Take off the seat. Find the bent rubber pipe looking thing sticking out of the top of the airbox. Give it a squeeze where it goes into the airbox to get the latching tabs clear of the airbox cover and pull it out.
Part 2:
remove the little boxy cover on the left top of the airbox that hides a wire connector. Take out the 3 screws (maybe 4, I forget) that hold the oval cover to the airbox in place. Remove the cover, then reach in and lift out the air filter. Reach in and feel around toward the front of the bike till you find the air tubes leading forward to the carburettors. If they have rubber tubes in them, pop them out the same way you did the main snorkle. Replace the air filter (open end up!), the 2 covers you removed ant the seat. Then, go enjoy having 2 - 3 more HP!
