Best Yamaha Aerox Sports Exhausts.

[Mike.Aerox]

Hi, I have a yamaha Aerox 09 plate and i have had the washer in the variator removed. Now i want new rollers, Clutch springs and a sports exhaust but i dont know what one to go for. I am looking at the £120 range and have found 3 which i am stuck on deciding. The yasuni, The gianelli, or the Leo vince ZX. I want the one that sounds the best but also gives the most preformance to the bike.

Any help would be appreciated.

Thanks, mike

Unless you are planning on getting a cylinder kit and cdi with no rev limiter stick with stock if it's a catalysed model get an older non cat stock exhaust.

most of the sports pipes produce max bhp at rpm's that the stock cylinder and cdi just cant handle, most sports exhaust need the engine at 12-14krpm+ to get the most out of them, as you can imagine this will reduce reliability and will need a heavy duty crank etc.

That said the zx is a lower revving pipe than most at about 8-9krpm but the bike will need everything else setting up after just to get the scoot ridable again.

Got to agree with Prawny - I would just be happy with the washer out and a standard looking exhaust. I have a Piaggio Zip 50 that i'm selling that only has the washer removed and a Technigas silent derestricted exhaust fitted and and is doing 45 - 50 Mph indicated. I can leave everything else standard and the mixture is right as a plug chop demonstrated.

I don't know how old you are or licence quals etc but you are entering a whole world of trouble once you start doing that kind of modding. Do you honestly think traffic cops don't know what a expansion chamber exhaust is and if your doing 50 mph then it's pretty obvious.

My set up gets OK speed and looks standard = less hassle. Not that it matters as I have a full licence and mods disclosed.

so say ifi was going to get the Leo vince ZX, what would i have to do t make it run smoother and how fast would it be able to go ?

[prawny1]

[Livefast123]

It's not about making it run smoother, it's about getting the mixture right so you don't blow the engine up.

With the ZX pipe you'll need to upjet the main jet to a bigger jet and fit lighter rollers. I wouldn't bother with the clutch springs unless the original ones wern't doing their job.

I would imagine you'll be seeing 45 - 50

What was said i the above was really helpful. If i get the ZX exhaust what exactly will i need to change and what to? what is te top speed of that when it has been completely chenge? and Does the final peice sound nice?

[SpannerMonkey]

[Mike.Aerox]

If i got the ZX and done the rolers and new clutch springs would that make a difference?

[SpannerMonkey]

[Mike.Aerox]

I have currently got the washer out of the variator removed and the bike runs smoothly at 40mph. If i bought the ZX and put it on without making any more modifications what would happen to the bike then?

[SpannerMonkey]

If you fit the ZX but no rollers or clutch springs or upjet?
First of all without the rollers you'll be running outside your power-band so your bike will be slower than standard. Without the clutch springs, you'll be taking off WAAAAY outside any useable torque... and without the upjet, you'll run very lean and run the risk of destroying your engine.

So if i fitted the ZX and upjet it, what would happen then?

[SpannerMonkey]

Exactly as mentioned above, just without the running lean.
Sorry to be blunt here, but pay attention to what I'm saying, the answers are in there. I understand that you want to double check everything

And basically, if you fit the ZX without fitting the other bits, you'll sit below the powerband for ages and have less power than normal UNTIL... you run out of gearing on your variator and it decides to move up the rev range a lil. but that wont happen till 45-50mph-ish

I know sorry for askin stupid questions, but im not allowed anythin else done apart from the sports exhaust so i want it about 45-50 thats all but dont want to do anythin i dont know what it is becuase i dont want to ruin the bike and i need to make sure everything i am doing is right for the bike.

[SpannerMonkey]

[Mike.Aerox]

no its my dad. i have 400 to spend, but im lookin around the 120 pound mark for the exhaust. i have found a zx brand new with rollers and cluth springs included for 120. then alls i would need are the new jets. I am getting the sports exhaust but modifying it slowly i think but what ever you reccomend is best is what i will do.

[Nope.]

To be honest, unless you intend on keeping the bike for years to come and are happy doing top end rebuilds fairly often (More then stock anyway) then I wouldn't bother.

