Always check ring gap. At least .004" per inch of bore. A 70 kit is usually around 47mm which is about 2 inches, so rings should have .008" gap minimum. Also, it's important to make sure the cylinder ports are chamfered. Many kits require you to do this. I know Malossi is higher quality but I still would have checked that. It's extremely important. I also would suggest removing the engine, as it's only a couple more bolts and allows you to put the thing up on a table where you're not crawling around on the ground. It makes it way easier and more pleasant to do the work. Although that just might be my old-man-back speaking...
This is what most of us in Europe run for a budget, sporty wheelie build. The 70cc Malossi cast iron performs well. Al tough a lot of people do prefer the DR70 cast iron above the Malossi kit. Both seem to perform about the same with the Malossi having a tiny bit more top end. With a full volume crank set, a 19 mm carb with a good expansion chamber exhaust like a Yasuni R if you can find one in the states, a bigger intake manifold and thicker reed valves or a reed valve kit this moped wil fly! It will throw you back without any effort. You can go a bit lighter on the rollers as well 6.5 is the sweet spot for now. Have fun, stay safe!

That video reminded me my childhood - before (and even little after 2010) those 50 cc scooters was a go. Almost every teenager in my country had one and we even had our own community. Imagine a dozen of scooters zooming through the streets in line, popping wheelies on a secluded streets, working on them with friends. Performance mods is one thing but the cosmetic was also important - two tone paintjobs, polished aluminium parts... Heck, we even had a guys with a sound systems built inside the storage space under the seat (built from one/two speakers and a car radio or amplifier). Now I'm a 30+ years old guy and I see scooters being used for food delivery and casual cruising to work but there is no communities like those from 15 years ago. And no crazy builds. And some of them have electric motors. Now hear me out - with the set up like this I think You should easly achieve even 60 mph! Also, if I were You, I would entirely throw out the oil pump and do the oil and gasoline mix by myself. Then, for the new cylinder set I would add a bit more oil for the breaking period ;)

Good job man! As a fellow 50cc rider i suggest you get a 21mm carb like a Polini CP21 or a cheaper PHBG21 from dell'orto, also Malossi reeds, intake manifold (21mm diameter) and a cone air filter would change the bike greatly without affecting reliability.
It is SO fun to hear these names for parts and carbs... I live in Norway and when i was like 17 (33 years ago) Me and all the guys got the 7HP or the insane 12HP kits for our mopeds with malossi and dell'orto parts!! I did not even know they were in buisness still. I had a Suzuki ZR 50 that i put a 12HP kit on with the carb and performance exhaust but it was so insane it twisted my frame and the bike became undrivable. it did 110 km/h top speed but with a slow acceleration. Bought a Suzuki 50 SL instead the chopper version and chilled down to the 7HP kit wich kept the frame from twisting
That's the thing, with these kits, everything from hills, to daily atmospheric changes change the jetting. You can be good with the jetting for flat roads, but go to pull a 2 mile hill and they will go lean. Like him, I was suggested an 85 jet for the 21mm and a 90 would still be lean going uphill. I even installed a 91-100. If I got it rich enough on a hill the flat roads were running super rich. Only thing I could think of was for one, the cable that adjusted the 2 stroke oil feed was constantly shrinking and expanding, alternating the oil into the feed. Not to mention the dang rear pulley even a brand new one, would get worn in no time and not change gears properly. No spring is going to overcome those pins inside that rear pulley half from digging into the slots they ride in; hanging usually in mid range gearing on the rear pulley, never highest gears or the lowest gears. Kinda like the "Throttle position sensors"; they used to get an area of the gas pedal that would start to glitch while driving @ 45 mph because that is where the gas pedal is mashed to 90% of the time. That wasn't a metal quality thing like with the rear pulley, but just saying the most used gear is going to cut right into that part of the rear pulley slots first and foremost. These gears are made for 75 pound people..... And going 2-5 miles tops. And flatlands....
