A long time ago Allan converted his Harley fork top clamp so it fits his Chief, because he was using a set of 4" Flanders risers. This top clamp has been laying in a box since he changed his riser setup the last time, but now it will be useful again.
As shown at the pictures, we have extended a set of cast harley risers and bolted them together with the top end of a set of Flanders risers, I think it looks really cool, it gives a strong and heavy look.
