It's always good to realize an idea If you jump, the rear chain will probably jump too and the chain guard at the front protects you from the chain, but not from the heat from the exhaust
I'm 14 and i have same little dirt bike, i put bigger carb from 85cc, low resistance filter, 70cc stroker kit, faster engaging clutch springs, sport straight piped exhaust, little battery driven fan to cool it, disc brakes, short throttleand a bit bigger sprocket for high speed, now it wheelies from the start and i managed to go 80kmh on it
Dude…I’m at a loss for words. From a guy who builds, invents and creates things I tip my hat to you sir. Making something like this work dependably is no easy task. Well done.
YesSiRr!! Mate... you are the Man!! Your doing some Kool stuff... I don't know why my Noti Bell didn't work... but now Iv caught up!! Lol!! Thankz again for sharing some Of your tips and tricks... really appreciate it. Take Care.. Stay Bless... and as always... Stay Safe out there...
Cool upgrade, a bit more fun. Only problem i see is the front fork/suspension, it has only 1-2cm travel before the wheel hits the motormount. On a dirtbike the front suspension has a lot of travel, so you should probably take a look at that. Interesting channel.
To improve more, level your carburetor. The way it sounds, it is flooding out some, or starving for gas. Also be sure your getting adequate oil flow. Your engine isn't level again, this may not allow the oil to be high enough to get splashes inside the crank case. Great build
why are people praising this video? (fully understand that its for a child) why did you just leave the motor running on choke? open the choke and that thing would have so much more power, i understand its for a little brother, but running on chokes gonna kill it, you can build a throttle stopper or something to keep him from goin full throttle, it would just need to have a good bit of throw, ive done it myself for my little brothers, or you could also just gear it down a whole bunch throw a bigger sprocket on the rear, and then gear it down even more (if you need to) on the jackshaft
i've seen a few cheaply made chinese pit bikes before, but this one takes the cake. bicycle brake calipers, and what looks like a modified bolt on bicycle engine!?! you might want to box in that frame since you have a lot more engine. you may start to get cracking in the frame otherwise from the extra weight and torque stress. edit; i was with you up until your jackshaft placement. you effectively eliminated your rear suspension. it needs to be as close to the swing arm pivot as possible to avoid the chain tension changing with suspension travel. you'll be snapping chains with what you've got here. at least now when it becomes a problem, you'll know why.
I'm taking to work at all fold up the first little bumpy hits yeah let's watch am registering so like a clown he'll get wider than a ball and bulshit I'm calling bulshit
Cool but one big bump and the back tyre os going to hit the bearings and the angle of the engine is going to cause an oil problem...but i find it good work because he managed to fit that big engine in that tiny bike
And here's the best part even if he did get all the power it would flex the shit out of his swing arm cuz he mounted his jackshaft right to the subframe😩
This was entertaining but i noticed a couple of flaws: 1. you used the angle grinder to grind the chain to shorten it which could have created a weaker spot on the chain 2.i noticed the chain next to the engine is quite loose 3.The engine is mounted metal on metal, which causes a lot of vibration and noise 4.The exhaust is really close to where the rider's leg would go, he probably won't touch it with his leg but it could create a lot of heat 5.not only the bigger engine, but you also added a lot of weight on the bike with the bearings, the 2 chains and steel parts 6.You removed the foam protection on the handlebars, which are meant to protect the rider in case of a collision with the head from an impact Despite these flaws i enjoyed watching and i still learnt some stuff and it ended up being entertaining.
Thank you so much for sharing! Congratulations on making a great video, great artwork and a fantastic end result! I wish everyone another successful day and of course strength, health and peace! 👍🍀🇭🇺☝️🌞
The engine is the right way round, hence the bike going forward ;) You are right though, it will break but because of the catastrophic design of his chain drive! Going from the back sprocket, which is obviously mounted on the swing arm, the chain goes to a fixed jack shaft, thats fixed to the frame. So as soon as you sit on it the stain will go very slack (as seen in the video)
I would of used a predator 212 but who cares, people underestimate the power u can make with a cheap 4 stroke, for a few hundred dollars u can really spice up those 200cc 4 stroke and it doesn't take a master mechanic to do it, there super easy to break down and rebuild and it makes really good family time with your wife son and or daughter. Great job
газ зацеплен неверно, надо за тягу гарбюратора тянуть, поэтому он и не может раскрутиться, ты тянешь за тягу поддерживающую обороты автоматическую, переделай как надо и поедет
18:13 The rear wheel chain connection does not fit the center point of the suspension connection and is installed at the top, so the chain stretches when boarding. The biggest mistake.
get that motor level down more,,, cranksharft will be starving for oil .those motors must be LEVELl,, everything then gets its proper lubrication,,. put a chain teninsoner on that chain ,,otherwise great video
It looks great that the intermediate shaft above the rear wheel can block the movement of the rear suspension. Not to mention that the frame and brakes may not withstand the increased load.
Only real problem I see is that the engine is mounted at almost a 45 degree angle so the dipper for the oil will be less effective meaning you might get barely any oil going onto the components of then engine
Svaka čast,ali ja sam uočio jedan mali "problem" sad nisam siguran da je nešto strasno jer naravno ti to bolje znaš od mene jer ti to u stvarnosti vidiš,uglavnom....mislim da ako naškoči na neku rupu sa prednjim krajem da ce nosač od motora malo da začeše po gumi,možda ni nije tako strasno ali eto.
the suspensions will work and the tire will hit the engine support, not to mention the chain swinging, and when the rear suspension works the chain will slack even more, which can cause an accident
pretty cool but need to work on that chain sprocket and suspension to hard of a landing will put rear tire rite into that bracket and lock up rear wheel, but I think its cool i would ride it for sure. good job
Ummm....whats gonna happen if the front fork....like moves? Plus the engine mounting angle is far from ideal, because of all the oil flooding the cylinder.
I'm pretty sure u could get that motor to run. Air, compression, spark, and gas. It's alot easier to troubleshoot these smaller engines. Nonetheless great job
look up any other video of a honda clone running they dont sound like that at all, and theres no transmission, the power loss is the way the motor is running, it really sounds like he just kinda needs to open the choke
Why did you not buy a big bore kit for the 50cc engine. 90cc that would fly. Still be light and 2T torque. Exceleration. Speed. Everything better that that thing that went in. Plus new kit costs £60.😮

