I was replacing my Duke with a Vanilla R. I removed the crown race from the Duke and then tried putting it on the Vanilla, but it just fits right on the Vanilla. It makes contact all the way around but it is not snug. I can install and remove by hand. What could be the problem. The Duke was the stock fork that came on the bike and the headset is stock as well. I got the Vanilla off of Ebay, and it is an OEM model that has was removed before use. Does anyone know what could be up? Thanks for any responses.
