History: 2001 XR400 was burning oil like a 2 stroke...did a leakdown and determined it needed rings. So i have pulled the head and cylinder....valves are seated very well..I measured the cylinder with a bore gauge and i see that it is worn by about .05 mm, which is within the service limit of .1 mm according to my Clymer manual. My question is: Can I hone the cylinder and put new stock rings in it since it is within the service limit? or do I need to account for that .05 wear by going with rings and a piston that are .05mm oversize? Thanks!
