You guys make a great instructional video, it was just a pleasure to watch! ☺ I'm 66 and still fiddling about with scooters and other two strokes, mainly veterans. But my son has a Zip that got scored, so he's putting on the same Malossi sport cylinder. Already had the same exhaust, Leo Vince. So he was over the hill when I sent him a link to this video.. A very professional video production, and you blokes are entertaining. Thanks !
NO WAY! I never been so proud to be italian like today hahah. Well done guys, it's so satisfing that Zip is loved till Down Under. I'm now subscribed :)
I've been pretty experienced tuning small 2 strokes with manual gearboxes. And I got myself my first ever scooter a couple months ago and it's been really hard for me to tune my rollers, clutch bla bla. This video is definetly very informative about how this stuff works. I am confident that I again can take upon the challange and get this thing running like it should.
Guys, massively appreciate the video. It was so comprehensive and I came out with a whole lot more knowledge. Thank you so much and I wish you all the best.
Thats the most cleanest zip 2t i have probely ever seen in my life . All the other ones got damage or are customized. That exhaust is pretty good though. Would not have expected that.
Reminds me of the old days. One day i walked up to the nearest motorshop i always got my stuff. Walked up to that guy and asked him that i was looking for a Polini EVO 70CC for Piaggio. Back then the kit to have (15+ years ago or so). I saw his eyes grow and the next thing he said to me "What the Heck do you need that Kit for??" i imediatly realised i was not going to get that Kit at that time. His reaction on my question was priceless, something i have never forgotten. :) At some point i ended up having the desired kit and it was great fun. Just dont get caught when you run it in the streets.
Good story Johan, 15 years ago only Scooter tuners would have known of these parts😜. The first time someone asked me if I had any Polini stuff I pointed towards the fruitshop down the road.😂
The inlet plate in the carburettors mouth (brass plate) is not a restrictor, it’s actually serving its purpose delivering air flow into the right areas of the carb through the air holes. Often people believe it’s restricting the flow of air, but after performance parts get the jetting right with this little plate still in you will be onto a winner👍🏻 try with and without you’ll notice the sharper response and reliability from keeping the plate as is
i have been struggling with my vespa sprint for a while i normally only work on classic scooters but now thanks to you guys i found a couple of my bikes problems and got some really good tips. thank you so much!
This is the best most clea,r concise instructional video i have seen on my bike. Its told me everything i needed to know in less than an hour. Thanks guys.
Just to be fair, I have enjoyed thoroughly the video and brought fond memories back :) Just to point out when you talk about "this isn't ideal to go super fast" perhaps you ought to know that there is a quite active racing scene where these little buggers go up to 160 Km/H
@@scooterstreetau Absolutely correct, the SP is the water cooled one, but to the best of my knowledge it should be possible to convert any version to liquid cooling: the only hiccup would be with the clearances in the leg shield trim, as there's a storage compartment that would interfere with the radiator's positioning. For the sake of honesty though, I'm not going to vouch about the accuracy of the info, it's something I recall from when the SPs where just hitting the market in Italy some 10+ years ago
@@LucaFiltroMan We have done this conversion. We took an air cooled Zip and fitted the Radiator with electric water pump, cooling hoses and the water cooled racing cylinder along with many other tuning parts. We also changed the front panel and fitted a genuine SP front cover so the incoming air could meet the radiator. The performance was as you described, Ridiculous power!! This was an expensive project... We lalso did the Superman theme custom paint job and it did fly🤣🤣.
You probably noticed apart from the water cooling system on the SR50R, the base of the 2 engines are the same. You will notice between the Piaggio/Aprilia 2T models they look the same but each model has a different transmission length to accommodate the rear wheel, this includes each model running a different belt size to connect variator to the rear pulley.
I believe 2019 SR50R has the new Euro 4 emissions system also, which uses a different carburettor, stator, coil and CDI/ECU. It also has the larger temp sensor on the head, and the solenoid air valve for the electronic control of the carb.
Wow had a severe case of nostalgia kicking in watching this, i’m from belgium and almost 38 but was doing the exact same thing since i got my first mobilette called the honda camino at the age of 16 , ended up going to school learning all of it and not just placing parts etc, now after 2 strokes i suffered at 34 wich paralized my left side so its kind of hard to watch without feeling the pain of damn the days where i was ok but it feels great!, you got yourselves a huge fan!, in my days it was either the dick ring or just dick for the exhaust🤣 how are the laws on tuning scooters in australia? We had cops stopping you randomly where they were standing near a random road with a portable speedometer to check 😫 they confiscated it to give you permition like a month or god knows how long to pick it back but with all the illegal parts removed for you by their own pissed off mechanic if you catch the drift lemme go check your ig out peace!
Gday mate and welcome, Great comment thank you! See you're never alone😁😂.In Aus we do not have these rules, the country only adopted emissions rules 12 months ago.🦘 Wow and the Cops remove the parts? Hard core.. Over here no such thing, only speed and Hooning laws. All the best🛵🛵
Great videoes and work ive been races kx 500s quadzillas and turbo street/street bikes for 30 yrs now and im loving these little 2 stroke rippers and builds i may sell two of my big bore bikes and get 5 more of these 2 strokes i just picked up a yamaha qt 50 and a yamaha riva lol
Thanks brother! Im almost there! I got my sip running lile a beauty with this video and i have never touched a tool before. I cimmented before and you answered. Im lamost there brother!! Messing around with weights i have 6.5g at the moment. Think i will try 6g and contemplaining to put the malossi fly clutch with bell on.
Great stuff, very happy for you😆. Note: The lighter rollers will allow the engien to rev easier but go too light and you will loose pulling power through the mid range. Fitting a clutch or fitting tighter clutch springs will make a positive difference to the rpm build and the initial acceleration.
@@scooterstreetau im so happy for your existence and that you made this video 💯❤️ you helped a man on the other side of the world literally 🙏🙏🙏 Ill put in the clutch tomorrow and i will order some new clutch springs and some contrast spring? I thinks its called 👍 anyway big big big love 💯❤️ If you were in Sweden i would fuggin hug the shit out of you brother ❤️❤️ keep doing this kinds of video and i would love to see some more build from you guys 🤔 sorry for long comment but you really saved me, my man 💯💯💯🙏🙏🙏🙏😇😇😇

