That is a very nice comment, thank you for acknowledging our efforts🙏

Alan, Thanks for watching and glad it was of value for you👍

Thank you, we appreciate your kind comment and the views👍

couldn't agree more, spot on and to also go through a worn down one for comparison what can happen and prob will if you are lazy with the service ^^

Hey, we appreciate the love, thank you🙌

You are welcome and thanks for wacthing our Channel🙌

Awesome🏍🏍We look forward to an update🤙 and thanks for supporting our Channel.

Thanks so much 🙌 and big welcome to our Channel.

Thank you🎩

Did I miss the rest of this conversation?

Clutch shudder is caused by the clutch shoe contact pad skipping. The transmission should be serviced at regular intervals.

Thank you. For these small scooter variators there is no grease supplied/required. On the larger capacity scooter variators, you will notice the basket has rubber seals and these are the kits that require grease and the grease is applied to the shaft. The instructions will always guide you.

Thank you. Try 5-10% lighter in the rollers and increase the clutch springs tension. Test mutiple roller weights.

​@@scooterstreetaushould i change my contra springs too?

Not at first, make only small changes and test before adding another part or change to the system.@@ineedmorecarrots6063

Howdy, it is when the engine reaches the 6000km mark you will notice signs of wear so at intervals of 3000kms is a good time to check. Rollers and sliders both slide, Dr P has a great system in their shape and they all designs wear and which ever design you choose maintenance is the key. Dont mix them, it is unnecessary. Thanks for wathcing and the great Question🙌

@@scooterstreetau Thank you so much. Y'all ROCK!

You are wasting your time. Just so you can learn- give it a go but it will let way too much air in and the bike will not run properly. The Fuel and air ratio needs to be balanced. The Kymco Agility is a snail but you can do engine upgrades to make it a racing snail..🤙🤙🏍

The brass housing itself is not available but you can replace the complete basket, Malossi has it as a spare part. Search for the variator part number on Malossi website, select SPARE PARTS and you will see the MOVABLE HALF-PULLEY FOR MULTIVAR 😁

@@scooterstreetau Thank you so much!

The bronze bush. Is 3 bucks for a Chinese 50cc scooter. Bill

@@williamhaskellhaskell3162 Thank you; I think you can teach the channel some about correct terminology 🙂

Without knowing what noise I guess you shoud check the diff gears and look for wear in the Transmission, You need to discover the exact location of cause.

All of the Chinese GY6 are the same, the transmission is different in terms of the case length which is usually determined by the wheel size. Check the engine prefix, 152*** is 125cc 157*** is 150cc.

The Storm is a cool scooter to tune, rebranded Piaggio Typhoon but with better wheel/tyre combo. What you have described is the perfect description of a bike with an air leak. You need to check your airbox tube (which leads from the airbox to the carb), your intake manifold (from the carb to the engine) as the Piaggio engine in that bike very commonly develops cracks in these rubber parts with age, leading to exactly the problems you've described. If these are both intact, check your reed petals, if intact you may have a crank seal leak.

You need to retrace your steps. If it wasn't making the noise prior, it stands to reason the cause is something you have done when you have removed the variator. Does it Knock after riding? Did you put the parts back together in the correct manner?

Yes Ok, check the transmission, what is the roller weight and check the belt against the measurements for the factory belt..

I am not sure of the engine swap but try an exhaust and carby adjustments, just ride it for fun and giggles as they are a classic.

Hi Mojfilter96, thanks for joining in🙌. The Zuma is very responsive to any changes, consider an Exhaust, Carby or main jetting and transmission start with Variator. Yes there are heaps of parts for this very popular model.

@@scooterstreetau thanks for the quick reply. Is there a variator washer on these? sorry for the hassle! I had the exact same one in 98 when I was 16, and I've been looking for years and years and finally found one. 1 owner from new. Kept in a garage. Amazing condition just tops out at around 30mph which is way too slow man.

@@mojofilter96I don't believe so but you will need to check! the speed sounds normal, so unleash the beast..

Hi Wow, I hope you were not injured.. Usually when the belt explodes it would not STOP the rear wheel, because the clutch is driven by the clutch shoe activating the clutch bell and then engaging the diff gear. If this has happened do a thorough investigation in to any failed parts especially the clutch shoe, which is the driving point..⚠⚠

@@scooterstreetau yes sir, i changed both rear and front brake shoes, they were totally worn out. I'm fine thanks for your support and concern!

@@cox_stuff4530 Also check the CLUTCH SHOE... 🙌 Good to hear.

Go back to the start prior to any mods when there were no issues, now fit 1 part at a time, test the change before moving to the next part change so you can isolate the issue.

