Today I got it licensed so I could ride it legally. Highest recorded speed by Endomondo on my Iphone was 88 kph/55MPH
I think it's running lean at WOT, but cleaning the carb and raising the needle all the way helped a lot at intermediate throttle openings.
I closed the four ½" holes some precious owner made in the air filter box, which only contained a flat metal plate with a metal screen.
QUESTION: Where can I find a service manual for this Zongshen ZS125-47, to determine how the filter is supposed to look?
I've found the airbox on TaoBao, but what's supposed to be inside?