Only thing is that im lefthanded and assume the guy in the video is right handed bcuz of sometime when he said do from this side cuz easier angle, sometime is opposite if you are left and its possible from the other side, just a side note 😅🙏 Thank my brother from AU 💯❤️
Your issue is very common, you have not made all the required changes to the engine. Go back to the start, remove all the parts and fit only the Variator first and then test ride. If all is OK then move to the next step. When we fit an exhaust you should watch one of earlier videos to see what other parts MUST be changed to get satisfactory result. Also watch the clutch springs set fitting video. This video will help for the exhaust part of your project. th-cam.com/video/kFr0nwXf448/w-d-xo.html&ab_channel=ScooterStreet
@@scooterstreetau no problem at all. I just got a zip and have purchased a few products from you. I hope I got the right ones. Just going to do the rollers, jets, clutch springs. Got a Leo Vince off a friend too. Was going to hold off on the 70cc kit for now to save some money. Hopefully it all goes well.
the "emission controller" is actually there to provide a certain amount of oxygen in the catalysator that is in every single stock pipe in european bikes, and theres a check valve so that the exhaust gasses dont go into the variator case or where ever the pipe takes the air from
There are two types Dellorto PHVA 17,5 models. A modified "low emission" type named "OD" with a fat needle, smaller cut away and different needle jet (emulsion tube) The other one is the "normal" one named "TS. Thats the one to go with. Much more easy to tune in, especially in the middle range.
Thanks EnergyXyx, this is great information🙌. There are more than 11 PHVA in 17.5mm range. Parts change between them such as the slides, needles, atomisers, jets and so on. Heaps of info on Dellorto Uk website for anyone needing.
@@scooterstreetau yes there are so many models, but just stay away from the bad Euro4 - OD models. The good ones often comes with A20 needle and a 40 degree cutaway throttle slide.
That small intake pipe for air come true I would not takeout from air filter otherwise I difficult adjust airflow and the carburetor hasn't worked properly.
putting this this kit on my gilera ice and watching the steps as I do it, you guys have done an amazing job very easy to keep up with, I'm putting on the malossi flip exhaust and a dellorto 19mm carb and multivar 2000 variator kit. do you mind of I imbed this video onto our forum? cheers from nz Terry
Thank you so much! The extra parts youn are fitting will be on another level. Yes please go ahead and link the forum. We are trying to get more SUBS and views, much appreciated.
hey guys the first section of the video, where you install the exhaust and the new jets and the tweaks to the clutch, can i get that done without adding the header kit?
Merci de noter cela, nous retirons toujours l'extrémité finale du tuyau lorsque le moteur est au ralenti et vérifions que l'huile circule jusqu'à l'extrémité du tuyau d'huile.
@scooterstreetau cheers, I’ve got a Leo vince on order , I don’t actually have an impact to get the clutch nuts off, would I be able to get away with fitting the TT pipe, up jetting, and lightening rollers , and then riding it to the garage to get the clutch fitted? Or would the bike just be too slow off the start without the TT springs to even ride it? I have bought a new clutch and was going to change the clutch springs my self then just get the garage to fit the new clutch with the Leo vince springs already in .
@@scooterstreetau yeah all the parts will be going on, just wanted to know if it would be ok to ride it to the garage without doing the springs as they are gunna do the springs for me👍
This titorial made me have the balls to buy a 70cc malossi sport to my Piaggio zip 02 2t... Finished it yesterday and tried it on today. I listened to my friend regarding to the jet, he told me mid 90s but i habe a 96 now and i cant even lile gove it more then 1/4 of gas before it starys to like blurr and lost power . I will try a 88 jet tomorrow. And also order a weight kit. I already have a jet kit. I also have a malossi fly clutch with bell i have to put on. But thinking i had to run in the new malosssi cylinder first? Thanks for this video much appreciated ❤❤💯💯
Well done! and a great achievement to have a go, I am sure it will be a success. With the basics, only ever change one part at a time, cylinder first then a quick start, then start the jetting. Start at your 96 and then move down to the 92-90-88 and when it becomes clean on throttle go back up 1 jet and ride it for a fuel tank and then retune. Yes you will notice the revs and movement may not be at their peak so leave the rollers and just add tighter clutch springs or the Mal clutch. and then again test ride and let it settle, adjust as necessary. Then repat with the next part and so on🚀
Yesterday I assembled the cylinder. As if I did everything well, I think I put the rings on well. I did cylinder break in today. For the first five minutes, I let it work on idle speed. I let it cool completely. Now it starts very hard, Fires up, works for one second and then goes out. What could be the problem? Could it be the seize? Also it has very high compression
hello, I'm back with a new problem, I installed a new cylinder and after 3 days the scooter didn't go even at maximum acceleration for more than 20 I took off the cylinder, it has small scratches, they can't be felt on the nails, they are only visible, one is towards the exhaust, it feels a little bit but I don't think it has cv, the engine is still running in and I respected 30kph, quality oil, motor 710, what would be the problem? The factory air filter is clean, what caused that wear?
@@scooterstreetau yes, the oil pump does not use a bag, 25 ml per liter in the tank, the first time the spark plug was dark brown and wet, I opened the carburettor half a turn and after about 15 minutes of driving, the spark plug was a little black on the top electrode, but the rest was colored from the factory of the spark plug
Brilliant video. Am after a bit of help with my zip my set up is stage6 70sport kit Stage 6 variator with 5.25 gram rollers Leo vince black edition race pipe 19mm carb with a 95 size jet malossi gear up kit standard crank and standard clutch set up the needle setting is 2nd from bottom standard reeds with a bigger inlet manifold the thing is the engine is spluttering on set off but as the revs build up it seems fine and is very quick. Any help would be much appreciated Cheers
i have a question, when i am riding and suddenly break very hard and stop, my moped dies if i dont rev it while breaking. otherwise drives very good and mixture and everything is correct
You may have an issue with the carby or fuel related. This could be the choke, an air leak in the rubber that is jolted when braking or carb setting need adjusting. Even worth checking the wires to the stator and the connectivity.
Perfect video easy to understand explanation, I’m looking at modding up my tnt Roma 2t I believe it has a Yamaha 2 stroke, would these parts (mainly the exhaust and cvt parts) be easily compatible with it? Thanks!
Hello, i have a dellorto 17.5mm on my piaggio zip and it spits fuel into the air intake and often floods the engine after fueling up and mixing the fuel what could be the issue my main jet is 74
Thks four your excellent job I have a Piaggio Zip I like to fix a Malossi 70cc kit on I have a Sp3 Liovince exhaust de restrict can you please let me know whitch carburettor jet size is work better thank you very much
It would be somewhere between 80 and 90. You need to get a range of jet sizes (jet kit), start at around a 90, test ride, reduce to the next size down, repeat until the bike runs cleanly. Taking a shot in the dark on a jet size is very commonly the cause of piston seizure.
I watched this video as a guide to install my Polini 70cc, with a Technigas silent pro exhaust and 17.5mm dellorto carburetor with a free flow air filter... I was just asking that how my jet size has gone from 84 to now 115, and it runs everything better but like, I had the 84 for quite some time and it thought it had enough several times, because it was running too lean. Fixed the lean issue and hoping that I don't have to open the engine this time.
Thanks B.E. yes true! the free flow air filter (POD) will require large amounts to fuel to balance the fuel air mix. You may also require lighter rollers to build RPM. 84 is very lean for that type of air filter, so I am glad to hear you tuned out the issues👍
@@scooterstreetau it just took two pistons to me to realize that was the problem. And I highly considering by buying a new 70cc Polini Sport kit, just so I can drive in peace without myself worrying about it. It has survived now closer to 1000km with that piston, record for that moped on one pistol so far, but what worries me is the vertical lines inside on the cylinder. I have a camera that I could stock through the spark plug hole and see the problems...
@@scooterstreetau oh sorry, i meant a electronic speed limiter. It’s two cables, one is going to be on the battery but where do i put the other cable? Im also having a service on the variator with a new belt. The old length on the belt was 711 i think, the new is 732. I been driving carefully 100 km with it and it wont have the same acceleration. I feel the belt is not gripping as good as the old belt. Is it because of wrong belt length or can it be something else? Keep up the great work on the channel, videos is very informative to watch and im learning a lot about scooters when watching😃
