Scooter Cylinder comparison POLINI vs CHINESE KIT
Вставка
- Опубліковано 22 гру 2019
- Scooter big bore kit comparison. Yamaha zuma, honda elite, its all the same theory. Here we're unboxing, and comparison of a couple pretty commonly purchased cylinders. I don't go over the hp differences, but rather what each of the kits entail, what you get and the major differences. Not everyone needs or wants a high end kit, but its nice to see them side by side, as we explain the differences. There is NOTHING wrong with running a budget kit, if your looking for a budget build, jsut dont expect a $90 kit to perform as long as, and as well as a $200 kit. Let us know if you need help getting a solid solution for your bike. Ready to help as always, scooterswapshop, with more 2 stroke parts and knowledge, than any other usa store :)

Could watch these videos for hours.. so when I get bored with my setup we can throw a 2fast on 😂 solid video as always merry Christmas to the SSS crew
thanks skylar! I need to get back on my 200 build
The most popular two-stroke bike in Taiwan so far is Honda Dio, which has been in vogue for more than 20 years. So Taiwan ’s modification technology for Honda Dio is very mature. I also have a Honda Dio with a piston diameter of 58.5 mm
Taiwan is not China junk.
Bert439 of course not😁
Whats a honda dio? jk
@@Scooterswapshop ？
If you want a reliable fun and cheap cilinder, get yourself a DR70 kit, I have one on my LC Piaggio. It isn't extremely fast, but it is incredibly reliable and accelerates like a stabbed rat.
cool
How much bhp can you get from a polini 70cc corsa?if you do the complete engine?
This is why i only buy from sss. literally have helped me through so many questions and always point me in the right direction.
Thanks buddy :)
I second that comment
Do I have to put in the extra supported crankshaft to put this on a Yamaha bws?
not sure exactly what your refrencing send a message to our app or give us a call we will get you taken care of!
Is the NCY 50mm cylinder for Dio ok for a budget cylinder?
Sure
Hey I bought a polini 70 for my roughhouse50. What carb do u recommend? My last builds were my Honda Dio’s 72cc with Oko 28mm carb.
Hi If you need a package on carb etc just hop onto the website and grab the build invoice we can get all your details budget and needs.
There’s a special kit for the genuine as the only intake available is way too big
Do you guys sell anything for a 49cc taotaowith a 52mm big bore kit upgrade? I'm looking for a good exhaust......Thank you if you respond...
Sorry, no
For the most i can recommend Diffusione Ricambi (Top Perfomances) Not too expensive and its reliable bang for your buck.Just leave out the headgasket and Lift the foot a bit.
Why no head gasket?
......
Top Performaces is the best for minarelli, great products for money... :)
Wat size up jet would I use with ur prefmonce exhaust on my aprilia area 51
Impossible to say unfortunately
I have a question for you I Bought a complete minaralli hybrid bicycle engine I noticed one of the cheaper Chinese pistons is in the minaralli I purchased here is my question sir I live in Texas I have about 170 miles on this motor she runs hot here in Texas I think it's cause she is still breaking in the co. I purchased it from says if I put in a better quality piston it would run cooler now this is the cast iron version or would I be better off using a athina aluminum cylinder or can you please point me in the right direction the temperature the motor is getting up to 340 and I shut it down that's after a few mile ride and I exchange the cast aluminum head for a cnc high compression head better cooling or will it get better just keep babying it
hybrid bicycle engine Yeah not gonna be able to help on that
I got a Honda ZX and I wanna upgrade the cylinder head to 70cc, how could I order parts from your store.
go to our store online
Airsal is also a very good budget kit it always has brand stamps and very good casting but it doesnt make as much power as polini or mallossi kits.
sure
Would one of those 2 fast jugs fit my bbr 66/80 ?
call the shop and we need way more info
Can I put a pre bug front pannel on a 04 bug eye zuma
No
Naraku fits in where ? I'm want to keep the stock crank and carb with an upjet.
Bert439 naraku is going to be similar to the Chinese cylinder.
Thanks for the reply Taiwan made or like you said a re-branded China cylinder? I'm running am NCY Pipe and transmission kit. I'm a commuter.
The red wrist pin clip plastic bag looks identical to the ones I got with a cheap jug for a 50 cc stihl chainsaw.
cool
Yo dude im from germany i found youre video. Please show ur high end scooter. I want to see what you got over there.
