This is a pretty good upgrade for the money. It made the bike start easier and increased the top end speed by 7 mph. The bolts it comes with were not long enough and very cheap. I used some extras I had lying around.

Installed on 125cc pitbike and it gave it a little more oomph. I've still got to get the right jets but it runs fine as is. The a/f mixture screw is on the bottom and you need to remove the carb to set it.
