A lot of people complain about the noise of the Malossi gear-up kit,due to the gear teeth being straight cut. PN Planning are selling both primary and secondary gear-up kits with helical gears(for the Aerox 100,but maybe for other makes,I haven't checked). I just ordered my PN Planning p&s gear-up kits from Webike Japan. They are a lot cheaper than Malossi,also. If their gear kits are as high quality as their 9-port,alloy big-bore kits,I'll be totally happy.
That's a great explanation of how to work out the gearing. For a rough idea of the final drive you can mark the clutch bell, and tyre. Then see how many turns of the clutch it takes for the wheel to turn once.
that was good, i just went from a 125 to a 171 piston,need to do the calculations now to order parts; the previthey are new, may keep them,have to account for that too i guess the first thing is to open my gear box,count teeth and go from there? it's a Shenke(same as Jonway )125
I'm thinking of upgrading my 80cc to a 150cc plus maybe 180cc or something along those lines however I primarily want to increase the top end by installing a smaller final gear but no one is able to tell me what the max size that fits in the case and will the scooter be highway worthy? For some reason no one in the scooter community cares about the highway.
The parts manufacturers have a range of set gears so you are limited as to what you can fit. Look at the available gears for your scooter and go from there. Compare what you currently have and gear up accordingly.

We didn't get the MC2 in Australia, only the later model NRG in limited numbers, so I couldn't give you specific advice on the exact kit to use - but I'd recommend increasing around 15% if its a basic sport cylinder kit and sport/street exhaust. Count your factory teeth, use the ratio calculation and then plug in some Malossi or Polini options to work out which is going to give you the increase you're looking for. We have an article on our website (link in video description) which also shows how to work out the ratio, you can just substitute in your teeth numbers.

Hey, I have a few questions. I have a 50cc gilera runner upgraded to a 70cc MHR cast iron cylinder. I recently changed the gearing from 1:13 to 1:11 by changing the primary gears. I gained 10km/h but it bogs down at that speed and it also screams alot (the variator rollers are 7,6g). Do you have any advice?
The straight cut gears do make a turbo noise at high speed, is this what you mean Screams? Also try to retune the carby jet. Booging may mean you need the next jet size. Do the pen test adn make sure the belt hits to top position in the Variator.
@@zekzygaming5128 Ok ok, try heavier rollers, BUT you need to do the Pen test first and then go heavier by small increments. If it is reaching the top then you may consider the secondary gear kit. You could also up the rear tyre size.
Привет, приятель, как дела? Если коленвал и подшипники не изношены, то все в порядке. Если вы сомневаетесь, что коленчатый вал в хорошем состоянии, то да, его необходимо заменить. Установите новый кривошип, подшипники и уплотнения.

@@curlschannel7379 Find out what is compatible for the model and then go for the race cylinder and exhaust, we do not have a Vento in Australia ( possibly rebadged as something else) but it looks like a Minarelli based engine so go down that track. What part Brands have you previously fitted?
@@scooterstreetau yes minarelli, it’s a QMB40 if i’m not mistaking it’s the long case, it was completely stock, and i miss typed something it has a 28 mikuni carb, kinda big but it rips, anyways it was completely stock then i added those parts like a 72 polini kit and exhaust,, the variator is also polini i think i’m running on 6g rollers right now,, with a hard spring on the clutch, i’ve also realized people have there pulley belts loose, is that how it’s supposed to be? because mine is on pretty tight,, i can’t get it on the variator unless i open the clutch a bit, is that good?
has the stock 16/49 primary gear and i added a stage6 15/39 secondary, for top speed, it raised up to maybe 56mph let’s say 60, i know it goes faster because i’ve seen a honda elite 72cc go 79mph and that’s where i want to get at, i don’t what there setup or gears look like though
Which exhaust did you fit? If you have fit a performance exhaust the engine will move slowly from the start UNTIL you make adjustments and parts changes too the main jet, the rollers and the clutch spring..👍

