what is the best way to improve the speed, horsepower of your scooter

[Rebel]

How much speed do you want?

A 50 that goes 45 is doing pretty well for a four stroke 50cc. There is a saying, the faster you go, the faster you blow. But if you want to get some more pep out of it you should first, in my opinion, tune the variator. By that I mean change the weights in it and see how you like it.

Little motors make power by revving higher, lighter weights let it rev higher, gives you better throttle response, and does not cost a lot of money.

A next step would be to open up the intake and exhaust letting it breath better(after market air cleaner and grinding out bottle necks in the exhaust, ported and polished head), doing this means you also have to tune the carb for the higher air flow, put a bigger jet in it so it flows more gas too. If you don't balance out the air/fuel mixture you will burn the valves.

Most scooters now do not have rev limited CDI's, the electronic ignition module, but if it is limited you need to get a unlimited one.

Big bore kit, a bigger piston makes more power, you can put a 72cc or even a little bigger big bore kit in it.

After spending about $300-$400 dollars on parts and a lot of time doing it, you will still be lucky to get it over 50-55 mph. The reason is because you simply will be limited by the RPM's and gear ratio, it will get there faster and it will climb hills better

I'm all for a person playing with their scooter, but you have to know where it can go and not expect more. I'd highly recommend tuning the variator, perhaps even spending the money for a racing variator. Going further in my opinion is for the hard core 50cc enthusiast.

For practicality, if you want it to run like a 150cc, buy a 150cc it is a lot easier and the cost might actually be less, then you have a 150 to tune too.

Hey, if your TAO TAO 50 is a 2011 model you already have a 63cc engine.....gps it and you will see that you should get 42 - 43 mph on flat surface.......In my opinion, if you use this for your only transportation like I do right now... wouldn't mess around with it....got 5200 km on my Tao and it still runs great.....have had to do valve job and replace back bearing but I live on the beach so the bearing I can understand.....Thanks Kell

[Rebel]

yup a few of these chinese scooters actually come with a bit of a big bore, making them a better performer out of the box. If yours is one of those, then just tune the variator and see if it makes you happy.

my spedometer for my tao tao t3 just stopped work while i was driving, and idea on how to fix it?

[Rebel]

Have you checked it out at all? It may need a new cable, or it could be the gear at the hub.

i have noticed a problem with these they tend to come loose under the instrument panel blue lock tite is good

Thanks every one for the replys I might try the big bore kit

The thing about these scooters is that a BBK won't really make it a whole lot faster. They make it quicker. The BBK adds torque and power but the red-line RPM and the gearing in the rear end remains the same so you get up to speed faster but that top speed really doesn't increase that much. Maybe a few MPH. The added torque helps when climbing grades or riding into a strong headwind though. Don't expect 55-60 MPH cause that ain't gonna happen.

[jmkjr72]

thats the down side to a 4 stroke
but then again if you get the torque up you can regear the scoot for top speed (im guessing that the qmbs have gear options like the hm 2 strokes)

[Rebel]

There are some gears out there, someplace. I've read of people changing them out. I think you'll be able to get them through Enviromoto if you ask him to find them for you.

RocketDog probably knows where to find them too, he has probably changed the gears in his 50cc drag scooter.

I'd highly suggest a big bore kit before putting new gear sets in a 50. Also you do get a little more top end with the right performance variator because it too changes the finally drive gear ratio.

Jeremy did have some on his web page;

Scrappy has some cheap ones, look way down the page;

I use Enviros Stage 6 gears. Before you go with that you might try and fit a larger rear tire. I'm running a 100 90/10 on my short case 139 but a larger one might fit. It's half the price of gears and achieves the same results.

90GT has a great list of sizes and even an article of what fits a short case. I won't link cause GT might not appreciate it but look
at his site 49ccScoot under tec library/wheel and tire tec.

I think you have to be a member to view his tech library, so a link might not be useful.

if you get crazy insane-o-frustrated, you can do a 150cc swap. good for what ails ya! or a 2t swap, those can really hustle too.
