Thought this would be the best place for advice on my 82 250r. We are rebuild ing the top end right now. Have a few questions on piston size. Want to leave it stock but right now has no power band at all. Bottom end makes a bearing type rattel almost a grind. Any ideas?? If anyone Knows the piston size for a stock 82 250R and how much space to leave in the ring that would be great!! Also want to put smaller tires on front and back any suggestions?? 8)

the bore is 70mm (2.756 in)

and why would you want to convert it to 4 wheels???
