Everything in this video is top quality. The cam in the video, is in fact a performance cam. If you want low quality junk I can sell that to. We have have good stuff and the cheap stuff like you see on Ebay. You decide what you want to buy. Remember you pay for what you get.

nice kit, without a carb to put out the fuel needed to support that exhaust/bigbore. Gg.

Не в Обиду но меня всегда удевляет когда в США, закупают все блестящие и красивое .. не всегда что красиво это деньги выброшены можно так сказать ...

cdi swap will only make a difference if you upgrade to higher cc you should tell people this. if you just buy a new cdi for a 50cc it will not do anything but make it harder to start the scooter no matter the cdi excep the stock will make it ezer to start this is do to the fact that the non stock cdi are limit less for starting starting and take off rpms they are higher and that is not good for a 50cc but with a bigbor kit its good to have and if you rejet the carb it can help to
