- Scooter CVT tuning, We give a little insight on what not to do. CVT transmission tuning isn't too complex but important, We explain a little in this video and show you a Aprilia sr50 that had some issues if you're looking for an in depth description of all the CVT components, what they do, how they work, and how to diagnose and tune. We have a video explaining that.

My first scooter was a 1986 Honda Elite 150D I bought in high school new and rode until I sold it in 1998. Just bought a 2008 Benelli Andretti X50 and it needs work to run again but am going to give a little more oomph to it. Found your channel and am subscribing this is helpful stuff.
Very cool!
Love this show!!!!!!!
the swapshop show!
Love it
I’m happy to say my cvt did not explode on the Honda Navi using y’all’s deluxe variation kit this time.
gday so I've got a 2006 piaggio zip 4t an the problem is when i open the throttle up it just wants to bog down, when i slowly give it throttle it starts building speed just upto 42kph could i get some help?
I learn so much.
good!
Hey.,i have a Aprilia leonardo 125cc 1998. What other brands scooters have the same CVT so i can find correct springs for the torque and clutch? And maybe even the rear part itself as the grooved slots the clutch rides on are worn so the scooter is sometimes stuck in high speed and are slow to get acceleration again. Please advise. Thank you from Norway
man i got 13,000 miles on the belt on my 2T Zuma bugeye, still going strong to this day.
hello, I have an aprilia sr 50 ditech and it only goes 80 km/h.
it has malossi rollers, malossi belt and malossi central spring. what should I do to make it go more than 80km/ because I know it can.
Love your vids, my ‘01 bug eye falls flat on its face under load! I get high revs but go to take off and nothing is there jus bogs out and chocks our. Suggestions, opinions or ideas are very welcomed. TY be safe and test negative!
Hi Michael thanks for the comment! Feel free to shoot us an email at paul@scooterswapshop.com. We can set you up with any items you may need
Gonna get a 125cc license next year or so and binging this channel to learn everything
awesome thanks for subscribing!
never thought i'd see negan fixing scooters
@scooterswapshop hey so I just bought a 2018 genuine roughhouse sport scooter and it came with the restrictor off and it tops at at around 45mph what would you recommend on upgrades for the transmission and exhaust ? Would like it to go faster but don’t wanna make it where I can barely go up hills, I live in Connecticut so there’s hills. Thanks in advance for the help
45 is about what your gonna get out of it but call the shop talk to paul he can tell you if there is anything you can currently get for it
Interesting, what do you reccomend for a 150cc? I got banjin driveface oko variator with 12g, ncy clutch and ncy 1500 contra spring. When i was completely stock i was able to do 60 with 17 rollers and when i slapped those parts i lost about 3mphs even though i went lighter on the rollers im not reving near as i was before.
you need to take it one step at a time when tuning there's no weights I can tell you to use that's gonna achieve what you need all pieces work together.
17g rollers and a light contra spring is gonna give you the best top speed at low R.P.M...
Hi newly subbed here from ph,
I have a 160cc (upgrade block) scooter should we have a more stiffer conrta spring (1500rpm) and softer clutch spring (1200rpm)? or is it the other way around?
thanks
Im thinking of getting a yellow contra, malossi one for my peugeot. It has the akrsal t6 asso mext r pipe 21 carb and the belt is splipping and the clutch is slipping so im getting a malossi fly but was thinking about getting the yellow contra, do you think it would be good and not overkill?
How many rpm is a yellow contra?
@@ajc5601 i dpnt know it just says 30% stiffer its their middle one. Red is stuffest then yellow and white being slighty stiffer than OEM at 5%
call the shop or message us on the app
@@exapioz3075 Just get a white one and a yellow one and a set of rollers.. if ur making like 5hp u could run a yellow one and ajust with the rollers... i liked going yellow and stif springs on the clutch in the back.. so the pickup was at like 2000 rpm... and then ur really taking off.. with the white ur stuck at going very light rollers.. that can make it harder to ajust.. but going red is never reccomended for a normal scooter.. going yellow is more fun but ur also going to need a new belt/clutch and rollers about every year..
