My 15 year old son and I have recently purchased a 2006 Derbi Bullet. We're new to the scooter world and are learning as we go. We have purchased a few parts. A malossi multivar 2000 and a yasuni z pipe. I know we've probably started backwards but now we are wanting to go big bore. Malossi sport, polini sport, or stage 6 sport pro. What do you think would be our best option? I only suggest those because all are $250 can.
Very helpful!! Thank you.
Glad it was helpful!
Who do I contact to get a Exhaust for a 2005 Eton beamer 2 model PN2B. I was able to put on 02-11 zuma bbk but I want Exhaust and 15/42 gears. And Zuma exhaust doesn't fit. Any info is greatly appreciated.
This video will help so many minarelli ac riders
good
Who do you recommend to port and Polish RC boat motors? Do you have anybody who you recommend? Please comment back thank you very much
Running full polini setup. 70cc corsa with big valve, 21mm cp carb. Leovince gp2 handmade and polini highspeed vario.
Very nice!
Good video and very informative on what pipes and carbs run best on these different cylinders. What I would recommend though is showing the port lay out difference and exhaust port size on these kits. And also point out that the Stage 6 race has a bridged exhaust port which looks to me that can be opened even wider making even more power from this kit if fitted with the right exhaust and a large carb. I also noticed that the Airsal exhaust port was half closed. Meaning that it wouldn't make any power in the higher rpms over stock but would definitely have more torque due to the larger displacement and also may rev up a bit quicker over stock due to the nikasil having an effect of lessened friction on the piston rings. I had a steel liner put into my NSR125 (stupid mistake) and lost 5bhp on the dyno due to the friction on the rings. But it does come with benefits of rebore and honing as you mentioned!
What is the best for a 2000 kymco zx fast fever 50cc racing kit
thanks
Malossi vs polini Which of the two is more powerful ??
Could you do a comparison of the cylinders available for the 4-stroke Zuma 50F/C3/Vino Classic?
maybe
good vid bud
thanks
Hi I've got an fz50 what head can I put on that
Give this man a like! 3 years later still dead on lol!
thanks
Great video.
Why do you say you will eventually blow your stock crank with the stage six street race kit.
What pipe would you suggest to run with the stage 6 street race with stock carb?
Because Yamaha cranks are very weak. They fail. Street race won’t last very long with a pipe and a stock carb
With these stage6 cast iron cylinders, what spark plug do you recommend for colder weathers? B7 b8 or b9?thanks
call the shop and give us specifics
I have 2 zuma bws's one is an athena half breed. looking to upgrade bolth units to 70cc (whole pack) with the same setup, was thinking stage 6 but not allways available. Bolth run long and hot with weight ( mountian trips ) octane is about 100 - 140. Any suggestions on wich cylinder packs an carbs to upgrade with? And yes also doing the variaotrs, belt, gears.
need alot more info then that call the shop we can set you up with the proper parts!
I have the polini 19 mm phbg with fitted malossie intake but was wondering what line go where for fuel and air and oil go and I'm running it with a corsa and a v8 pipe does this sound like a decent set up. Just wondering what gears I should run
where did you buy the carb?
Love your videos and your shop. Going to be buying either a Corsa or Contessa for my '99 Jog/Minarelli from you guys soon. I don't mind a rebuild every 5k-10k miles or so, but anything more I'd like to avoid. I'm going to be uphrading the stock crank either way (suggestions?). Should I go with a Corsa or Contessa?
Get Dr.Evo 70cc i have that zylinder in my scooter and i works now for 23.000km , and you dont even have to change the crank
THANKS SO MUCH HAVE YOU SUBSCRIBED YET?
I love watching your videos, learning a lot.
I'm from Portugal and I recently owned a first generation Piaggio Typhoon, and started modifying it. I put a polini sport 70cc kit, a polini crankshaft, polini CP 17.5 carburettor (I increased the giglers) and a Yasuni r exhaust. I feel like it lacks a bit of power at high revs.
With your experience, I would like to know if this combination is good, or if I have to make any changes?
i would say its a carb isue i would put a bigger jet in it
mete um carburador maior 24mm é o ideal
Hey Brandon, would the air sal or a naraku kit work with a stock exhaust? Thank you, awesome vids
give the shop a call with more info
What are you thoughts on the Polini 50cc cylinder kits? They run about the same price as their 70cc cylinders. Was wondering if I was going to spend that money should I just skip the 50 and go straight to the 70.
100% go 70cc! let us know we can get you set up!