Suspension travel successfully eliminated...

1 pothole and the fork will compress, the front wheel with lock up and you will go flying
Lmfao
Thought the same thing, as well as the rear wheel hitting the jackshaft bearings
It's always good to realize an idea
If you jump, the rear chain will probably jump too and the chain guard at the front protects you from the chain, but not from the heat from the exhaust
18:11 The back pully mount is digging into the tire. That's also why you rode so slow. Any faster and the bumps in the ground would wreck you.
Those pull starts and UTTER JUNK! My son has the same bike and I've replaced his 3 times but I've upgraded him to a KTM now! No issues!!!
I'm 14 and i have same little dirt bike, i put bigger carb from 85cc, low resistance filter, 70cc stroker kit, faster engaging clutch springs, sport straight piped exhaust, little battery driven fan to cool it, disc brakes, short throttleand a bit bigger sprocket for high speed, now it wheelies from the start and i managed to go 80kmh on it
That upper chain looks terrifying
i think the chain protection need to be much wider to cove 100% of the chain to be safe so no cloth gets stuck and pull the driver

Thank you friend for sharing your vlog about adapting the 200cc engine to a 50cc minibike. I am concerned about the chain guard. Great job.👍👍
A little late watching this vid. Nice build but totally disregard the suspension travel front and rear. 😂
9:45 haha just love the fact that you raised your hands up with that expression "no comment". Love your video!!!
.... and when the front wheel "come up" on the suspension travel????
Gonna need a spring loaded chain tensioner on the back sprocket chain when the shocks are compressed
20:52 i didn't see the chain protection there! Hahaha, great project. Congrats
To improve more, level your carburetor. The way it sounds, it is flooding out some, or starving for gas. Also be sure your getting adequate oil flow. Your engine isn't level again, this may not allow the oil to be high enough to get splashes inside the crank case.

Yup
A little bike with a big engine : cool 👍
That’s the coolest pit bike I’ve ever seen! Nice job 👍👍👍
homemade with industrial tools. so swag

Great job man, I am sure your brother is very happy.
Before i was like, ackkk the upgrade shouldn’t be too hard… and now I’m like, how much? LOL
Great video and great upgrade bro!
General purpose engines need to be mounted level for the oiling to work. They are splash oiled and will not work in this orientation for very long.
another disapointing think
There is a governer screw near the throttle lever on engine if you unscrew it youll have much better top speed
I noticed that the end you must have locked the suspension so it can't travel, because if you didn't, the chain would surely have slipped badly!
Sta se sve nece uraditi za rodenog brata BRAVO 👍👏👏👏❤❤
Really it's a perfect work from a qualified person .
Just need more protection for chain ..
Still dangerous
Dobro se trudim tako nastavi pratin te od 2019
That dual chain system was making me nervous, glad to see that you added the guard.
Cool but one big bump and the back tyre os going to hit the bearings and the angle of the engine is going to cause an oil problem...but i find it good work because he managed to fit that big engine in that tiny bike
Love your use of protective gear throughout the video!! Messing with bikes is fun, but so is staying safe! Cheers!
Definitely the best video on this subject!!!
Was probably faster with stock motor lol
lol
This guy says stupid he didn't bypass the governor he's probably getting a quarter of the motors actual RPM range
And here's the best part even if he did get all the power it would flex the shit out of his swing arm cuz he mounted his jackshaft right to the subframe😩
@Lane AWD lol powerband on a 4 stroke?
@@tiemenjansma4685 a powerband exists for every engine, it doesnt matter if its a two stroke or not
svaka cast malo ljudi se ovako trudi ;)

Dude deadass forgot to turn the choke off that's why it's not running like it's supposed to these things can easily go 40+mph* with right gearing
Parabéns Rafa agora os vídeos vão ficar top
I am sure little brother will be very happy🎉
Definitely should’ve thought this through a lot more
Very dangerous transmission, you have to make additional protection over the chain, this one is not enough.
Let we get him 2M be the end of the month😊