The Honda Vision was the one that started it all for me. I was 6 years old, my then 15 uncle and his mate had found one in the bush, probably stolen and abandoned there for a long time. They showed up with that thing and asked if I wanted to try it, I'll never forget the terror and excitement I felt as I twisted the throttle of a motorised bike for the first time in my life. Now, 25 years later I'm still hooked to anything that goes Brum Brum. Spent my teenage years in Italy riding modified scooters to school, after school and anytime in between that, those were the days! Keep it up man, that was a great way to spend 40 minutes of my life 🤙🤙
My friend built a honda postie bike but turned it into a race bike with a 179 race motor. with manual setup and moto x handle bars configuration. thing smokes 400s like theyre not moving.
You did not only brought it back to life, you created a "new" scooter. Unfortunately this tuning is illegal in Europe, because when you change anything, the registration is no more valid and you lose insurance as well.
This was my dream when I was 13. BTW I'm 29 now. A friend of mine had a Honda dio ZX. The only thing we did is tune it to 72cc with a unrestricted CDI. A few adjustments on the vario weight. It was fast like a rocket. Because of the lack of money back then, I couldn't fullfil my dream to tune a Dio with a 125cc exhaust carbs and everything. There was a kit on eBay back then for 600€. That was out of my league for then. Now I make more than enough money but I live in a city , in another country, no garage what so ever.... I wish I had a little money back then. Good to see someone did what he wanted. Nice video mate
Cincys finest motovlogger hands down. Editing, content, commentary all is on point. I rode with you on my sumo before i lost my finger in my wreck, such a cool dude and your videos are only getting better and better.
Man this takes me back. Some 20 years ago I had a Gilera 50cc with the exact same mods! Different exhaust but the same engine parts. Polini and Malossi have the scooter secret sauce. Great video!
Wheelies on a scooter at 40mph 🤣🤣 For ANY two stroke engine to perform at its best ideally an expansion chamber is needed!! This REALLY HELPS them breath Properly ( yes they look strange but that is how they need to be, a Big expansion chamber small pipe out, it is a REAL science making them properly!!!! Quite complicated!!
Try it with the old center spring for the clutch it could be even more responsive. It just depends on every scooter. Btw that 70cc should top out at 110km/h if you lose the airbox
naaaah, airbox is the biggest friend here, cause 2t engine is so vulnerable about air "pulses" back and forward and amount of vacuum in the intake. Leave it alone, max you could do is drill some slightly bigger intake hole in your box. and naaaaah x2, honda vertical af-18 never gonna go 110km\h on malossi sport spec. Even much more tune-able yamaha jog will not. Around 75- yeah, maybe 80 @@TwoStrokeJ
A bigger carb and a new airfilter is necessary, as the engine is basically being suffocated right now. The scooter won't get any more complicated or any less reliable, it will just run better and make way more power. And you shouldn't worry about having to tune the carb, as it really isn't that difficult. You just pick the right jet, which doesn't take too long through trial and error, and then you adjust the air/fuel ratio and the idle. After all that your malossi kit should max out at about 70 mph.
I think this is the best video I have ever seen. I bought a Honda vision myself and I am putting all the parts that is in this video Ps: this is the third time i watched this vid
Nice vid man, this scooter (Honda Vision) was quite popular in the early 90's here in the Netherlands, this is also the time scooters became very popular because you didn't have to learn how to shift and because of the CVT it wasn't slow like older automatic shifting mopeds and a lot cheaper to insure then a manually shifted moped. Illegal Scooter/moped tuning still is a thing here but harder to get away with these days, damn cops! A bigger carb something like 18mm and a better intake&reed valve should make it even faster.
Getting away with it isn't hard, it just costs way more money. My looks-stock Agility 50 has been modified with EFI, so when the cops pull me over for dyno testing (rollenbank) I just don't poke the app on my phone that switches to the "sport" fuel map. Cops invariably know something is up, because it cuts off at about 5000rpm instead of 6500rpm and it usually shows up as 52-54 kph. Even if they take off the cover plate that would house the CDI normally, all they'll find is an ECU without its Bluetooth sticker on it. If they open the carburettor door in the bottom of the seat, they'll see an injector and throttle-by-wire intake. Mostly I can make the cops go away after arguing about how it's for fuel economy. Worst things I've happen so far is a cop breaking the quarter turn throttle handle, because he thought it was jammed by some sort of restrictor mechanism. And one that asked "so where's the carburettor" while staring at the fuel injector assembly. With the sports fuel map loaded, it does about 65kph, which is fast enough. I've done quite a bit of modifications, but mostly because my friend bought a new cnc lathe for his shop, so yeah custom final drive, custom camshaft, reveno clutch pack, it's mostly "because we can" kind of things.
