Sorry I miss read you're comment, I'm not sure if they have the pistons on hand at the shop or not

I'm not sure if there boring them on hand, I dropped them off three days ago he said he would call me and let me know what needed to be done, still haven't heard from him and I tried calling no answer hoping to here back soon so I can figure out what piston size to order.I was looking into the 392 assassin big bore kit also has anybody had experience with this kit or heard anything good or bad about it?

Thank you for the advice I appreciate it, I ended up calling around and found a shop that said they would do it for 60 a cylinder. I dropped it off a few days ago waiting to here back if it will need a bore or hone.

Hey everybody this is my first post on here! I just recently picked up a 1987 Banshee it was running when I got it but very low compression so I decided to start tearing it down. The pistons that were in it are 66.25 mm and the cylinders look like they could use a bore so my question is should I get the cylinder bored out for a 66.5mm piston or would that be pushing the stock Jug? I called the local Yamaha dealer they said they wanted $125 per cylinder to bore them which seemed pretty expensive? I was looking at some big bore rebuild kits but I don't know much about whats out there, If anybody could give me any suggestions on what I should do i would really appreciate it! Thanks, Mike.
