Valve size

Post by larry202br »

I'm trying to find info on the valve sizes of a 65+ 110, and a 140. Can anyone tell me the diameters of the intake and exhaust?

Clark shows the 140 and (exc 140) sizes as:

exc 140:
Intake: 1.344
Exhaust: ?

140:
Intake: 1.723
Exhaust: 1.36

they show the (exc 140) exhaust as a 4 groove valve, but don't list a size. Does anyone know the (exc 140) exhaust valve size?
