Steve, not sure who I spoke with last on your end.  The Freemansburg Motorcycle Hill Climb (www.bikehillclimb.com) is Pro AMA Santioned event on June 8th and also Sept. 14, 2008.  Has your bike been santioned as a factory unit?  You may also want to rent our hill or be present to display your bike. Ultimate would be for you to compete in Stock Class.  let me know on the neck/front frame for trike and also if you have any interest in the Hill Climb.
