I do have comfidence to work on it myself as i'm mechanically inclined and have a long history with cars. The only thing that i dont know is how to adjust the fuel ratio....

Secondly what do you mean by transmission service? do you mean just change the fluid inside? if so, i can definitly do that....

OK, Cool.

By transmission, I mean the variator on the front pully, that controls the diameter of the front pully, there by "changing the ratio" automatically, the rollers are moved out at high rpm, in at lower rpm (centrifugally)......that is how you get a "constantly variable transmission"

There is a clutch on the rear pully, but that is just to enable you to to sit at the lights (a true "automatic clutch", and again, in to is "centrifugally operated".

You will need to remove the cover of the transmission (pretty easy to see), remove the front nut (that holds the variator cover) and remove the rollers, and replace if need be.

I seriously suggest you use OEM parts, unless you can find a web site that can recommend a better weight set of rollers, because the weights are very important, as they control what RPM each "ratio" is applied, and you could end up going backwards.

If you spent a bit of time sifting through the (most often incorrect) information you will find on the web, I am 100% certain you will find a sight that gives detailed instructions on how to do this...... pretty much every single CVT operated in the same manner, be it Aprilia,Honda,Suzuki,Yamaha,Gilera or what ever.

sweet as... do you know where i can find OEM rollers? the ones at scootling seem to be some aftermarket ones which you did not recommend :S

how do you know if the rollers are bad? i can chuck up some photos if you want of them

worn rollers would effect it all the time rather then just when it is cold...

it is good maintence though. change the rollers, belt and all fluids for piec of mind. piece of piss bro.

OEM (original equipment manufacturer), means "at your local dealer", but, they are not always available, and truth be told, quite often they are quite expensive, but you can always be assured of quality.

Speak to someone like "scootling", I have never dealt with them, but they seem to carry a good range of spares.

Perhaps if you did some research, you may find that an aftermarket company produces ones with a better weight, that offers performance advantages...... scooters made for E3 complaince have emissions standards too meet, after market don't.

No they don't....they affect more hot than when cold.

Plastic expands at a different rate to aluminium.

At 6000KMS your bike is telling you to give it a full service. Your rollers will be getting tired and the three sliders will probably need replacing, the belt could be getting thinner, the clutch could be getting glazed from holding it on a hill, the the rear driven pulley needs lube so it doesn't bog the scoot down (power off then on). the gearbox oil needs new oil, you need a new plug, air filter cleaned, retune then the extras come in if your fussy like cable lubes and anything hinge or pivoting getting lube etc... after all the standard maintenance is done then start worrying about what's not working, you will probably find its like new again.
Most standard maintenance is easy and can be done at home like lubing joints and cables, filters and oil. The variator isnt hard either but get a strap wrench rather than using a rattle gun to take the centre nut off. The cover on the variator will probably have different length bolts so push them through some cardboard to keep the order.
Plenty of info on youtube.

Yes, plastic does expand at a different rate then aluminimum - I won't argue with that.

So what exactly is your point?
