Review on Glixal ATKS-030 GY6 125cc 150cc High Performance A9 Camshaft: Boost Your Scooter, Moped, or ATV's Power! by Khaled Ribeiro

Took a risk with this A9 camera and didn't regret it. I have a gy6 150cc with an NCY 172cc cylinder set, NCY Big Valves 58.5 cylinder head and was noticeably lacking in power before this cam was fitted. It was the missing piece of the puzzle. A+ recommended. About a year later, after a small dose of nitrous oxide, the bearings began to turn. I don't think the camera could stand the heat. Went with an upgraded Taida chamber for durability. In the near future there will be no more laughing gas.
