Nels,
Welcome to the fold.
As was already mentioned, the levers are no big deal to change and the lightbar isn't either but you will need a second set of hands when you tackle that job. The lightbar really makes a difference in seeing and being seen at night. You can either go with the Triumph bar, or you can cobble one together with parts from JC Whitney and other sources. I have the factory bar on my '03 TA...
Ride safe...
