Do I need to make any adjustments to put it on?



Nope, no adjustments needed, it's just a swap.

Or should I just bring it to a dealer to do?



Depends on how mechanicly inclined you are. Pat has some great instructions here http://www.dinqua.com/Triumph/sprocket1.html. I had the dealer do mine. I think it took them about half an hour.

Does this sprocket have much of an effect on gas mileage?



Yes, since you'll be running more at lower RPMs, it will increase your mileage.

Anything else I should know?



It is one of the best least expensive mods you can make to improve performance. No more looking for sixth gear.
