depending on which bore your at

you could possibly get a used set from somebody off this forum

 

then jsut have the juggs bored and use the much less expensive pistons with new rings

top end jobs on a banshee can allmost be done with your eyes closed

its just a super simple machien to work on

 

if you lived by me i woudl help you do it evan

[frocashmoney24]

damn ur pistons and jugs look rusty.. i'd hone the clyinders, and get some new pistons the same size, but before you do that, do a compression test

[Noob Banshee]

why? and how?

Do you have a air conpressor? Blow those cylenders out. You need the head on to get a compresson test. Was it hard to start? Or had no power? Why did you take the head off? Run those pistons up to the top and take your pocker knife and clean the carbon off and see if there is any numbers, like .020 or .030 etc. When you know what the bore is then you can have a machine shop mic the bores to see if they need to be bored.
