The first sign of being too lean will be popping during deceleration. If it does this, first try and open the fuel screw. Your stock setting should be 1 1/4 turns, go out a 1/4 turn at a time for a maximum of 2 turns. If it stops popping your ok. If it pops at two turns you need to go up 1 on the Pilot. Don't make mor than one recommended change to anything at one time. Otherwise you will wind up chasing your tail trying to get the carb right again. If it's not popping and your satisfied with the power......Just ride and roost...

Good Luck....
