A 6.5" long neck isn't one that takes the standard harley cups....too long. (EDIT: Duhh...I see now Browd allready pointed that out).

Sounds to me (but kinda just guessing here) that it's got an old ironhead/45" style neck on it.....they were shorter & took a 7/8" stem.
If that's the case, there's conversion cups out there to make it accept the longer/1" (big twin) harley stem (I think bros.manufacturing makes some...maybe others too?).  I think I've got an ironhead frame at work/ I'll try to check & compare for you asap......
