I have no where near that - but that is not high mileage yet. The old Bullets used to need a bit of work, when they got to 50,000, with the Indian models I would assume a little less, before rebuilds are needed. But, it all depends on how you treat the bike - I have seen one, cleaned regularly, but mechanically ignored, that needed a complete rebuild after 12,ooo miles. The most I have heard of, on the same engine, is a guy in Madras with 190,000 miles.