Wonder what kind of clutch springs he was using probably 2000rpm also I alway try to stay under 1500 on both them if I can for some reason I have a stock kymco agility125 that has a red spring in it previous owner told me he bought it new that way it takes off fine and the belt looks fine so I been running it that way but my pre bug with a 70cc polini sport kit I run a 1000rpm contor and clutch springs I like to get off the line quick if I need anymore I'll play around with the rollers to get more
nice
Scooters WAP shop.... love it
I came up with that one, you're welcome lmao
The best!
Patrick did by accident 2 years ago
What do you think? I have 2007 yamaha c3, Polini speed variator, 4.5 dr pulley sliders, Stock springs and contra. 29 to 35 mph What can I do? Kit came with blue contra Should I put that in or a different color spring. Thank you.
Hi you’d want to reach out to the supplier you got those items from. We don’t really do any tuning on the c3.
I don't have any power tools & ratchet gun etc. I only use good old box spanner with torque wrench. How tight should i torque pulley and clutch bell nut?
your going to ned a tool to hold it we sell on the site
I just got an Aprilia SXR 160, it barely does 100kmph, rpm doesn't go beyond 7k, scooter moves only around 4k before that it doesn't even try to move. Everything is stock. But the same engine specced Sr160 does 140kmph. Is there anything I can change to make it a bit faster?
I’m sorry I’m not sure we don’t have those bikes here. Sounds like it’s restricted
Great video I have a 2022 ADV 150 stock I am getting 65 MPH I am wanting more top in and quicker acceleration which variator set up with sliders would you recommend and slider weights I see you have two of them on your website. I am 250lbs
we have a 75 mph kit.
@@Scooterswapshop do you guys have anything for a 2023 zuma 125?
I have a very rare gy6 reverse trike meng 150 side by side, is there anyway you could tell me in inchs the distance center to center between the rear clutch and the front compenater thanks i need a new belt and want to make sure i get the right one,
On a regular one so I can see if mine is the same I have a reverse on mine so it may be different,
Hi you should measure yours to know the length needed
Yo I’ve got a gy6 250cc bike (can see it on my channel) I’ve alr got derestricted CDI new coil and spark plugs and new nibbi carb was looking to CVT for next tuning and upgrades any ideas like race clutch or anything ? It’s new bike only 1200 miles haven’t changed the CVT belt or gear oil yet.
Also max speed is like 70-75 mph btw, seeing that some 150-200cc can get that I’m sure I can get more with a 250 gy6
can i ask if it os okay to run 1000rpm center spring and 800rpm clutch?
call the shop and we can get you the proper parts
hey, love your vids! i have a vivacity, ordered malossi sport kit, stage 6 pro rep exhaust, 21mm carburettor, and i have no idea what CVT setup i should use. can you help me please?
Please call the shop we can get you the parts you need
@@Scooterswapshop that’s the whole problem, sadly i’m from europe and i’m unable to do that.. :(
@@nojus7185 ok. It would be best to reach out to the company you got your components from or a local one that can help you on your specific setup.
can some one help me please ? , i have a nitro 50 cc 4 stroke scooter/moped , and the CVT is not turning but the clutch is , and the fan is not moving what do i do ??.
TAKE IT APART AND TROUBLE SHOOT IT PART BY PART IF NOT THAT TAKE TO A LOCAL MECHANIC
Hello guys! Thank you for all the tips and great videos!!! I recently upgraded ...and want to hear your expertise on roller weights!? 2004 Derbi Atlantis Bullet et2 piaggio engine. Setup: S6MK2 sport 70cc, S6PWK21 carb, S6 intake system and reeds, Yasuni R, Malossi 2000 Variator, Green Polini springs, original crank, contra spring and belt. Still tuning...friend recommended the Athena racing long belt. I am currently with 5 gram rollers and the scooter ripps awsome! Didn’t push it too much for top speed since was around 40F and super windy...got 65 on GPS...My question is have you tuned that cylinder before, what’s the optimal rollers? I also have the white Malossi spring that came with Malossi Multivar 2000 variator. Thank you! Any coments are much appreciated !
we have many videos on cvt tuning!
the way u say "malowssi" is funny
I have a 50cc taotao 1p39qmb Veloz scoot. I'm getting fire to plug and gas.But its not wanting to crank what could this be
air leak or 100 other issues
Check the compression!
Hello, do you ever tuned PCX variators?
yep
What was the common issue it came in for??
Is it possible to transfer the motor from yamaha aerox to peugeot jet force?