Nice! You should put that motor in an old motorcycle. Everyone has some old dirt bike from the 70s that doesn't run. Slap that motor in there.
excellent as always. ''m going to call you Kimi as you remind me of The Iceman in F1
that thing is gonna break so quick, engine is facing the wrong way and that your suffocating the poor engine with that tiny pipe
The engine is the right way round, hence the bike going forward ;) You are right though, it will break but because of the catastrophic design of his chain drive! Going from the back sprocket, which is obviously mounted on the swing arm, the chain goes to a fixed jack shaft, thats fixed to the frame. So as soon as you sit on it the stain will go very slack (as seen in the video)
also, the backside of the motor is up in the air. All the oil is gonna be up under the piston.
If the front suspension is compressed it’s going to smack the front motor mount 🤦🏼♂️
Should have just fixed the 2stroke much cheaper and easier also way safer, that chain looks lethal
Super job 👍😁 bravo 🍾
Dude the lil 50cc seems just as fast lol
I think it was better before, faster and more fun with 2 stroke..😅 but it looks nice anyway.😊
That was a dope little build would of got alot more power out of it too . That going to raddle every bolt off lol 🤣 sick !! Swap a ghost engine next
Good job. PS you look funny on such a small cross👍😂
I'd be worried about shock compression and clearance inherent than that ans a couple chain tensioner it'd be great
i love these, i want to have one in my trunk at all times, i love having something super small that has 8 horse power in it.
I would of used a predator 212 but who cares, people underestimate the power u can make with a cheap 4 stroke, for a few hundred dollars u can really spice up those 200cc 4 stroke and it doesn't take a master mechanic to do it, there super easy to break down and rebuild and it makes really good family time with your wife son and or daughter. Great job
Nice sprocket they made looks tough as heck
Say goodbye to the suspension system 😭! All I can say at this point is "JUST BECAUSE YOU CAN DO A THING DOESN'T MEAN YOU SHOULD DO A THING" 😱
Svaka cast Majstore
Вам нужно идти в компанию Лада там всё также делают как вы 😂
It seems very heavy..but heavy duty as well!!

18:13 The rear wheel chain connection does not fit the center point of the suspension connection and is installed at the top, so the chain stretches when boarding. The biggest mistake.
The chain doesn't stretch it gets slack.I doubt if roller tensioners would help!
Also the steel plate touch the wheel when he bounce or sit on it
It look awesome young man :)
Парень со стальными яйцами 😁 если цепь от двс оборвёт будет аяяй
The part he welded to connect the chains, IT'S Literally Touching the Back Tyre WHENEVER the suspension is Moving.
It May still haven't made the Tyre cut a part But, it will happen. A specially the Grаpples.
Buy it was really fun to watch,👍🏼
Weld the swing arm solid, weld er solid
Bro that’s literally the top speed of the 50cc anywyway 😅
get that motor level down more,,, cranksharft will be starving for oil .those motors must be LEVELl,, everything then gets its proper lubrication,,. put a chain teninsoner on that chain ,,otherwise great video
very cool modification bro
Kimi Raikkonen is a pretty good builder ahahah
That's a good brother makes his little brother a dirt bike.
Awesome build, inspired something similar for me too

Could've just did a big bore kit on the stock motor.
yeah because we need a child going mach jesus down the road
@@Rakyyy a whole engine swap for larger displacement to get stock motor power? If you ain't adding power ain't no reason for the whole project.
Y is it so slow? Should fly.

I think the rear wheel is gonna hit the chain connecting mechanism while the shock is doing its thing...
the small exaust is probably making the engine lose power you should make it bigger
the suspensions will work and the tire will hit the engine support, not to mention the chain swinging, and when the rear suspension works the chain will slack even more, which can cause an accident
pretty cool but need to work on that chain sprocket and suspension to hard of a landing will put rear tire rite into that bracket and lock up rear wheel, but I think its cool i would ride it for sure. good job
Ummm....whats gonna happen if the front fork....like moves? Plus the engine mounting angle is far from ideal, because of all the oil flooding the cylinder.
And let's talk about the breaks. There not gonna work that well. There not good to stop at high speed. There not rated for 7hp engines 😬
i swear you were running it with choke on
I'm pretty sure u could get that motor to run. Air, compression, spark, and gas. It's alot easier to troubleshoot these smaller engines. Nonetheless great job

1:01 eso sí que es para la modificación, hasta con un nuevo motor y milagro que es otra marca y modelo y con la misma potencia, eso sí me encanta
The sound is soooo rad! Too bad for the transmission, all that wasted power...
Dude there is no transmission only a centrifugal clutch
that sound isnt right, sounds like its running with choke on or something
look up any other video of a honda clone running they dont sound like that at all, and theres no transmission, the power loss is the way the motor is running, it really sounds like he just kinda needs to open the choke
@@jackmiller4706 Guys I know there is no transmission... I was meaning that!

Im guessing you are still learning, but please for next builds take notes from the comment section. There are a lot of mistakes on this build.

The inclination at which the engine was mounted will cause a serious lubrication failure.
