"A whole new world!" Yeah, I remember that song from Aladdin, NOT the Little Mermaid, but right now I give zero f's about that. What I DO care about is that this is the most comprehensive, in depth video on how to install these performance parts. I watched this video roughly 10 times and it was the most valuable resource I could have ever found. Thanks to all of you at Scooterwest. You're doing the big work and it is much appreciated.

[@donnyleong5298]

2005 lx 50 owner from Canada. Pretty sure it's a two valve four stroke, 25 490 km. Got the Variator kit, head, and jets. Other than my only local shop charging me an arm and a leg to install the stuff, my scooter rocks now. So much better I can't even say enough good stuff. Get this for sure if you are over 150lbs, trust me, it makes the scooter so much more fun.

[@twennyfree]

Best vids i have found so far really in depth and you explain everything clearly. Keep them coming dudes

[@VespaMotorsport]

Thanks for tuning in!

[@mikeh4312]

This tutorial is great. I followed it and installed all three items described in the video on my 2008 LX50 4T 2 valve. With a good helper this is a fun project with fantastic results. The only real hiccup was on the removal of the forward spring under the footrest but I found that a large tack puller screwdriver was a big help and a quick fix. The only other problem area was breaking the bolts on both the variator and the clutch. It took about 6 hours of work for this beginner. THX VespaMotorsport.

[@VespaMotorsport]

Great to hear you tackled it on your own. Glad to help!

[@YamahaRiderMT09]

Hi im from Romania i learn it alot from your videos i love it now i know how to tune my engine on gilera runner 125 cc i love that engine !! Thank you guys :)

[@larrykeesee1442]

U TWO DID A GREAT JOB...I USE LUCAS BREAK IN OIL TO LUBRICATE THE CYLINDER..RETIRED LARRY IN INDIANAPOLIS...

[@slick41]

great videos by scooter professionals

[@chunkeeone8408]

Very informative!

[@canyonhaverfield2201]

had my face glued to the screen.. you two,Steve and Robot deserve an Oscar ! Amazingly detailed accurate flowing instructional.. way off the board well done ! Now I'm wishing S.D. was a lot closer to Mtry. then it is ! Darn ! Just rode my own '50'LX.. first time, up a good mountain climb.. hilariously gutless but still fun, so fun ! I'll be thinking 'bout this upgrade

[@alyaawaliyah]

great video

[@SeanJawn]

Just picked up a barn find lx 50 last night I’ll be ordering some parts from you guys for sure. Great video

[@VespaMotorsport]

Awesome, good luck!

[@SeanJawn]

With the 80cc malossi kit on my 2008 lx 50 will I need to buy a new jet as well? If so what size ? Thanks in advance

[@SanderCurtis]

Would have been great to see a video of the scooter performance before and after.

[@MrBerenguer67]

Thks four your excellent video I have a Vespa Lx 50 my carburetor drope a little petrol from the bolw if I remove the carburetor to change the tray is not out of tune Thks mate

[@Diedonacagedworld]

thanks this helped.!

[@stevenmullins3496]

Great video how about showing a video upgrading a 50cc Honda metropolitan scooter!

[@armanusa986]

I like to see improvement of this upgrade as riding on flat rd and up hill if possible. Thank you

[@brianheir]

Robot is a CVT rock star! I'm still just a bit intimidated by this one, I'll bring my bv350 to the man for now.

[@martinst-pierre8074]

hi guys ! nice vid!! could you tell me the part numbers of the shim pad for the 4 valvesÉ do they come in kit? thanks

[@nikitzo]

Hi, I have Piaggio Zip 4 stroke air cooled with 2 valves (the engine is the same HiPer 4). I'm planing to do the same upgrade with similar parts. Just have a question. Do I need to change somethin i the electronic of my scooter? Thank you for the beautiful videos.

[@rallyscoot]

What do you win on from a 2valve head to a 4 valve head? How are the engine characteristics then / how do the 4valve respond to a 2valve head?

[@nikitzo]

One more question. What are the part numbers of Malossi Multivar kit and the belt. I wach the video so many times but I didn't hear.

[@thumbs97]

I want to install this kit to but here ij europe we use Newton meters and not foot pound can you tell me what the prescribed torque settings are in NM for the cylinder studs? And camshaft screw and the 2 side allan screws?

[@Wasophangen]

Wil a malossi 4v cam on a 50cc work good ?

[@fintonmainz7845]

Is there much difference between doing this on a 2 versus 4 stroke?