@@crazyhcr2701 Speed Limiter: Please ask the seller for instructions before proceeding.. Are there any instructions for the rev limiter? Some of these will connect to the battery and the other wire to the wire from Stator to CDI.
@@crazyhcr2701 Belt Length: The belt position is crucial to acceleration from the start, it needs to sit down in the front pulley (Variator) as much as possible and high on the rear pulley. If you fit a longer belt it may sit higher on the front pulley especially if it is thicker and this will give a higher gear take off, the feeling will be a slower acceleration. This is where shims can be added to the Variator shaft. Get the belt height checked at its starting position on the Variator..
I have a Aerox 2016m and i have a hard time understanding what weights you should put. Like if i have a Extra exghaust and a Variator kit MALOSSI MHR 2000 Multivar MINARELLI what kind of weights shoul i use. And a last question I have a 12mm carb if i do these upgrades should i put in a larger carb ?
The larger carb will be an advantage with the sport exhaust. With the roller weights use the ones Malossi recommend and if you want to use different weights trial with a 10% change per roller. Trail and testing is best.
@@vetleandrisen6861You ask the same question twice, we don't. Only in the Race Scooters we used Pre-Mix ! Doing it for over 20 years and that has not happened.
Have a question regarding if possible to change my vespa et2 from AC to DC so I could turn the entire scooter lights into LED including odometer lights cannot seem to find a good tutorial video anywhere to even see if it could be done?
@@Octavian17 You must tune it, always tune it if you make an adjustment that relates to fuel or air or capacity of the engine. This rule should always be applied.
I HAVE THE SAME SET UP EXACTLY, CAN YOU PLEASE SUGGEST HOW MANY TURNS OUT SHOULD THE AIR MIXTURE BE? THERE ARE NO VIDEOS ON TH-cam ON HOW TO ADJUST A PHBG 19 CARB! IM NOT SURE IF YOU HAVE THE SAME CARBURATOR AS ME
@@XavierMauViegasIf you watch the video you will see we show how the Squish is tested. 36:00 We find the consistency with the Malossi product is precise. BUT!!! regardless of if the Manufacturer has a set dimension we have learnt from many experiences that you should always check.👍
My Leo Vince TT doesn’t fit my 2020 TaoTao 49cc pony scooter. On the exhaust port side from the motor. If, I upgraded my cylinder what should I get to get the right angles to mount to that exact same performance exhaust! Please help. Thanks in advance for info & suggestions. I’m at a stopping point at the moment!
It depends which model of the TT you have ordered, and whether your scooter is a 2 stroke or 4 stroke. We don't have that model in Australia, but upon a quick google is appears to be 4 stroke.. please confirm.??
@@scooterstreetau yes, it’s a 4 stroke. Oem exhaust mount is basically straight up & down. The Leo Vince has a major curve to were it’s supposed to mount to my engine exhaust port. Not happening inless some major welding is done to the new exhaust or cylinder must be changed out.
@@fitzwater504 The Leo Vince TT is a 2 stroke exhaust, even if modified to bolt up it will not suit that bike. Most of the 50cc 4 stroke Chinese scooters use the 139QMB engine. Check your engine prefix to see. If it is, you'll need a Leo Vince Hand Made 4 stroke exhaust.
@@fitzwater504 Unfortunately there arent many options to get that bike going any faster. A Malossi variator will often help acceleration and maybe get a couple more top speed, outside of that your only realistic option is a larger cylinder kit. Big job, will make a significant difference.
@@scooterstreetau Leo Vince TT handmade Ref # 4053 looks to be exactly what you had put on yours. Just a different setup. Thanks looking at big bore kits.
I have a yazuni r exhaust on my zip with malossi cylinder kit 70 and malossi clutch and variation kit. I have a 17.5mm carb with 70 main jet. I'm not worried about top speed as much just want quick takeoff. but when pulling throttle it takes a full turn and 2 seconds to Start off. and starts off slow. would u say this is a rollers issue or clutch springs? or anything else. btw love the videos wouldn't be able to do my setup without u guys
Thanks for the love👍, Try 6.1 gram rollers and use the Polini clutch if you can. The delay is due to the clutch spring, and it needs delay to build rpm before engaging for faster acceleration. It the exhayst derestricted? Use a large jet (Tune carby) and fit a pop stuffer in to the air box cover. Lets get the rpm really high so it can be delivered to the rear wheel.
Hey guys just fitted a Leo Vince tt pipe to my 50cc piaggio, aswell as malossi 5.5g rollers, green polini clutch springs and a 62mm carb jet. First take off the ride was snappy as, then after that it just bogs right down and is slower than when it was stock. When I rev it I can feel a vibration right as the clutch should engage. Should I put heavier springs in? Or is it to do with the rollers being too light? This is all new to me so any help appreciated, thanks guy.
@@scooterstreetauso I’ve put the yellow springs in, and put 3 of the stock rollers back in and no real difference, still slower to take off than it was stock
@@RotaryKiwi you need to keep trying. I would have the scooter running perfect before fitting any ew parts. Then fit the higher tension clutch springs. Now fit the pipe and tune the carby, start rich and then lean it off. Test ride and then tackle the transmission rollers. Rollers, start with factory and then 1 gram lighter for each roll.
@@scooterstreetau i looked it up on your shop, and its not the same end for the zip model, the one in the vid is just a regular, but for the specifif zip model its longer, just check it up
Whats the best setup for a leovince tt on a piaggio zip? Which main jet, rollers, and clutch springs? I want it to be optimised so not so much agressive more calm if you understand. Thanks!
Main jet needs to richened and then trial several sizes to find the best suited for your scoot. Rollers around 6.5 gram rollers. Polini adjustable clutch start on 2nd notch at adjustment.
@@numankralj You need to get in and see what you have, probably the standard 6mm 53. start at 70 and jet down from there. Watch the carby jet change vidoes to see the method.
@@scooterstreetau about the clutch sprigns witch are the best? The green or yellow or blue? I kind of want my zip to start faster so.. the green is from 4000 to 5500rpm the yellow is from 5500 to 6500rpm and blue from 6500 to 7500rpm or should i use the ones that are given by leovince?
@@scooterstreetau and can i just put a sitoplus exhaust (the long one that works best with 70cc) without tuning nothing else so just puting on that exhaust and will it run properly and what top speed will it have
The best video. You are the best! But tell me, at a 2001 Aprilia Sr 50 AC I manage to do it on the street combining with a 70 cc Malossi engine set, with an RMS trim ?? Thank you. hello from Romania.
Enjoyed watching the video Iam wondering how much of the performance increase was down to derestricting the carb would like to have seen this before fitting the exhaust.
Thank you mate👍. If you derestrict the carb only there will be no noticeable gain, due to the balance being over weighted with air. In effect you are giving too little fuel. We want an increase but a balanced ratio of fuel and air. Thanks for the SUB🎅😎
Hey guys, quite obsessed with your TH-cam channel at the minute can’t stop watching the vids, my dad and I just bought a 2009 Piaggio Zip. We have the yasuni R derestricted and malossi variator for now. We need to derestrict the bike, I’ve watched a video of yours where you take that plate out but I need help on choosing a new main jet for the carb? Do you have any recommendations please I saw on one video you guys put a 62 jet in but that currently means nothing to me I’ve looked on our local website and there are 5mm jets 6mm jets etc? I hope this makes sense and any help is appreciated thanks from England 🇬🇧
Hi Callum, what a great message, thanks buddy👋👍. With the Yasuni R you should have already: Upgraded the jet size, adjusted the rollers and added clutch spring set. You Should remove your current jet and heck the sizes to get up to speed with the size lingo. The Zip has 6mm jet with a size of 53. You should start with a jet size of 62 and move from there.. it is important to do the other small parts I have mentioned..
@@scooterstreetau thanks for the speedy response guys, haven’t fitted any parts just yet I just wanted to make sure I got everything together first before we tackle the job. Thanks for your advice guys I’ll start with the 6mm 62 jet
Hi there, back again we finally fitted the parts to the scooter. Malossi variator with 7.5Gram rollers and added yellow clutch springs as well as the yasuni exhaust. Fitted a new carb as well as the other one had been abused and the thread on the main jet had been stripped. Took it for a ride out yesterday and acceleration was weak and top speed to 60 kph. Also main jet size is around a 65 jet according to the box on the new carby. Hope you could shed some light on how I can fix the slow issues. Appreciate your knowledge
Do you guys work on bikes for people my piaggio zip 70cc won’t start if I run straight petrol to inlet it will I put carb on no petrol getting thru and i have put 2 new carbs on !
Yes we do. You need to test the fuel tap and check for fuel flowing to the carby when under vacuum pressure (cranking), if it is not working it must be replaced. If it is working then go to next step..

