Why You Need To Install A Performance Variator On Your Scooter

www.scooterstreet.com.au
In this video we discuss how variators work, and what difference installing a performance variator will make to your scooter.

[@mudachuka12345]

Thanks for uploading your videos are always great to watch. What’s your thoughts on performance reeds? Is it best to go with standard.

[@scooterstreetau]

A pleasure, thank you. We found the performance reed is one of the parts that is required. The standard reed valve is usually smaller and suited to a smaller flow and requirement for the standard cylinder/carby/air set up. SO why upgrade the other parts to have run into a bottle neck.🤔 Do it if the other parts have been upgraded. The reed petals are always a part to check at the service interval.

[@andru9102]

Thank you for all your videos. I recently bought a Vespa 50 2 stroke and 2 stroke to have a play with. I’ve learnt so much from your videos. sounds like I can get quite a bit of performance improvement from the two stroke, although for the four stroke, perhaps the only thing I can do is add a performance variator?

[@scooterstreetau]

Your welcome, glad you enjoy watching👍 Yes true the 2 stroke is much more rewarding for the dollars spent, and easier to start with. Enjoy your tuning journey and thanks for watching.

Hi Scooter street. Love these videos. Would you say on a Yamaha bws if you have a Malossi performance variator with some mods. Do you need to change the rollers to the same size as factory and do you need to change them to the same weight as factory?

[@scooterstreetau]

Thanks Duke, The Malossi weights are a different size to the factory so the answer is no.. You can approach it this way, start with the Malossi rollers that are provided in the Variator kit. Ride and trial these so you get a good feel of how the engine performs and then head back to the workshop. Now you can start to change the roller weights. With a test ride after each change you will then have a starting point to compare if the ride is better than the original set in the Variator, or are more changes required. I hope this makes sense.

[@vdj951]

[@Magnetis0101]

The motor on my Vitacci Spark 150cc has plenty of power but the top speed is terrible along with the gas savings, I've only had this scooter for 6 months. Your video's are wonderful, things i will be trying out. More people need to own 150cc scooters imo. Also the sound in this video is very low, I have mine turned up on software and hardware.

[@scooterstreetau]

Hi ACP, thanks for coming onboard👍 Nice looking scooter, it reminds me of the Scoots in Thailand. You should try the variator and also if it runs with a carby system check the main jet it maybe running richer than needed. Also a gear kit increases the top speed and works very well on the 125-150cc. The voice can be annoying so you are lucky with the low volume😂😂😂😂 all the best.

[@petekaiser]

Good thing found this...its also great that scooters are common here in the philippines and choices for performance variators for the scooters vary, but for the vespa's in general we have malosi, polini and 12S (locally made variator) which really gives torque that would result in accelaration that we would need in order to overtake someone ❤

excellent videos guys, really informative and clear for the newbies! question..on your webstore you have two different performance variators listed for the cpi based scooter (polini & malossi)..apart from the obvious extra set of rollers in the malossi kit, is there any difference between these two kits? which do you recommend for a cdi unrestricted with no engine mods as of yet? thanks guys thumbs up*

[@scooterstreetau]

Thank you Brother👌 Essentially they are the same. I recommend replacing the outer fan with this model when installing a VAR. Change the CDI when you hit the rev limiter.

[@bigboomer12345]

ok so update to this, put new malossi var with fan, new malossi clutch and new malossi kevlar belt on and its running great, heaps better accelaration but now i feel like its bogging down from stationary at lights for like 1 to 2 seconds, is this roller weights related? (i installed the 6gram weights)or is it just because its a completely stock engine apart from unrestricted cdi?@@scooterstreetau

[@notydino]

Thanks Brad for the in depth explanation. I'm looking at Malossi upgrades for a Vespa Sprint 150cc. It should be the 2000 kit. I'm told by the shop that I gotta choose within acceleration or top speed, that I can't have em both ways. Yet, the internet testifies that I will get improvements in both. With casual understanding of gear ratios, if i do get improvements in both, where's the top speed coming from? Does the kit have an oversize variator, therefore i get a bit more top speed?

