Got this done last night, too. Since I had the CVT over off, spun the motor over that way. Even with the plugs out, the motor doesn't turn over real easily. I just followed the lines on the cam sprocket to make sure at TDC, and then struck a screwdriver down the spark plug hole to make sure the piston was at top. Hard to get the feeler gauge in there. Front cylinder was pretty tight, rear cylinder a little closer to spec.
