Excellent tutorial guys! Have been riding my scooter for ages without realizing what was going on in the transmission system! Thank you from Italy 👍🙏

Thank you Fede, Gday from Australia🦘🦘

Great video - like that variator marker tip for belt / roller tuning. Good stuff.

Thanks and glad you like the pen tip👍heaps of tips in the audio of all our videos.

Thanks bro, ur video is very knowledgeable, even i can't understand your language as very well but also after that i watched ur video and understand with the helps of hand movements thanks keep it up... 👌

Thank you my man, great appreciation🙌

Are you able to do a sports (chamber) exhaust tutorial for the zip? As asides from transmission/varistor mods, chucking a sports exhaust on would be the most popular mod. Would be good to see that + re-jetting the zip for it

[@scooterstreetau]

Yes we will do that, we are starting a Piaggio Zip Series as we speak. So stay tuned it will hit the tube this Saturday.

[@jacobperei9191]

I really like your video, it was so helpful and clear to understand! I changed my OEM rollers with the help of your video! Are the OEM Piaggio rollers supposed to rattle a little bit? Not on idle but when I rev and accelerate. It’s a bit annoying. Thanks again for the helpful video! Subscribed 😎

[@scooterstreetau]

Hello, Glad it helped and well done👌 The rollers don't rattle under acceleration, check if there is something loose at the engine, check the transmission bolts and nuts, check the exhaust and exhaust brackets. Check the kick start lever.

[@jacobperei9191]

@@scooterstreetau just a quick update if someone has the same rattling: Yesterday I removed the clutch drum and saw that the 3 pads on the outside of the clutch centrifugal unit had pretty shiny surface which is not good. I sanded them down a little bit with 100 grit paper and I also sanded the inside edge of the drum because that was also too shiny and slippery. Cleaned everything with brake cleaner and the noise is gone 😁 thanks for the tips anyway!

hey, can i use polini 3g for race clutch on my yamaha slider? it has a 50cc motoforce cylinder kit

[@scooterstreetau]

Yes

[@egmedicus]

[@scooterstreetau]

Thank you.

[@kokimafija]

is it safe to mix rollers i want to mix 5,5g and 7,2g

[@scooterstreetau]

Yes this is fine, but not for long term. Use the combo method for dialing in the roller weight and then match all 6 rollers with the totla weight of the combo set.👍

[@iamandreja]

Hey people, love your channel, bunch of useful stuff. I would like to upgrade my electrical output on my 2000. Piaggio LIberty 125. It is a pre-leader engine. I use my scooter daily, I commute with it, I travel and I need my heated grips to not drain my battery after starting it for 20 times a day. Sometimes I turn the grips off and I use kickstarter to recharge my battery. But I would enjoy not having to do it. Do you have any advice?

[@scooterstreetau]

You could start with another battery that has a higher amp hour rating. I prefer to fit a second battery which powers the heated grips. Connect the main battery to the second battery by way of parallel, voltage stays at 12V. ( google Series and Parallel for 12V batteries). Use an isolation swith which isolates the power between the 2nd battery and turn it on during riding when you need to charge the second battery. Use the 2nd battery for the grips only and not both to start the electric motor. For best results seek professional help when fitting electricals.

[@iamandreja]

Thank you for the super quick reply. The thing is, my under seat compartment is full of tools and spares, tire sealant (I am prepared for anything :) ). And there is no room for battery that is bigger than the stock one, I'm afraid. I'd rather buy another stator with bigger output but I've never heard of aftermarket ones. Thank you for the idea, I will keep it in mind.

[@scooterstreetau]

All the best. Let us know the final result.@@iamandreja

[@jokubaskuodzius4248]

Hello, I have a aprillia sr and i bought full polini hi speed transmission kit with a belt but when i put it all together there i a gap between drive boss and the belt, i am also using stock spacer in the back so why it wont fit nicely?

[@scooterstreetau]

Check the fitment for the Polini part number to your Aprilia model. Check the fitting instructions. Where did you buy the kit from ask the supplier as they will be more familiar with the parts you bought.

[@r0bin498]

Also the belt deliverd with that transmission kit is dog shi, it made my 70cc aerox slow ash so i got a malossi kevlar belt instead

[@JamesAngell-c6h]

Hi ive got nrg mc3 im up grading variator clutch and bell belt all malossi also going with naraku torsion controller the one that spins and malossi torsion controller will i see much gains on standard topend or would i need to 70 kit im also running gianelli pipe

[@scooterstreetau]

If there are any limits on the potential of the factory parts, the answer is yes. Replace one part at a time then test ride. Do not put everything in all at one time. Gains will be made with the variator roller weights, not too light. If the belt is slightly longer and there is travel on the variator will equate to more top speed, shims can be used if take off is lost. Dont use Kevlar belt. Special is more beneficial.

[@JamesAngell-c6h]

hello i have a kymco agility 50cc 4stroke does the malossi clutch help for top speed ore faster take off?

[@scooterstreetau]

No. You need an engine upgrade. Try the variator shaft, Malossi variator and clutch springs with rollers.

[@titasjon7122]

Hey im planning on upgrading my cvt with the poloni hi speed minarelli kit or the malossi mhr 2000 kit which should i choose? And if i upgrade my carb from a 12mm to a 17.5mm does my top speed increase by a lot?

@@scooterstreetau that sucks. Seems the price of a belt for a zip is triple the price than we have here in the Netherlands. Ironically I find our prices here expensive. 😅

Hey Brad! I have a Vespa LX50, now with an Athena 70cc pro sport, Sito plus exhaust (for stealth look) Malossi 2000 variator + rear spring, standard clutch with Malossi springs. Sticking with the standard 17.5 carb so far as I understand that gives better low end torque compared to a larger size. …just want to say that I have been looking at very many of your videos and really enjoy the way you break things down and explain in such good ways. Such an asset! Keep up the good work and thanks for sharing your insights and knowledge!

[@scooterstreetau]

Thank you for taking the time to write this comment. Encouragement and support like this is truly amazing to hear! The smaller carb give low end and economy for the daily rider.

i have yamaha neos 2006 50cc stock and i have performance exhaust and 5g rollers , in the variator there is a small washer maybe 1mm thickness can i take it off and get some more speed and torque ?? and thanks for this video this help me a lot

[@scooterstreetau]

Hi and glad it helped, the small washer in the Minarelli is part of the outer fan. If you remove this you may gain a touch more top speed but the initial takeoff will be slower. Move to a performance variator or start to shim the shaft and replace to a better performing belt.

[@bogdanbogdan6094]

[@paulbudford]

Another great tutorial . 👍 CVT tuning is so simply complicated. It really is a balancing act. I always found with the Kevlar belts. They would wear out the variator more quickly. So the belt you recommended sound ideal.👍

[@scooterstreetau]

Hi Paul, yes, they are so stiff when they new too. They don't roll as easily as the Specials.