[@zka75]

My starter motor or battery was weak to turn. What can i do? The connections are clean all, the battery is a new Yuasa 9Ah

[@chunkeeone8408]

I have a 2017 Sym/Lance Havana Classic 50cc and I was wondering what you might suggest to overhaul/supe up its hardware a bit? I like it a lot but it just needs more power. I am also having a slight issue with it as well; It seems to want to go dead a little if I rev it too high before it is warmed up enough. Is that normal?

[@KennyStyles]

What weight do you recommend for a 210cc Malossi Vespa GTS Super ie - Front clutch?

[@abdelhamidrihani8100]

Can i switch from the lx 50 4t 2V to 4V without replacing the hole engine ? and what will the gain be of a 4v over 2v ? Thank you

[@stuartpritchard2502]

So is this the same 4 stroke engine that's on the et4 50 cc?

[@imacmill]

I had a Malossi 80cc kit and variator kit 'professionally' installed in a nearly-new 2015 Primavera 50cc 4V 4T, and in addition to being ridiculously loud, it will only reach about 65 kph on the flats (40mph). The place that did it says there's nothing wrong with it, and that's the way it should be. That's gotta be BS, right? (Note that I did not have the cam kit installed (nobody recommended it))

[@jonydelacruz5148]

How can i get more ACELLERATION?

[@vracan]

DO all these upgrades also apply to a 2015 vespa primavera 50cc 4T? Are they all worth it to be done on this particular vespa?

[@skullgaffer1]

Thanks for this video ... I have a 2012 piagio fly 50 4v and need this kit desperately can it be ordered from your site also need both jets for carburetor

[@armanusa986]

I have same one , wonder why they didn't answer your question?

[@BrownSugarSonGaming]

do you need a new cabrator, excaust? sorry for my bad english

[@WertlipGamingTeam]

Pls do a 70cc upgrade video for the 2-stroke S, if you guys have 2-strokes in the US and A :)

[@Gismo3333]

Pretty sure it's just a change of cylinder on a 2-stroke engine. But you maybe mean 2 valves version?

[@davespooney8472]

Good work on the scoot. I'm shocked how needlessly complicated a modern 50cc Vespa 4t is. Same job on an older 2t Vespa - 1hr with engine in situ. I mean how much do these Vespas contribute to air quality? Surely the extra energy needed to manufacture a modern 4t outweighs what actually comes out of the exhaust pipe.

[@fintonmainz7845]

I know this comment is 6 years old but is it really that much easer on a 2t? I'm an idiot when it comes to mechanics so I'm going to have to pay someone to fit a malosi 70cc kit to my 50cc 2 stroke. Its so hard finding someone to do it.

[@corradopalmerini4076]

I see You got Wurth Bins Awesone stuff German n European OEM FASTENERS. I worked for them territory Manhattan n Bronx NY in the late 80s n early90s to my own Company in North NJ

[@bigrob497]

so theres no need for an exhust upgrade ?? and i have an et2 50cc what variator kit should i buy for that type of scooter and whats reed valve ??

[@abefrohman1759]

Steve and Robot were a good team. Too bad Steve's gone.

[@thechameleon77]

Hello. I was thinking of putting in the cylinder kit and multivator. Do i need to change the cam shaft as well or is it optional? Thanks

[@rubenvespa8898]

thechameleon77 it is optional but without the cam you will not get as much of a advantage from the cylinder kit. There are also cheaper cams that you can install.

[@HookupCultureCommunity]

I have the same scooter!! Except it’s an ‘07 2-valve Will this variator kit affect other parts of the scooter? As in do damage in the long run?

[@robertogonzales7988]

You guys are the man Steve and robot I've been learning how to take care of my Vespa because of you guys thank you very much and she appreciates it too

[@allhecs]

Hi, how are you? Can you help me telling what extent is the key that I need to remove the nut from the rear rim of a lx 50 ? Thanks

[@safarijonas3490]

I know that mine took a 22mm socket tool and alot of strength because the bearing seals melted into the hub.

[@i4dat]

Do you know if there is a variator kit and cylinder kit for the Sprint 50 4T from Malossi?

[@ionutgur]

Hy david, i also have a sprint 50cc 4 stroke 4 valves and i am having trouble findig out whats the best to improve performance, on my scooter i can only do 50km/ h maximum ( I live in denmark so the maximum performance has been restricted mechanically ) what progress have u made so far ?

[@brandon5058]

ionut gur hey there. easy solution: put a malossi 70cc kit on it. remove the vario ring(they also did this in my country).

[@brandon5058]

david, the variokit mentioned in this video is also for 4t.

[@daanvangroningen6872]

Niet praten 020 70cc is 2t,

[@nicolo717]

Apgret the jet number Is thes ??

