like the title says, I have a set of cylinders for sale. They were remove from a running quad, I don't see any daage just need a hone and ready to go but I recommended to take them to a shop just to be sure. I'll include stock head and reeds and like a bonus a boost bottle!!! Sorry no piston they were sold, I have a set 64mm both I think you can use them.
