Desert Wind (formerly Chosas) in Mesa is not a massive H-D dealer. Neither is Chandler HD. The big one is in Scottsdale, when you go... you'll see what I mean. IIRC they have a tattoo shop, a barber, arcade, movie theater and dedicated BBQ/eating area on site. I'm sure there are other things also. I'm pretty sure Scottsdale HD is owned by the same people who own GoDaddy. I've had good luck ordering Buell parts from Scottsdale . However, I always bring them part numbers and they never blink an eye.
Chandler HD used to be a Buell dealer, and would have some Buell parts in stock. I think they were purchased and are now a part of the conglomerate that owns Rumble On. They used to be my go-to dealer to order Buell parts, but over that past years they seem to be blowing through parts dept employees, including managers. They used to be "Buell friendly", but now you dont know what you're going to get.
