Compression spring too weak to keep screw fixed in place
I put this in a week before a race. I was able to adjust the carb so the bike would run correctly. However, there was not enough tension to hold the adjust mentbin place. In my first practice run at the track it unscrewed itself from vibration and fell out. Another rider spotted it because it was red. I reassembled it and held it in place with duct tape.

Almost perfect and a must have.
It would have received 5 stars, however the spring is a little too weak and may have a tendency for the adjustment to move with the right motor vibration. I replaced the spring which firmed it up and solved the problem.

Doesn't fit my carb, but it looked like a nice piece.
I didn't think the cut on the knob was too sharp as others have mentioned and it looked like it would be a direct replacement for my factory screw, however, the thread pitch on this screw does not fit the threading on my carb. The threading on the screw is on the coarse side of the pitch, my factory screw has a fine thread pitch on it, this screw would have destroyed my carb if I had forced it into there. I didn't see this mentioned on any of the other comments, but the screw I purchased from Motion Pro worked perfectly. If it matters, I tried fitting this onto a 2003 YZ450F, but it didn't work for me. According to Amazon, this "will fit my bike" and I'm not going to bother returning it, It may end up fitting another one of my bikes so I'll just hang onto it. Other than the whole not fitting thing, I'm sure this would have worked as it was intended, like I said, It was close, but not quite what I needed.

Great price did the job very sharp edges though
Price was great and it does the job intended well my only downside was that the edges of the part you turn are very sharp so just proceed with caution when adjusting without gloves. I used my original spring as I found the spring with this one a little long. In summary I would definitely order this again if needed for another bike. Happy with it.
