Mod for mini bike
I bought this for the mini bike to increase the acceleration and speed it does both because I'm getting more rotations out of my tire for the car that's on the engine more or less about the same because I'm getting a straight one from one where it was a little lower but this definitely gets quite a bit more speed. I just haven't done a test of how many miles per hour it goes up Max I'm thinking around like so far 40 miles per hour on the 99cc.

Not enough description.
This is #40B pitch sprocket. And it has 2 set screws but nowhere in the description does it mention that #40B is wider than regular #40 go-kart/mini bike chain. So I get to grind off 1/16 off Each side..
