My first scooter was a gilera runner 125 with a 172 conversion . This is going way back probably 15 years ago now ! It was highly sought after in london , after multiple attempted thefts from garden i eventually sold it for £3k and brought a car . Ive had mutliple ducatis , and ive got to say bang for buck , that gilera was one of the most fun bikes of them all !
I will modify my 2016 sr 50 with these parts, 70cc replica, phvb, vl13 mhr, stock airbox red sponge, yasuni r, what main jet size to start tuning the carb? cold here in Europe, thats a factor also 😬
@@scooterstreetau A question about intake manifold!! Got the malossi 360 manifold that fits the phvb, Malossi code 2014519, but the angle of the carb will not work, almost standing on the end?? Can i buy one from you that levels the carb and also makes it possible to get close enough to connect to the stock airbox? or if not where do i find one? And how do you connect the phvb and stock airbox?
10:00 i see a lot destroyed Hiper2 OEM cranks and bearings even on full stock scooters(Runner, SR, NRG), crank literally snap on variator side, behind oil/water pump belt "sprocket", also OEM KBC Korea crank bearings are crap, on my Runner they had "half meter" gap, new stock scooter with only 4500km, only good bearings for Hiper2 crank is NTN Japan(not Taiwan), and Koyo Japan, mine NTN has 62 000km and still runnin', engine is 50cc, but still impressive i think One good hack for airbox, try to find old Piaggio big "triangle" airbox, it's better than this SR(or small Runner and NRG) stock airbox, i have it on Dellorto 17.5 phva, also you can use it with 19 and 21mm carbs, but for bigger carbs you must bore the inlet hole
Can you make a max out 4stroke 50cc or take the most ugly 50cc or a Cross/dirt like or before and after video maintenance, to show that even a 50cc needs maintenance (i hop it is the right word, Kundendienst in German). Or options for better air cooling or how much improvement brings a custom ignition timing curve (with dyno and so) or what Parts you can use from a newer generation or wpc treatment for a 2Stroke or to make it less fuel consumption or to get a better oil ration like 50:1 to maybe 100:1 or higher and blow your engine (colder plugs?!?) or can i use a stepper motor for throttle (throttle by wire, if it's possible you maybe have a Crouse control) or makes it a difference to cut the restrictior shorter (police) or change to a bigger restrictior and shot them. That's all i have in mind
Hey Alexander, thanks for comment. If we get 1 come through we will do the video. The main reason is that the 50cc 4T is so slow and very expensive to modify for a reasonable advantage.
Is a 22phvb too big for a polini sport kit one just came up for sale on my fb and this guy is selling it for a steal should i get it and do i need a different intake manifold because im still running the factory 17.5 carb?
Hello, ive wanted to ask if it save for me to install a 70cc on my high milage crank, my scooter has 36k km on it and im scared it almost at it end, do i need to install a new one or i should be ok
not really popular in australia, but mid-race parts are the same for Peugeot (like the MHR Replica cylinder, yasuni r, etc.). But, for high-end parts, nothing is really available new, since most of the stuff is discontinued.
Hi so I have an SR50 Euro4 and Im wondering will the bike run good with the mhr replica, a 21mm carb, yasuni r and malossi 13/48 secondary gears (I heard the gears are shorter on the E4 models and my bike currently stops at 75 km/h)
@Vel_178 Yes, the Black Throphy for me is the most reliable kit as a daily. Have it on my Speedfight 3 AC, 4000km with a piston ring change at 2k to get back the compression and it runs like new!
@scooterstreetau Nooooooo😭‼️🤣🤣🤣 Thanks and what are a scooter with good front Brakes? A friend of mine have a Hercules Splinter (Peugeot speedage) the front Brake is awesome, but rear brake is worse than Piaggio.
I always comment positively on your videos and this one is Stella .....What a fantastic video thankyou
Hi Charlie, we love positivity and you have heaps of it, thanks for your wonderful support🙌
hello why do you always put malossi cylinders? why not stage6?
Stage 6 is so expensive to ship to Australia, if we buy a $200 Cylinder the shipping from Stage 6 cost $160
The best video I've ever seen. The advice can be used for various 2 stroke scooters in general. Simply great 👍 👌
@overlandworld2253 Thank you so very much, appreciate the wrap🙌
Thank you so much Brad.. As I have just bought one this week timing could not be better... Awesome work..
Hi Nick, What year? COngrats, you have just purchased one of the greatest scooters🎉

