00 cr 125 cyl- Eric

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

Im not sure if its 5mm but ive seen one erics done and the outer edges do come very close to the front transfers.

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.