[@scooterstreetau]

Thank you✌The ramp plate angle and the rollers is where the advantage will come from, I would lean towards the opinion of the shop. How much top speed are you desiring? If you want lots of top speed you have the wrong bike. Scooter are about acceleration and manoeuvrability in traffic. Luckily for you the Vespa looks really cool too, Win win. The Variator does work in these models. We have a video on this.

[@notydino]

@@scooterstreetau You're right, scooters aren't made for speed. While it's nice to have a bit more top speed, not losing any would be my main concern. Since the top speed "size" of the variator is the same, wouldn't the top speed be the same anyway?

[@scooterstreetau]

@@notydino Yes, if your rear pulley and belt allow it to go to this position.

[@bassboostedmodz9466]

Hi there watching from sweden. I have an kymco super 9 ac and from stock it went around 30mph and when I shifted my restricted boss drive to an unrestricted one it makes around 40mph and accelerates alot slower. Any idea what i should do to gain more top speed without losing more acceleration?

[@scooterstreetau]

HI and Welcome🦘. I am unsure why it losses acceleration. So you replaced the variator shaft to another? Was it the same length. Let me know and I will try to work out best answer for you. Usually changing the shaft will not have an effect on the take off, it only adds to the top speed.

[@roel7930]

Hi really learned someting after watching this video, I hope that you can help me with something. I have an aerox 2T everything standard the only thing i changed is the varioring and the plug in the exhaust and i am already going 70kmp gps. Im gonna change the exhaust to a gianelli reverse and i ordered a multivar. How do thing that this will change my topspeed and torque. Because right now my scooter really feels slow the first 40 kilometers. Thanks for ur help!

[@scooterstreetau]

You will require a Cylinder upgrade for torque and top speed. The Gia. Reverse is a great performer on the Aerox so match it will a high class street cylinder. The exhaust and variator will give a good increase, expect 80+KPH.

[@KikoBee]

Just got a performance variator on my 125 Vespa and it sure made the scooter a lot more livelier

[@scooterstreetau]

Yes they certainly do work✌

[@cliveswabs9365]

U can slightly fill the ramp with epoxy so theyre steeper and file the inside to 0.5 mm so the rollers go higher

[@murangnukun4836]

For Hilly areas.. is it okay or can I use a lil shorter belt thn the stock !? What about the wideness of the belt ? Alil shorter and lil fatter , wider will be okay ? Lastly are all variator, clutch size same?( Especially the hole)

[@scooterstreetau]

If the current belt is in the lowest possible gear then a different dimension belt will make no difference. Wider belt will not get to the lowest gear and the scooter will be very slow to accelerate. The answer for hill approach is in the rollers and the clutch sync. The variator must move to a lower gear when the rev drops and this is doe in the rear pulley working with the correct roller weight. The variator hole (Shaft or Hub) is set by the crankshaft dimension. Variator and clutch, No not all the same.

[@nikhill6917]

What variator would you recommend for a Suzuki TR50 Street Magic running a stock piston/cylinder (will get a Malossi Sport 68cc big bore and 21mm carb in near future) with derestricted stock exhaust and derestricted CDI unit? Ideally we’re after a top speed of around 80km/h before we do any engine mods.

[@scooterstreetau]

I do know Malossi make the Variator as I fitted to the Street magic many years ago. The Variator will not provide the 80kph, you need the BBK. (Big Bore Kit)

Try a Polini 3G clutch so the engagement of the clutch can fine tuned this will give more control on the grab of the clutch.

No. the variator will allow finer tuning and depending on the scooter model give more acceleration.

There are many compatible parts for the Chinese scooters. The engine number may give an idea of the engine type. It could be GY6 or later model.

The stock is a good choice when only fitting a variator. We found the stiffer kevlar belts give resistance due to the rigidity of them when fitted with a 50cc engine. In the 50cc the flexibility of the belt is key to allowing easier RPM increase.

