Oil leak from Tachometer port is a common disease of air cooled Z.
If it starts leaking, replace it with this one.
The installation is a little hard, so apply more silicon grease and make sure to put it in straight.
You should also apply some anti-seize material to the screw holes of the Hexagon Bolt to prevent them from being damaged.
We will see how durable it is, but we think it is more durable than OEM.
The air-cooled Z has all the countermeasures and most of the parts are mechanical parts, so it is not likely to break suddenly and the maintenance cost is not much.
Looks like you access from European region.