Hi Callum, Thank you so much for the Coffee, so appreciative. What Yasuni? Z or R? Did you derestrict the exhaust? Move rollers to 5.5 gram. then move up or down in weight as required. 5.5 may be too light but you will know first ride. Let the carby warm up so it is not on choke. ride for 3 minutes then tune and judge. D you have a 70cc kit fitted?

Hi I have a zip 2 stroke with a de restricted pm360 pipe I am running a 19 or 17.5 carb with stock air box and the 70 kit featured in this video what are the best jets got this I already have yellow clutch spring Brand new variator malossie with 7.5 rollers Just need to know the best jet to run and do I change pilot And what are thefe best air screw turns and idle turns
Hello Jr Vlogs, thanks for comment. You can try slightly lighter rollers. 7g. The air mix screw should be 3/4 - 1 turn out. Do not adjust this in an attempt to tune the carby, this is standard for 50cc or 70cc. The main jet is 88 for 2 week period, skip the video to 52:00 for a run down. After 2 weeks we followed up with a systems check and retune, we finished the carby with an 85 main JET, Needle is an A22 Middle notch. We did not change the pilot jet. Your scooter will need to be tuned for the parts you fitted. Do not accept what we used as the final word, tune it as your engine requires👍
If the cylinder kit is fitted and TUNED correctly, you will have years of good riding. On the other hand if not done properly you will be crying on your motionless scooter.
Which jets do you recommend on piaggio zip 2t, with a tuned exhacust, and a polini clutch, and all the limitations is out?! and my carburetor is a 17.5 mm...

It depends on what model scooter you have, but generally not unless you install a racing cylinder kit. If yours is a Piaggio engine like this, the factory crank is very strong.
best tutorial i have seen in years great work!!!!
Thanks for your appreciation👏😊
My fav part is they aren’t using torque specs, I never been a fan of them 😂 always though who cares if it’s for my scooter
You guys make a great instructional video, it was just a pleasure to watch! ☺ I'm 66 and still fiddling about with scooters and other two strokes, mainly veterans. But my son has a Zip that got scored, so he's putting on the same Malossi sport cylinder. Already had the same exhaust, Leo Vince. So he was over the hill when I sent him a link to this video.. A very professional video production, and you blokes are entertaining. Thanks !
Thanks MrWhiteamin, appreciate the kind words mate👏 The Zip is an amazing little scooter, heaps of fun for street riding.
62 and still love building fast 2 stroke scooters
Two true professional's, great video footage and extremely well explained. Well done guys
Thanks Brett🙌 awesome comment!
NO WAY! I never been so proud to be italian like today hahah. Well done guys, it's so satisfing that Zip is loved till Down Under. I'm now subscribed :)
What a beautiful comment! Thank you Giuseppe Bonaviri. We love Italian Scooters in Australia🛵
@@scooterstreetau this is one more reason for me to come there 😁
I've been pretty experienced tuning small 2 strokes with manual gearboxes. And I got myself my first ever scooter a couple months ago and it's been really hard for me to tune my rollers, clutch bla bla. This video is definetly very informative about how this stuff works. I am confident that I again can take upon the challange and get this thing running like it should.
Go for it! Test and learn, can't go wrong. Be warned, once you start it is hard to stop tuning.
Guys, massively appreciate the video. It was so comprehensive and I came out with a whole lot more knowledge. Thank you so much and I wish you all the best.
Amazing to receive such a complimentary comment, thank you Charles. All the very best for you too👍🦘🦘

Thats the most cleanest zip 2t i have probely ever seen in my life . All the other ones got damage or are customized. That exhaust is pretty good though. Would not have expected that.

