    Need Advice on replacing a holed piston

    I burned a hole in the PTO piston of my 96' slt 780 and will check my fuel, crank index and leakdown of crank case. It appears that my cylinder will have to be bored as the machine shop said honing will not cut it. I will then need an oversized piston and I understand that you should make all the pistons the same, which ends up costing a lot of money. Does anyone have a used standard piston and liner, so I don`t have to replace all 3?
    Guys, what would be your advice? Thanks Mike

    Talk to John Zigler. He may have a good used cylinder and piston for ya. I know he parted out a couple of 780s not long ago.
