I picked up a scooter about a month ago and decided to do a build log.
The motor started off as a stock 157qmj gy6 150 cc.
Taida 61mm bore kit
Taida T300 race cam
Ncy 61mm big valve head 28/23 valves
D Star performance exhaust
Nibbi Intake manifold
Keihin cvk-26 carb
Dr. Pulley 13g sliders
I ordered all of my parts from Martin mopeds.
