According to Erics book the outer edges of the exhaust port should be turned down 5mm is this a typo and maybe it should be .5 or am I missing the picture. At 5mm I'll be somewhere in the middle of the front transfer. Thanks
Minutz,
Since 2000, Honda changed the exhaust port shape in a similar way. The outer edges are lowered to get more area before the transfer ports open, and yes its 5mm.
