Three is supposed to be the indication to jump to the next pilot size. You should be running 25's if you've got an open airbox or higher depending on the rest of the bike and the location.

Ok thanks.3 turns out max.The air box is closed I just cut the flaps in the snorkel and the trimmed back the flaps in the air box cover so it will suck more air.The exhaust is stock and I also changed the main jets to 145/150.I thought it was going to run rich but the spark plug looks good.I guess it was a little lean from the factory.