@@scooterstreetau and how about sliding sleeves wich one should i choose 13mm or 16mm

[@scooterstreetau]

@@MacMake99 You need the correct one for your scooter... The sleeve is already in the factory variator.. ?

[@MacMake99]

@@scooterstreetau i have the stock one now but i have another one wich is little bit longer

[@scooterstreetau]

@@MacMake99 Be very careful if you fit the larger sleeve. (Also know as the variator shaft or hub). The longer sleeve will set a different spacing for the parts that sit outside it and will cause some parts to collide resulting in the Big Bang💣💣

Hi I have a Piaggio zip with only 3k miles. Completely standard other then sports pipe. When I bought it I noticed the side casing was hot to the touch after short rides. I took the casing off and the belt had been rubbing bad and there was bits of rubber all over the casing. I’ve replaced the belt and cleaned everything. Checked the clutch is moving free and it’s still getting hot. Any ideas?

[@scooterstreetau]

It should be hot in the transmission case as there is friction involved, it is the job for the cooling fan on the front pulley to kep the air regulated, is the cooling fan in good order? Also the belt should not be rubbing.

[@williamhaskellhaskell3162]

Does the cooling fan pull in outside air or just circulate air? And or is outside air forced in the case. Or does the rear vent pull a vac on case air? As the bike moves forward?

Hi me have a 150cc gomotto me did the engine to 200cc and a pervomins exuast but get 80 kmh uot of it on 80kmh the ref is hi needs one more gear

[@scooterstreetau]

Check the belt and make sure it is going forward on the variator to the outer limit, you may need heavier rollers...

[@BokiRS]

What about higher speed on lower rpm. Can u somehow do that any other way

[@scooterstreetau]

Gear up kits can allow this. The rear gear that runs to the rear wheel.

Can you also state the cons of using a performance variator. Also if you use a performance variator, do you need to change the rear part?(female sheave/clutch part) so that they have the same angle?

[@scooterstreetau]

Watch the video, it is all about why performance variators improve the performance of the transmission. No, you don't need the Rear pulley upgrade. You do not need these parts, you just want them😁

Can I change my variator in my 125cc 4 stroke scooter??

[@scooterstreetau]

Yes, certain brands have a fitment for each make and specific model.

@@damedkhar2912 I have not heard of this model, did you ask the shop where you bought it? You need to find out from the Variator manufacturers, there will be a similar make and model that has a fitment.

And that is how your scooter tuning journey began. Nice work🫡

[@bl4go268]

Is it safe putting it on my gy6

[@scooterstreetau]

These parts are made for scooters, there is a correct fitment for each common scooter engine, so please ensure you use the correct Variator for your engine.

[@henrycisneros9643]

So with changing variator for top speed does it lose low end torque or no ?

[@scooterstreetau]

Only certain models will increase the top speed when fitting a variator. A good understanding of the variator to help get the best out of the transmission.

Why don't manufacturers put performance variators on scooters from the factory? Why send them out with sub-standard variators? Surely they know about performance variators - couldn't they just copy them? Thumbs upped.

[@scooterstreetau]

Yes good question and asked many times. Fitting the basic option variator from factory is cheaper and also stays within the 50cc category restrictions. Most 50cc scooters are made to suit counties which have strict speed and power restrictions which they deem safer for first Licence riders. Where I am from the speed is restricted to 55KPH. So the manufacturers make the scooter to fit within the guides lines of the Regulator/Government.

[@huncho9319]

when u got a piaggio so there is no need for other variator

[@paulbudford]

You could leave it alone. The Piaggio variator is much better than a Yamaha one. But it's still made to a price point. They are made as cheaply as possible. Fitting a better quality part is never a bad thing. It's definitely smoother with a performance version. And holds the revs more consistently.

[@sane6096]

@@paulbudford what about peugeot variator

Would still benefit from a better performing variator. The Peugeot ones are not as good as the Polini, or Malossi variator. Very much built down to a price.
