2. Using micrometer, measure piston diameter.
3. Calculate cylinder bore diameter to be rebored as follows.
D = A + B - C
D: Cylinder bore diameter to be rebored.
A: Piston diameter as measured.
B: Piston clearance = 0.02 - 0.04 mm (0.0008 - 0.0015 in.)
C: Allowance for honing = 0.02 mm (0.0008 in.)
4. Rebore and hone cylinder to calculated dimension.
NOTE: Before reboring, install lower crankcase and tighten to specification to avoid distortion of bearing bores.
5. Measure piston clearance after honing.
