Thank you very much, I really apriciate the fact that you guys took the effort. Today i fitted the 187cc malossi on my Piaggio Zip 125 and i'm sure i couldnt do it without your video first time changing a 4 stroke cylinder. Much love from the netherlands

[@scooterpartscoscooterparts6430]

Excellent Video. Steve does a great job of explaining the part and how it works.

[@surasak4499]

I like. I live in Thailand. I also have a Vespa Sprint 150. See how to fix it. Gained a lot of knowledge Thank you for watching and studying about Vespa. I love Vespa.

[@vespa7265]

Brilliant video. Please hurry up with the dyno testing results. If good, I can get one to fit to my 150 3v GTS.

[@Yahoo886]

Thank you Robot... you are awesome👏 😎 . I appreciate you guys so much

[@VespaMotorsport]

Our pleasure!

[@vespa7265]

Come on guys. I bought the kit off you in the hope you would do the dyno testing as stated at the end of your install video. Im still waiting! 2 plus years later!

[@chase14000]

have you installed it? how is it?

[@gumonthepants]

Here we are, another two years later and no reply from him either. Conspiracy.@@chase14000

[@RolandLiMY]

Very nice detailed guideline!!! GJ

[@andreacoiro3978]

Hi there, I've a primavera 50cc and I would like to try to do this same job myself. Are the bolt the same size on the 50cc?

[@namcojr]

I just wish the Portuguese Vespa representative was like you guys. Here to fit such kits or to get official support on them is nearly impossible.

[@richarddegen6184]

getting ready to install this kit in my 2016 Sprint which already has the multivar malossi variator kit, hi flow airfilter and acropovic exhaust pipe installed

[@richarddegen6184]

If this setup is satisfactory, possibly overdrive gear set will be next

[@richarddegen6184]

installed Bitubo suspension and next size larger Pirelli Diablo rosso tires also

Hello Dear all thanks for all these videos I have one question is it necessary to upgrade with a cooling system the motor , now temperature is going up so fast thank you again best regards from Colombia

[@richardsteele6776]

Magic Robot ! What performance change could be expected with this cylinder kit ? I know the top speed of the 150cc so the 183cc must get at least 75 mph. Sorry I am so curious.

[@efendi171]

Very helpful video, unfortunately, there is a part blacked out (from 19:50 to 26:30). Any reasons for that? Is there anything to consider, while disconecting the fuleline, connectors and dismantling the throttle body? The factory manual says, that it is necesarry, to calibrate the self-adjusting parameters, after disconecting the throttle position sensor. Any comments about that? Thanks for your effort, of making these tutorials.

[@richarddegen6184]

noticed that...not good

[@ronaldsanpedro1976]

Whats the weight of the malossi piston vs stock pistons? Im very interested to get one but im worried if the bigger piston is alot heavier vs stock, as it will introduce more engine vibration since the crankshaft is balance on the weight of the stock piston.

[@roverroko306]

So Robot, those wires you are connecting with a posy tap, if you didn’t do it that way. How do you connect with white plastic connectors which come pre installed on the wire loom already, where are they supposed to snap in to?

[@nantawatkongcharoen4719]

Nice job.I love it.

[@severinonatar8797]

What is the partnumber for the forcemaster injection module. I accedently order the wrong cilinderkit and i want to buy the forcemaster separtly

[@emilianomanfrin5043]

You guys have a manual or video for the same thing but for a Vespa Primavera 50cc 4t year 2018? Thanks

[@vespa7265]

I bought the kit but performance is pretty much on par with the standard 150. I'm guessing there are several factors for this. 1/ not broken in yet and 2/ needs fine tuning so come on scooter west where's the dyno video you've been promising???

[@tranminh1316]

Andrew Pugh it's been 2 years since the video. How's your kit?

[@richarddegen6184]

20% displacement increase.....you should notice a significant performance boost

[@Ukrainianification]

Not enough to spend the money

[@grazryan]

Hi scooterwest, How is the gas consumption after the upgrade? Do I also need to upgrade to overdrive kit?

[@spyder2001]

Thanks. Is the process similar / the same on a 125cc ET4?

