Does not seem to be correct piston although it is stamped "1.00".
The product quality appears very good but it does not appear to be the right size. It came with rings but did not come with a wrist pin or wrist pin clips. The well used box has the right part number 13105-030-000. The box top has C200 written on it along with 1.00 but the top is loose and not attached to the rest of the box. The piston is new with 1.00 stamped on the top. The "1.00" piston diameter is 1.963 in. The 90cc stock piston should be 1.9673 - 1.9681 so this "1.00 over" piston actually appears to be stock. A 1.00 over piston should be 0.040 wider than normal so this one should actually measure close to 2.000 in.
