help me id this piston

[BURKE_DADDY]

when i tore apart my engine these pistons were in it.i was wondering if these pistons were originally made for something besides the banshee but they made them work with my banshee.

under the arrow that points to the exhaust it has these markings

co 68.5

 

are these forged or cast?

also ive been trying to find forged 69mm pistons and ive had no luck finding anyone who makes them for a banshee. ive talked to james at passion he said i could use some Kawasaki JS440 Jet Ski pistons but reed windows needed to be cut into the intake side of the piston and i dont want to cut anything and take the chance of making the piston weaker by modding it.

should i settle for cast pistons or keep looking for some forged pistons?

 

thank you for any help you can give me.

Do you know who makes them I'm sure you could call the company to find out. Vitos has forged but there just wiesco made.
