This Yamaha jug had some deep scratches in it that i tried to hone out.  No luck.  Got a 1mm over piston and sent it to the machine shop.  They said it needs to be bored 2mm over to straighten everything out.  Don't want to go that big so selling the jug. 

Ask all questions before bidding.  Happy to check anything you want.  Looking for a quick sale. Send me a message if ebay quotes a crazy shipping price.