@@fermitupoupon1754welk bouwjaar is je agility? Ik ben altijd nog 2t tot de dood dus injectie ben ik ver van weg gebleven, ben wel benieuwd wat voor prestaties/specificaties er deze dagen in zitten
If this is the original carb, you might wanna buy a carb that's 2 to 4mm bigger. A carb that's too small for the amount of cc's is also restricting A LOT of power.
@@TwoStrokeJ this is a common misunderstanding since a bigger carb does not have anything to do with the reliability of the engine. Those malossi cilinders are made for big carbs, so it would even be a good thing for the engine.
Also, old carbs are less reliable since they are worn more. It wouldn't be a bad thing to replace the carb to one that's the same size if you care about the fuel economy.
These things are really popular or at least were back in the day in italy, vespas turned into flying coffins, big blocks with bigger cylinders, and the ignition also made huge power if modified correctly, also put a bigger carb in, i think its mandatory if you have all that stuff in there, 125cc two stroke scooters were able to reach incredible speed and power, went up to 180 ccs
This really takes me back to the 90's when i was in high school, loved it. One thing to keep in mind when doing this, is that the scooter will now require a lot more maintenance than the standard setup. Which can get annoying if you drive it daily and are counting on it to get you places. The fun factor of a geeked up scooter is incredible though
@@EbonyPope stuff always breaks when you install parts like these. I knew several guys who broke quality crankshafts playing around like that. You're constantly having to adjust the carburator, replacing the clutch springs, replacing the clutch itself, the variator weights, valves break easily, etc. All that stuff wears, breaks and gets dirty at a faster rate. The number of work hours you'll put is ridiculous compared to a stock scooter
It's amazing how old machines have more support than recent machines does as to upgrading and finding parts for em. I can feel the happiness from that initial start when it literally started like a brand new bike man!!! I know how that feels and pretty sure had one that didn't start most of the time except when it's cold LMAO. Used to have this 80's honda cub that I ride around with before it got stolen man, I even put a 125 mixed kit on it and everything and honda parts rarely change over time so it's easy to freakin mod. This one takes the cake though! Nice vid man :D
Upgrading a scooter to achieve huge power gains is a challenging yet immensely rewarding endeavor. The journey involves meticulous planning, technical expertise, and a passion for performance and innovation.
Your 50cc Honda scooter looks very similar to my first 50cc scooter, a Honda Vision, which I bought somewhere around 1995 in The Netherlands. I was 16 back then, the legal age one is allowed to ride 50cc scooters and mopeds, nowadays a valid license is obligatory. What about the US, do you need a special driving license for 50cc? What is the maximum allowed speed for 50cc two-wheelers? In The Netherlands it was only 45 km/h and every moped and scooter was throttled,. either with a special cap or ring in the variomatic (the front pulley) and/or exhaust. The easiest way to remove the restriction was replace the exhaust pipe and change the vario weights, sometimes also the fuel jet. Unrestricted a lot of 50cc 2-stroke scooters would easily do 60-80 km/h, with a racing reverse exhaust pipe sometimes even more. Downside was it being illegal. What do your local policemen say about it?
Anytime I go with a new top end I definitely take the time to Port it since you already have it off and you gain at least 10 to 15% more power on top of the upgrade.