[@roverroko306]

What’s going on with that long gap when the screen goes blank for about 10min, maybe longer? That’s just so unlike you Robot man, did you forget to edit .

[@zharifrif4960]

Hi robot.. can you show how to connect yellow wire from malossi force master if I used vespa primavera 150 3v model.

[@GYccUsefultips]

is there any advantage clocking the oil ring gaps on the upper side(Intake side)?

[@Ozoe]

I'm installing the Malossi Cylinder kit, as well as the variator, do I also need to replace the sonda lambda or just with the malossi cylinder kit the scooter will run faster in general, i dont want to suffer the speed limitation of the sonda lamda, help please, great channel, I love it

[@vespa7265]

I think I'm going to blow my engine soon if I don't see this dyno test!!

[@bozcaret]

what about the blue wire? mine has no blue but its red wire

[@robertrehrig8416]

Does this kit work on the liberty 150? And how much $$$?

[@steveb936]

what engine codes are these Vespa's

[@vdwijgertrobbin]

Do you ever sell gilera runner 200 in the usa or do maintenence on them.

[@keiko909]

The runner uses the same engine as this Vespa. It's the 4 stroke leader engine

[@Mikolaj_u]

Good video! What are the new figures for 182cc? Specifically, acceleration 0-30mph, 0-50mph and top speed? I'm thinking about buying this kit but need to know if it;s worth it. Robot once wrote that lighter rollers on 150 would outperform 150 with 190 kit. So, what rollers would you recommend as a replacement for stock rollers on Primavera 125?

[@VespaMotorsport]

+Mikolaj1406 We recommend the Malossi 12.5g weights on a stock Primavera or Sprint. We are planning on doing another video with this scooter being Dyno tested, it should answer all your questions and more!

[@Mikolaj_u]

Thanks!

[@jasonsanchez4333]

Robot kindly clarify. You mean you just replaced the rollers? Stock variator?

[@jimbolecat]

@@VespaMotorsport Hi there, what weights would you recommend for a stock piaggio fly 125 ( 2 valve 2006)

[@richarddegen6184]

@@jasonsanchez4333 I did a malossi Multivar, aprapovik exhaust, 183 big bore kit, malossi hiflo air filter element and 15.8gr rollers....hauls ass 20% dyno increase full rpm range

Hi! Im wondering, is it okey for vespa sprint with malossi kit 183cc run 80-100km/h for long run or doing some long high way touring with just water cooling system? Im using vespa sprint but sometimes it haunt me of overheating my engine :( any recommendations? Thank you! 😃✌️

[@oliviervandervaart3366]

I sometimes run it on the highway for over 40 minutes on full throttle ( Vespa primavera 183cc full malossi overdrive etc.. onnly top speed is 110km/h ......

[@MrElreng]

Hello, Is it possible to use NGK sparkplug CR8EIX after installation Malossi cylinder 182 cc and how effective is it?

[@richarddegen6184]

CR8EIB-10 irridium....defnately worth installing

[@itsmylife4fucksake]

Can you tell me for medley 125 is it possible to do this kinda thing ??? I see that it is on malossi site. But i dont know anyone who did it ? Iget engine 125cc 2019 year built. As i see both for 150 and 125 is increases to 180ish cc. And will engine work good with variator and exhoust from malossi. Can it survive that. ???

[@VespaMotorsport]

We do not have the Medley here in the states so we can’t comment on it specifically but it should have the same motor as the Primavera. We also only have the 150cc here so can’t really comment on the 125. All the performance items will put more wear and tear on your engine, but if installed correctly, and you keep up with all the scheduled maintenance, you should be fine. We haven’t had too many issues with any of the Malossi stuff. Thanks for watching!

[@itsmylife4fucksake]

Also can you tell me if it comes eith malossi force master 2 ??? Together or you need to buy separate

[@VespaMotorsport]

Yes the kit comes with the fuel controller: www.scooterwest.com/malossi-183cc-cylinder-kit-w-ecu-mapper-primavera-sprint-m3116550.html

Will this cylinder kit work with the i get primavera?

[@richarddegen6184]

there is a kit for the preimevera 3 valve

[@andrewsmyth8837]

what is it like up hill with this on. and does a new cc mean much higher fuel consumption?