You'll get little gain from a lot of money. Id put that 400 towards a 125 next year or towards your bike test and a bigger bike.

If, however, you really badly want to tune your aerox, then theres no point just fitting a sports exhaust. You need to go the whole hulk and kit a 70 kit with a decent Yasuni system and malossi/polini parts which will take up your £400 budget nicely.

If you don't want to do that, and you intend on just fitting a sports exhaust (for some reason..) then I would go with the Yasuni. The Leo Vince ZX isn't the best exhaust and is restricted internally as well as in the down pipe limiting its potential as a decent pipe. The yasuni exhausts have 2 different restrictions, the first being in the down pipe and the second being in the silencer. I can find pictures if need be.

With any sports exhaust (and even the stock exhaust derestricted) you need to upjet (otherwise the engine will seize), change the rollers and change the clutch springs else it will probably end up worse then stock and you risk damaging the bike.

Im sure you know this, but just remember, if your 16 your riding otherwise then in accordance with your licence and therefore risk loosing your licence (3 points otherwise then in accordance, either 3 points for no insurance or 3 points miss declaration of a vehicle or something similar) so in total you could end up with 9 points and on a provisional its 6 points and your banned. Do you really want a driving ban this early in your driving/riding career? You also risk having the bike confiscated and crushed. Don't think the cops are stupid, they know what a fancy expansion pipe is and a lot of forces have mobile dyno's now a days which means your screwed if they see you doing above 30.

Whatever you choose, good luck too you.


EDIT:

Yes Jets are brass (Usually)

What If i fitted the leo ZX and ne rollers which will come with it and clutch springs which will also come with it and new jets, but put a washer in the variator to restrict it back to around 45mph by fitting a custom washer.

Also i could take the leo vince zx new rollers and clutch springs to a bike shop near my house and they can fit everything properly and find the right jets for me and derestrict the exhuast properly for £30

My dad has said i can have what i want done but he wants me to have a top speed of about 45-50mph some how.
Any suggestions on how to do this?

[Mike.Aerox]

My bike is a aerox and its brand new i love it and dont want another one, the only problem is it runs to slow, i could get the bike upto about 60 mph but not allowed that yet.

[prawny1]

If the bike is new then don't touch it yourself "you will void your warranty",

Get the dealer to derestict it for you they will set the bike up properly and will know the correct jets to use etc this will be good for the 45mph top speed your after and you won't need to buy any shite exhausts or anything and because the work has been done by a dealer the warranty will be intact.

Some dealers will only derestrict bikes if you can prove you are over 16 so you may need your dad to take it in,

You have to understand that derestricting your scooter is enough to get it's full designed speed, sports exhausts and all that are intended to increase top speed not derestrict the bike.

I have done some research and i think i have found the answer, but not sure if it will work,

If i fit the leo vince ZX and the correct rollers, correct jets and clutch springs, and tune it fully and get the exhaust fully derestriced to get the maxium performance out of the bike, then find the right size washer for the variator so it can stop at 45, if the washer is too thin take it out and get a thicker one,,, if this works then i have my problems solved becuase alls i want will be done and the speed is right for my dad.

[Nope.]

F**K's sake. You really don't listen do you.

I hate it when people come on here in the hope that they will get approval for there hair brained ideas. So here it is:

'Yeah that's a great idea. Are you a genius or something?'

Back to reality.

The washer in the variator works by limiting the amount that the vario halves can come together thereby stopping the belt riding up and stopping the bike going into the higher gear ratios.

I doubt you will be able to find the right place on the variator to fit the suitable washer to restrict it to 45. If you did manage too, it would be utterly pointless. Either fit the exhaust, do the jetting, rollers and clutch springs or dont bother. At the end of the day, it comes down too you, but at the moment your playing silly buggers with it.

If you derestrict the stock exhaust, upjet and do the clutch springs you will probably only see about 40-45 which would fit your needs perfectly. Do that as opposed to fitting a sports exhaust which is obvious to the cops and will cost you more then 5mph is worth.

Listen to whats being said here, a lot of us have been and done this so our advice comes from experience as opposed to the black and white vision of youth (Even though I still have that...)