Great job J !!! But you have to break in your new , expensive top end. also dont wash everything dry. wash it just like you do the dishes. lots a hot soapy water. I use Dawn.
dont know a lot about you current exhaust but i can assure you if you get a yazuni R, yazuni c16, Yazuni c21 pipe you are gonna get it to go 50+ mph and even e bigger carb you can go even beyond that. Here in finland the moped scene is HUGE every single teenager gets their moped licence when they turn 15 so it is not that uncommon to see scooters going 60+ mph (the legal limit is 27)
Yep that’s awesome man! I am going to keep the stock carb for now for its simplicity and hopefully it helps keep the engine more reliable over time. Maybe some day I’ll do a build with a big carb
To be able to just look at a CVT for the first time and basically figure it out on your own…fair play 👏👏. The starter thing is a Bendix, so well done Mr Bendix
I think you got a really good build for the money, but there are a few small details I noticed that you should keep in mind for next time. Since you bought a cast iron cylinder this time, it will take a very long time to break it in, and if you don’t do it properly, the cylinder might seize much faster. So, you should consider getting an aluminum cylinder next time. Also, when you upgrade from 50cc to 70cc, the moped's crankshaft may not be able to handle it, so you should replace it with a reinforced crankshaft. If your goal is to do wheelies with it, you should also use lighter variator weights, as the lighter the weights, the better the acceleration. You should also replace the carburetor, because the stock carburetor often can’t provide enough fuel for a 70cc engine. And if you change the carburetor, you should ideally change the ignition as well, otherwise, it’s very easy for the moped to misfire. Additionally, you need to get an unrestricted CDI, as the original CDI is designed to limit the speed to 25/45 km/h. But other than that, it was a really good build for $645
I’m a 31 year old, I’ve been riding since I was 15, I had a 50cc Honda scooter about 15 years ago and this brings me back and makes me want one! - old father with a GSXR and a few other bikes, now craving a scooter 😂
you will need a bigger carb for more easy power. 15mm minimum for 70cc but 18 or 20mm will be great, and then play with air / fule mixture and you'll get better acceleration and pull.
be prepared to change the piston sooner since 70cc wears out faster and if you do alot of top speed pulls they wear out really fast, also a bigger carb will give you more power but this is as good as it needs to be
@wash.625 My father did the same swap for his Suzuki 50cc when he was young (50cc were extremely popular in Spain), and he always says that eventually, the motor brakes due to the difference of pressure.
@@miguybaltasar1111I am from croatia and scooters are still popular here especially piaggio and people tune them in all kind of ways and I did them too, 70cc really opens the power but it wears out much quicker which isnt a big deal since the piston and cylinder malosi is really cheap to replace every now and then
You should buy a tomos 49cc 5 speed moped/motorbike they are really good looking bikes and are quite good at wheelies and stuff Edit: they are also very customizeable from the bars to the 74cc kits and custom dellorto carbs, ive seen some that make 15hp at 74cc

Nice video man, im also in scooter tuning here in Austria.. i would guess you to switch the roller weights maybe all to the 5,6g then u maybe get better acceleration bcus the engine is more in to the power range at more rpm..
Your contents are awesome and seriously deserve more attention. I'm curious as to why big scooters with actual motorcycle engines like the Honda ADV and Yamaha Nmax with either 150cc or the 300cc don't sell there in the US
Nice, we've been doing the same for years. Now we're up to triple and quadruple the original power and even more on the bleeding edge of kits and bespoke engines, up to 100 hp. I run an old, 1980s 70mm kit that is still in production and currently looking at some of the more exotic offerings for my 1960s scooter. Best of luck and keep on going faster! :)
gotta respect the efficiency- not MPG per se but the efficiency of the engineering of these little things- just purely made as devices to move humans from one place to another, nothing more. gotta respect it.
one more thing you can do is get a bigger carb, it will allow the engine to breathe better and you should get even more power since the air doesn't get as much resistance as before
The fact you just followed instructions from a text conversation to get this much power from first try, is just insane to me. Really cool video. This is the ultimate sleeper build lmao.
Great video brother! 71,000 subs and 1.4 million views, nice work! I love the vehicle community. I have a 7.3 powerstroke and through forums have been able to message with the original engineer of the 4r100 transmission that's in the truck and many other engineers of the truck and motor, it's crazy to speak with these OG's personally! It's amazing how great people can be and how much they are willing to help others. I have never taken my truck to a mechanic soley because of the community and culture around vehicles. I just subbed, I like your format!