Great feature length episode guys. Looking forward to seeing more similar content.
Who doesn't love changing clutch springs? 😂
Paul, thanks for the support :) More Vids in the pipeline.
Does this kit change your auto transmission to manual?
Reminds me of the old days. One day i walked up to the nearest motorshop i always got my stuff. Walked up to that guy and asked him that i was looking for a Polini EVO 70CC for Piaggio. Back then the kit to have (15+ years ago or so). I saw his eyes grow and the next thing he said to me "What the Heck do you need that Kit for??" i imediatly realised i was not going to get that Kit at that time. His reaction on my question was priceless, something i have never forgotten. :) At some point i ended up having the desired kit and it was great fun. Just dont get caught when you run it in the streets.
Good story Johan, 15 years ago only Scooter tuners would have known of these parts😜. The first time someone asked me if I had any Polini stuff I pointed towards the fruitshop down the road.😂
The inlet plate in the carburettors mouth (brass plate) is not a restrictor, it’s actually serving its purpose delivering air flow into the right areas of the carb through the air holes. Often people believe it’s restricting the flow of air, but after performance parts get the jetting right with this little plate still in you will be onto a winner👍🏻 try with and without you’ll notice the sharper response and reliability from keeping the plate as is
Thank you, really appreciate your experience... keeping it in does give better fuel consumption👍
i have been struggling with my vespa sprint for a while i normally only work on classic scooters but now thanks to you guys i found a couple of my bikes problems and got some really good tips. thank you so much!
Really good to hear this. We struggled for many years trying to pioneer solutions to the many problems these little scooties present.

Excellent ! ...well done ! 👍
Thank you👌
Just to be fair, I have enjoyed thoroughly the video and brought fond memories back :)
Just to point out when you talk about "this isn't ideal to go super fast" perhaps you ought to know that there is a quite active racing scene where these little buggers go up to 160 Km/H
Thank you, and yes we are aware of the Zip race series. Are the race Zips the SP water cooled version? This one is air cooled base model version.
@@scooterstreetau Absolutely correct, the SP is the water cooled one, but to the best of my knowledge it should be possible to convert any version to liquid cooling: the only hiccup would be with the clearances in the leg shield trim, as there's a storage compartment that would interfere with the radiator's positioning. For the sake of honesty though, I'm not going to vouch about the accuracy of the info, it's something I recall from when the SPs where just hitting the market in Italy some 10+ years ago
@@LucaFiltroMan We have done this conversion. We took an air cooled Zip and fitted the Radiator with electric water pump, cooling hoses and the water cooled racing cylinder along with many other tuning parts. We also changed the front panel and fitted a genuine SP front cover so the incoming air could meet the radiator. The performance was as you described, Ridiculous power!! This was an expensive project... We lalso did the Superman theme custom paint job and it did fly🤣🤣.
does the piaggio zip have the same engine as the aprilia sr50 2019?
You probably noticed apart from the water cooling system on the SR50R, the base of the 2 engines are the same. You will notice between the Piaggio/Aprilia 2T models they look the same but each model has a different transmission length to accommodate the rear wheel, this includes each model running a different belt size to connect variator to the rear pulley.
I believe 2019 SR50R has the new Euro 4 emissions system also, which uses a different carburettor, stator, coil and CDI/ECU. It also has the larger temp sensor on the head, and the solenoid air valve for the electronic control of the carb.
@@scooterstreetauwith the length difference would it be worth sourcing the longer transmission to help with wheel lift?
Yes if that is the goal.@@jaredpursey3791
Well done guys, super happy with all of my purchases and support
Thanks for your support! All the best.
Wow had a severe case of nostalgia kicking in watching this, i’m from belgium and almost 38 but was doing the exact same thing since i got my first mobilette called the honda camino at the age of 16 , ended up going to school learning all of it and not just placing parts etc, now after 2 strokes i suffered at 34 wich paralized my left side so its kind of hard to watch without feeling the pain of damn the days where i was ok but it feels great!, you got yourselves a huge fan!, in my days it was either the dick ring or just dick for the exhaust🤣 how are the laws on tuning scooters in australia? We had cops stopping you randomly where they were standing near a random road with a portable speedometer to check 😫 they confiscated it to give you permition like a month or god knows how long to pick it back but with all the illegal parts removed for you by their own pissed off mechanic if you catch the drift lemme go check your ig out peace!
Gday mate and welcome, Great comment thank you! See you're never alone😁😂.In Aus we do not have these rules, the country only adopted emissions rules 12 months ago.🦘
Wow and the Cops remove the parts? Hard core.. Over here no such thing, only speed and Hooning laws. All the best🛵🛵

Im lamost there brother!! Messing around with weights i have 6.5g at the moment. Think i will try 6g and contemplaining to put the malossi fly clutch with bell on.
Great stuff, very happy for you😆. Note: The lighter rollers will allow the engien to rev easier but go too light and you will loose pulling power through the mid range. Fitting a clutch or fitting tighter clutch springs will make a positive difference to the rpm build and the initial acceleration.
@@scooterstreetau im so happy for your existence and that you made this video 💯❤️ you helped a man on the other side of the world literally 🙏🙏🙏

when i put on the exsast and the variator kit with a 72 in the carb it almost dosent go forward. what can the problem be
Your issue is very common, you have not made all the required changes to the engine. Go back to the start, remove all the parts and fit only the Variator first and then test ride. If all is OK then move to the next step. When we fit an exhaust you should watch one of earlier videos to see what other parts MUST be changed to get satisfactory result. Also watch the clutch springs set fitting video.

@@generalr6398 Ok thank you, use the vid above as a guide..
the "emission controller" is actually there to provide a certain amount of oxygen in the catalysator that is in every single stock pipe in european bikes, and theres a check valve so that the exhaust gasses dont go into the variator case or where ever the pipe takes the air from
what a great vlog, love it

Great video guys. Thanks from the UK, please let me know if you had to move the needle clip.
Hey thanks henryhaxby, see the description for the tuning points. we start with needle clip in middle position and we leaft it in this position.
Nice video guys thanks, i recently buy a zip 2t stock!
Where is the serial VIN?
In the glove box.
Good choice! Great place to start, 😍 ZIP
There are two types Dellorto PHVA 17,5 models.
A modified "low emission" type named "OD" with a fat needle, smaller cut away and different needle jet (emulsion tube)
The other one is the "normal" one named "TS. Thats the one to go with. Much more easy to tune in, especially in the middle range.
Thanks EnergyXyx, this is great information🙌. There are more than 11 PHVA in 17.5mm range. Parts change between them such as the slides, needles, atomisers, jets and so on. Heaps of info on Dellorto Uk website for anyone needing.