[@hemelskonijn]

Eya, After having driven my Vespa LX 50 4T (affectionately called Vespii the vespa) to pretty much any place in Europe and to Morocco over the past 10 years doing well over 200.000 km she now died of exhaustion and due to me having some financial setbacks i will have to do an engine swap myself if i want her to be revived from her coma. I am not the most technical person and liked your video's for the simplicity with which you present how to do maintenance they helped me a lot. The video you refer to in the beginning of this video seems to be really hard to find maybe you could link it in the video description section? I have a few questions though number one being what is the easiest way to find out if Vespii is a 4v or a 2v model? How hard is it to replace the engine with a 4v engine in case mine is 2v or vice versa and what will the gain be of a 4v over 2v? Mine is limited to 50km/h and engines that are affordable generally are limited to 25km/h it is my understanding that they are only limited with a variator ring and CDI but otherwise equal to the 50km/h version is this correct? and lastly in my experience the 50km/h version runs fine flat but does have some issues going up an alp and at times drops back to as little as 18km/h what would be the cheapest and relatively easy to comprehend way to help her maintain speed when going uphill? And before i forget will exchanging the CDI for a non limited version cause damage if i open the throttle full and continuously on a long distance trip? I hope i can find some answers to at least some of my questions and thanks in advance!

[@ChrisDorland]

+hemels konijn You have done 200.000 km on a 50 cc LX? Or did you make a type and you ment to say 20.000? Either way much respect for touring Europe on a 50 CC :-D

[@hemelskonijn]

+Chris Dorland thanks, and no it was not 200.000 km but 236.000 km granted the old engine was completely clapped out due to exhaustion. In my experience this is far above the life expectancy of one of these engines. I swapped out the engine a week or so after I left the comment above and did just shy of 18.000 km so far. I still have loss of power uphill and the speed near the peak of Alps and Pyrenees are still around 15km per hour but I got used to it and get to take my time to look at vistas that scroll by extremely slowly.

[@ChrisDorland]

Holy c...p, what a distances on a LX! How many rebuilds of the engine have you been doing? Have you been blogging somewhere about this trip? I love reading about long distance travel on motorbikes and I am very interested to read about your adventures.

[@hemelskonijn]

+Chris Dorland I am not much of a writer and with nowhere to go other then the next road towards the sun the sea or a mountain or whatever i fancied those days i felt it not noteworthy. Vespii has her own facebook page thing made by a girl that traveled with me from HollanId via London to the south of Spain and back to Holland via Andorra and Switzerland. facebook.com/vespii/?fref=ts As to rebuilds ... Nope none though i am not really that technical and have gotten help from strangers fixing up vespii while she was down trough language barriers and lack of extended technical knowledge i can never be sure as to what has been reworked but i do know people where so enthusiastic about me doing this that they have never charged more then 80 euro to get her going again with an average of 30 euro and always told me i just payed for (part of) the parts. Around the 90.000 mark a lot got replaced and she was worked on for 3 days just under the 160.00 mark in spain a mechanic worked on her for a long time and he replaced amongst others the secondary gearing and what i presume to be the piston or piston rings but this was communicated via drawings on a napkin with arrows and a lot of waving hands and facial expressions. I replaced the variator VRM and CDI myself twice in the life of said engine and of course did regular maintenance (except for valve adjustments).

[@complexi8692]

Did you already reach 300.000 ?

[@thechameleon77]

So I had the big bore, camshaft, and variator(all malossi), main jet(78) installed. When the mechanic was done top speed was 19mph. so he put back the stock variator back in. Now i get faster front end speed but my top end speed went from 39mph to 35mph. And when at a red light vibrates like crazy. Only thing that minimizes the vibrating is if i release the brakes. This happen to anyone else. Any suggestions? Thanks in advance.

[@JoeKickass324]

your mechanic must be bad, they didnt tune the carburetor idle speed or air mix screw

[@veager123]

hitting 75km/h all the time then the rev limiter kicks in. also have big bore, camshaft , porting and K&N and still running 72 jet at 3000 ft altitude.

[@johncapidecallu8076]

Hi robot, i have a 2005 vespa lx 50 4 stroke. The vespa sat unused for 3 years and now it's really hard to start when cold and when it starts runs really rich (i can smell the gasoline) but when hot it runs fine. I have changed the sparkplug (the old one had a lot of soot and i used original ngk cr8eb), oil, cleaned oil filter, cleaned air filter, battery (used oem yuasa) and put fresh gasoline; but it still has this problem. The only things i haven't looked at are the carburettor and the valve gap (that i think was never done). The scooter has 18k kilometers, received oil changes every 1000km, has good compression and doesn't make strange noises. Any suggestion on what it can be?

[@marvd135]

John Capidecallu choke working?