Rings need to be letter side up and positioned with the gaps opposite of each other. If you install rings wrong it will smoke all the time and burn cylinder. And yes, always check gap by putting ring in cylinder, push down with piston to be sure it is in straight, then check gap with feeler gauge. Yama-Bond is the best. Grease the exhaust studs or they will be very hard to get out when you upgrade exhaust. Good job doing this on your own!! lots of little things people learn as they gain exp.
Got the same excitement watching this video as I did working on mine and making it fast. I also found that a racing CDI does wonders after swapping the cylinder. So does changing the carb. I went for 26mm nibbi carb. Keep in mind it drastically increases fuel consumption and your cylinder might heat up if you floor it for long.
It is really nice you had a personal shopper and mentor. I am out on the bleeding edge of stupid with a Jetson Bolt Pro. I got like, 5 useful YT vids and the rest I have to figure out. I am having a blast.
tip of the day: Use a pipe wrench to loosen the the 39mm nut on the clutch, by hitting the back of the pipe wrench on the ground while holding the pulley and clutch. Use this method when a socket isnt nearby.
When disassembling the cylinder head always remember to put a plastic bag or paper towel in the hole, ive dropped one of those c shaped pins into the engine once and almost debated taking apart the engine, luckily I had one of those telescoping magnets poles to use to get it out
In Denmark we had those 50cc scooters, and modded them like mad, with 70cc tune, carbs, needles etc, oh it was fun, getting them to do 90 mph with 10 inch wheels and breaks was optional haha

You can be good with the jetting for flat roads, but go to pull a 2 mile hill and they will go lean. Like him, I was suggested an 85 jet for the 21mm and a 90 would still be lean going uphill. I even installed a 91-100. If I got it rich enough on a hill the flat roads were running super rich.
Only thing I could think of was for one, the cable that adjusted the 2 stroke oil feed was constantly shrinking and expanding, alternating the oil into the feed. Not to mention the dang rear pulley even a brand new one, would get worn in no time and not change gears properly. No spring is going to overcome those pins inside that rear pulley half from digging into the slots they ride in; hanging usually in mid range gearing on the rear pulley, never highest gears or the lowest gears.
Kinda like the "Throttle position sensors"; they used to get an area of the gas pedal that would start to glitch while driving @ 45 mph because that is where the gas pedal is mashed to 90% of the time. That wasn't a metal quality thing like with the rear pulley, but just saying the most used gear is going to cut right into that part of the rear pulley slots first and foremost.
These gears are made for 75 pound people..... And going 2-5 miles tops. And flatlands....
@@Tsenngu 12 hp are not enough to make any metal twist. I'd say the problem was something else.
21mm is way too big for the engine and cylinder, 17,5 would suffice more than enough on this type of engine.
Absolutely, nice to hear someone knows a bit more atleast

The Honda Vision was the one that started it all for me. I was 6 years old, my then 15 uncle and his mate had found one in the bush, probably stolen and abandoned there for a long time. They showed up with that thing and asked if I wanted to try it, I'll never forget the terror and excitement I felt as I twisted the throttle of a motorised bike for the first time in my life. Now, 25 years later I'm still hooked to anything that goes Brum Brum.

You did not only brought it back to life, you created a "new" scooter.
Unfortunately this tuning is illegal in Europe, because when you change anything, the registration is no more valid and you lose insurance as well.
This was my dream when I was 13. BTW I'm 29 now. A friend of mine had a Honda dio ZX. The only thing we did is tune it to 72cc with a unrestricted CDI. A few adjustments on the vario weight. It was fast like a rocket.
Because of the lack of money back then, I couldn't fullfil my dream to tune a Dio with a 125cc exhaust carbs and everything. There was a kit on eBay back then for 600€. That was out of my league for then. Now I make more than enough money but I live in a city , in another country, no garage what so ever....
I wish I had a little money back then.