Thanks and we really look forward to it💥 I never received your email, contact us for your next project🤙

Great information Brad. 👍
Thanks Paul, how are your machines going?
@scooterstreetau one aerox is going good. The other is still a project. You know how it goes.
Drives the wife nuts. 🤣

One good hack for airbox, try to find old Piaggio big "triangle" airbox, it's better than this SR(or small Runner and NRG) stock airbox, i have it on Dellorto 17.5 phva, also you can use it with 19 and 21mm carbs, but for bigger carbs you must bore the inlet hole
I use SKF bearings, they did 20.000 so far
Can you do a video for 50cc 2 stroke how to set corectly the floath boath on carburator??
THat is a good idea, most are set from factory and some can be adjusted by heating the plastic or bending the metal support in favour.
I have a aprilia sr50r 2020 and one exhaust stud bolt snapped in half when I was removing my exhaust… What Should I do?
You will need to drill and tap it out to remove. watch a video on how to remove a broken bolt.
Cilinder gasket 0,50mm for model with high compression and 0,75 mm for base model? THX!!
TRUE, you certainly know your scooter engines.

If the price is right I think a good buy, are all the parts in tact? Yes I beleive the intake is larger and we have available.
Hello, ive wanted to ask if it save for me to install a 70cc on my high milage crank, my scooter has 36k km on it and im scared it almost at it end, do i need to install a new one or i should be ok
Good idea to upgrade crank and bearings, but if you want just put the kit on. It totaly depends on so many factors.
@@scooterstreetau i was thinking about to do it on my own, do you suggest any cranks i should use?
@a_person7036 Malossi.
22mm Carburator malossi
Malossi MHR 70cc replica 318466
Yasuni R
Malossi Overrange 6118835
Gears HTQ Z 14\39
Stock ignition
Stock clutch (Red springs)
Stock CDI
Stock cranckdhaft
What are your thoughts?
(Ca81m) 2020
Would recommend new crankshaft, yasuni r is not optimal for MHR cilinder..
Do you get enough RPM from this setup on those gears?
Carb and exhaust dont match. With Yasuni R a 17.5mm is enough. Want to stick with your 22mm? Than get a C16.
Hello just started watching your channel can you do with Speedfight 1 and 2?
not really popular in australia, but mid-race parts are the same for Peugeot (like the MHR Replica cylinder, yasuni r, etc.). But, for high-end parts, nothing is really available new, since most of the stuff is discontinued.
Yes speedy parts are getting harder to get now unless you just want a sport level build.
Hi so I have an SR50 Euro4 and Im wondering will the bike run good with the mhr replica, a 21mm carb, yasuni r and malossi 13/48 secondary gears (I heard the gears are shorter on the E4 models and my bike currently stops at 75 km/h)
What model name SR50?
@@scooterstreetau Its the SR50R 2018 CA81M Piaggio engine
@@faw2562 Yes it will be a fine scooter with these parts. Consider upgrading the transmission and CDI/ECU.
@ I plan on upgrading the transmission in the future. I already have the Malossi CDI
@ Also would I need to remove the oil pump and pre-mix the oil or can it handle the 21mm ?
hey i wanted to ask malossi mhr replica 50cc or 70cc?
70cc
Yes, @bb_adrians4672 is correct 70.
@Vel_178 Yes, the Black Throphy for me is the most reliable kit as a daily. Have it on my Speedfight 3 AC, 4000km with a piston ring change at 2k to get back the compression and it runs like new!
@@scooterstreetau can you pair a 47mm cylinder with a 47.6 piston if you port the cylinder
@@AngelovMihail-h3j The cylinder must have allowance for the piston size.
About a Piaggio Sfera nsl 50 '94
That what i have and a Video about it👍👍👍😁😁😁to tune or what is good! Don't forget Drummbrakes, no Disk😎
We never had this model in Australia, we had the 125cc.

The best mods are to buy a 172cc skipper engine and engine swap it.
They are fun, but those engines are getting expensive
@ its worth the extra €150. U’ll have a beast. Im never selling mine
@@Boogyman91111 where do you find a good skipper engine for 150?
@@landmonkey22 nowhere. I precalculated the tuning parts u’d usually have to buy which is around €600 (exhaust, bigger carb, cilinder etc)
