I have a Gen 1 cowl on my Gen 2.
I had a seat custom made for my Gen 1 at Sargent and wanted to use it on my Gen 2.
Didn't work with the Gen 2 cowl so I bought a Gen 1 cowl and had it painted.
The fit is very acceptable although not perfect.
If you want to use the Gen 2 cowl, get a Gen 2 Corbin.
The seat you bought is a Corbin Gen 1 design.
I did a 700 mile day on one of them on my Gen 1 and loved the shape but it was a bit long for me and hard as a brick.