Lakumar OG hey buddy! Just look at the other videos we have a runner and a couple twin cylinder builds :)
Merry Christmas
thanks
Do you have a used leg protector/dash for a 04 zuma if so how much
we don't offer used products
@@Scooterswapshop wow that was a year ago but thanks
How about TWH kit? Is it good for the price?
Twh is the lowest quality bore made. They cost $7-10 wholesale
Glixal makes a decent product if you want to go the cheap route I have a bike build with a linhai scooter that I put all glixal parts in 100cc bore kit with cam and all kinds of parts it will do around 45-50 pretty smooth
no cheap parts
Do you have part for suzuki address or ag100
no Suzuki
How are the gy6 taida kits?
Terrible. Taida went all China.
@@Scooterswapshop good to know almost wasted a lot of money.
How much block ang pistonket for vento gt5?
call the shop
How much for those blue rims n fit 50cc
call the shop
Is there’s any 50cc watercooled cylinder for dio sr?
Sr?
Scooterswapshop honda dio sir
👍👍👍👍👍👍
thanks!
4:59 what tittle of this song?
couldn't tell you lol
Yo this video old but I have a 1987 Yamaha jog with the vertical sh50 engine this kit would work with me
Sorry there’s no kits available for the razz
Do you have a kit for a 139qmb?
we can get them if they arent in stock check our website
@4:55 sounds like that Saint Pepsi song
ok
Good Morning, I have a 2018 Falcon 250cc Motorcycle/Scooter/Moped Chinese made. I’m in need of a piston or rings and cylinder gasket but I HAVE NO IDEA where to buy any of these. Can ANYONE HELP PLS??????!!!!!!!!!
I have 50psi Compression on this bike. It sounds like it wants to start but doesn’t.Thanks
Unfortunately there is no part numbers for your bike so there’s no way to tell what you need.
I want a cylinder for honda dio af-18, 56mm
they are super common and everywhere just look it up
listed on our site
You do great videos they are very helpful!
Could you maybe help me with build that I would like to do for my 50cc 1997 Yamaha SPY(CW50RSP). I would like to tune it to 80cc-100cc. Could you DM me? :)
How can I help you?
the Chinese one is 50cc, you can see from the dimension of the "camicie", the metal part that goes in the carter
ok
Bought expensive polini sport 70cc vertical cyl and it didnt last...bought some random cheapest 70cc cyl and it's still working great and doesnt overheat like polini was...disappointed in polini
Sounds like your tuning was off. Never would we see better life out of a cheap china cylinder vs a Polini.
By the way, the kit is not Chinese... it's from Poland I saw the certificate.. they sell these cheap kits in Europe too. In Europe they go as cheap as 30 euros (35 bucks) for a Minarelli vertical engine
nope its china
@@Scooterswapshop I won't argue here, we have a lot more of these engines in Europe and I saw polish writing on the box, maybe you bought it from a Chinese seller but they're usually made in Poland because it's a lot cheaper to ship it to other European countries.
@@greatestevar This dude you're talking about is American and he probably barely knows anything that we have or know in Europe, I'm ending this argument.
I bought a $100 jug and piston, head for 4stroke, the head was so bad, I wouldn't use it, the valve guides were so deep and big. It blocked 80% of the port! On both sides, how do they expect that to work! I bought another stock head and ported it! The guides are all close to blocking the ports, I can't allow myself to install the head without porting it! And the piston looked like it was the last of a 1million run, and casting was very rough on the dome, I polished it best I could, and unshrouded the valves, it cost some compression, I need to delete the base gasket, or get the head or jug cut about .030", and fly cut the piston about .015" depending on clearance, I'm building a 52mm bore, 95cc 139qmb, hoping for 15hp+ with a bit of boost!, I'm hoping to eventually get a 2stroke scoot!
15 HP ON A QMB? NEVER HEARD OF SUCH A THING
@@Scooterswapshop with boost!
Malossi❤️
I'm adding a Malossi Varistor and sliders along with a new clutch and bell.New beltm
yuupppppp!
Taida is not Chinese, it is a Taiwanese brand. This brand of cylinders is also a relatively low-end cylinder in Taiwan.
