Glixal ATKS-030 GY6 125cc 150cc High Performance A9 Camshaft 152QMI 157QMJ Scooter Moped ATV

Changed cam, head and rocker assembly. Have a significant DECREASE in over all power with this cam for my particular 150cc scooter. My stock cam was much better. Also a ton of lifter noise. Tried multiple valve settings. Appears to be a 50/50 on here if this will improve your power or not depending upon your stock cam. Still getting 5 stars, the parts are all top notch stuff and fit perfectly.

Adds very noticeable instant rev power. Be sure to adjust your valves after running for a while, because it will break them loose and click.

good purchase but you will probably need to rejet and tune. get an oil breather if you have an old model or you will be blowing seals all over the place

Took a chance with this A9 cam and have no regrets. I have a gy6 150cc with a NCY 172cc cylinder kit, NCY Big Valves 58.5 Cylinder Head and prior to installing this cam performance was noticably lacking. This was the missing piece of the puzzle. A+ Recommended.About a year later, and after a small shot of nitrous, the bearings spun. I guess the cam couldn’t take the heat. Went with an overpriced Taida cam for durability. No more nitrous anytime soon.

Fit and finish was great! I put mine in a trailmaster blazer 150x buggy/gokart. Seriously reccomend getting the vlave adjustment tool. Makes the job so much easier. Upon first look the cam doesn't look much diff from stock. What changed is the duration of valve lift. Performance was very noticable. I live a 4500feet above sea level. I gained about 6mph downhill and over 10mph uphill. Flat ground about 4mph gain. What is super cool is the gain was allover. Low end, high end, mid range! Single best upgrade I have done. Needed to monkey with the idle a bit. But that's easy! Be sure to inspect all surfaces of cam before install. Dont install one that has irregularities on the cam lobes. Mine was perfect!
