Finally went and got my head out of storage, and took a couple measurements. It has almost a 42mm port opening, and slowly tapers a little down to 39.5mm at the seat I.D. The intake valve is 42.5mm
A picture of the port , so anything in the 30's won't work. Head flows just over 200cfm. http://i88.photobucket.com/albums/k168/minidragbike/20140213_114058_zpsexuz2adx.jpg