My scooter wont gear down when driving uphil, any idea whats happening and how i could change it
Hi Robin, I've replied to you on another thread for the same question😁
my 2006 zip doesn't have an emissions part fitted ... i like your upgrades !!
Yes the early Zip was PURE. Thanks for watching🙌
How would I go about changing the springs on a clutch with no holes to screw it down to a table? The bottom of my clutch has no holes
Use the inner mounting hole.
@scooterstreetau cheers, I’ve got a Leo vince on order , I don’t actually have an impact to get the clutch nuts off, would I be able to get away with fitting the TT pipe, up jetting, and lightening rollers , and then riding it to the garage to get the clutch fitted? Or would the bike just be too slow off the start without the TT springs to even ride it? I have bought a new clutch and was going to change the clutch springs my self then just get the garage to fit the new clutch with the Leo vince springs already in .
@@420-p8l As long as at 1 point all of the parts are fitted and adjusted otherwise it will not run well!
@@scooterstreetau yeah all the parts will be going on, just wanted to know if it would be ok to ride it to the garage without doing the springs as they are gunna do the springs for me👍
@@420-p8l Yeah it will be fine.
This titorial made me have the balls to buy a 70cc malossi sport to my Piaggio zip 02 2t... Finished it yesterday and tried it on today. I listened to my friend regarding to the jet, he told me mid 90s but i habe a 96 now and i cant even lile gove it more then 1/4 of gas before it starys to like blurr and lost power . I will try a 88 jet tomorrow.
And also order a weight kit. I already have a jet kit.
I also have a malossi fly clutch with bell i have to put on. But thinking i had to run in the new malosssi cylinder first?
Thanks for this video much appreciated ❤❤💯💯
Well done! and a great achievement to have a go, I am sure it will be a success. With the basics, only ever change one part at a time, cylinder first then a quick start, then start the jetting. Start at your 96 and then move down to the 92-90-88 and when it becomes clean on throttle go back up 1 jet and ride it for a fuel tank and then retune. Yes you will notice the revs and movement may not be at their peak so leave the rollers and just add tighter clutch springs or the Mal clutch. and then again test ride and let it settle, adjust as necessary. Then repat with the next part and so on🚀
Yesterday I assembled the cylinder. As if I did everything well, I think I put the rings on well. I did cylinder break in today. For the first five minutes, I let it work on idle speed. I let it cool completely. Now it starts very hard, Fires up, works for one second and then goes out. What could be the problem? Could it be the seize? Also it has very high compression
Did you do all the system checks before changing the cylinder? Did you change the jet?
hello, I'm back with a new problem, I installed a new cylinder and after 3 days the scooter didn't go even at maximum acceleration for more than 20 I took off the cylinder, it has small scratches, they can't be felt on the nails, they are only visible, one is towards the exhaust, it feels a little bit but I don't think it has cv, the engine is still running in and I respected 30kph, quality oil, motor 710, what would be the problem? The factory air filter is clean, what caused that wear?
Over heating causes the scratching. Was the carby over jetted and the oil system working optimally? Did you check these things?
@@scooterstreetau yes, the oil pump does not use a bag, 25 ml per liter in the tank, the first time the spark plug was dark brown and wet, I opened the carburettor half a turn and after about 15 minutes of driving, the spark plug was a little black on the top electrode, but the rest was colored from the factory of the spark plug

Any help would be much appreciated Cheers
Thank you Joe🙌 Let the engine warm up to operating temp before making a judgement on the tuning. Is it auto choke or manual choke?
i have a question, when i am riding and suddenly break very hard and stop, my moped dies if i dont rev it while breaking. otherwise drives very good and mixture and everything is correct
You may have an issue with the carby or fuel related. This could be the choke, an air leak in the rubber that is jolted when braking or carb setting need adjusting. Even worth checking the wires to the stator and the connectivity.
Very nice video
Thanks Dom, appreciated🤙

Hello, i have a dellorto 17.5mm on my piaggio zip and it spits fuel into the air intake and often floods the engine after fueling up and mixing the fuel what could be the issue my main jet is 74
Check the fuel tap and float level.
Thks four your excellent job I have a Piaggio Zip I like to fix a Malossi 70cc kit on I have a Sp3 Liovince exhaust de restrict can you please let me know whitch carburettor jet size is work better thank you very much
It would be somewhere between 80 and 90. You need to get a range of jet sizes (jet kit), start at around a 90, test ride, reduce to the next size down, repeat until the bike runs cleanly. Taking a shot in the dark on a jet size is very commonly the cause of piston seizure.
I watched this video as a guide to install my Polini 70cc, with a Technigas silent pro exhaust and 17.5mm dellorto carburetor with a free flow air filter... I was just asking that how my jet size has gone from 84 to now 115, and it runs everything better but like, I had the 84 for quite some time and it thought it had enough several times, because it was running too lean. Fixed the lean issue and hoping that I don't have to open the engine this time.
Thanks B.E. yes true! the free flow air filter (POD) will require large amounts to fuel to balance the fuel air mix. You may also require lighter rollers to build RPM. 84 is very lean for that type of air filter, so I am glad to hear you tuned out the issues👍
@@scooterstreetau it just took two pistons to me to realize that was the problem. And I highly considering by buying a new 70cc Polini Sport kit, just so I can drive in peace without myself worrying about it. It has survived now closer to 1000km with that piston, record for that moped on one pistol so far, but what worries me is the vertical lines inside on the cylinder. I have a camera that I could stock through the spark plug hole and see the problems...
@@basicallyedward Your not alone, for a daily I prefer to use a modified air box.
@@scooterstreetau yeah but what you guys say about vertical lines on my cylinder?
@@basicallyedward There should not be lines on the cylinder. When you run lean with an under fuelled system damaged is caused due to excess heat.
Wondering if it’s possible to install a rev limiter on these bikes, so it only goes 45 kmh?
Yes, add thick washer to the variator shaft..
@@scooterstreetau oh sorry, i meant a electronic speed limiter. It’s two cables, one is going to be on the battery but where do i put the other cable?
Im also having a service on the variator with a new belt. The old length on the belt was 711 i think, the new is 732. I been driving carefully 100 km with it and it wont have the same acceleration. I feel the belt is not gripping as good as the old belt. Is it because of wrong belt length or can it be something else?
Keep up the great work on the channel, videos is very informative to watch and im learning a lot about scooters when watching😃
@@crazyhcr2701 Speed Limiter: Please ask the seller for instructions before proceeding.. Are there any instructions for the rev limiter? Some of these will connect to the battery and the other wire to the wire from Stator to CDI.
@@crazyhcr2701 Belt Length: The belt position is crucial to acceleration from the start, it needs to sit down in the front pulley (Variator) as much as possible and high on the rear pulley. If you fit a longer belt it may sit higher on the front pulley especially if it is thicker and this will give a higher gear take off, the feeling will be a slower acceleration. This is where shims can be added to the Variator shaft. Get the belt height checked at its starting position on the Variator..

Hi from the USA 😅
Hey Bro🙌
When going to the 70cc ,do you have to adjust your oil pump to allow more oil? Or will the fuel to oil ratio be the same? Thank you
I don't, I ensure it is working well and has no leaks or questionable oil hoses in or out.
I have a Aerox 2016m and i have a hard time understanding what weights you should put. Like if i have a Extra exghaust and a Variator kit MALOSSI MHR 2000 Multivar MINARELLI what kind of weights shoul i use. And a last question I have a 12mm carb if i do these upgrades should i put in a larger carb ?
The larger carb will be an advantage with the sport exhaust. With the roller weights use the ones Malossi recommend and if you want to use different weights trial with a 10% change per roller. Trail and testing is best.

