Tool works great as advertised. The only problem is that the 3mm square driver sticks out too far and can't get to the exhaust valve bottleneck on my 2021 Honda SuperCub C125A. I had to remove the fairing and air intake to get there with him. I had to use a 9mm socket wrench to tighten the nut on the push rod. Works great when there is a lot of space. The intake valve was a VERY easy job with this tool. I like the way it looks in old blued steel style.
