    From other posts I've read, the cheap Chinese ones are just that! If you care about your scoot, best go for the high quality ones. If you go for a cheap one and it breaks, it could break other important parts.

    ^^ perfect timing ^^

    i agree 100%

    the answer is in the detail of the small parts quality or quality control. I saw a garbage one where the entire slide assembly was a disaster. To bad, better luck next time... not something that would be obvious either.

    Mostly the problems would be things like reed valve, carb and specifically the jets and atomizers need to be cleaned. Finally and air cleaner unit maybe no longer matches the needle on the carb. The Doppler filter I suggest is pretty close to what is needed on the 17.5 carb because it has a 17.5mm tube. Likely lose a bit of low end in favour of topend but show me something better...

    perhaps the doppler filter and vforce should be you first purchase if performance is your primary goal.

    Correct site but negative on both items.

    -The topperformances 8 reed valve

    -The Doppler Filter with the mesh top not the dome top. And I must warn you it fits piaggio perfectly but the other engines need to be mounted with custom tubing from the stock air box or something.

    That’s correct yes, I like all the colours except the silver myself. I believe it will drop in yes. I keep saying that thou and people have issues with the shock location or something. Mine it fits like a glove. It is absolutely worth it to get it to work. It sounds nice a low and snarly standing beside the bike. From a ways down the street it sounds healthy and stock.

    Try not to run lighter than 6.5g

    7.2g is better and 7.5 is better still if you run well enough to pull it.

    The valve will bring more power so if anything you might want heavier ones if you could pull them. Likely not till 70cc.

    Naraku 4k clutch would be a good purchase. As would the malossi 5k clutch if you like high performance pipes
