Suspension travel successfully eliminated... :-D
The point here is not to make the final outcome functional and better. This is followed because it is unusual, well filmed and fun to watch. Most of these projects, once they are finished, go to waste or recycling anyway. :)
.... and when the front wheel "come up" on the suspension travel????
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
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
Gonna need a spring loaded chain tensioner on the back sprocket chain when the shocks are compressed
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 dangerous transmission, you have to make additional protection over the chain, this one is not enough.
The rear chain tension is jeopardize by the suspension travel.
A little late watching this vid. Nice build but totally disregard the suspension travel front and rear. 😂
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!
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
Two words. CHAIN TENSIONER
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.
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
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
Yup
Should have just fixed the 2stroke much cheaper and easier also way safer, that chain looks lethal
There is a governer screw near the throttle lever on engine if you unscrew it youll have much better top speed
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.
i swear you were running it with choke on
If the front suspension is compressed it’s going to smack the front motor mount 🤦🏼♂️
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 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)
Definitely should’ve thought this through a lot more
A little bike with a big engine : cool 👍
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
20:52 i didn't see the chain protection there! Hahaha, great project. Congrats
I'd be worried about shock compression and clearance inherent than that ans a couple chain tensioner it'd be great
That dual chain system was making me nervous, glad to see that you added the guard.
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.👍👍
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
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
Dude the lil 50cc seems just as fast lol
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 😬
9:45 haha just love the fact that you raised your hands up with that expression "no comment". Love your video!!!
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...
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.
Hi have you not just deleted the front and rear suspension by fitting the engine and sprockets that way ?
svaka cast malo ljudi se ovako trudi ;)
I think the rear wheel is gonna hit the chain connecting mechanism while the shock is doing its thing...
Really it's a perfect work from a qualified person . Just need more protection for chain .. Still dangerous
Как не слитает цепь он звезду приварил к седенью а не к маятнику При сжатия подвески цепь покинет чат
There are quite a few questionable design choices present in this build
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!
homemade with industrial tools. so swag
10:50 David be like: A U PM!!!!!!!!!!
I think it was better before, faster and more fun with 2 stroke..😅 but it looks nice anyway.😊
It turned to dangerous at 13mins 😂, the exstra drive shaft next to ur knee and the weld this n that out of the way haha
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
Go pro kosy 😁
Awesome build, inspired something similar for me too
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.
*You upgraded 50cc to 200cc. Your title is wrong
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
i have to say the time and effort you put into this is nice i love to see it, but you have major clearance issues with the front of the engine mount and the steer wheel, plus the homemade jackshaft to the rear wheel, there is no room for the suspension to compress, and adult rider would go flying off the first time they put it down after riding a wheelie, with a kid it could be manageable, but first pothole or dip offroad would send them flying i would say the effort into this build was really good, but the technical aspect is horrid i mean just look how much that rear end dropped when you hit the gas while riding it. If you really wanted to make this work you would have taken the suspension out, i see trips to the ER and frequent tire changes in the near future with this build
Great job man, I am sure your brother is very happy.
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
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.
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
Парень со стальными яйцами 😁 если цепь от двс оборвёт будет аяяй
Great vid wish you had the original version to race it !!
That’s the coolest pit bike I’ve ever seen! Nice job 👍👍👍
He just kept going until it worked 😂💪🏻
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" 😱
With this new and bigger engine the pit bike looks badass
It seems very heavy..but heavy duty as well!!
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.
Surely the front wheel will catch the engine mount due to suspension travel??
That Jack shaft you made will never work properly, because you mounted it to the frame, but then your chain runs down to your sprocket that has a suspension to, and when you hit a bump, guess what, the suspense is going to lift up and make the chain come loose! Lmao.
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.😮
9:45 ”I’m a genius”
Definitely the best video on this subject!!!
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.
Nice sprocket they made looks tough as heck
Svaka cast Majstore
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
Chain guard GEEEEEEZZ
Very cool, but doesn't the chain fall off as soon as you hit a bump because it's not at the rear wheel pivot?
Dobro se trudim tako nastavi pratin te od 2019
no hate love the build but for the motor ad chain stetup did you not think of suspension travel
excellent as always. ''m going to call you Kimi as you remind me of The Iceman in F1
And why would you mount the pillow blocks on the frame like that and not the swing arm. When you have any suspension travel, you're just gonna throw a chain
Id start by making the bike abit bigger otherwise Rodney's wish could come true Lol
Good clean build
Sweet lil bike
I am sure little brother will be very happy🎉
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
Kad god bude udario na neku rupu prednji tocak ce udariti u motor. Ali svejedno svaka cast
Motor NAD ,engine 4 stroke .alat pemotong rumput.
Damn this bike must be heavy
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
hey, which glutch did u buy?? thank you
Так подвеска работать не будет не спереди, не сзади. Это просто попытка № 1 и всё. Доробатывай и доробатывай.
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! 👍🍀🇭🇺☝️🌞
Köszönjük
@@tothbotond5927 Nagyon szívesen! További sikeres szép napot kívánok neked, illetve mindenki számára szintén, erőben és egészségben, békében! 👍🍀🇭🇺🌞☝️
Nice concept but both those chains are going to fall off right away😢
Nice upgrade!
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
I think you should have went with a lower chain route, or did you do something about the chain loosing up? It looks like at 18:13 the chain gets very loose when you got on it. Is that loose or am I just seeing things?
looks cool save? not sure with those chaines swinging around :)