胡迪 they are based in Taiwan yes. Most their cylinders are bottom shelf China. I bought from them for several years. It’s terrible
Scooterswapshop 😅
great video tho i got to say i fited a $40 chinese 70cc kit that come with a head to my minarelli horizontal 1E40QMB has done so well and yes it dont have the power of a polini kit or as high reving but i only fitted it as a budget kit to i have build my stroker engine but 7km done and still going :D
Yea I’ve ran them too. They fit the bill for the price. Just Low power and short life expectancy. But for that price you can’t really lose
@@Scooterswapshop oh 100% with you but if your just using the stock pipe a cheap 70 kit will be fine as will give a nice bit of boost over the stock 50cc and i cant belive this kit has lasted so long as im running premix using some junk outboard 2 stroke oil but now it only has to last one more week then my new kit and crank will be here i hope as i have to inport them as no one in the uk sells stroker cranks for the minarelli horizontal
@@mrchilled85 Hows ya new kit compared to ya old one?
@@AaroMesa my new kit is not here yet due to Christmas holiday :(
These cheap Kits like DR Evolution or something are Great for porting, because if you mess it up its easy to replace XD
Dr is cheap, but still a quality cylinder
Dr is Top performance, the difference between Dr and Top is the finishing of cylinder.
ok
For cheap kits.. have people here tried 200 or 160 cc.. taiwan or thai made? Like 150usd.. or sumtn
👍👌
thanks
Only polini for me.. Have a 102ccm Kit on My piaggio ape 50 🤘
nice you get it from us?
Wow
wowsers
U never talk about gear kits like molissi straight cut gears please do a video
I can plan it. But gears are gears really. One brand vs another do the exact same thing. As long as the ratio is the same they perform identical. Minus the annoyingly loud stage6 gears
@@Scooterswapshop Thanks 4 the reply I noticed u dont piaggio nrg or gilera runner parts any reason y thanks again 4 the reply love this page
Pat Sherlock hey pat! We didn’t get any runners or nrg here in USA unfortunately
Malossi & Top performance & Stage6 . Are quality cilinders pricing range from 80 - 500 Euros
correct
@@Scooterswapshop Thanks, i have bought the Top Performance Due Plus
You need a new camera nice video make more but with new camera more quality footage
I just need to use my gimbal. It’s a $1000 camera. Just taking the time to use the gimbal and set it up right. This was a quick video before I left on vacation :)
You didn't show us any of transfer ports or anything. Just the outside of the cylinder. Who cares about the outside its whats in that makes it run. Maybe do a comparison of port timing and duration w/degree wheel next time? Or have your mechanic do it for us please. Thanks for the little bit of information otherwise.
can't please everyone and can't give away all the secrets ;-) We do what we can to get info out there.
You're talking out your ass about the gaskets, Yamaha uses that style of head gaskets from the factory without any additional goop and they work great for hundreds of miles. If you torque the head up properly it should seat nicely and the copper will deform to seal the gap.
We build bikes for a living. Remember we’re not dealing with FACTORY Yamaha japan products we’re dealing with CHINA. We’re also dealing with 130-170psi compression, not the factory 115-125..If you think that a flat stamped metal gasket is better than on o ring you need to brush up on your bill nye lessons. Companies do this to save money. Period. Also these flat gaskets are aluminum typically.. not copper
@@Scooterswapshop Of course it's not applicable to tuning cylinders but it works fine. Same with that POS chinese cylinder you show in the video, that's basically a stock replacement.
Athena uses this same design. Cheap stamped metal. So does taida and twh on bores that see 165+ comp. some of these cylinders are 130cc with stamped metal gaskets. Air cooled, paired with high comp, large cc, with a thin stamped metal gasket good luck.
13:25 Oh NOOO!! not a Champ Spark plug..no..Ngk please.
NGK ONLY
polini is the best 22 years ago was beating every scooter back home ,whit mi polini kit !!!!!!!!!!!!!!
cool
For standaard scooters b brands are fine no problems with cilinders. Only imitation carburateurs are not so good they escape air😐
chinese brands are junk sorry
What about us GY6 4 stroke 50cc guys? Seems like a lot of Chinese trash big bore kits, what's going to make power?
All the china bikes are gonna have garbage kits
Ingin Name Plasse
what?