Yes, this is pretty common on that engine. The torque driver (rear pulley system) on both the 50cc and 100cc Minarelli engine use a 2 pin system, which is highly prone to wearing prematurely. This causes the rear pulley to suddenly drop open (which rapidly increases the gear and drops the revs) rather than smoothly transitioning into a higher gear as it should. You need to replace the outer face of the rear pulley (torque driver) with the Malossi unit. Its a pretty easy job to do, we have another video on this exact issue and how to repair.

Usually only at transmission service intervals, they will get a little dusty from roller, guide and belt debris caused by wearing. Best just top wipe the out, or clean with brake cleaner. Definitely no grease whatsoever in the Variator, unless you have a MHR Team performance Variator which requires it (these variators have rubber seals at both ends of the bush shaft in the basket to keep the grease captured).

No we dont have. The TGB variator was already at the high performance, they were makers of many Variator for other companies and had a great product already. One of the issues was the spacing shaft had a small instep on the crank side that sat over the crankshaft and this was not a common set up, other variators used a solid shaft with out this step.

You can see the wear on the rollers, it is very clear to see, so don't worry too much as it will be very obvious.

First number (larger number) is the diameter (outer rounded edge). Followed by the width (flat surface measurement). Example 19mm Diameter X 15mm Wide.

Have you checked for limiters? Check the CDI and the intake - reed valve. What air box system are you running? Is the belt progressing to the outer limit of the variator? Do a Pen test,. The rollers could moved up to 6 gram or even heavier. A higher end exhaust will help. If all works out consider a gear kit to transfer the power into higher top speed.

No.

Sport Variator for this set up. Switch to an Oversize when you upgrade the cylinder.

@@scooterstreetau Ty! That's what I thought too!

@@jaakkotoivanen3437 😎👍

Sounds like a classic torque driver failure, or torque spring failure. The Minarelli engine is particularly bad for it, but it can happen to other models too. I would recommend removing your rear pulley and inspecting the spring, as well as removing the sleeve to inspect the pins and slots of the torque driver too.

Rollers: In a perfect world, the effect will be a slightly slower acceleration. If the 13g rollers are possibly already the optimal weight for the variator, if by chance they were too light you would be missing out on some top speed. If it was me I would test and trial several different weight sets to find the best set for what you want from the machine. Fuel: If the riding situation des not change, the consumption will have no noticeable difference.

In the larger capacity scooter there is application for grease. In the smaller scooter I do not use grease. I would suggest to give it a go and see what happens, you will find out immediately the result.

@@scooterstreetau thank u bro

The roller is trial and testing, you need to start some where (the supplied rollers in the kit) and then adjust from there. Only do one change per time and take your time👍👍

@@scooterstreetau ok I think I'm going to put 6 gram rollers and put the purple spring that provided me with the Malossi kit

@@mohaa04 Do the rollers first and change nothing else. Do the test ride and not the change.... 2nd then you can change the spring and again, do the test ride so the change can be noticed.

@@scooterstreetau ok, i will thank you

Lighter rollers and tighter clutch springs, don't expect mind blowing result. It will only enhance the standard setting, 10-15%

Yes, we always place the roller with the closed end or capped end of the roller toward the clockwise direction of the variator. Due to the variator spinning anti clockwise using this method keeps roller inner and outer together. Good quality rollers are glued and it will not be super important but a good practise to apply when setting up the variator.

@@scooterstreetau thank you for replying ! This will help

@@ram457moreno 👍👍

And i have a doppler clutch and also wonder whats the difference between tight and not tight spring

How fast it the current top speed? I would try for a Malossi variator, with a range of rollers. They must be tuned to the individual bike as well as the rider weight. We sell the variator as well as Polini roller tuning kits on our website

@@scooterstreetau ok thank you

@@hamalou161 Tight spring tension will delay the take off. Low tension will engage the clutch early at low RPM.

Check the Polini variator Part number for its compatibility for your Model. The Yam Aerox Variator shaft dimension is: 20 x 13 x 37+-mm

@@scooterstreetau Thank you for your reply, I'll try it. Thanks

@@scooterstreetau I just checked it and it says that it is supposed to go on a Yamaha aerox with 13mm crankshafts. But for some reason it does not go on mine.

@@naurioxx2409 Let us know how you go..

@@naurioxx2409 Take a measurement, it maybe the wrong part or worn 🤷‍♂

Without knowing the scooters history, hard to know. It my have an electric restrictor, look in the Peug forums for details on this.

@@scooterstreetau i put in a doppler derestricted cdi and it derestricted the revs but it still doesnt rev high enough

@@pomaranc3647 You may have several restrictions, the transmission, in the carby and always the factory exhaust. Check all of these areas thoroughly and upgrade the exhaust when you're ready.

