AT2 was created by RobertE

Does anyone know what the piston to cylinder clearance should be on a fresh bore for a 72 AT2??   The AT1 shows .0016-.0018, but the AT2 has a reed s;ystem and the piston is different. Would the specs be the same?

Whoops, finally found the tech manual for the 72. .0016-.0018 is correct for the AT2.

My book says "in mm" .040--.045mm which is the same as what you have in inches. My book says same for AT2 & AT3 etc. Think you measure it just above the windows as starts to taper if you go higher up, but measurement at the skirt base & 'there' should be the same. 18mm up comes to mind but that might've been YZ's with the cutaway skirt.
