2001 OX66 pistons

[KW2220CC]

motor is a LX200TXRZ , crank looks surprisingly good , cant feel anything with the fingernail , dropped it off at the machine shop today to get checked out .

After taking it apart I made the right call when I turned around at the end of the no wake zone , only had a half mile ride back to the dock

its hard to tell in the pic but the the bore doesnt look that bad above the ports , that would explain why the rings are tore up , I measured the ring in gap on that cylinder and the top ring was in spec

0.014 for the top ring and 0.015 for the bottom ring

rings arnt* tore up

Anybody know why the parts manuals show the #1 piston as a separate item but has the same part number as #3 and #5 ? the rings show the same part number

The year prior to your model year motor, two different pistons were used. One part number for cylinder #1 and a different part number for cylinders #3 and #5. See illustration below.

The following year, in the LX200TXRZ model ,Yamaha used the same piston part number in cylinders #1, #3 and #5. Rather than redo the illustration they simply changed the part number of the 67H piston to the 64D piston.

So no boring to the block, just a hone?