A bigger carb and a new airfilter is necessary, as the engine is basically being suffocated right now. The scooter won't get any more complicated or any less reliable, it will just run better and make way more power.
And you shouldn't worry about having to tune the carb, as it really isn't that difficult. You just pick the right jet, which doesn't take too long through trial and error, and then you adjust the air/fuel ratio and the idle. After all that your malossi kit should max out at about 70 mph.

Well done.
I think this is the best video I have ever seen. I bought a Honda vision myself and I am putting all the parts that is in this video
Ps: this is the third time i watched this vid
Nice vid man, this scooter (Honda Vision) was quite popular in the early 90's here in the Netherlands, this is also the time scooters became very popular because you didn't have to learn how to shift and because of the CVT it wasn't slow like older automatic shifting mopeds and a lot cheaper to insure then a manually shifted moped.
Illegal Scooter/moped tuning still is a thing here but harder to get away with these days, damn cops!
A bigger carb something like 18mm and a better intake&reed valve should make it even faster.
Exactly the same here in the UK ( also called a ' vision' here too) 👍 I still love these tiddlers.
the 130cc honda vision by dutchriders is a real death machine
@@kroketfilet It sure is 😎
Getting away with it isn't hard, it just costs way more money. My looks-stock Agility 50 has been modified with EFI, so when the cops pull me over for dyno testing (rollenbank) I just don't poke the app on my phone that switches to the "sport" fuel map. Cops invariably know something is up, because it cuts off at about 5000rpm instead of 6500rpm and it usually shows up as 52-54 kph.
Even if they take off the cover plate that would house the CDI normally, all they'll find is an ECU without its Bluetooth sticker on it. If they open the carburettor door in the bottom of the seat, they'll see an injector and throttle-by-wire intake. Mostly I can make the cops go away after arguing about how it's for fuel economy.
Worst things I've happen so far is a cop breaking the quarter turn throttle handle, because he thought it was jammed by some sort of restrictor mechanism. And one that asked "so where's the carburettor" while staring at the fuel injector assembly.
With the sports fuel map loaded, it does about 65kph, which is fast enough. I've done quite a bit of modifications, but mostly because my friend bought a new cnc lathe for his shop, so yeah custom final drive, custom camshaft, reveno clutch pack, it's mostly "because we can" kind of things.

Bro is making it Look easy
If this is the original carb, you might wanna buy a carb that's 2 to 4mm bigger. A carb that's too small for the amount of cc's is also restricting A LOT of power.
Yea I agree it’s restricting power, but I wanted to use the stock one to hopefully keep the engine really reliable
A 26mm Mikuni from the Yamaha DT 125/175 is a must-have. A no brainer.
A bigger carb won't reduce reliability unless it's lean or too hot.@@TwoStrokeJ
@@TwoStrokeJ this is a common misunderstanding since a bigger carb does not have anything to do with the reliability of the engine. Those malossi cilinders are made for big carbs, so it would even be a good thing for the engine.
Also, old carbs are less reliable since they are worn more. It wouldn't be a bad thing to replace the carb to one that's the same size if you care about the fuel economy.
These things are really popular or at least were back in the day in italy, vespas turned into flying coffins, big blocks with bigger cylinders, and the ignition also made huge power if modified correctly, also put a bigger carb in, i think its mandatory if you have all that stuff in there, 125cc two stroke scooters were able to reach incredible speed and power, went up to 180 ccs
you know it's a good mechanic if he has that red drawer with that stainless steel handle
This really takes me back to the 90's when i was in high school, loved it. One thing to keep in mind when doing this, is that the scooter will now require a lot more maintenance than the standard setup. Which can get annoying if you drive it daily and are counting on it to get you places. The fun factor of a geeked up scooter is incredible though
Why more maintenance? These are quality parts. I think he shouldn't have to regularly rebuild them.
@@EbonyPope stuff always breaks when you install parts like these. I knew several guys who broke quality crankshafts playing around like that. You're constantly having to adjust the carburator, replacing the clutch springs, replacing the clutch itself, the variator weights, valves break easily, etc. All that stuff wears, breaks and gets dirty at a faster rate. The number of work hours you'll put is ridiculous compared to a stock scooter
It's a good point, but these parts are fairly cheap compared to other motorcycles. Except for the time/labor.
