I have a FB 460 kawi i think its a so7. My issue is when it leavel it never smokes or when the air box is pointed up hill its okay. The problem is when the air box is pointed down hill it smokes like a fog machine. Then i make my turn and go across the other way it calms down. Where should i start? Also would a FH381V kawi bolt in its place? any ideas thanks for the help Checked the compression it is with in limits a bit over 50 psi that was with a hot engine