Anything is possible, if you have to ask it may be a little too complex for you, may want to find a fabricator
I have a Yamaha nvx 155cc what's a good racing transmission step up ?
we dont work on those
Im running a 1k rpm contra spring in the 232. But it def is a drag bike.
Ok think i got wrong springs for my zuma 50. Bought a red contra spring and clutch springs with a 4g rollers.
yeahhhhhhhhhhh
I have a Yamaha jog r with stage mk2 Racing Ac and i have a malossi red spring do i Need to change that
nope i dont think so only if you are running original cilinders or something like that but maybe go yellow mate
No
If it works it works I would test a yellow spring and lighter weights maybe and if it runs better the way you had it then there you go
@@nastynatesscooters9896 yeah yellow would be a bit better i said that to
Use the lightest contra spring you can without any belt slip.
my aerox 50cc runs a red malossi spring and never had issues with anthything like this. I drive with 5.5g rollers🤷♂🤷♂
That's because he mentioned it in the video.. that sr was using way heavier rollers🙃
Please help me, I'm in need of a good reliable scooter and I'm about don't with my scooter. No matter what I do it never cranks well or drives well. It's a 2015 Kymco agility 50cc with 23,000 miles on it. I don't know what to do anymore. It's my daily source of transportatio.
It’s because That’s not a reliable scooter. It has 23000 miles on it
Since this video is about an Sr. It's a Morini engine. These come with an very heavy stock spring an 9r rollers. I've got the problem with the Morini engine, it's perfectly setup 70cc, yasuniR , multivar, delta clutch etc but the top speed won't go above 70khm. Ever had this problem
what's the question?
I have a stock bike with a eBay black exhaust same engine (Suzuki katana) everything what rollers will I need as trying to chase down the previous owners mistakes bc I can only get 33 on speedo and been told that they get to 45
Do you guys sell parts for Honda beat 125cc in the Philippines let me know thanks

my scooter looks like that... with the shavings all over the place. new belt too
Stretch mount for a Honda PCX 150 can you make it ?
ALREADY EXISTS AND PEOPLE DONT REALLY BUY IT
How can I get it ?
I have tried looking every where online even webike is difficult
I've found the belts can do 30,000 miles before they snap. So I plan to change them at 20,000 miles.
we have seen good brand belts go at 3k its all on how hard you ride it
Wow I would love to win that scoot
did you follow the directions to win?
@@Scooterswapshop New to scoot scene I been following you all for while was probably right before I learned about you all. I am going to be ordering me a keychain in hopes to win the new contest.
That's terrible if it was setup by a shop.
The crank puller tool is great to have it you rebuild engines
It sure is
Do you have any Chimera intakes for a 2012 Yamaha BWS 125(Zuma125)? Would be glad if you could help. Much oblige
We can get it for you and have it shipped out email paul@scooterswapshop.com

I’m going to order a sticker pack, can everyone sign the stickers for me? I’d love that.
i change my belt evey 5 miles,, red contra,, maybe thats why,,hehe..
hahah
Do you guys ship?
Of course have you visited our website?
i have seen rollers like that they are just realy worn down so yeah just like you say something is not right
yeah strange but its all great now!
@@Scooterswapshop i love the bike and the thing that stoot out for me was the diffrent older style headlight thats in it we dont got them in the netherlands never seen them
When are you guys restocking dio primary gears 13/35? 🙏🏽🙏🏽🙏🏽
Whats the brand? thats a interesting size you are asking we have 16/36 in stock.
@@Scooterswapshop Honda dio top racing primary gear set 13/35. It’s on the website just bummed they’re sold out.
@@Scooterswapshop trying to pair the 13/35 primary with secondary gears 13x45 to get 9.32:1. I have a dd50 block with dd50 primary gears (12x34) I’ve been hunting and can’t find af16 primary gears (12x42).
When you say size 1500 rpm for clutch or contra springs does that mean soft?
Link doesnt work, hoss. I'd like to contact you, got a website? Or a phone number. Advice on parts, etc.
Hi you copy and paste. I don’t believe TH-cam allows links. It’s scooterswapshop.com
Thanks
These are funny if they were not ripping or off who walk in there shop and clueless
Says the guy with a TH-cam video on a “moon rock”….
Did he say $500 or so to fix this?. That's ridiculous when a brand new scooter is less than $2,000. No repair should cost more than 5% of the total cost of a new scooter. Period!.