@@scooterstreetau yes, it’s a 4 stroke. Oem exhaust mount is basically straight up & down. The Leo Vince has a major curve to were it’s supposed to mount to my engine exhaust port. Not happening inless some major welding is done to the new exhaust or cylinder must be changed out.
@@fitzwater504 The Leo Vince TT is a 2 stroke exhaust, even if modified to bolt up it will not suit that bike. Most of the 50cc 4 stroke Chinese scooters use the 139QMB engine. Check your engine prefix to see. If it is, you'll need a Leo Vince Hand Made 4 stroke exhaust.
@@fitzwater504 Unfortunately there arent many options to get that bike going any faster. A Malossi variator will often help acceleration and maybe get a couple more top speed, outside of that your only realistic option is a larger cylinder kit. Big job, will make a significant difference.

Thanks for the love👍, Try 6.1 gram rollers and use the Polini clutch if you can. The delay is due to the clutch spring, and it needs delay to build rpm before engaging for faster acceleration. It the exhayst derestricted?
Use a large jet (Tune carby) and fit a pop stuffer in to the air box cover. Lets get the rpm really high so it can be delivered to the rear wheel.

First take off the ride was snappy as, then after that it just bogs right down and is slower than when it was stock.
When I rev it I can feel a vibration right as the clutch should engage.
Should I put heavier springs in? Or is it to do with the rollers being too light?
This is all new to me so any help appreciated, thanks guy.
You must fit heavier springs! trial the roller 5.5 may be too light.
@@scooterstreetauso I’ve put the yellow springs in, and put 3 of the stock rollers back in and no real difference, still slower to take off than it was stock
@@RotaryKiwi you need to keep trying. I would have the scooter running perfect before fitting any ew parts.
Then fit the higher tension clutch springs. Now fit the pipe and tune the carby, start rich and then lean it off.
Test ride and then tackle the transmission rollers. Rollers, start with factory and then 1 gram lighter for each roll.
Hello, one question, the yazuni z for piaggio zip has a very long end (the cyllinder mount side), i have never seen it before, do you know why?
Watch this video, the header length is very similar to other exhausts.... th-cam.com/video/mtc6RtfBxco/w-d-xo.html&ab_channel=ScooterStreet
@@scooterstreetau thanks, i allready have seen it, but if u searxh up «yazuni z piaggio zip» you ser that the end is larger than the ones in the video
@@eliaslien-hgeland457 The Exhaust in the Video are all for Piaggio..
@@scooterstreetau i looked it up on your shop, and its not the same end for the zip model, the one in the vid is just a regular, but for the specifif zip model its longer, just check it up
Will this get up a residential steep hill with 2 adults?
Describe the hill and describe the adults.
Can you please show how can you remove air out of oil lines on Sr 50 R Hi-PER 2 please!
Yes will make a good video. Use a syringe and push oil through the lines.
Whats the best setup for a leovince tt on a piaggio zip? Which main jet, rollers, and clutch springs? I want it to be optimised so not so much agressive more calm if you understand. Thanks!
Main jet needs to richened and then trial several sizes to find the best suited for your scoot. Rollers around 6.5 gram rollers. Polini adjustable clutch start on 2nd notch at adjustment.
@@scooterstreetau what about the main jet? I dont know if for my zip is 5mm or 6mm. I have a dellorto 17.5 carb
@@numankralj You need to get in and see what you have, probably the standard 6mm 53. start at 70 and jet down from there. Watch the carby jet change vidoes to see the method.
@@scooterstreetau about the clutch sprigns witch are the best? The green or yellow or blue? I kind of want my zip to start faster so.. the green is from 4000 to 5500rpm the yellow is from 5500 to 6500rpm and blue from 6500 to 7500rpm or should i use the ones that are given by leovince?
@@scooterstreetau and can i just put a sitoplus exhaust (the long one that works best with 70cc) without tuning nothing else so just puting on that exhaust and will it run properly and what top speed will it have
If you change to 70cc what are the thongs you also need to change
Hi, Watch the video from the start to finish, we list and show all of the parts we use for this build.
The best video. You are the best! But tell me, at a 2001 Aprilia Sr 50 AC I manage to do it on the street combining with a 70 cc Malossi engine set, with an RMS trim ?? Thank you. hello from Romania.
crankshaft RMS
Yes you can do it.. Thank you for supporting us👏
Enjoyed watching the video Iam wondering how much of the performance increase was down to derestricting the carb would like to have seen this before fitting the exhaust.
Thank you mate👍. If you derestrict the carb only there will be no noticeable gain, due to the balance being over weighted with air. In effect you are giving too little fuel. We want an increase but a balanced ratio of fuel and air. Thanks for the SUB🎅😎
Hey guys, quite obsessed with your TH-cam channel at the minute can’t stop watching the vids, my dad and I just bought a 2009 Piaggio Zip. We have the yasuni R derestricted and malossi variator for now. We need to derestrict the bike, I’ve watched a video of yours where you take that plate out but I need help on choosing a new main jet for the carb? Do you have any recommendations please I saw on one video you guys put a 62 jet in but that currently means nothing to me I’ve looked on our local website and there are 5mm jets 6mm jets etc? I hope this makes sense and any help is appreciated thanks from England 🇬🇧
Hi Callum, what a great message, thanks buddy👋👍.
With the Yasuni R you should have already: Upgraded the jet size, adjusted the rollers and added clutch spring set.
You Should remove your current jet and heck the sizes to get up to speed with the size lingo. The Zip has 6mm jet with a size of 53. You should start with a jet size of 62 and move from there.. it is important to do the other small parts I have mentioned..
@@scooterstreetau thanks for the speedy response guys, haven’t fitted any parts just yet I just wanted to make sure I got everything together first before we tackle the job. Thanks for your advice guys I’ll start with the 6mm 62 jet
@@callum14p Great plan👍
Hi there, back again we finally fitted the parts to the scooter.
Malossi variator with 7.5Gram rollers and added yellow clutch springs as well as the yasuni exhaust. Fitted a new carb as well as the other one had been abused and the thread on the main jet had been stripped. Took it for a ride out yesterday and acceleration was weak and top speed to 60 kph. Also main jet size is around a 65 jet according to the box on the new carby. Hope you could shed some light on how I can fix the slow issues.
Appreciate your knowledge
Do you guys work on bikes for people my piaggio zip 70cc won’t start if I run straight petrol to inlet it will I put carb on no petrol getting thru and i have put 2 new carbs on !
Yes we do. You need to test the fuel tap and check for fuel flowing to the carby when under vacuum pressure (cranking), if it is not working it must be replaced. If it is working then go to next step..
Scooter Street ok I’ll give it a shot thanks m8
@@o1up570 Shweet.
I was thinking about doing a 70 swap on my Keeway, would i need to swap the crank or would the stock crank work fine?
Based on the Minarelli engine so you should be fine, just make sure there is no damage or wear on the crank and main bearings.
hello,i have yasuni r malossi delta cluch 4.3 rollers white spring malossi special belt malossi red air filter in box on aprilia sr 50R 2005 what jet should i get?
Start with a rich jet so you have a spluttering engine and lean off gradually.
Really interesting video, watched the whole thing. One question (which I couldn’t find in other peoples questions), would it be the same process for the Vespa 2 stroke 50cc? Thanks and greetings from UK
Hi, and thank you. Yes the Vespa 2 stroke and the Zip 2 stroke are the same engine..👍
Sur vespa s 50 2t avec vilebrequin malossi rhq et kit 70 malossi fonte Faut-il changer le gicleur de ralenti ou laissé celui d’origine 32?
Parfois, nous le changeons en 35. Faites ce dont vous avez besoin pour avoir un moteur qui fonctionne bien, vous pouvez ajuster la position de l'aiguille et également changer l'aiguille "A".
D’accord je vais faire ça merci beaucoup.
@@vinci679 Très bon
Hi there, back again we finally fitted the parts to the scooter.
Malossi variator with 7.5Gram rollers and added yellow clutch springs as well as the yasuni exhaust. And a malossi air/sponge filter
Fitted a new carb as well as the other one had been abused and the thread on the main jet had been stripped.
Took it for a ride out yesterday and acceleration was weak and top speed to 60 kph. Also main jet size is around a 65 jet according to the box on the new carby. This wasn’t good enough so had to swap the main jet to a 78! And this seems to have helped ever so slightly.
On this video you were getting 80kph with very similar parts. What do you think I’m doing wrong?
Hope you could shed some light on how I can fix the slow issues.
Appreciate your knowledge
Also tipped for a coffee guys hope you received it
Hi Callum, Thank you so much for the Coffee, so appreciative.
What Yasuni? Z or R? Did you derestrict the exhaust?
Move rollers to 5.5 gram. then move up or down in weight as required. 5.5 may be too light but you will know first ride.
Let the carby warm up so it is not on choke. ride for 3 minutes then tune and judge.
D you have a 70cc kit fitted?
@@scooterstreetau hey guys, it’s a Yasuni R that has been derestricted. Ok will try the rollers. Bike has always been running a few minutes before taking it out for a spin. It’s still a 50cc on the scooter for now.
Thanks again
@@callum14p Ok, the Yas R needs very light rollers with a 50cc kit, give it a go and let us know 👍👍
Do you guys prefer the zip or Aprilia sr50r? Is the Aprilia better for faster roads?
SR50R is a water cooled engine it produces more power and can handle higher top speeds.
Hello I have a zip 50 2t 2018 I have derestricted however I took of the air duct with goes over the air box. I have no clue where the opposite side goes do u think you could help
The other end just sits on the frame, it stays open to allow air to enter and not connected or closed off..
Great video guys, im just about to tune a zip myself, did you guys remove the restriction from the exhaust on this setup?
Tahnk you👍Yes.
Thankyou so much lads helped me alot !!!!
Awesome, great to hear..
Hi there,
Just wanted to ask a quick question: Does the 70cc Malossi Sport piston rings have any particular position where you placed them on the piston as I cannot see no markings at all on both of the rings.
Thank you.
Both rings are the same, so the position can be top or bottom. Read the instructions if unsure.
Takes me back 20 years watching this!
Do you guys have any original italjet dragsters in Australia?
I'm still tempted to do my stock minerelli engine out of mine in full malossi parts now!
Hi There, Yes we do have the Italjet Dragster in Aus, we have 4 customers with this machine. With the upgrade, Go for it bang it up and burn🏍🏍🏍
@@scooterstreetau great stuff! One of my all time favourite scooters! It's been off the road since 2007 as parenthood and mortgages have stopped play for that long but I think I will have to do it soon!
I have only just finished restoration on a italjet formula too!
@@charlieboy259 Great, yes very rare over here, 3 of the 4 we service are modified and really have plenty of power and such a unique style.

