Needing coolant tank and cap for FL400 pilot

I went this route. I know it’s not Honda, it’s not as big either but it is a different alternative. Motion pro makes it, 275cc overflow bottle. It attaches with zip ties. A lot of the dirt bike guys use them. Or you can look around at street bike overflow bottles.

I have one you can have for $25, it looks like it was repaired with devcon at the bottom but it works fine, only way I found out was when I took it off for my conversion.
