I had to open up the small holes and the large holes to get it to fit my grandsons Monster Moto MM-K80 kart. The bolts weren't the correct size either. It does work now though.

This sprocket was intended for the coleman CT/ baja db30 variants, the holes dont line up so you would have to grind the holes a few millimeters bigger for it to fit. After that had no problems

To start off, the holes didn’t line up to my CT-100u but not a big deal. Second, after the first ride the teeth started to wear down. I know there is supposed to be a little, but this was just crazy. It looked as if the sprocket has been through a thousand miles after its first ride.
