leak jet question

[2002TRX400ex]

I have been reading alot of different posts and im trying to figure out where the leak jet is and what the stock number is and i understand changing to a 35 helps bog. Is the leak jet the same as the pilot jet?

Here (http://www.yamahaoftroy.com/fiche_s...4JT-1494F-01-00) is a link to buy a Leak Jet. It's on the bowl of the carburetor. It's not the Pilot Jet.