Bonjour peut-on rouler sans la petite rondelle crantée au bout de l’axe de l’embrayage qui se loge dans le roulement du carter de kick ? Car celle ci c’est cassé
Bonjour, tu parles de l'embrayage arrière ? Ou la poulie avant ? Sur le moteur Piaggio, il y a une rondelle dentée au niveau de la poulie avant. Voir la vidéo 6:50
Oui l’embrayage arrière,au bout de l’arbre de transmission qui se loge dans le roulement du carter de kick il y’a une petite rondelle crantée. Chez moi la rondelle crantée c’est cassé
@@vinci679 Est-ce la petite rondelle d'arbre ? Il repose sur l'arbre de transmission à l'intérieur du petit roulement pour éliminer le mouvement de l'arbre, c'est nécessaire.

Hi I have a zip 2 stroke with a de restricted pm360 pipe I am running a 19 or 17.5 carb with stock air box and the 70 kit featured in this video what are the best jets got this
I already have yellow clutch spring
Brand new variator malossie with 7.5 rollers
Just need to know the best jet to run and do I change pilot
And what are thefe best air screw turns and idle turns
Hello Jr Vlogs, thanks for comment.
You can try slightly lighter rollers. 7g.
The air mix screw should be 3/4 - 1 turn out. Do not adjust this in an attempt to tune the carby, this is standard for 50cc or 70cc.
The main jet is 88 for 2 week period, skip the video to 52:00 for a run down.
After 2 weeks we followed up with a systems check and retune, we finished the carby with an 85 main JET, Needle is an A22 Middle notch. We did not change the pilot jet. Your scooter will need to be tuned for the parts you fitted. Do not accept what we used as the final word, tune it as your engine requires👍
hello Did the ring gap need to be bridged?
0.1 mm per 25mm of bore.
Will a 70 kit blow my 50cc moped up because it's a few years old an if so what do I need to do to stop it
If the cylinder kit is fitted and TUNED correctly, you will have years of good riding. On the other hand if not done properly you will be crying on your motionless scooter.
@@wg11112 Where are you located? Most shops that sell new Scooter will have a workshop that does repairs and service, find one close and ask them..
Which jets do you recommend on piaggio zip 2t, with a tuned exhacust, and a polini clutch, and all the limitations is out?! and my carburetor is a 17.5 mm...
Buy me a coffee and I'll help you out as much as I can.. See home page for the link.
I currently have a yasuni r exhaust, malossi front clutch, polini back clutch, malossi cdi, and my carb is tuned. I want to upgrade to a 70cc malossi sport block but i need to know if im gonna need a new racing crank to go with the malossi 70sport block
It depends on what model scooter you have, but generally not unless you install a racing cylinder kit. If yours is a Piaggio engine like this, the factory crank is very strong.
Hello, can you tell me the malosi rollers you are using and what grams they are.
6.5.
@@scooterstreetau thank you👍🛵🏍
