Review: Very satisfied with this purchase - At first I was kind of skeptical because there are so many different sellers stating that their camshaft for the gy6 139 qmb is a A9 camshaft other sellers selling it for more or slightly less there's other brands that cost several times the price of this one I install this on my moped with a Big Bore Kit 47 mm which is the best for reliability and improve power without damaging the bottom end and allowing you to Rev this camshaft me and my bike sound more like a motorcycle not that it's aggressive but it's more powerful in the mid-range on up and it does the whole dash now it performs great I would buy it again and recommend it to others just make sure when you're installing it you're watching videos on YouTube first you might see the riding on there that says but the writing is supposed to be upside down and you're supposed to line up to two smaller holes on the left and right side with the slightly larger hole at the top to set the timing and make sure that the flywheel is lined up with the T so it's at top dead center or you will damage your engine

## Questions & Answers

**Q: Will this help my 72kit tappets touch**
A: Yes it will

**Q: Cannot seem to get rocker arms close enough to set gap on 100cc upgrade. Valves are noticeably shorter than stock. Whats wrong?**
A: Wrong size head, A9 cams are for the gy-6 139qmb 50cc-  100cc big bore kits. You may have the long valves and you need the 64mms length not 67-69mm

**Q: Will this help my 72kit tappets touch**
A: Not sure what you mean by helping your rappers but this cam will make a bit of a difference in your performance by letting more air into the mix and better exhaust flow.

**Q: Will this work for 69mm valves?**
A: It will work on any engine up to a 150cc then I believe it is a A-12 cam

### ⭐⭐⭐⭐⭐ The ultimate street cam.
*by R***. on April 21, 2016*

Very good canshaft, its probably one of the best camshaft profiles, and cam characteristics for a street bike. Hotter cams usually sacrifices bottom end, but this cam is very close to an original cam on the bottom RPM and you may find small differences if you put the engine in a dynamometer, but for day to day driving I would say that the bottom end is the same. The benefit with this cam is that it doesn't run out if breath but continue to go strong and pulls with very good authority on higher RPMs. Most installations is bolt on, but the cam has a bit higher lift, and you have to check for coil binding and valve clearance. Turn the engine by hand over a few times and check for bind, if no valve contact or coilbinding, youre good to go, its ordinary routine when installing a cam, and should pose no problems. I have used this cam on both small and big valve heads and for me so far, it has been a straight bolt on.
