Date Added: 10/29/20096-Pin CDI for GY6 50cc,125cc & 150cc Scooters(Mopeds), ATVs & Go Karts Well it's been awhile and I have worked on many bikes since then, but I do remember the part because it was my scooter. It was cheap enough and easy to install and the shipping was pretty fast. I am still riding the scooter.
