Post 70cc bbk
I'm getting ready to order my big bore kit. I'm still debating if I should go all the way and do the Athena crank at the same time with the bigger wrist pin or just do the 70cc kit with the stock crank. I really don't want a super loud pipe. I don't mind it being louder than stock but I don't want it ridiculous loud. Seems like a lot of people are running the 70cc with stock pipe and having ok luck. I would like to get it to run 45 comfortably and not slow down so much on a grade. I'm assuming I will need a pipe to get the extra rpm but still trying to research one that's not crazy loud. Nobody around here hops up scooters that I know of so getting to hear one is probably not going to happen.

I just finished putting on a malossi BBK with a multivar, white spring and 7 gram weights, used the stock carb, currently with 84 jet....... Acceleration is great, speed yesterday was 45ish with one 50 mph run, but I'm not sure I want to trust the GPS on that one... I too don't want noise and so far used the wild lion pipe which is close to stock... This setup may give you what you are looking for....

Yeah I decided to swap in a gy6 150 instead. It is plenty enough power and quiet. I don't have it fully broken in but I will run 50 very easy. I wanted to stick with the original motor but this was more affordable , quieter and just as fast or maybe faster
