Hello everyone, I'm new to the forum. I have a rebranded Riya Ry50qt-16(Sonic City+), plan on installing a big bore kit and have some questions about the process. What I need from it is faster acceleration and the ability to cruise at 60-65km/h. From what I've read most people recommend a 70cc(47mm) big bore kit, a bigger main jet, different weight rollers and bigger variator belt. There's one for sale, the seller claims its 80cc with a 47mm bore. The stock carb is a PD19J, and there aren't any bigger jets available for it. Some scooters have the PD18J, since this one is bigger would it work fine with the BBK or is the bigger main jet really necessary? What's the stock weight of the rollers and how lighter or heavier should they be for a 65-70kg person? After installing the BBK, how long should the break in period be and how should it be done?
Thanks.
Thanks.
