to adjust the mix screw and then adjust idle bit it doesn’t even accelerate when adjusting the mixture screw. And on position three with the mixture screw all the way in it’s already at it highest , I turn it and it dies , like it’s being flooded . I’m assuming I would need a bigger jet correct ? My sons 196cc did react the way it’s supposed to , it’s on position two and I did adjust it out to richen the mixture and adjust idle after and it runs great , the 212 though is giving me issues ….any guidance is greatly appreciated
I would first make sure there is no leaks between the carb and intake. Sometimes They can look like they are in alighment from the outside but when you pull the carb off and look down the intake you can see thet the intake and carb are out of alignment sometimes. If that O ring isnt sealed between the carb and intake you will never be able to adjust that carb. One you know everything is sealed up and not leaking I would use a bigger jet. The 95 jet that comes with these carbs usually isnt big enough for the 212 unless you are at high elevation.
My son has a Massimo. He needs some help upgrading his. Can you help him some?
Hey I have a question so I have a Japanese version of that carb which I just got and it either will run for a few seconds or just floods I don’t know if the idle circuit is too much can you take a carb apart so I can see how it should look
Are a 15t clutch and 65t sprocket a good ratio for quickness with top speed? On 13 inch tires
Can you completely take off the governor?
I haven't been in the case yet. Only the external linkage has been removed
Can you send the link to this exhaust pipe you got?
The link is in the description for the pipe. Check out the playlist for more combos and bikes. Thanks for watching!
hey i commented before about rebuilding a vintage mini bike, im curious out of all of yours.. what is the most fun or i guess most practical for just cruising around town/neighborhoods. Thanks
If your talking big bikes, I like the CT200U-EX for cruising around town. Small bikes, The Doodlebug is the most practical and easy to ride for me. Its about the right size ,not to big not to small. The Mega Moto 80 is the smoothest riding bike I have ,but it is stretched and has street tires. Its not so practical with the racing clutch and the lower handlebars. It could be a good cruiser if set up right.
@@Black66 Thank you man, much appreciated for the thoughtful answers you put down in the comments.. Your videos alone are enough to teach just about as much as you need to know.. I've fell down the rabbit hole and watched a lot of your videos.. all the way from just getting that first mini bike to fabbing up your mega moto.. I know the skills aren't much but you do it so effortlessly and without issue.
@@PopeyesCreeper Thanks! For me, working on the minibikes is the fun part. It's where I can be creative and put my own spin on things. I'm learning something all the time with these things. The video editing part is the part that is more time consuming. I guess it's still fun in its own kind of way.
Thanks for watching the videos. I appreciate it.
Are these pretty much like the trailmaster mb200
Similar. The Trailmaster has rear suspension
Which app do you use for recording your data?
I use a Dragy performance meter for 0 to 30 times , digiHUD on my phone along with the camera GPS
Was that with the governor still on?
No, the governor was bypassed due to the slide carb. Check out the playlist on the channel for many governor removal and part swap videos. czcams.com/video/jjtfBiuCFOM/video.html
@@Black66 o ok thanks man just bought my boy one. Ill check out the video. Im just one but u got a sub from me.
@@interceptor90ifyThanks! Check out playlist . There are quite a few different bikes on the channel.
@@interceptor90ifyThanks , check out the playlist there are quite a few different bikes on the channel.
One word to describe a middle aged man with ten minibikes: Single! 😆 Am I right?
No but getting there!
hey what pipe is that you have on your bike
It's a Coleman CT200U pipe
Not that bad but not that good🥴
"Massimo"? What's that? I thought an MB200 was made by Coleman. 🤔
Coleman dose not make a mb200 . Baja motorsports started the mb200 bikes there was at least 3or4 different version made. Massimo came out with there after Baja went out of business.There is a new mb200 called a trail master mb200 that has front and rear suspension with torque converter and rear disk brakes all that comes stock. Hope this helps 💪🙏
Wassup , why when im at top speed like 62 or 63 n i get outta gas n press again it dont respond until i slow down
You probably have a fuel delivery to the bowl issue. Might need to vent your gas tank or use a pulse pump.
@@WyFoster u gotta link to pulse pump?
@@pbedrook You can find them on Amazon for like $10.
Aite 🦾 n wym by vent gas tank.? Put lil filter on top of it