Sorry that’s now how it works. That theory doesn’t work at all. So your saying if you buy a $10,000 car, no repair should cost more than $500? I’d love to know which universe this exists in… labor is labor doesn’t matter how old the vehicle is, labor rates aren’t cheaper for cheaper vehicles
@@Scooterswapshop Yep. People have to be paid for their services and expertise. That's part of life. Don't want to pay a plumber $80 an hour then you better learn how to do it yourself. Don't want a high bill at a mechanic shop, then you gotta learn to work on it yourself.
@@CrustyHondas nailed it. I’m an electrician by trade so that sits well with me, pay for it or do it yourself
So not knowing that I need a weight or a spring is a prob, color coding only allows for fakes (ie: spray that one green and send it?) come on and tell us what is what..
What weight? What springs??
I can put a 1500 spring in a clutch and a light roller in there (6 gram) but that is all phopaa...
Same is same...
One thing has everything to do with the other on gearing with cvt...
I have a heavy weight scooter but the clutch is engaging too late so it shifts (3rd gear) up before the clutch engages (then back to 1'st gear) and I if I got ran over by the fool in a v8 car or truck that was in a rush, what would a contra spring mean to me?
Cures for that?
Ramping of the clutch with slinky springs?
Weight of the sliders/rollers? A low (1000) contra spring painted blue?
Let's start at the beginning...
49CC qmb.
Too easy? Impossible with all the double talk out there...
A battery?
Battery be damned.
PS: filled up after a 100 mile ride in less than 30 seconds at a cost (and consumption) of $3.30 Humm...
Pull over for a hour+ to charge your battery? With electric you don't have a spare and have to stay?
I'm a ole Harley fan (been across this country twice. ocean to ocean via bike) and the belt made power, on a 49cc CVT it uses it up via friction.
No real rocket science there...
So a 139 QMB 49cc long case with a 12 inch wheel needs what weight on the Variation?
No need to warrantee it, it's real or it's not.
Time to get real about it.
I think 90+ MPG is WAYYYY better than a dead battery and a ensuing problem in the parking lot while I'm stuck waiting for a hour t0o get charged...
But then what do I know?
Wanna hang around while your transportation get's charged back up from electricity we don't even have to power homes (rolling blackouts)??
Me neither...
A simple thing, roller weights versus sliders?
Gram conversion table?
Real facts??
How complicated.

Help us out...
Im so confused at the paramore lyrics, Also the questions are super confusing. I cant answer 20 questions here your best bet is search each issue and go from there we have SEVERAL CVT videos... start there
@@Scooterswapshop Well I guess I'm asking this...
I have a gron clone (vitacci) came with terrible springs so I bought 100 and 1500 springs hoping to tune it. The clutch is lightyears better but still enguages at 300 rpm (not a bad thing) but the cvt shifts way up and then settles in a low gear 10 to 15 feet from the stop sign (a dead stop).
100 clutch and matched contra blue. Can't go to 1500 on contra as the thing takes forever to shift up and it not using any torque from the motor...
Running around 8k on the tach. continually but no grab on gearing making the motor a zinger at 8k rpm that won't get outta it's own way.
Only 200 miles on it.
Any ideas on parts to fix this? Thinking about converting to a manual flat slide carb and sliders but can't find any stock specs on this china scooter.
Guess I'll have to weigh the rollers.
Any suggestions would be greatly appreciated.
Thanks...
Oh and the paramore was just a good tune to through in...
...nothing meant by it, just like the tune.
Try this one...

Hehehe :-)
Did dude said $800?
sure
Where’s carter?!?
Him and Chris no longer work for us. Happened last spring
Sucks for him! That would be my dream job!! Can I get a application? Lol
@@nastynatesscooters9896 bizarre someone would quit when they get paid to do wheelies and build hayabusa trucks right?
Yes! That would be a dream job!!
yea i dont really fuck with torque springs dude better off just changing the rollers
Two different parts serve two different purposes
These people own a shop can’t believe anything they say here I’m self employed bike and engine building guy there trying scare you too buy shit you might not need for another year of 4 lol 😂 if in doubt take off the screws look at belt if is in bad shape buy one if looks good fuck this bs you can tell just have a look
Cool sorry bro. My guess is you specialize in tao tao’s and icebears. look into spellcheck before trying to tear someone else apart
