Well, two ways to go on this one.

Rebuild or Crate Motor.

The Crate motors are available, new about $3000

Rebuild: new 490cc piston and cylinder/gaskets: $695

new crankshaft and connecting rod: $281

So for roughly half the price of new you can rebuild a beast of a motor and have the best of everything.

Good Luck!

The $ 695 price includes the cylinder and piston and gasket set.

Is there any other damage to the lower end? If not your in good shape, you can get a used piston and clinder off Ebay for next to nothing. I would take the engine out and clean it well to make sure there is no debris left in the tranny or head. If you only damaged the cylinder and piston your just damn lucky! If you buy an entire engine I'll buy the tranny from you! :twisted:
