- Welcome to Scooter Street! In this exciting build video, Brad takes you through the process of finding and rectifying previous owner scooter tuning mistakes and mishaps. If you have bought a scooter which has previously been modified this is a must watch.
Brad starts by showcasing a Piaggio Zip scooter that was previously tuned by an inexperienced owner. He points out the mismatched parts and the major problem of a seized piston due to improper tuning. But don't worry, Brad has a plan to turn this scooter into a prime candidate for a major upgrade.
He takes you through a detailed pre-assessment of the scooter and highlights the unusual modifications done by the previous owner. To enhance the scooter's performance, Brad recommends installing an MHR racing cylinder kit. He also suggests a range of chassis upgrades.
Throughout the video, Brad shares expert tips and tricks for proper installation and tuning. He emphasizes the importance of measuring the squish and explains how to correctly install the cylinder kit, avoiding common pitfalls like circlip mishaps. He also discusses the advantages and considerations of using pod filters versus air boxes, ensuring you make the right choice for your scooter.
But the tuning journey doesn't stop there. Brad dives into carb tuning, replacing faulty parts like the throttle cable and fuel lines, and fine-tuning the scooter's performance. He also addresses clutch issues and recommends the Polini G3 clutch for its adjustability and reliability.

Great video and yeah I can confirm that you definitely need that c clip in properly, cost me a brand new kit a couple years ago never made that mistake again😂
Ahh yes, we have all done that😂
guy fails to mention is that the clips are directional. If you lay them on a flat surface you should notice the legs bend away from the plane of the circle. The legs need to face so they bend away from the pin else they can be snapped off.
great video🙌🏾. I have the malossi cast iron 70cc on my Aprilia Srmt. It runs great, tops out at around 90kms. I May upgrade to a more powerful kit though. Probably an mhr rep
Thanks Kahlil. What is your current set up list?
Anything sport or below should use stock airbox
Anything mid race and above should use pod filter, I run a polini Corsa 70cc Piaggio LC ported with polini covered airfilter polini cp21mm
Good input, Thanks👍
Another great one, have you ever done a repair on the aluminium holding the front part of the main stand on the engine, got a hiper 2 im restoring but ever single fastener is rusted stuck😄 bike was pretty rusty too. But need ti save the engine!
We have seen this several times, You can fit some washers ether side of the aluminium holes of the engine but it really needs to be Al welded for a true repair.. Or fit a side stand and have a workshop stand for repair work.. Thanks for the long time support ML🎅
Hi, I've just subscribed to your channel I really like how detailed your posts are..
I have a 1999 aprilia habana 50cc that I want to improve performance, could you recommend some items to get me started. Thanks
Oh thank you for the SUB and your friendly comment😊.
I always recommend a performance pipe to start if running an original pipe, and then follow up with a cylinder kit and carby and so on.
Nice job Brad.👍
If you ever change a Euro 4 Piaggio to run a normal Dellorto carb without all the sensors and air injection, I would love to see how you go about it.
I think in the future it will be something people will do. A bit like the Aprilia ditech conversion when it breaks.
Keep the videos coming. 👌
Thanks and yes we have done this a with a few E4 models, run the standard carb with all of the sensors disconnected. It led us to trial the headless kit in an attempt to have the dash warnings and Temp sensors functioning. PF, you are a great supporter of our channel and we thank you for it.🎅
@@scooterstreetauhey bro need some advice please
Hi! Love your videos, assembling My mhr kit as i am typeinformasjon this😂
Just wondering, do you have ant tips for getting those C Clips inside of the piston? You make it look very easy, byr i am struggling a bit.
And also i have a 21 mm carburator and a full polini clutch and variator with 6.5g, going to run it with a stage 6 exhaust sinne the malossi mhr exhaust dont fit. Do you have any idea what size jet i should try out?
Thank you🙌. Fit the transmission side circlip into place before mounting the piston on the conrod. If you have a flat blade screwdriver of te small size, you can cut a small groove into the tip so it creates an area that the circlip will fit into. Use the screwdriver to gently press the circlip in to place. I hope this makes sense👍
For the jet if you are running a POD filter tart with a 110 main jet and move leaner as required, don't be impatient and try every jet size as you lean it off don't skip. engine must be warm..
Hey, do you need another crank for the malossi kit or its okay with stock
Yes that is best practise. Budget dictates the build.
I know it's hard know what to say on videos but.....Did I miss something or did you not set the ring gap?!
Every cylinder kit needs this or ring expansion causes it to seize or break! Or can.
Pre ignition - ignition too early for a few reasons.
Detonation - ignition becomes explosion ie burns faster than sound.
Too big carb or race pipe won't cause seizure if jetted right.
I used an mhr pipe and 21mm phbg on a tuned standard cylinder for ages......all of 11-12 bhp at 11000rpm!
Yes. If we filmed and showed everything we do our videos would be 12 hours long. Can you make up a short video showing how you do?
