Service Manual Cylinder, Piston, Pin Measurements.

I'm looking to get the measurements for the cylinder bore, piston skirt clearance, wrist pin bore and so forth. My service manual is from my 2005 snopro 440 and doesn't have the 800ho measurements and specifications. Trying to determine a knock in the MAG side cylinder.

My cylinder is true, with only 0.003" out of round. Minimum is 3.3426" maximum is 3.3453"

My piston skirt clearance is 0.010" which is over double of the skirt clearance allowed compared to the maximum for the F7's. And 3 times the maximum for the 440's. (I suspect this is the knock)
Piston skirt 3.3356"
Cylinder 3.3448"

Wrist Pin clearance is 0.0005"
Pin 0.8650"
Piston Pin Bore 0.8655"

Connecting Rod small end bore is 1.0615"


If someone could snap a picture of their service manual showing the tolerances for my 2012 proclimb 800 that would be appreciated, I'd like to have it on hand.
