I picked up an 03 banshee, fresh rebuild.. guy shattered piston.. im guessing from running lean.. it had 260 mains, 25 pilots.. I went to a 300 main and a 30 pilot.. and im still getting lean condition.. greyish tan plugs.. more dark grey than tan.. funning bike runs great.. it has platinum pipes, pro circuit 304 silencers, v force reeds, no air box lid.. I just ordered 320 mains and 340's... my first banshee.. hoping for some insight.. I don't wanna mess up a new rebuild poking in the dark
