If you've been around a while you may remember the Honest Charley ads in Hot Rod magazine and other car mags back in the sixties. Back then, they were one of the premier speed parts suppliers. These days, "Honest Charley hisself" as they used to say has passed on but the name and trademark was purchased by Coker Tire and they continue the tradition of old time speed.
They started making Flathead motorcycles by taking old Ford Flathead V8 engines and installing them in a hardtail springer frame. These are all one off creations with some slightly different parts to make things work and no warranty of any kind is included. But if you're getting a flathead, that comes with the territory. Putting a big Chevy crate engine in a huge bike is one thing, this is a lot neater.
