A while back, we purchased some fiberglass parts from Craig at Boxer Cafe. Craig has been great to work with and talk to. He even made a custom front fender specially for us.
As with building any custom bike, the parts you buy may not be perfect. They usually require some modification. But they are a great starting point.
The seat went to Autos International in San Diego for upholstery.
Thankfully, somebody in the upholster shop has a keen eye and noticed that the seat pan is slightly uneven. The tail sections (seat Cowl) and seat pan are not symmetrical parts but should fit the bike without uneven gaps and without looking crooked.
So the seat came back to my garage (that I recently renovated with the help of professionals from garage door repair dallas) with the foam attached and thankfully it did. I re-test fit everything and then shaved down some areas to even the gap between the tank and the seat.
Again, I’m glad the seat came back into my hands because I also realize that the foam was a bit too high. It made the seat just a bit too tall. I’m only 5’9″ and the bike’s owner is a bit shorter then I am. So some foam has to go so we can touch the ground with both feet.