Thanks so much for making this video i had a aerox at 16yrs old now just bought myself a Yamaha BWS with full malossi kit on malossi clutch variator malossi belt light weight rollers desltro 19.5mm carb mallosi gear up kit, quick action throttle & it’s awesome it’s really fast Does anyone know if you can put a hydraulic brake on the rear?? It’s a 98 model. Thanks guys/gals
Glad I could help!
I’ve got a 1998 yamaha zuma with the vertical style cylinder set up, not the horizontal. Will these kits fit the vertical style too?
So on the vertical style Zuma, only the vertical style cylinders fit
I also have the vertical minnareli having a hard time finding a 70cc bbk carb and reed valve please help lol
I have a yamaha slider 2010 and i already have leovince tt black editon pipe and im thinking of getting polinis 70cc sport im just wondering is it worth getting a new pipe or can i still use the pipe i already have on? and btw my build is only for wheelieing and stunting.
only Leo vince thats worth anything is the one we just showed in a recent few videos i would not run one if you want speed
Jetting recommended for the 70cc street race, c16 pipe and polini 21cp? Thanks a bunch.
call the shop we can set you up
Will the Doppler crank you were selling be ok with the MKII kits?
Yep!
What kind of power and Pipe we talkin about on the polini sport kit I'm running a z right now with a 21mm dellorto the engine just ain't doing right how you know where the pipe turns on and off at
call the shop and talk to Paul he can set you up with something that pairs with your needs
your website does not have a selection for E-ton Beamer III, I know it's a 50cc, do you have any recommendation for the Beamer III 5BB VIN?
Correct. There is not a big demand for building them. You can send us an email and we can help you get started on a package
Malossi sport or polini sport are the best, great casting and last with a 17,5 mm carb. Had both, malossi has a bit more torque, polini a bit more speed. Its up to you but put a good crank in it, stock one isn't strong enough for 70cc. Good pipes are Gianelli Shot or Yasuni R. I rode both with a Leovince SP3, lots of torque and low sound. Only just a little slower on top speed as those other 2. If you ride daily I would recommend a Leovince Touring, Malossi multivar with 5,2g rollers, malossi ventilvar and yellow malossi spring
ok
Stock crank is strong enought for a sport cast
i love info,ggz
thanks did you subscribe?
One of those 17hp kit would be amazing in a big 16" wheel kymco people or piaggio. Are there any 2T 16" scooters floating around left on the market in the US? Also been a fan with the 14 and 16" wheels, handles more like a bicycle, motorcycle, doesn't want to stand up or torque steer when braking in corners like the 12" and 13" do.
no 2t bicycles here
@@Scooterswapshop ah in that case the liberty 50 4T with 80cc molassi bbk and ecu would be about as good as it gets stateside for small big wheel scooters that qualify for 49cc Uber Eats registration.
Hey, what about water cooled cylinder ? Can I also have a mechanical water pump on zuma
call the shop talk to Paul he can set you up with what you need if you haven't already.
Hey guys, Thanks for this great video. I have a 2005 Piaggio Typhoon that has 12k mles on it and has been sitting for a while. I bought it at an auction and it had the stock pipe on it when I got it that was rusted off at the head connection. I only just managed to get it running and rode it around the yard then parked it for several years ago. I want to buy one of these kits that is the the most reliable, I won't be street racing but I would like it to be fast and I would actually like it to be very quiet if possible (sleeper?). I would much prefer to have strong mid range instead of extra top end also. What would you suggest for a kit, carb and pipe and how much can you sell it all to me for. i'm in N.C. Thanks in advance. I will also check out your posted sites
I recommend buying from scooterswapshop or Racingplanetusa. malossi 70cc kit is pretty reliable with a 19mm or 21mm carb to take advantage of all its power. exhaust im not so sure about because the stock one will probably not be the best to use. Tecnigas does make a silent pro exhaust but i have never used it.
@@lek2455 Thanks, I appreciate that. I'm looking for a quiet probably Leo Vance so I can go off road it in the woods near my house with less neighbor complaints everywhere, also
Don Favro if you put a leo vince it probably will be almost rhe same noise as any other performance pipe. i also heard leo vince isnt that big of an improvement over stock. not sure, my scooters ive owned i always went with tecnigas exhausts. currently own a 2011 Eton beamer 3 with a technigas next r, ncy clutch pulley, and also waiting for malossi 70cc kit and 21mm dellorto carb (shipping is taking forever).
looks like you got helped
i have a question can a Cylinder kit Malossi SPORT 70cc 10mm Minarelli Vertical fit on a Hyosung plz let me know
zero clue on that one bud
I'm talking bout the Chinese motor kits that are bolted on to bicycles.
There 70/80 cc. The one I just purchased is a the newer version suposedly100cc.
There all I believe based of the original block 49cc.
