Piston and Cylinder Clerance

[maddogwfo]

Question on 900 1M motor, I pulled my heads of this morning to check my pistons and cylinders for wear, wash looks great but my question is how much play or clearance should there be between piston and cylinder wall, there is no worn ridge at top of cylinders but there seems excessive play on between piston and cylinder wall, also what are torgue specs on heads, thanks for any imput, MADDOGWFO

a good stab at the clearance would be .15mm and the head torque specs are 22 ft lbs.

You can't check piston clearance by looking at the top of the piston. Above the ringland is considerably smaller than at the bottom of the skirt where you are supposed to check the clearance. Skirt clearance I believe is .00425-0059.
