    1999 gp1200

    I have a gp1200 with about 125hrs. Last summer the oil line that feeds the #3 cylinder came off. I tore the ski down and found damage to the cylinder and piston. Is it possible to just bore this cylinder and install oversize piston and rings? Leaving the other two cylinders stock. Thanks for any help.

    It is possible, but not recommended. I would either have it resleeved, or bore all three. You will cause extra wear on the crank bearings having a bigger piston on one cylinder. Also, go premix from here on out.
