Brad,
Check out your local mechanics for any good 2-stroke dirt bike, quad or snow mobile shops. A 2-stroke is a 2-stroke when it comes down to it.
You will most likely need to "manage" the whole parts process, as well as supply details such as schematics, work shop details (torque, etc).
I would not suggest a dealer, as they are working the clock, and not going to put the time/detail into your bike a true 2-stroke tuner will do.
Beyond that, your true best bet is to use one of the more knowledgeable tuners outside your area, ship the engine and let them do the work. Forks and basic stuff like that any mechanic that works on a modern sport bike can handle.
I just shipped my RS engine from ATL to San Fran for like $120.00 to get it built, it was well worth it as the tuner went through and measured everything to make sure I knew what I had, and what I could continue to use doing new top ends.