Bro I’m trying to tune a 21 malossi delly it came with 70 main 60 pilot and 45 I need advice
connect through the website. www.scooterstreet.com.au/
Do you by any chance have a picture of a 2 stroke oil tank on Piaggio zip 50 cc build year 2013, cuz i bought and it did have a the tank and i want to buy on, but dont know which on to buy.
Piaggio's are quite rare in Suriname.
Like your videos👍
Yes, check here for the Piaggio Zip Oil tank.

@@scooterstreetau Thanks!!!!
I appreciate your videos, subbed. Would you daily/street that kit? Or is it possible?
Thank you, much appreciated🙌. This setup was used and recommended for weekend blasting until the guy lost his licence.🙀
What carb or size do you recommend for that combination of cylinder kit?
@@ayomaggotz Minimum 19mm
Hi I’m about to order a 70cc cylinder for my sr 50 r 2020 and was wondering which one you would recommend. I’m not planning on changing the crank shaft or carb. I already have a cdi and the price of the cylinder does not really matter, just trying to push as much power as possible with stock crank and still be kinda reliable. I was thinking about something like a stage 6 race/ sport pro, mhr rep
Either of the ones you have mentioned are very good. The crankshaft and bearing set that you have must be in good condition before considering an upgrade. So if this is the case go for it.👌
@@scooterstreetau is there something I have to know before installing which is special for my model (sr50 r euro4) or is it just like any other bike
@@theo2522 There is a temp sensor attached to the head, if you use the Malossi kit you must purchase and fit this Malossi part 1518132. Now the sensor will function. Other than the sensor all the same as other 2 stroke scoots.
hello at minute 7:50 down there on the crankcase where the connecting rod sits, I have some scratches, 3 scratches on the whole side, but there are straight scratches on the crankcase, which means none of them are flesh, is there a problem? I hope I explained myself well enough
Try to find what is the cause of the scratches...
hey, can you do a video on how to change the locks on a zip, the ignition lock and seatcover lock?
We will be having a break from videos for a while as Brad is moving to a new job and I have very little time to do the videos will all that goes on in the shop, we will try for this video when time comes free.
Dear Scooter Street, Very useful video thank you. May I ask for advice about my setup.
Aerox Minarelli horizontal engine. 70cc Malossi MHR replica,
TPR performance crankshaft
Yasuni R exhaust derestricted.
Vforce reed valves
standard airbox without snorkel and Intake manifold.
Just bought Delorto PHBG DC 21mm and I have no clue on Jetting it. Can you please Give me your opinion on what main jet I should start with and work my way down?
Thank you.. Start with 94 jet, you may end up in the range of 82 - 90 or thereabouts. You should consider changing the needle too.
kind regards. thanks for your videos. I have purchased a 70cc air cooled Malossi Sport cylinder. I have a Tecnigas Triops exhaust for 70cc and the exhaust outlet hole of the cylinder is smaller than that of the exhaust by about three millimeters. What I can do I will thank you very much for your help.
Hi Carl, THanks for watching and commenting👍What do you want to do? Do you want the same diameter? you can machine the cylinder to match at the two points.
Hellou i have a vespa primavera 2t and i sort the site from the carburator and i put a 60 jiggler . Now its runs very fine all to 65 km h . Do you now if i have to modify something to the oil pump ? Thankyou
The pump and system should be working and well maintained, so check it and replace the worn parts..
can i use mhr rep with my stock piaggio zip crank? Only has 800 european miles on it.
Yes you can, but the Small end bearing must be checked every 3000kms as they wear and also can wear the small end of the conrod. Recommended to use upgraded crank.
Hello,
Im about to purchase a Piaggio nrg LC. Do you think its a suitable scooter to try something like this? What do you suggest checking before starting? Thank you in advance.
Yes absolutely👍. Make sure all systems and engine devices are working and in good order, bring the engine and safety up to speed first.
How can crank hold it bro??
The crank is upgraded...?
Very great and detailed video, been waiting for it some time now! As a question, why did the customer opt for Air Cooled instead of getting the zip SP2 front and Liquid Cooled? Is it because of personal preference, to save money?
I'm also interested in that, because I have an AC machine so I want to know is it worth changing to LC
@@oliverbabic7982 Thats a great question. He didn't want to spend the money is the short answer. One of our team has done an 'SP' liquid cooling conversion to an air cooled Zip quite successfully previously. We even have a parts list here to do the single swing arm SP front end conversion too, just waiting on a candidate to step forward! If and when we do one, we'll definitely film it!