Great build. I love the fact that you were openly nervous. Im nervous about most of the work i do on bikes.
Great work buddy.
It's amazing how old machines have more support than recent machines does as to upgrading and finding parts for em. I can feel the happiness from that initial start when it literally started like a brand new bike man!!! I know how that feels and pretty sure had one that didn't start most of the time except when it's cold LMAO. Used to have this 80's honda cub that I ride around with before it got stolen man, I even put a 125 mixed kit on it and everything and honda parts rarely change over time so it's easy to freakin mod. This one takes the cake though! Nice vid man :D
Upgrading a scooter to achieve huge power gains is a challenging yet immensely rewarding endeavor. The journey involves meticulous planning, technical expertise, and a passion for performance and innovation.
Your 50cc Honda scooter looks very similar to my first 50cc scooter, a Honda Vision, which I bought somewhere around 1995 in The Netherlands. I was 16 back then, the legal age one is allowed to ride 50cc scooters and mopeds, nowadays a valid license is obligatory. What about the US, do you need a special driving license for 50cc? What is the maximum allowed speed for 50cc two-wheelers? In The Netherlands it was only 45 km/h and every moped and scooter was throttled,. either with a special cap or ring in the variomatic (the front pulley) and/or exhaust. The easiest way to remove the restriction was replace the exhaust pipe and change the vario weights, sometimes also the fuel jet. Unrestricted a lot of 50cc 2-stroke scooters would easily do 60-80 km/h, with a racing reverse exhaust pipe sometimes even more. Downside was it being illegal. What do your local policemen say about it?
No top speed! WTF
Anytime I go with a new top end I definitely take the time to Port it since you already have it off and you gain at least 10 to 15% more power on top of the upgrade.
You should put fullvolume crank in that engine plus ct manifold to accomodate much larger size carb and gearings too. Believed me! It will fly!
That would be sick, maybe some day i'll do a full engine build on one
Great job J !!! But you have to break in your new , expensive top end. also dont wash everything dry. wash it just like you do the dishes. lots a hot soapy water. I use Dawn.
Yo broo!! i am so happy you finally upgrade this scooter good job!!!🔥
Thanks man! It’s better than I could have ever imagined
dont know a lot about you current exhaust but i can assure you if you get a yazuni R, yazuni c16, Yazuni c21 pipe you are gonna get it to go 50+ mph and even e bigger carb you can go even beyond that. Here in finland the moped scene is HUGE every single teenager gets their moped licence when they turn 15 so it is not that uncommon to see scooters going 60+ mph (the legal limit is 27)
Yep that’s awesome man! I am going to keep the stock carb for now for its simplicity and hopefully it helps keep the engine more reliable over time. Maybe some day I’ll do a build with a big carb
noo they to big for this Cylinder
@@rihardstomsons937 nah there not, i have a yasuni R under my DR70, great combo
For this cylinder yasuni c16 and c21 is a overkill
@@wieliszielyeah but a yasuni r is not even close to a c16 or c21
remember to break it in instead of giving it full throttle. We normally break it in to 155 miles.
yep, had to send it for the video haha so didn't have the proper break in im sure
@@TwoStrokeJ Oh okay! How is the Puch Maxi doing? Saw it sat without a cylinder, why is that?
To be able to just look at a CVT for the first time and basically figure it out on your own…fair play 👏👏. The starter thing is a Bendix, so well done Mr Bendix
I think you got a really good build for the money, but there are a few small details I noticed that you should keep in mind for next time. Since you bought a cast iron cylinder this time, it will take a very long time to break it in, and if you don’t do it properly, the cylinder might seize much faster. So, you should consider getting an aluminum cylinder next time. Also, when you upgrade from 50cc to 70cc, the moped's crankshaft may not be able to handle it, so you should replace it with a reinforced crankshaft.
