Alright! Way to get an awesome bike. As for the year, there isn't a huge difference at all that I know of other than the carb. Tilliston or Mikuni, or a Keihin. Mikuni is best
It is an awesome bike, but it isn't _really_ an Indian. It's actually a guy that bought the rights to use the Indian name and built a moped with a Honda PC50 engine. There are no mod parts but tuned just right with a derestricted muffler, it can hit 35-40.
There are 3 places I know of to get Indian parts.
2) Bob - the guy that bought the crates (email@example.com)
3) The usual peer to peer places
The BEST resource for EVERYTHING is a thread here.