Yamaha jog with an eBay $45 48mm kit = wheelies
you can wheelie with any cylinder. Stock all the way to 35hp. :) Run whatever works for best for your application! Wheelies are a good thing.
Power wheelies
malossi or dr racing da best tho :I
2 fast is the most hp, malossi and polini are best for longevity and work really good for most people street riding. Dr is a great product also
I don't know why you say the athena kit is not well made/cut corners in manufacturing just because it came with generic gaskets and whatnot. I have an athena kit for the prebug and comparing it to the corsa it is just as good and if not, better. Packaging is similar to the corsa as well and the gasket package is not the same as the generic chinese cylinders.
I said Athena cuts corners on the gaskets. Taiwan style gaskets vs Cnc head and o ring. Its a fact they are more prone to leaking. I said nothing about poor packaging etc. I mentioned overpaying for a inferior design. They’re the only company that charges what they do and give you a stamped metal gasket. I never said it was bad kit. But if your going to spend nearly $200, you should be getting a Cnc head with o ring. As the $140 malossi even comes that way. I’ve met with the Athena Italy rep. His exact words were “our main business is automotive parts we don’t really care about scooters”. Vs polini who is racing and competing every year. Athena isn’t. A bad kit. Just overpriced for what you get
Also athena kits are not styrofoam, they're cardboard, the packaging is almost identical to the chinese/taiwan kits.
ITS HP FLAT# X RPM# = MAX HP
ummm ok. cool
Umm a dr 70cc are €100,- and they are great they can go for 20k kilometers and they almost never get over headed en have great power but stil i drive a 70cc malossi zip sp
cool
Hyundai have been build better cars than Toyota for years, less recalls and warranty claims......you might want to research things before you trash talk them on youtube.
Some of the motors are really stout. I’ve owned several of these vehicles, I speak from my own experience. Thanks however.

?
here you have 70cc whole new chinese kit for 25$
Yeah never want that lol
looks like a 50cc cylinder not a 70cc
It is. But the 70 is identical just bigger piston and bore. Just showing the differences in quality and what they come with etc
Look at the exhaust port, definitely a 50cc kit.
Bert439 yes I mentioned this several times in the video. And believe it or not a lot of 70cc kits have small ex ports like this. Airsal is one of them.
Thought you was going to compare the speed not what is in the box crap
To put each cyl on and compare max speed would take about a week with tuning
Un número de teléfono que tenga por favor 🙂
our number is on our website
you know when hes full of bs when ktm uses athena cilinders on there champions dirtbikes :P
There’s different grades and designs for different bikes. Like dewalt. The consumer stuff at Home Depot is junk compared to the ones you buy at platt etc. I’ve also owned 5 different ktms. And I’m very familiar with all their downfalls. That’s why they didn’t use the adv ktm’s in the long way around too unreliable.
@@Scooterswapshop yeah oke i can understand that but athena is not junk mate :) for the rest i realy like your channel pls post more :P also more of the ride outs thats so cool
Cmon guys.... we Italian excell on handcraft. Please don’t compare us with Chinese stuff 😂 Italian rules on cars and motorbikes 👍
I agree! Your be suprised how many people think it’s all the same quality.
I hate that it's so hard to preach quality to people on the parts that matter. All variables equal a Polini kit will start easier, be easier to tune, make more power and last 100 times longer than a China kit. I've seen Chinese kits with a .015 piston/wall clearance, tapered cylinders, out of round cylinders, out of round pistons. I will gladly spend the extra $100 to not have to do the job again in 1000 miles.
Monroe White my thoughts exactly. You can get “ok” performance and have the china kit last a summer; or spend $100 more and get far better performance and have it last years.
Separates bad ass stuff from junk. I love quality products. I know a guy who said his bike wasn’t doing wheelies at sea level. I told him what parts I had and he said he had basically the same parts. I beg to differ. I am at 6000 feet above sea level riding wheelies. We don’t have the same parts.
stay away from the std pistons
cool
😂 US People and Diskus over Qualität 😂
Wenn man das ließt kriegt man ja kopfschmerzen
sure
polini aint great performance :) go good or go home xd
It’s beyond me how some people can cheap out on a build with China stuff.
welcome to 90% of people
Lol cylinder says std no wonder it's cheap and gets sent to every company to use it lol 😆
?
