I've had my cylinder measured with a 3 prong gauge,
Top just below TDC for rings:
71.993
71.993 (tool rotated 180 degrees)
Above ports
71.991
71.994 (tool rotated 180 degrees)
Below Ports
71.998
71.992 (tool rotated 180 degrees)
Bottom of skirt
72.00
71.998 (tool rotated 180 degrees)
So basically then it's 71.99 to 72.00 depending on where it's measured.
So if some parts are at 72 and the piston needs 0.06 to 0.1mm clearance and I aimed for 0.06 clearance I would need a 71.93 piston though I think the smallest available is 71.94 in a vertex. (if the 71.94 refers to the max piston diameter?)
Does anyone know what size the weisco is?
Does this make sense?