Some called PK80
a crack head bike?
Hi man, i have a stsge6 street race 70cc cylinder kit, performance exhaust, stock mikuni carb, 5gram sliders, stage6 variator, naraku drive face. Question is, do i need to warm up the scooter from cold start like for 2-3 mins? I just notice that if i run it straight away from cold it boggs briefly then it goes away and will be fine. Do these cylinder need warm up?
Nino Echavez u shouldn’t ride a bike without warming it up first
Yes absolutely, warm it up or you can 4 corner seize / stick a piston
everything has to warm up bud....
There's posts of motors having chainsaw jugs altered with spacers and that being about timing n port issues
ok
what cylinder kit do you think is the upper limit on a stage6 pro replica exhaust.
call with more info
Going to get s6 MK2.
S
hould work with carb dellort 17.5 and yasuni c16 or z?
Z is a stock replacement pipe and the 17.5 is far too small
How many gas tanks must one fill up to break in a 90cc cylinder on 2t’s ?
5 heat cycles it should be ready to rip
i want to build a low rpm torque monster on a peugeot witch Exhaust do you recomend with the 70 cc cast iron
what type of engine is it
@@Scooterswapshop It is an Vertical AC peugeot vivacity from 2006
if i plan on putting a bunch of miles on my 2008 zuma what is the most reliable bore kit? Palini Corsa? or Contesa? or other?
Kamron Polini and malossi are both excellent options!
Scooterswapshop thank you so much! So a real quick question, I live here in Portland so I’d be coming to you guys for work and upgrades, so I deliver for postmaster and Uber eats, I’m picking up a zuma 50cc 2008 tomorrow. Both delivery companies require a 50cc no faster, in your opinion how does the 50cc do going up Portland hills west of southwest Portland? I saw on the internet, people saying that the 125’s engine will last a lot longer plus with the ability to be able ride across state etc. why I ask is because I also have an offer to grab a zuma 125 09 for a very similar price less the 3000 miles on both. What should I do? Any advice?
I figured I’d just keep it hush on the cc increase☺️
Haha awesome! Come by sometime I can give you more options
With all these cylinders… how would you rate/compare the Motoforce 70cc kit?
Moto force is at the bottom just a little better than Amazon eBay etc
Really handy information was given out as I heard quite a few ideas and knowledge that I already had being confirmed in the video 🙂.Would still like to ask you guys why wasn't an MXS cylinder and an Athena cylinder included in the bunch? My interess and curiosity in these brands has been growing as I'm trying to gather as much info as possible in order to make my choice on a new 80cc cylinder kit (∅47,6)...
There is no Mxs for horizontal. And we don’t deal Athena
@@Scooterswapshop Ok,that's understandable if you say you don't deal Athena products.About the cylinders,you mean all the cylinders you presented are for horizontal Minarelli blocks? I thought there were cylinders for both horizontal and vertical Minarelli among the ones you presented. My scooter's block is a vertical Minarelli so judging by your answer there are indeed MXS cylinders on sale for Minarelli vertical blocks like I previously thought there were, right?
Thanks for the info! I am probably gonna roll with the Airsal, I have a NCY pipe, and want to keep the stock carb I am a commuter.
Did u keep the stock cam?? Im thinking of puting a airsal 70cc on my 1991 zip
@@sleepy5504 I just saw the reply, I am planning to keep it as stock as possible.
give us a update!
A yasuni R won’t work great with a Streetrace ?
No sir
We're would you rate Athena I see them for $130 plus shipping?
call the shop
Very good info, isn't the air cooled MHR more powerful than the stage6 race bore.
The stage6 race and mhr are very similar in power. However the mhr is a higher quality
Bore
@@Scooterswapshop ok i would've thought that the mhr would've been more powerful. My fav air cooled 70cc cylinder is the polini evo. Those are straight beast. I've seen those smoke mhr air cooled cylinders. Too bad polini stopped making them.
wsmaga yea we’ve dynoed them all. The mhr and the race are in the 15-17 whp range. Pretty close in numbers. The fastest 70 is the 2fast by far but it’s a lot of machine work and porting to make work right
Do you have an opinion on the motoforce cylinder kits? I have an Aprillia sr50 ditech that has less then 700 miles and previous owner ran it out of injection oil.
They’re as cheap as they get I would strongly advise against using one
@@Scooterswapshop I appreciate the response. The cylinder is cast iron so it could be bored if oversize pistons are available. Tempted to go 70cc kit but these ditech seem overly complicated and I’m afraid to create a nightmare. Do you have any Aprillia experience?
