The issue with the starter system isn't the starter clutch, it's the starter idler gear. It should be upgraded to the '04 part which is a torque limiter, detailed nicely in this thread ->http://www.thumperta...tial-new-owner/. This upgrade eliminates the need for any woodruff key fix since there never was a woodruff key problem to begin with, rather a poorly designed starter system with an idler gear instead of a torque limiter. KoolAid probably knows the upgrade hasn't been done by the flat idler gear cover on the '03 -vs- the domed cover on the '04+ as can be seen on the left side of the bike.
Don't put much faith in the odometer reading since it's resettable, though it may be accurate based on how clean the bike looks. There is no visible wear on the clutch and stator covers or boot rub on the frame above the footpegs.
Street plating the bike depends on the laws in TX. I converted mine fairly easily in Maine, only adding a brake light switch and signals.