I gained 10km/h but it bogs down at that speed and it also screams alot (the variator rollers are 7,6g).
Do you have any advice?
The straight cut gears do make a turbo noise at high speed, is this what you mean Screams?
Also try to retune the carby jet. Booging may mean you need the next jet size. Do the pen test adn make sure the belt hits to top position in the Variator.
@@scooterstreetau ow yes, I love the turbo sound but with screaming I mean that it's revving too much
@@zekzygaming5128 Ok ok, try heavier rollers, BUT you need to do the Pen test first and then go heavier by small increments. If it is reaching the top then you may consider the secondary gear kit. You could also up the rear tyre size.
@@scooterstreetau yes I'll try the pen test first. Thank you very much mate
@@zekzygaming5128 Good idea👌 Very welcome.
What Do yo think about a yasuni carrera 10 , is a 19 mm good?
Are these gears or exhausts? Carbys?
@@scooterstreetau Yasuni carrera 10 is a exhaust,and the 19mm is a carb
@@xaff4414 Yasuni produce very good products so I would say the parts you mention would be of good quality.
Скажи пажалуста. Я хочу паставить 70куб целиндор на sr50r. 2t карб. Каленвал выдержит?
Привет, приятель, как дела?
Если коленвал и подшипники не изношены, то все в порядке. Если вы сомневаетесь, что коленчатый вал в хорошем состоянии, то да, его необходимо заменить. Установите новый кривошип, подшипники и уплотнения.
@@scooterstreetau огромное вам спосиба и за ваш труд и профессионализм. Вы человек от бога.
@@serzikpetrov9391 Так мило с твоей стороны, спасибо тебе большое, друг.
Always very helpful!! I was wondering what you guys think about adding a gear up kit to my piaggio zip 2t. Has got the malossi sport 70cc kit with TT vince exhaust and malossi multivar 2000. Do you think putting the malossi 15/38 gear kit would do any good ? Thank you
Thankyou and yes that's a great idea! Or a 14/47 secondary.
@@scooterstreetau Thank you for replying. What do you think about the malossi 16/37 gearup kit ?
@@ST-9788 Calculate the gearing as in the video before fitting that one.
hi what would be some good gear for a 70cc polini 2 stroke vento so i can get up to those 80mph number, i have a pretty good decent setup i’d say, i have the big bore kid with polini exhaust, polini variator and malossi clutch, 21 keinhen carb,, coil and cdi only thing stock in crank and magnet,
You would consider going to a higher class (race type) cylinder and exhaust and upgrade the gearing too.
@@scooterstreetau okay,, what do you recommend?
@@curlschannel7379 Find out what is compatible for the model and then go for the race cylinder and exhaust, we do not have a Vento in Australia ( possibly rebadged as something else) but it looks like a Minarelli based engine so go down that track. What part Brands have you previously fitted?
@@scooterstreetau yes minarelli, it’s a QMB40 if i’m not mistaking it’s the long case, it was completely stock, and i miss typed something it has a 28 mikuni carb, kinda big but it rips, anyways it was completely stock then i added those parts like a 72 polini kit and exhaust,, the variator is also polini i think i’m running on 6g rollers right now,, with a hard spring on the clutch, i’ve also realized people have there pulley belts loose, is that how it’s supposed to be? because mine is on pretty tight,, i can’t get it on the variator unless i open the clutch a bit, is that good?
has the stock 16/49 primary gear and i added a stage6 15/39 secondary, for top speed, it raised up to maybe 56mph let’s say 60, i know it goes faster because i’ve seen a honda elite 72cc go 79mph and that’s where i want to get at, i don’t what there setup or gears look like though
Hi,i have an Aerox,just replace the stock exhaust and first gear slowly move after revs,when i put the stock back first gear revs,what îs the problem?
Which exhaust did you fit? If you have fit a performance exhaust the engine will move slowly from the start UNTIL you make adjustments and parts changes too the main jet, the rollers and the clutch spring..👍
@@scooterstreetau i put leovince TT
@@B58-555 Did you tune the engine? see previous reply.
@@scooterstreetau no,its original 50cc
I change the mein jet 72 up to 85 now its move From the start,But 85 its not big for 50cc?
14:39 is faster top speed than 14:46. Hi you claim that it would result in a slower top speed ! Savi English man from the state's ?
Can help me please?
?
lol broused the comments & so many people are link F the math just tell me! Also probably just a aussie term but its not a diff - as in a differential. If anything its a gearbox.