@@jimccc9467 yea lots of experience with these! Check out our newer videos
@@jimccc9467 at the end of the day you get what you pay for. If you buy a $125 cylinder kit expect issues. Buy the malossi kit and you’ll have no problems
@@Scooterswapshop I see Malossi 70cc kits, some come with another ecu and some come with another cdi, which is appropriate for the 09 Piaggio? Do you folks sell the kits? Do you have a pipe preference that is appropriate for the 70 kit?
i hope yasuni r gonna fit for my setup i got polini cyiilider annd 17.5
did you have a question on it? when did you purchase it from us?
Will any of them fit a Chinese bicycle motor kit ?
bicycles don't have engines
Polini Corsa ported, polini race 4 crank, polini cp 21mm carb with polini pod filter and stage 6 pro replica on 2005 Zuma
sean snyder I want all of that for my 05 zuma but with the c16 exhaust should that be fine?
@@fernandosegobia7089 yeah that would be perfect I spent close to $1k on everything
sean snyder same here I’m just waiting for everything to be in stock like cables and stuff trying to buy everything at once
cool
I cant find the malossi kit
can you link it?
what bike what kit?
hello, im from amsterdam alot of these brand's are really common to know about for me like airsal,polini,malossi,athena....how familiar are you in america with the 2 stroke brands?,, my opinion about the cylinders it's a great layout i in person will only use air cooled iron cast polini stage 6 dr,top performance cylinder kits simply because those alu race kits air cooled get to hot with road use, all these minarelli AC engine's u can easy swap to a LC build and make those cylinder kit's last 3 times longer and keep the ideal temperature range and keep the peak power and not burning the piston rings i heard u mention yasuni exhaust those are definitly top of the line :D having an r,c16 u can drive almost any kit already :)

Best kits you have for Af18 dio etc ¿
we have a video on this
@Scooterswapshop I've been waiting since 2019 and all I care about is the alfio kit.
Will any of these last a long time and be reliable?
all depends on your set up and if you know how to tune and maintain.
So what’s the exact difference in the corsa and the Cortesa?
Corsa is factory Polished ex port chrome ring comes with reeds and spark plug and also has higher compression
what size Carb is best for the streetrace ?
19/21
Scooterswapshop thank you
Just another question sorry but with the streetrace plus a 21mm carb is the voca sabotage exhaust a good choice ?
When will the 70cc bbk polini corsa be in stock
This week
How do you tune the stage 6
same way you tune any kit time and skill?
@@Scooterswapshop jeah thx for the tip might have been usefull 3 years ago😂👍
What about 139qmb gy6
Whats best polini evo 70ccm ac or malossi mhr ac
That’s a tough one. Both are really good. I’d say polini over malossi for street and broader power malossi for more peak
Scooterswapshop its just bc i have asked many ppl and there say malossi bc it can go more fast and make me hk
The Stage6 street tunes down for the low end really well. It can make power up into 12k RPM, but it also can get mountains of torque lower down in 7k/8k too. Which is what makes both usable and unusable with the stock crank. You aren't going to be using it with a stock final drive and and high RPM pipe on stock. Using it with stock/silence design pipes, and pipes like the LeoVinceTT, giannelli extra, and the china special, along with heavy weights and a long final drive- will work really well on the stock crank with it.
The stage6 replica pro, is designed to go with the cylinder, and really breathes the large powerband of it (is insane, makes power between 8k and 11k), can also be geared and weighted heavy for on the stock crank. The cylinder WANTS to rev high, but will still be content running in the lower end of things.
ok
Yeah I have a stage 6 70cc makes grazy power
What size is a stock carb for a af16???
Swimming Free 12mm
Maybe 15
depends on the setup
I run the malossi with an 19mm carb, an I love it,
Did you have to change the crank or will the stock 1 suffice?
@@graffiti4416 Stock crank will run perfectly fine. i also would recommend buying a 19mm or a 21mm carb with the malossi 70cc kit. stock carb with upjet will work but theres alot of power you would be missing out on.
nice!
Any idea bcr?is good
bar?
Hey juch need to no something about 100cc and Big bore kit thanks
Ok
@@Scooterswapshop Just wondering if you would be able to tell me if i would need to modify my engine case to put 124cc malossi kit on a yamaha neo's yn 100cc 2 stroke model year 2000 or what would be the best Suggestied big bore kit for this model
As I don’t no !!
I’ve run the street/race and the corsa both on a Gianelli reverse pipe and 19mm dellorto carb.
The street/race felt better on the butt dyno.
I’ve ruined two kits with rod bearing failures. Both basically my own fault. Buy the highest quality rod bearing you can. Definitely not a place to skimp. I’m currently running a bearing for a KX65 12mm pin.