[@johncapidecallu8076]

It's fixed now, I replaced the cdi ignition that was faulty, cleaned the carburetor and replaced the auto choke which was also faulty.

[@BriGuyBBY]

Here's a naive question. I bought a 2009 Vespa LX 50 a week ago. How can I tell if its a 2T or 4T? I got no documentation with the scooter.

[@unknownguy1123]

BriGuyBBY On the 4 stroke check for an oil dipstick on the left side of the scooter and it's usually black on the left front of the kickstart. For the 2 stroke engine look for a cap under your seat that says oil.

[@babycornell49]

How do I know what kind of kick start lever to buy or fit for my 2002 zongshen metro 49cc moped( bought the moped used and it didn't have one)

[@MrRichard57000]

Melissa Cornell i think you have the gy6 engine but i ame not sure.

[@babycornell49]

+MrRichard57000 thanks for the info. that scooter of mine stolen and JUNKED . I got it back and no point to put any money to fixing it . since beinging of Aug I got a new 2011 sunny 50cc scooter and bit has a kick start on it

[@MrRichard57000]

have fun with your new bike,if you notice that your kickstarter is going lose wrench it tight it will slip over the axel and kill the splaines and check your oil every week or two weeks so you have understanding from the oil consumtion if there is any.maybe you can keep your old scooter for parts if it has the same engine.they stole a honda nx 250 from me and the police called me too pick it up,it has a damnedged ignition lock but they could not start it .thats what they do when your bike is unlocked,they push it around the corner and pick it up at there convinice .

[@street_fighter_mx5]

Please link to website

[@pbloglbrto]

can you guys do a video of the same upgrade for a GTS 300? would be awesome!

[@Gasrullen]

Standard weights are almost always a little heavy stock, i would recoment slightly lighter in the original variator if one can't afford the malossi, Guessing you guys sell them to.

[@Gasrullen]

+ The carb usually setupa little lean... to make it run cleaner and get more milage per gallon on paper.

[@street_fighter_mx5]

Where can I buy these parts?

[@gblan]

So I bring my 50cc Vespa in and want the cylinder, cam, variator upgrade shown here with all the replacement nuts, bolts, gaskets and belts what would the $$ be including labor? Ballpark.

[@VespaMotorsport]

+gblan Give us a call or send us an email and we can get you a proper estimate. 619-280-1718 [e-mail] Thanks!

[@gblan]

+Vespa Motorsport I don't own a Vespa (yet) and I live in Florida besides. I was just curious. Surely you know the average cost of this job. $1000, $1200, $1400?

[@VespaMotorsport]

+gblan We actually had this exact setup already in an estimate and it's only around the $700 mark including labor. Thanks for the inquiry!

[@jackieboy8]

+gblan in the Netherlands this upgrade would cost you €350 ~ €399 because those parts you need are really cheap (this is the price including Labor). If you know to do this yourself I would recommend buying them from eBay.

[@mikepelicas7642]

Vespa Motorsport do you have a parts magazine to order parts from and if so how could í receive one

[@Wasophangen]

I oil the paper gaskit so its easyer to remove

[@jackdonker1482]

Okay couple mistakes, First off all: don't place the white Malossi clutch spring thing. Second: you putted mutch too light weights in the Vario. In a Malossi vario goes 3Gram heavier weights in than in Original vario. So for 2V you put in 9.4 Gram for max performance. And the mainjet has to be around 82-86. But the camshaft is a must, and the 80cc also. After all of this with a Ducati yellow CDI unrestricted you'll go 84km/h with high windschield. (For 2V)

[@jenny-masterchef]

you guys make good videos but stil need to learn.5 gram is too light.With malossi multivar you shoud try 7.5- 8.4 gram.Otherwise that engine will blow up trust me.Mainjet 82,84.Change the CDI and That's it.Watch and learn how we do it in Europe. ;)

[@dnh3005]

Lol best updrage I did was a 80cc cilinder, race camshaft and the malossi vario. But still slow as fuck because it is 4stroke. It reaches 46mph if im lucky.

[@dokesz530]

bigger cyl and camshaft made for beter acceleration.u need to feel a different if not u did something wrong.

[@MotorheadRedo]

Good Video! Wish Vespa scooters were cheaper......I don't know how Vespa survives with all the cheap Chinese scooters flooding the market. I live in a small town and I've seen Chinese scooters here, but never a Vespa.

[@donaldlee6760]

Agreed, I ended up buying a used Vespa 250 GTV that was dropped and all scratched up on the side. It's now painted over in Rhino Liner (spray on rubberized truck bed liner) and looks more like a movie prop from Mad Max than a fine Italian scooter, which I think is pretty cool!
