Sold the bike a few weeks ago to fund the next project, but yes. The stock C shocks are too short. At 200lbs, I had to crank the preload almost all the way up. It only contacted the fender on speed bumps and curbs though, which is also why I welded the fender mounts to the top so it was all smooth underneath. F or K shocks bolt right up and are perfect, but the ones I got had blown seals.
That being said, the geometry felt nice at that ride height - leaned well, was decently stable, and overall was a nice ride.
And yes, that's a 6" wide custom rear fender cut to length and with custom brackets for the frame.
If I were to do it again I would do a kick up in the frame at the rear or a stepped seat. You do slide off if you're not paying attention.
