Yeah, the first change is at 600 miles. 16,000 thereafter.

As for the purpose of the transfer case, that's something I think about a lot as I stare lovingly at my R* in the garage. Musky, you're of course correct that it moves the power to the left side of the bike. But I can't help but wonder if there's more to it. I mean, why couldn't they just take the power off the right side? No, something tells me that they built the motor and trans as a unit and then someone over in the styling department said "It's too short front-to-aft. It must be ronger, like Evrolushon Motor and Transmishion." (Spelling for effect.) At this point a meeting was called and they all went out for sushi. When the first round of tuna rolls arrived one guy took two of them to form a mockup of the shafts, and he used a noodle to illustrate the chain driving the aft shaft. He was then elected, on the spot, to head up the Transfer Case Development Team. Working closely with the Styling Department, they zig-zagged the power from the output of the transmission, aft to a point close to the swing arm pivot and then over to the left side where the Styling guys capped it off with our stylized Star Logo pulley cover.

That's what I think happened, anyway