@@oliverbabic7982 It is, the difference is dramatic. There are a couple things you have to work around - however the AC chassis still even has the radiator mounts, so the conversion can be done easily using factory parts, where there aren't better aftermarket ones available. The big key we've found in the past is if you go for an electric water pump, make sure you keep the thermostat in the head to slow the flow (Unfortunately the AC engine casing doesn't support the bearings for the factory water pump). Electric pumps often flow so quickly that the coolant doesn't spend enough time in the radiator to adequately cool down. I suspect even Malossi have had this issue on the C-One, as they have developed a special liquid pump controller which adjusts the flow rate of their electric pump according to heat sensors and some manual controls. If you're lucky enough to own a genuine Zip SP, the factory water pump doesn't have any of these issues.
Hi Brad I’m struggling with my gilera stalker 2T I have installed the 70cc malossi kit the Leo vince TT exhaust 5.7G rollers changed the reeds and I have the red sponge with snorkel out. My main issue is with jetting I just can’t get it right I started on an 82 the bike spluttered and didn’t want to go very well so I went to an 80 and it was still running too rich and fouling up the plug with black oily spuge same with the exhaust tip. So I’m now on 72 and it’s still not right. Do you have any idea on what jet size I should try next because I just want to get it right before I damage my scooter again I think it could possibly be over oiling is there any adjustments to the oil pump I can make? Any help would be much appreciated cheers!
Was the scooter running normally before changing these parts?
It sounds like you have an issue there external to the parts you have fitted. It should tune within the jetting you have tried..
I have a piaggio zip with a malossi 70 cc sport kit and want to delete/disconnect the oil pump to run pre-mix. What is the best way to do this?
Remove the oil pump belt. Shorten or remover the oil hoses, or remove the pump completely.
@@scooterstreetau Thank you very much
I’m getting the MHR KIT FOR MY AEROX will I also need to change crack and carb aswell
Yes It will give a lot more power if you do the Crank and the Carby🚀
can this malossi mhr cylinder run well with standard crankshaft if one's machine is relatively new
Yes if the condition and age is low for the crank it can be done. We encourage an upgrade on the bottom end as soon as you can, so save up and do it all at one time.
why do my nrg 70cc started to stuttering and run better when the moped wants
Hello , I need more info.
what jet do i get on my piaggio nrg 70cc stage 6clutch malossi multivar varuo gianelli extra
Start at 95 and move down from there. Start at 120 for POD filter.
Hi guys, what jet do you usually put on a mhr replica whit arrow extreme and phbg 19?
At a guess I would say you'll probably end up with somewhere around an 85 - 90 jet with that carb. It depends highly on what exhaust you have on the bike. A basic exhaust like a Leo Vince TT will be on the smaller end, and conversely a more performance orientated exhaust like a Yasuni R will be on the upper end.
Is there any tuning parts for a malaguti f12r 2010 ac (i didnt find any)
There are many parts, look into the Minarelli Yamaha AC engine. All of the Suppliers (Malossi - Polini) I checked had parts for your scooter.
What gear up kit and carb is on this scooter? Thanks :)
A few months later we fitted a 21mm carb and the Malossi secondary gear kit.
0.8 is not a squish on a 70cc. You will increase detonation risk & lower efficiency. I would recommend reading some basics on 2T tuning like the tuners handbook by Gordon Jennings or anything by A. Graham Bell.
We follow the engineers instructions from Malossi when setting up this kit? I would recommend reading the Cat in the Hat😹🎩 Instructions from Malossi: eamalossistore.blob.core.windows.net/files/montaggio/pdm/73%208455.pdf
.8 is actually quite safe for this engine, they run down to .6 with no issues whatsoever. 0.6mm squish with the right head volume on one of these they run sweet and crisp :)
I have Yamaha vino 1992 50C c's wish kit can I use bigboard
It can be done, you will have to source the parts from Japanese suppliers..
How tp get the top speed higher on a piaggio sfera 50 cc
Watch some of our and other tuning videos. You need to improve key parts of the engine. Exhaust, Transmission, fuel system.
how much power and rpm
approx. 13HP
Was anyone scared for the reed block/ carb bolt was going to fall into the crank housing (19:00)
No not scared, We have dropped certain parts before and to retrieve them you can use a great tool which has a flexi wire or telescopic arm with magnet at the end (magnetic pick up tool). You must appreciate how difficult it can be to hold the camera and remove parts with one hand. Thanks for watching the whole video👍
hello, I have a sr motard of 2020 and I would like to know what you think of this elaboration
Top racing gold line
Yasuni c16
Multivar 2000, fly clutch, malossi catch bell and malossi kevlar belt
19 dell’orto
Malossi e13
Crankshaft top tpr b80 sp12
Malossi vl13
Malossi digitronic
Sounds good, many nice parts in the list. If it performs well and you are happy with the ride, then Great setup👍
Squish?
0.55 - 0.6mm for racing, I would reccommend closer to 0.7mm for a street scooter.

How dumb of an idea is to slap on a 70cc kit with the stock crank?
Not a Dumb idea at all! Give it a go and when you are ready upgrade the crank. If the crank or main bearings are showing excessive wear then change them before fitting the 70kit. Otherwise go for it✌