If your goal is to do wheelies with it, you should also use lighter variator weights, as the lighter the weights, the better the acceleration. You should also replace the carburetor, because the stock carburetor often can’t provide enough fuel for a 70cc engine. And if you change the carburetor, you should ideally change the ignition as well, otherwise, it’s very easy for the moped to misfire.
Additionally, you need to get an unrestricted CDI, as the original CDI is designed to limit the speed to 25/45 km/h. But other than that, it was a really good build for $645
I’m a 31 year old, I’ve been riding since I was 15, I had a 50cc Honda scooter about 15 years ago and this brings me back and makes me want one! - old father with a GSXR and a few other bikes, now craving a scooter 😂
Me too 😂🤣😂

🦘🇦🇺🦘
I grew up on scooters. They are so much fun. $$$/smiles is unmatched.
you will need a bigger carb for more easy power.
15mm minimum for 70cc
but 18 or 20mm will be great, and then play with air / fule mixture and you'll get better acceleration and pull.
17 is stock on that honda bro.
be prepared to change the piston sooner since 70cc wears out faster and if you do alot of top speed pulls they wear out really fast, also a bigger carb will give you more power but this is as good as it needs to be
The malossi sport is a really durable cylinder
@@nico-broo im talking about piston they do wear out sooner and you will loose alot of power
@wash.625 My father did the same swap for his Suzuki 50cc when he was young (50cc were extremely popular in Spain), and he always says that eventually, the motor brakes due to the difference of pressure.
@@miguybaltasar1111I am from croatia and scooters are still popular here especially piaggio and people tune them in all kind of ways and I did them too, 70cc really opens the power but it wears out much quicker which isnt a big deal since the piston and cylinder malosi is really cheap to replace every now and then
@wash.625 especially when you don't run it in properly
CVT means continious varable transmission and its a Dutch invention by DAF who used it in small cars already in the sixties.
Bigger carb would do wonders on this bike ;D
Totally agree
You should buy a tomos 49cc 5 speed moped/motorbike they are really good looking bikes and are quite good at wheelies and stuff
Edit: they are also very customizeable from the bars to the 74cc kits and custom dellorto carbs, ive seen some that make 15hp at 74cc

Liked and subscribed from Hawaii we love our 2 stroke mopeds
one more thing you can do is get a bigger carb, it will allow the engine to breathe better and you should get even more power since the air doesn't get as much resistance as before

More Scooter Content!!! I love it!
Rings need to be letter side up and positioned with the gaps opposite of each other. If you install rings wrong it will smoke all the time and burn cylinder. And yes, always check gap by putting ring in cylinder, push down with piston to be sure it is in straight, then check gap with feeler gauge. Yama-Bond is the best. Grease the exhaust studs or they will be very hard to get out when you upgrade exhaust. Good job doing this on your own!! lots of little things people learn as they gain exp.
As we say in Germany: "Scooter tuning is not a Crime"
Usually when the part is so small like that clutch take it to the store so you check on the spot.
In the caribbean we use a flat screw driver and hammer to take off the 39mm
This is your best video yet
Got the same excitement watching this video as I did working on mine and making it fast. I also found that a racing CDI does wonders after swapping the cylinder. So does changing the carb. I went for 26mm nibbi carb. Keep in mind it drastically increases fuel consumption and your cylinder might heat up if you floor it for long.
It is really nice you had a personal shopper and mentor. I am out on the bleeding edge of stupid with a Jetson Bolt Pro. I got like, 5 useful YT vids and the rest I have to figure out. I am having a blast.
This is just beautiful man it just gave me hope for life
tip of the day:
Use a pipe wrench to loosen the the 39mm nut on the clutch, by hitting the back of the pipe wrench on the ground while holding the pulley and clutch.
Use this method when a socket isnt nearby.
When disassembling the cylinder head always remember to put a plastic bag or paper towel in the hole, ive dropped one of those c shaped pins into the engine once and almost debated taking apart the engine, luckily I had one of those telescoping magnets poles to use to get it out
This content is so underrated! Love this stuff man
thanks so much man!
Heating that carpet knife to cut the plastic was genious.
