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

Fit and finish was great! I put mine in a Trailmaster 150x buggy/kart blazer. I highly recommend getting a Vlave adjustment tool. Makes work a lot easier. At first glance, the camera does not differ much from the series. What has changed is the valve lift duration. The performance was very noticeable. I live at 4500 feet above sea level. I drove about 6 km/h downhill and over 10 km/h uphill. Flat surface about 4 miles per hour. What's really cool is that the surge was everywhere. Low level, high level, medium range! The best single update I've done. I had to fiddle around a bit with the idle. But it's easy! Be sure to inspect all surfaces of the cam prior to installation. Do not install one that has bumps on the cam lobes. Mine was perfect!
