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

Not much noticeable power gain out of the corner but my scooter seems to handle the last part of the cap a bit better. I no longer have to grab to get from 45 to 50 mph. What you'll notice, if anything, is that it might have felt a little sluggish before, not anymore. Smooth throughout the rev range. In any case, it is VERY worth the price and the time it takes to install.
