Upgrading my Yamaha Aerox 50cc 2012

I have just bought an Aerox as a project for fun and would appreciate some guidance on how to make it go better, it is completely original as far as I am aware, I want to upgrade it so that it will go a little faster but not necessary raucous, something along the lines of fast acceleration up to 70 MPH perhaps, what should I start with?

70mph is a lot to ask for... Maybe you'd be better off buying a good 125cc scooter and working on that as a project to get around those speeds .

 

Thank you Ok, what would a realistic figure be if I changed the rollers, exhaust, carb, Cylinder, that kind of thing,
here she is

 

With just bolt on parts like those you have mentioned you should be able to achieve 65mph give or take a few figures

 

How much did you pay for that? what year is it

 

What should I begin with to start seeing a difference which will match other components later on?

 

get a decent exhaust, best thing to do first! Would go with a 70cc kit after that

 

Can a 100cc cylinder be fitted to this bike, what is the biggest I can change it to?

One more thing, am I in the right section, should I be in scooter projects?

 

a 100cc head wouldnt fit

 

a good 50cc set up is a motoforce topend and crank and a leo-vince zxr and a stage 6 variator as my mates keep up with a 125cc yamaha xt125 till 55mph and i think it gets about 65mph on his speedo so id say it dosr 60mph

 

not a 100cc, but there are big bore kits that go up to about 94cc you can get, but they require a different crankshaft and case work

 

Streetrace 70cc, stage 6 pro rep exhaust, 17.5mm carb, malossi multivar is what i have on mine sits at 60mph easy. I'd change the crank to a performance one to be sure, if you want anything over 70cc case work will have to be done (i think!). Or maybe look into swapping the whole engine to a 100cc aerox, but i think everyone rates 100cc's as shit.

Good luck

 

Surely a standard 100cc engine is better than a tuned 50 /70 engine dunno how people can rate them as shit

 

No the 100cc aerox engines are shit they are air cooled. Shit for tuning and not as fast as a tuned 70

 

fair do's yeh i know what u mean about air cooled engines n tuning them i had a trekker 50 (pug) n put a new crank in it an balanced it along with a motoforce 70 kit and gear up kit with a 21mm dellorto carb and zx pipe n was pritty shit outcome tbh where as someone who did a speedfight 2 lc got more from it ( speedfights and trekkers have same engines pretty much )

 

All peugeot 50cc 2T air cooled engine are the same and theyre shit but the liquid cooled ones are actually half decent but dont even compart to the likes of a runner/aerox etc

 

I was told to put in a sito plus standard exhaust on and a 68 jet in my gurtner carb, and go from there

 

That sounds like your standard setup

 

I think that was the idea, to put it back to a standard setup to find out what was wrong and go from there.

Can you tell me how to open the clutch pulleys so that I can get the vairiator belt on, please see picture.

 

Providing your contra spring isn't to stiff you can pull them a little with your hands and then prize it over the boss
