250-500cc New Piston

Replacing the piston on 2008 WR250 what's the go on seating the new rings , Getting conflicting info some say do nothing others use a scotch bright pad to very lightly score the bore ? .

My cylinder at + - 60 hrs I did not touch walls this piston change

deglaze bore with green scotch brite pad and WD40, service power valve, wash all with soap and water, dry, oil the needle bearing/wrist pin with two cycle oil, do not oil the piston/rings/cylinder, install jug, no heat cycles, go ride normal after std warm up.

i dont do anything re cylinder unless ive junked it then its off for new nikasil!
i thought glazed bores only happen if you thrashed it mercilessly from brand new like no runing in procedure?
anyway install new rings piston torque or tighten everything double check and do a few heat cycles avoid high rpm and lug the motor more that usual, your trying to bed the rings into the bore.

Been doing a little more digging found this http://www.nzcylinders.com/Cylinder honing.html Thanks for the reply s