Never.. The smaller variator should run as a dry unit. Graphite powder has been used in the past but I prefer a clean transmission free from substances. The larger CC variators are an enclosed unit when assembled and they do have a very light grease that remains inside the unit and will not leak to the belt.

We don't have that model in Australia, I'm not sure what size rollers it takes. I would recommend removing one to measure and weigh, there's a very high likelihood it uses a common size which you'll be able to get online.

@@scooterstreetau yes, that's just what I'm thinking, will update :)

@@RamSharma-90_64 ok.

The factory weights will probably produce the best top speed. If you go heavier ( which I would advise you try) you may notice a drop in the acceleration from start. Fitting clutch springs will enhance the acceleration and trial of heavier/lighter rollers will allow you to find a best performance result.

@@scooterstreetau thanks, are you planning on uploading anytime soon?

Which engine? Any of the ones that you list are good. The Malossi Team 2 is great but in some models the Electric start will no longer operate.

It's a 70cc mk2 stage 6 sir.

@@jamilcarmelo2945 Which engine Piaggio/Yamaha/Honda? The Malossi Team 2 is a variator..

Oh my bad. Its a Yamaha sir.

Anyways,Thank you sir for replying.🙂

You have a huge mismatch there between the cylinder and exhaust. That C16 starts making power where that cylinder kit tops out. If you installed a Yasuni R or Z you'd have a much better power delivery.

@@scooterstreetau It previously had a Technigas that was awful, but it still topped out at 50mph, somethings restricting it, either that or euro4 are just slow

@@PaulioMaldinio What model Tecnigas? We have found the E4's are incredibly punchy and powerful when they're tuned correctly.

A performance Variator generally gives exactly that, better performance. In some models of scooter the Variator can increase the acceleration, increase the delivery of power evenly through the rev rage and in some cases they will increase top speed. Certain Race (Over Range) Variators have larger dimensions then that of the original and add an increase at both ends of the speed line.

No not necessarily, best to try and see what effect it has. Lighter reduce the engine load easier rpm, too light and the top gearing won't be met. Too heavy may impede the acceleration but can give higher top if not meeting the top gear potential.

@@scooterstreetau thanks for replying. I have a 125cc .. it’s dog slow on the low end. What should I use?

@@ivlark1 Most likley there is an issue with engine or transmission. You will discover when you start to open up the cover. In a perfect scoot you would lighten the rollers by 10% to start and fit a higher tension set of clucth springs to the clutch shoe.

Check the Auto choke and fuel system.

@@scooterstreetau will do

Cool, 2007 C3 got it new, There were a # of recalls on it " rode " it in to dealership ROCKRIVER YAMAHA Jefferson wi. and had to pick it up in PARTS. Not all the parts were there.Fat a$$ old guy and I Know it. I ride year round, late night so a lot of animals out there. I have pol. speed var. dr. pulley weights.Small air cleaner, Mod exhaust. Looking for anything to help keep going. "guides" are all the same? or can get a bag of them? somewhere? Thank you

There are several Polini and scooter daler is the US that sell these parts, start to google and you will see, best of luck🦈@@bobgleaser7106

Thank you TVW. We love to get the comments and will always reply, very glad you like the production of the Vid, looks like we need to work on the content for you. You may have missed some info, so I'll help out, watch from 1:20 and at 3:00 the components replaced when servicing the variator. In understanding the function of a part you can then better understand how to look after and keep the best function. The direction of rollers placement for each manufacturer is different, If you have a Malossi Variator just follow the instructions in the manual. Overall we have the closed end of the roller if produced in that manner facing opposite the direction of travel. Cleaning is a great idea, always remove the dust and particles that could wear or inhibit the correct function. Many of the workshop manuals have different names for the same part, such as HUB, DRIVE BOSS, COLLAR, BUSH and SPACER. We don't mind what you prefer to call it, we understand what you mean👍You refer to a couple of names for the DRVE PULLEY, VARIATOR SLIDING HALF, DRIVE FACE, VARIATOR BASKET, MOVABLE DRIVE FACE COMP. If you need some help with something in particular just send us an email, will be more than happy to help with your variator😊😊

Yes the rider complained the top speed was 30KPH and he was riding for months. Service your machine guys☝

The fan may have damaged such as crack and flew apart. The Crank nut may have come loose? There may be another mechanical part in the CVT that has caused this. Regular maintenance is the best, but not always prevented.

@@scooterstreetau i took everything out put it all back togetyer and it sounds fine but whenever i ride it it will only reach 10-20mph and make a horrible motor like noise then decrease in speed

@@twiggy17 You need to reinstall correctly and replace any damaged parts. Keep working on it and also look further because the fan may be the result of another parts of the engine.

@@scooterstreetau alright cheers gonna do that now

@@twiggy17 Study every piece and ensure rollers are inserted correctly and ramp plate.
