Im running 40:1 and it runs like a dream on top, a little slow to the powerband on bottom. SPOOGES ALL OVER and im getting sick of ruining pants like crazy. Also where my silencer and head pipe meet and the silencer slips over, it spews all over and down all over the air box cover. i dont want to risk ruining the way it runs by jetting and running different mix or blowing it up by running too lean. what do i do first?
